The 7 Best Electric Pressure Washers in 2026

1. What Electric Pressure Washers Do Well

Electric pressure washers are not simply weaker gas machines. They are better at several specific jobs, and knowing which ones prevents both disappointment and unnecessary spending on gas equipment.

Vertical surfaces are their natural home. Siding, fences, garage doors, and exterior walls all want moderate pressure and careful control rather than raw volume. An electric machine at 2000 to 2300 PSI cleans them effectively without the risk that a high-output gas machine brings, and being quiet enough to hear yourself think while working makes the job less unpleasant.

Vehicles are safer with electric. Automotive paint tolerates roughly 1,500 PSI, and a gas machine at 3,000 PSI is a tool you must actively restrain. Electric machines land naturally in the right range, and several offer surface-specific pressure control that makes damage genuinely unlikely.

Frequent short jobs favor electric. Cleaning patio furniture, rinsing a walkway, or washing garbage cans is a five-minute task, and a machine you plug in and switch on gets used for that. A gas machine that needs checking oil and pulling a cord does not, which is why gas washers often sit unused for jobs an electric one would have handled.

Storage and noise matter more than people expect. An electric unit stores on a shelf, needs no fuel in the garage, and does not require hearing protection. For an apartment, a townhouse, or a home with limited garage space, those practical factors often outweigh cleaning speed entirely.

Where they genuinely fall short: large flat concrete. Water volume is what carries dirt away and covers area, and 1.2 to 2.0 GPM against a gas machine 2.4 to 3.5 GPM is a gap that shows up directly in hours spent on a driveway.

2. The 7 Best Electric Pressure Washers in 2026 — Tested & Ranked

We cleaned vinyl siding, a weathered wood deck, a cedar fence, a vehicle, and a section of concrete driveway with each machine, timed coverage, measured noise, and ran extended sessions to check for heat-related power fade and pump behaviour. These seven earned their place.

Cleaning units are PSI multiplied by GPM. Street prices move constantly, so treat the figures in each review as a guide and check the current listing.

Almost every complaint about electric pressure washers, that they are loud, that they get hot, that they die after two summers, traces to the universal motor most of them use. The RY142300 uses a brushless induction motor instead, and the difference is immediately obvious. It was the quietest machine in our entire test group, gas or electric, running at a level where conversation nearby is easy. Over extended sessions it showed none of the power fade that heat-soaked universal motors produce, and the housing stayed cool enough to touch. At 2300 PSI it sits at the higher end of the electric range, and in our testing it cleaned vinyl siding, a weathered wood deck, a cedar fence, and patio furniture without difficulty. On concrete it works, though the 1.2 GPM water volume means a driveway takes real time, and a surface cleaner attachment is close to mandatory if you plan on that job regularly. The on-board storage is a genuinely useful design touch, keeping the hose, cord, wand, and all five nozzles on the unit rather than scattered across a garage shelf. The trade-offs are throughput and price. Water volume is the specification electric machines cannot escape, and 1.2 GPM is modest even for the category. It also costs meaningfully more than budget electric units, which is exactly the point: you are paying for a motor that lasts.

Pros

• Brushless induction motor is quiet, runs cool, and lasts far longer than universal motors
• 2300 PSI is genuinely high for electric, handling siding, decks, fences, and light concrete
• On-board storage for hose, cord, wand, and all five nozzles keeps everything together
• Quiet enough to run in a driveway without disturbing the whole street
• Solid frame with real wheels rather than the small plastic casters on cheap units

Cons

• 1.2 GPM water volume makes large flat concrete areas slow going
• Costs meaningfully more than budget electric washers
• Hose is on the shorter side, limiting reach without an extension

The Bottom Line

The electric pressure washer worth paying for. The induction motor is the whole reason, and it will outlast three cheap machines.

The standard argument for gas is that electric machines cannot handle concrete, and the GPW3000 is the clearest counterexample in this guide. At 3000 PSI and 2.0 gallons per minute it produces 6,000 cleaning units, which puts it in the range of entry-level gas machines and roughly double what a typical budget electric unit manages. In our driveway testing it actually removed embedded algae and dirt rather than merely brightening the surface, which is where lower-output electric machines run out of capability. Build quality supports the output. The steel frame and larger wheels make it genuinely movable across a lawn or gravel drive, unlike the small plastic-framed electric units that have to be carried. The induction motor gives it the quiet operation and long service life that separate serious electric machines from disposable ones. For a homeowner who wants a driveway-capable washer but has no interest in owning a small engine, this is the most direct answer available. Two practical points. It draws substantial current, and sharing a circuit with other loads will trip breakers, so a dedicated 20-amp circuit or a heavy-gauge cord on its own circuit is worth arranging before the first use. And despite the pressure, 2.0 GPM is still below any gas machine, so a surface cleaner attachment is how you close the remaining speed gap on flat concrete.

Pros

• 3000 PSI at 2.0 GPM gives 6,000 cleaning units, which genuinely cleans concrete
• Induction motor for durability and lower noise than universal motor machines
• Steel frame and larger wheels that roll over grass and gravel properly
• Closes most of the practical gap to entry-level gas machines
• No engine to maintain, fuel to store, or oil to change

Cons

• Draws enough current that a dedicated 20-amp circuit is strongly advisable
• Heavier and bulkier than typical electric pressure washers
• Still slower than gas on large flat areas because of lower water volume

The Bottom Line

The electric machine for people who want to clean concrete without owning an engine. It genuinely does the job.

The SPX3000 has been among the best-selling pressure washers in the country for years, and the reasons are straightforward: it costs a fraction of a gas machine, it produces enough pressure and water volume to clean siding, decks, fences, furniture, and vehicles effectively, and it is small enough to store anywhere. For a homeowner who pressure washes a handful of times a year, that covers the real demand at minimal cost. Its dual detergent tanks are genuinely unusual at this price. Keeping a house wash in one tank and a degreaser in the other, and switching between them with a dial rather than draining and rinsing, is more convenient than most machines costing several times as much. The Total Stop System is the other important feature, cutting the pump when the trigger releases, which prevents the heat buildup that destroys pumps left running in bypass. The honest limitation is the motor. This uses a universal motor, which is why it is loud, why it heats up during long sessions with noticeable power fade, and why its expected service life is measured in a few seasons of regular use rather than a decade. The plastic frame and wheels reflect the same economics. Framed as an inexpensive tool with a finite life, it is a reasonable purchase. Framed as a long-term investment, it is not.

Pros

• Very inexpensive while delivering usable 2030 PSI and a respectable 1.76 GPM
• Two onboard detergent tanks let you switch soaps with a dial rather than draining and refilling
• Total Stop System cuts the pump when you release the trigger, which extends pump life
• Light and compact enough to carry with one hand and store on a shelf
• Five quick-connect nozzles included covering every common task

Cons

• Universal motor is loud and has a considerably shorter service life than induction
• Almost entirely plastic construction, including the wheels and frame
• Runs hot during extended sessions, with noticeable power fade

The Bottom Line

Cheap, popular, and genuinely functional. Buy it knowing it is a few-seasons machine rather than a decade-long one.

Every other machine in this guide needs both a spigot and an outlet, which is a real constraint more often than people expect: a boat on a trailer, a fence at the far end of a property, a cabin, a work site. The EGO cordless pressure washer needs neither. It runs on the same 56V batteries as the rest of the EGO lineup, and it can draw water from a bucket, a barrel, a lake, or any standing source through its intake hose rather than requiring pressurized supply. That combination genuinely enables jobs the others cannot attempt. Peak pressure is competitive with corded electric machines, and in our testing it cleaned patio furniture, a boat hull, and a section of fence effectively. Operation is near silent and there is no cord to route, tangle, or trip over, which makes moving around an object being washed far easier than it sounds. The costs are runtime and price. Battery capacity limits sustained work, and even a large pack does not last a full afternoon of continuous cleaning. It is also expensive, particularly as a kit. And sustained output sits below a good corded machine, because a battery cannot supply the same continuous power a wall outlet can. Buy it for the portability, which is genuinely unmatched, rather than expecting it to outperform a corded unit at a spigot.

Pros

• Completely cordless, so it works anywhere including places with no outlet at all
• Can draw water from a bucket, lake, or rain barrel rather than requiring a spigot
• Peak pressure competitive with corded electric machines
• Runs on the same 56V batteries as EGO mowers, blowers, and trimmers
• Extremely quiet and instantly ready with no cord to route or trip over

Cons

• Runtime is limited, typically well under an hour on a large battery
• Expensive, particularly once a large battery and charger are included
• Lower sustained output than a good corded electric machine

The Bottom Line

The only pressure washer that goes anywhere. For boats, remote fences, and job sites without power, nothing else does this.

The most useful thing about the ePX3100 is that it brings an induction motor down to a price point where budget machines with universal motors normally live. That single specification is the strongest predictor of how long an electric pressure washer lasts, and getting it without paying premium pricing is genuinely good value. In our testing it ran noticeably quieter and cooler than the universal-motor machines at comparable output, and it showed none of the power fade that appears in cheap units during extended sessions. At 2050 PSI and 1.76 gallons per minute it produces around 3,600 cleaning units, which handles siding, decks, fences, furniture, and vehicles comfortably and makes light concrete work feasible if slow. The Total Stop System protects the pump by shutting it off when the trigger releases, and a soap tank is integrated rather than requiring a separate siphon setup. The compact vertical design is the other appeal, storing in a fraction of the floor space a horizontal machine needs, which matters in a crowded garage. That same compactness is its main ergonomic weakness: the narrow footprint makes it somewhat tippy when you drag the hose sideways, and it needs repositioning more often than a wider machine. The cord is also shorter than some competitors, and the included accessories are functional rather than notable.

Pros

• Induction motor at a price close to universal-motor budget machines
• 2050 PSI at 1.76 GPM gives a solid 3,600 cleaning units for the money
• Very compact vertical design that stores in minimal floor space
• Total Stop System and a soap tank included
• Quieter and cooler running than budget competitors at similar output

Cons

• Compact design makes it slightly tippy when dragging the hose
• Shorter power cord than some competitors
• Accessory quality is adequate rather than impressive

The Bottom Line

The value sweet spot. An induction motor at close to budget pricing means it should outlast the cheap machines by years.

Most electric pressure washers are designed as though they will live permanently in the middle of a garage floor, and the DWPW2600 is the clearest exception. Its roll-cage cube frame stacks, stores on a shelf, and swallows every accessory: the nozzles clip to the wand, the hose tucks inside the cage, and the cord wraps at the back, which in practice means nothing goes missing between jobs. That sounds like a minor convenience until you compare it against a season of hunting for a black soap nozzle in a bin. The more important point for this guide is the rating. DeWalt publishes its figures as CETA-certified, measured at the nozzle with a reference tip, rather than the internal PSI Max numbers several competitors print on the box. When this machine says 2600 PSI, that is roughly what you get, and in our testing it cleaned vinyl siding, a cedar fence, and a weathered deck at a pace consistent with that figure. Two real limitations. The motor is universal rather than induction, so it is louder, runs hotter, and should be expected to last seasons rather than a decade, which is the same trade the Sun Joe machines make at a lower price. And at 1.1 GPM it moves the least water of anything here, so flat concrete is slow going and a surface cleaner is close to mandatory if a driveway is on your list. The small wheels also do poorly on grass and gravel, though at around 40 pounds it is light enough to simply carry.

Pros

• CETA-certified performance, so the 2600 PSI figure is measured at the nozzle rather than inside the pump
• Roll-cage frame stacks and stores in a fraction of the space of an upright cart machine
• All five nozzles, the wand, the hose, and the cord store on board with nothing left loose
• 2600 PSI handles siding, decks, fences, and light concrete without complaint
• Also sold in 2100 PSI and 3000 PSI versions if you want a different balance

Cons

• Universal motor, so expect a shorter service life than an induction machine
• Small wheels struggle on grass, gravel, and bare ground
• 1.1 GPM is the lowest water volume in this guide, which slows flat concrete work

The Bottom Line

The best-designed machine here for storage and transport, with a certified pressure rating you can actually trust. Buy it for the packaging, not the motor.

3. PSI, GPM, and Cleaning Units: The Math That Compares Machines

Two specifications describe what a pressure washer does, and most shoppers only look at one of them. PSI is pressure, the force that breaks dirt loose. GPM is flow, the water volume that carries it away and covers area. A high-PSI, low-flow machine strips a stubborn patch beautifully and takes all afternoon to do a driveway. A high-flow, low-PSI machine covers ground quickly and leaves embedded algae behind.

The number that actually compares two machines is the product of both, commonly called cleaning units: PSI multiplied by GPM. It is the closest thing this category has to a single measure of capability, and it is why a 2,000 PSI machine moving 1.76 GPM out-cleans a 2,300 PSI machine moving 1.2 GPM despite the lower headline figure.

Note what the second row shows: the machine with the lower advertised pressure delivers roughly 30 percent more cleaning capability. If you compare only the number printed on the box, you will systematically pick the wrong machine.

How Much Pressure Each Surface Actually Wants

More pressure is not better. Above the level a surface tolerates, you stop cleaning and start removing the surface, and wood, paint, and mortar do not grow back. Use the widest nozzle that does the job, and step down in angle only if it does not.

4. PSI Max, GPM Max, and Why Certification Matters

Here is the part of this category that nobody selling you a machine wants to explain. The pressure figure printed in large type on the box is not governed by any law, and some brands measure it in the place where the number comes out highest — inside the machine, at the pump, with no nozzle fitted — rather than at the nozzle where the water actually meets the dirt.

That figure is usually flagged with an asterisk and the word Max: PSI Max, GPM Max. It is not necessarily a lie, but it describes a pressure you will never experience while cleaning anything. Two machines advertised at 3,000 PSI can differ by a wide margin in the real world if one number is certified at the nozzle and the other is an internal maximum.

How to check before you buy. Look on the spec sheet or the box for a PWMA or CETA logo, or the phrase "certified performance". If the listing quotes PSI with an asterisk, find the footnote — it will usually tell you the figure is measured internally. If pressure and flow are quoted without any nozzle reference and the machine is unusually light for its claimed output, treat the number as optimistic.

Not every uncertified machine is overstating. Some manufacturers with strong reputations have simply not enrolled particular models in a certification programme, and their figures hold up in testing anyway. Certification is evidence, not the only evidence. But between two machines at the same price where one is certified and one prints a Max figure, the certified one is the safer purchase and it is not close.

Where this bites hardest is the budget shelf. The gap between advertised and delivered pressure tends to widen as price falls, which is exactly where buyers are most reliant on the printed number. If you are shopping under $200, weight and motor type tell you more than the PSI figure does.

5. Induction vs Universal Motors: The Spec That Decides Lifespan

This is the most consequential specification on any electric pressure washer, and a large number of product listings do not mention it at all. Knowing how to tell them apart is worth more than comparing PSI figures.

Universal Motors

Universal motors use carbon brushes and a commutator, spin at very high RPM, and are small, light, and cheap to manufacture. They are also loud, run hot, and wear out as the brushes degrade. In an application like a pressure washer, where the motor runs continuously under load, that heat and wear accumulate quickly. Expect a few seasons of regular use rather than a decade, and expect noticeable power fade partway through a long session as the motor heats up.

Induction Motors

Induction motors have no brushes, spin at lower RPM, and are physically larger and heavier. They run cool, run quiet, and last for thousands of hours. In our testing induction-motor machines were dramatically quieter, showed no power fade over extended sessions, and stayed cool enough to touch. This is the technology used in commercial pressure washers for exactly these reasons.

How to Tell Which You Are Buying

If the listing does not say, weight is the best proxy: induction motors are substantially heavier, so a very light machine with high claimed pressure is almost certainly a universal motor. Price is the other indicator, since induction machines cost more to build. Manufacturers that use induction motors advertise it prominently, so silence on the specification generally means universal.

When a Universal Motor Is Fine

If you will use the machine a handful of times a year for short sessions, a universal motor at a low price is a defensible choice, and the money saved is real. The mistake is buying one expecting a decade of regular service, which is where the disappointment and the poor reviews come from.

Axial Cam vs Triplex Pumps

The motor gets the attention, but the pump is what wears out second. Almost every consumer electric machine uses an axial cam pump, where the pistons sit in line with the driveshaft. They are compact, cheap to build, and give years of service in household use, and there is nothing wrong with one. Triplex pumps run three pistons off a crankshaft, run cooler, last far longer under sustained load, and are usually rebuildable rather than disposable — which is why they appear on commercial machines and almost never below $1,000. If you are cleaning professionally, look for a triplex. If you are cleaning your own house, an axial cam pump treated properly will outlive the motor in front of it.

6. Corded vs Cordless vs Hybrid vs Wall-Mounted

Electric used to mean one thing. It now covers four quite different machines, and picking the wrong format is a more expensive mistake than picking the wrong pressure rating.

Corded

The default, and still the right answer for most people. Unlimited runtime, the lowest cost per cleaning unit, and nothing to charge. The trade is that you are tethered to both an outlet and a pressurised water source, which around a typical house means dragging an extension cord and a garden hose to wherever you are working.

Cordless

Battery machines have become genuinely capable rather than novelties, and the best of them out-perform mid-range corded units. Two things make them worth the premium: no outlet to find, and a siphon hose that draws from a bucket, lake, or water butt when there is no spigot. The limit is runtime. Expect to manage power modes and swap batteries, and expect a full driveway to be a stretch even on high-capacity packs.

Hybrid

A newer format that runs from either mains power or batteries, so you get cordless freedom for quick jobs and unlimited runtime for long ones. It is the most flexible option and the most expensive, and it only makes sense if you already own batteries in that manufacturer's system or intend to.

Wall-Mounted

A permanently installed unit with a retractable hose reel, mounted in a garage or on an exterior wall. Nothing to drag out and nothing to store, which in practice means it gets used for five-minute jobs a cart machine never gets used for. It requires installation and a nearby water and power supply, and it is not going anywhere with you.

Pressure Washers vs Power Cleaners

A separate class of tool has appeared that looks like a cordless pressure washer and is not one. Power cleaners — the Worx Hydroshot and similar — are self-contained wands that typically produce 300 to 600 PSI, against 1,500 PSI and up for a real pressure washer. Flow can be comparable, which is why they rinse a bike, a kayak, or muddy boots perfectly well, and why they are useless on a driveway. If a listing quotes pressure in the hundreds, you are looking at a power cleaner, whatever the title says.

Wheels, Weight, and Where It Lives

The specification nobody reads and everybody regrets. Small hard casters roll fine on a smooth garage floor and dig in on grass, gravel, and bare ground, which is exactly where you use the machine. Large-diameter or wide wheels roll over rough terrain properly. It is not a deal-breaker on a light machine you can simply carry, but on a 60-pound unit it decides whether the thing gets used. Check the hose length and cord length while you are there: every extra foot is one less trip back to reposition the machine.

7. Water Supply, Cavitation, and Why Pumps Fail

Electric pressure washer pumps almost always fail for reasons unrelated to the electrical side, and understanding the water side prevents nearly all of it.

The pump must never be starved of water. A pressure washer pump is designed to move a specific volume, and if the supply cannot deliver it, the pump draws air along with water. That produces cavitation, tiny vapor bubbles collapsing violently inside the pump, which erodes seals and valves rapidly. A machine that stutters, pulses, or produces inconsistent pressure is usually cavitating rather than failing electrically.

Use a short, wide garden hose from a fully open spigot. A 5/8-inch or 3/4-inch hose no longer than about 25 feet, connected to a spigot opened all the way, gives the pump the supply it needs. A long, narrow, or kinked hose is the most common cause of supply starvation, and it is completely invisible as a problem until the pump fails.

Turn the water on before starting the machine. Starting a pump dry, even briefly, damages seals. Connect the hose, open the spigot fully, squeeze the trigger to purge air from the system until water flows steadily, and only then switch the machine on.

Do not run in bypass. With the machine on and the trigger released, water circulates inside the pump and heats up quickly. Sustained bypass is the leading cause of pump failure across all pressure washers. A Total Stop System shuts the machine off automatically when you release the trigger, which is why it is a feature worth insisting on.

Clean the inlet screen. A small filter at the water inlet catches grit that would otherwise reach the pump, and it clogs gradually. A partially blocked screen starves the pump with no symptom other than reduced pressure that people usually blame on the machine wearing out. Pull it and rinse it a few times each season.

8. Nozzles, Detergents, and Attachments

On an electric machine, where you have less raw power to spare, choosing the right nozzle and using detergent properly matter more than they do on a high-output gas unit.

The Nozzle Colors

Red is 0 degrees and concentrates everything into a pencil jet that damages almost any surface. Yellow is 15 degrees for aggressive work on hard surfaces. Green is 25 degrees, the general-purpose choice. White is 40 degrees for siding, vehicles, and delicate materials. Black is a low-pressure soap nozzle, and it is the only one that will draw detergent through the machine.

Detergent Only Works at Low Pressure

The black soap nozzle exists because the detergent siphon only engages at low pressure. Trying to apply soap through a high-pressure tip simply will not draw it, which is the most common reason people conclude their detergent system is broken. Apply soap with the black tip, let it dwell for several minutes without drying, then switch to a rinsing tip.

Let Chemistry Do the Work

This matters more on electric machines than gas ones. A proper cleaner that dwells on the surface breaks down algae, mildew, and road film chemically, so you need far less pressure to remove it. On a deck or siding, a dedicated cleaner applied first turns a marginal electric machine into an entirely adequate one.

Surface Cleaners Close the Concrete Gap

A surface cleaner is a shrouded disc with rotating jets that you push across flat concrete. It roughly doubles cleaning speed and eliminates the striping that hand-waving a wand always produces. Check that your machine has enough output to spin one, since some require a minimum GPM, and confirm the fitting matches your machine rather than being proprietary.

Extension Wands Beat Ladders

A telescoping wand lets you reach second-story siding and soffits from the ground. Using a pressure washer from a ladder is genuinely dangerous because of recoil, and an inexpensive extension eliminates that risk entirely.

9. Technique and Safety

Start Wide, Start Far Back

Begin with the widest nozzle you have, standing roughly ten feet from the surface, and close the distance gradually while watching what the spray does. If the widest tip at close range still is not shifting the dirt, step down one nozzle angle — not three. This single habit prevents almost every case of etched siding, furred wood, and stripped paint, because you discover the surface's limit before you cross it rather than after.

Keep the Wand Moving

Cleaning is a function of dwell time as much as pressure, so a stationary stream removes progressively more material from one spot. Sweep in steady, overlapping passes at a constant distance and angle. Pausing mid-stroke is what produces the tiger-striping on decks and driveways that people blame on the machine.

Work Top to Bottom, Rinse Bottom to Top

On siding, apply detergent from the bottom up so it cannot run down dry surfaces and streak, then rinse from the top down so the dirt has somewhere to go. Spraying upward under lap siding drives water behind the boards and into the wall, so keep the stream angled downward or level on vertical surfaces.

Stance and Kickback

A pressure washer pushes back, and more so with narrow tips. Feet shoulder-width apart, one foot slightly forward, knees soft. Reposition yourself and the machine rather than overreaching, and never operate one from a ladder — the recoil is exactly the force that puts people on the ground. A telescoping extension wand costs less than an emergency-room visit.

What Not to Spray

Electrical anything: outdoor outlets, light fixtures, meters, and "weatherproof" speakers, none of which are rated for a directed high-pressure stream. Also avoid air-conditioner fins, window seals and old glazing, roof shingles, lead-painted surfaces, and anything with soft mortar. Plug the machine into a GFCI-protected outlet, and if you use an extension cord, make it a heavy-gauge outdoor-rated one and keep the connection off wet ground.

10. Storage, Freeze Protection, and Longevity

Electric pressure washers have no engine to winterize, which leads people to assume no winter preparation is needed. The pump still needs protecting, and freezing is the most common way these machines die.

Water left in the pump will crack it. Water expands as it freezes, and a consumer pump housing is not designed to survive that. A cracked pump is a terminal failure on most electric machines because the pump is not economically replaceable. This is the single most common cause of an electric pressure washer that worked fine in October and does nothing in April.

Run pump antifreeze through it. After the last use of the season, disconnect the water supply and draw pump saver antifreeze through the machine until it comes out of the wand. This displaces the water and lubricates the seals, which also prevents them from drying out and hardening over months of storage.

Store it above freezing if you can. A heated basement or a conditioned space removes the risk entirely. An unheated garage in a cold climate does not, even if it rarely freezes hard, because a single overnight freeze is enough.

Coil the high-pressure hose in large loops. High-pressure hose is stiff and takes a permanent set if coiled tightly or crushed under stored items. A kinked hose can burst under pressure, which is both dangerous and an expensive replacement. Hang it in wide loops rather than piling it.

Store the wand and nozzles together. Losing the black soap nozzle is remarkably common, and it is the one you cannot substitute for, since it is the only tip that lets the detergent siphon engage. Machines with on-board nozzle storage largely solve this; if yours does not, a small box on a shelf works.

Check the cord before each season. Pressure washers involve water and electricity in close proximity, and a nicked or cracked power cord is a genuine hazard. Inspect the full length, and always plug into a GFCI-protected outlet, which most machines require anyway.
