A winter of algae, pollen and tracked-in dirt turns a concrete or paver patio dull and slippery. A pressure washer for patios strips that layer in an afternoon, but the right machine depends on your surface and the size of the job. Too little pressure and flow means slow, streaky work; too much, with the wrong nozzle, can etch concrete, scar soft stone or blow the sand out of paver joints. This guide compares current electric, gas and cordless pressure washers on the numbers that matter for hardscape cleaning, and adds practical safety notes on electrical protection, carbon monoxide and runoff.

The best pressure washers for patios
1. Westinghouse WPX3000e Electric Pressure Washer — Best overall for patios and driveways
A 3,000 max PSI electric washer with a three-piston axial pump, 25 ft hose, five nozzles and a 35 ft GFCI cord.
Check price on AmazonWhy we like it
- Highest pressure of any electric washer on the shelf
- M22 fittings accept surface cleaners and foam cannons
- 35-foot cord with GFCI protection
- Steel frame on 10-inch never-flat wheels
- 3-year limited warranty
| Specification | Details |
|---|---|
| Pressure | 3,000 max PSI, 2,600 rated PSI |
| Flow | 1.76 max GPM, 1.1 rated GPM |
| Hose and cord | 25 ft high-pressure hose, 35 ft GFCI cord |
| Nozzles | 0, 15 and 25 degree, soap and turbo |
| Soap | 0.45 gallon onboard tank |
| Weight and warranty | 36.8 lb; 3-year limited |
Westinghouse WPX3000e — 3,000 max / 2,600 rated PSI, 1.1 rated GPM, 25 ft hose, 35 ft GFCI cord, 36.8 lb
The highest-pressure electric washer among the 15 listings
Six corded Westinghouse electrics appear on the shelf, rated between 2,100 and 3,000 max PSI. The WPX3000e sits at the top, and its 2,600 rated PSI is also the highest working pressure of any electric listing. That extra headroom matters on concrete driveways and stained pavers, where a surface cleaner needs pressure to work well.
It is one of only three listings that mention M22 accessory compatibility, so a flat surface cleaner can attach directly to the gun. The listing also states a 35-foot GFCI cord, a 25-foot hose, five quick-connect nozzles and a 0.45-gallon soap tank, which is larger than the 20-ounce tanks on the compact models.
The trade-offs are size and flow. At 36.8 pounds and over 3 feet tall, it is a cart rather than a carry unit. Its rated flow of 1.1 GPM is slightly lower than the compact Westinghouse models’ 1.2 GPM, so rinsing large areas takes a little longer than raw pressure suggests.
Pros
- Top electric pressure on the shelf
- Direct surface cleaner compatibility
- GFCI cord stated in listing
- Large soap tank
Cons
- Heavy for an electric at 36.8 lb
- Rated flow only 1.1 GPM
- Bulky to store

2. Westinghouse WPX3400 Gas Pressure Washer — Best for large driveways
A 3,400 PSI, 2.6 GPM gas washer with a 212cc OHV engine, half-gallon soap tank, 25 ft hose and five nozzles.
Check price on AmazonWhy we like it
- Highest PSI of any washer on the shelf at 3,400
- 2.6 GPM rinses large slabs faster
- No cord, so it reaches far corners of a lot
- Engine oil and tools included
| Specification | Details |
|---|---|
| Engine | 212cc four-stroke OHV, recoil start |
| Pressure and flow | 3,400 PSI, 2.6 GPM |
| Tanks | 1 gallon fuel, half-gallon soap |
| Nozzles | 0, 15, 25, 40 degree and soap |
| Hose | 25 ft, M22 accessory compatible |
| Weight and warranty | About 63 lb; 3-year limited |
Westinghouse WPX3400 — 212cc gas, 3,400 PSI, 2.6 GPM, 25 ft hose, 5 nozzles, about 63 lb
The only gas-powered washer on the shelf
Every other listing here is a corded electric or a battery unit. The WPX3400 is the only gas model, and it pairs the highest stated pressure (3,400 PSI) with a 2.6 GPM pump. Cleaning speed depends on both numbers, so on a long concrete driveway or a large flagstone terrace it will move faster than any electric pick, especially with an M22 surface cleaner attached.
That power comes with responsibilities. A gas engine produces carbon monoxide, and OSHA’s carbon monoxide fact sheet advises against running gasoline-powered engines or tools in poorly ventilated areas. Run it outdoors, well away from garage doors, windows and vents, never inside a garage or shed even with the door open.
At around 63 pounds, it is the heaviest unit on the shelf, and it needs fuel and oil upkeep. For a small patio, the extra pressure is more risk than help on soft pavers.
Pros
- Most pressure and flow on the shelf
- No cord limits
- Includes a 40-degree nozzle for gentle rinsing
Cons
- Carbon monoxide: outdoor use only
- Heavy at about 63 lb
- Fuel and engine maintenance
- Easy to over-blast soft surfaces

3. Westinghouse ePX3500 Electric Pressure Washer — Best compact with soap tank
A 19 lb electric washer with 2,500 max PSI, a 20 oz soap tank, 25 ft braided hose and five quick-connect nozzles.
Check price on AmazonWhy we like it
- Most pressure of any unit under 20 pounds
- Four-wheel, low center of gravity anti-tip base
- Onboard 20-ounce soap tank
- Extendable 17.5-inch steel wand
| Specification | Details |
|---|---|
| Pressure | 2,500 max PSI, 2,000 rated PSI |
| Flow | 1.76 max GPM, 1.2 rated GPM |
| Hose | 25 ft nylon braided, easy-coil |
| Nozzles | 0, 15, 25 degree, turbo and soap |
| Size and weight | 16.5 in tall, 19 lb |
| Warranty | 3-year limited |
Westinghouse ePX3500 — 2,500 max / 2,000 rated PSI, 1.2 rated GPM, 25 ft hose, 20 oz soap tank, 19 lb
The highest pressure in a sub-20-pound washer
Seven corded washers on the shelf state a weight under 20 pounds. Among them, the ePX3500’s 2,500 max PSI and 2,000 rated PSI are the highest. The near-identical ePX3100 offers 2,300 max PSI in the same body, and the other compact Westinghouse models top out at 2,100.
The listing describes four quick-lock wheels with 360-degree steering and a low center of gravity to stop tipping when you tug the hose, a real annoyance with tall, narrow washers. Soap goes in a 20-ounce onboard tank rather than a separate foam bottle, and the pump stops when you release the trigger.
The listing does not mention M22 accessory compatibility or the cord length and type, so check those before you buy a surface cleaner for it.
Pros
- Strong for its size
- Stable, low anti-tip base
- Onboard soap tank
Cons
- Cord length not stated
- No M22 compatibility mentioned
- Small soap tank for big jobs

4. Westinghouse ePX3050 Electric Pressure Washer — Best light unit for add-ons
A 17 lb electric washer with 2,100 max PSI, foam cannon, 20 ft hose, 35 ft GFCI cord and M22 accessory fittings.
Check price on AmazonWhy we like it
- M22 fittings for surface cleaners in a 17 lb unit
- 35-foot GFCI cord
- Foam cannon in the box
- Upright 26-inch body on never-flat wheels
| Specification | Details |
|---|---|
| Pressure | 2,100 max PSI, 1,800 rated PSI |
| Flow | 1.76 max GPM, 1.2 rated GPM |
| Hose and cord | 20 ft super-flex hose, 35 ft GFCI cord |
| Nozzles | 15 and 25 degree, turbo, plus foam cannon |
| Weight | 17 lb |
| Warranty | 3-year limited |
Westinghouse ePX3050 — 2,100 max / 1,800 rated PSI, 1.2 rated GPM, 20 ft hose, 35 ft GFCI cord, 17 lb
The lightest washer that lists M22 accessory compatibility
Three listings on the shelf mention M22 fittings, the common thread for surface cleaners and undercarriage tools: the WPX3000e at 36.8 pounds, the gas WPX3400 at about 63 pounds and this ePX3050 at 17 pounds. If you want to add a surface cleaner for a small to medium patio without hauling a heavy machine, it is the most portable of the three.
Check the surface cleaner’s minimum requirements before you buy one. A 14-inch surface cleaner listing on the shelf asks for at least 2,000 PSI and 1.8 GPM, more than this unit’s rated output, so pick a smaller cleaner rated for light electric washers.
The ePX3050 omits a 0-degree nozzle, which is no loss on patios, where a pinpoint stream does more harm than good.
Pros
- Light with M22 fittings
- GFCI cord stated
- Foam cannon included
Cons
- Rated PSI too low for some surface cleaners
- Shorter 20 ft hose
- No onboard soap tank

5. Westinghouse ePX3100s Electric Pressure Washer — Best for small patios and balconies
An ultra-compact 2,100 max PSI electric washer with a foam cannon, 20 ft hose, 35 ft GFCI cord and onboard holders.
Check price on AmazonWhy we like it
- Lightest corded washer on the shelf
- Built-in holders keep gun, lance and nozzles together
- 35-foot GFCI cord for reach

| Flow | 1.76 max GPM, 1.2 rated GPM |
| Hose and cord | 20 ft high-pressure hose, 35 ft GFCI cord |
| Weight | Listed at 10 lb in bullets, 13.5 lb in specs |
| Warranty | 2-year limited |
Westinghouse ePX3100s — 2,100 max / 1,800 rated PSI, 20 ft hose, 35 ft GFCI cord, about 10 to 13.5 lb
The lightest corded electric washer among the listings
The ePX3100s is the smallest corded machine on the shelf. Its bullets describe a 10-pound unit and the spec field lists 13.5 pounds; either way it is lighter than every other corded model, which start at 16.6 pounds. That makes it easy to carry up steps to a deck, balcony or rooftop patio.
It shares the 2,100 max PSI and 1.2 rated GPM of the ePX3050 and ePX3100v, enough for patio furniture, planters, decks and lightly soiled concrete. It does not mention M22 fittings, so plan on wand work rather than a surface cleaner.
One difference worth noting: its warranty is 2 years, while every other Westinghouse washer on the shelf states 3 years.
Pros
- Very light and compact
- Long GFCI cord
- Tidy onboard storage
Cons
- Shorter warranty than siblings
- Conflicting weight figures
- No surface cleaner fittings mentioned

6. LEOTER Cordless Pressure Washer — Best cordless for patio furniture
A cordless 1,250 PSI washer with a brushless motor, two 21V 4.5Ah batteries, a 6-in-1 nozzle and a 28 ft intake hose.

| Accessories | 6-in-1 nozzle, foam cannon, 28 ft hose, filter |
| Flow (GPM) | Not stated in listing |
LEOTER DJ-810 — cordless, 1,250 PSI, 300W brushless, two 21V 4.5Ah batteries, 70 to 110 min runtime
The longest stated runtime among six cordless washers
Six cordless washers came up in our searches. Their runtime claims range from 20 to 45 minutes for the Blissthrill units, about 40 minutes for MIMYTH and 60 minutes for Teodute, to 70 minutes on high and 110 minutes on low for the LEOTER, which ships with two 4.5Ah batteries. It is also the only cordless listing that describes automatic shutoff after 45 seconds idle plus overheat and pressure protection.
Be realistic about what a battery washer does. At 1,250 PSI and no stated flow, it suits patio furniture, planters, grills, bikes and spot-cleaning pavers, not stripping algae off a whole slab. Its advantage is that it can draw water from a bucket or rain barrel where there is no spigot.
Pros
- No cord or spigot needed
- Two batteries for long sessions
- Built-in protection features
Cons
- Far less pressure than corded units
- No flow rate stated
- Not for whole-patio deep cleaning

How to choose a pressure washer for patios
Electric, gas or cordless
Corded electric washers are the default for patios: they start instantly, need no fuel or oil, run quieter and weigh 13 to 37 pounds on this shelf. Gas earns its place on long driveways, large terraces and oil-stained concrete, where higher flow speeds up rinsing, but it brings weight, noise, engine upkeep and exhaust. Battery washers are a different category: lower pressure, but no cord and no spigot needed, so they suit balconies, rooftop patios, outdoor furniture and quick touch-ups between deep cleans. Many homeowners pair a corded unit for the annual clean with a small cordless one for rinsing chairs and planters.
PSI, GPM and why both matter
PSI is how hard the water hits; GPM is how much water carries the dirt away. Listings often quote a maximum PSI at a low flow and a lower “rated” PSI at working flow. Compare rated numbers. For a typical concrete patio, roughly 1,800 to 2,600 rated PSI with about 1.2 GPM is plenty; large driveways and oil stains reward gas-level pressure and flow.
Match pressure and nozzle to the surface
Start with the widest nozzle, usually 25 or 40 degrees, and test a hidden corner. Keep the tip 8 to 12 inches from the surface and work with the grain on wood. Soft sandstone, older concrete and stamped finishes etch easily, and paver joints lose sand quickly; re-sand and consider sealing afterward. Skip the 0-degree nozzle on patios entirely. If moss is the problem, our guide to removing moss from a patio covers gentler options, and our driveway sealer picks help protect clean concrete.
Surface cleaners save time on flat ground
A spinning surface cleaner hovers over the slab and leaves even, stripe-free results. Check that your washer accepts the attachment (M22 or quarter-inch quick connect) and that its rated PSI and GPM meet the cleaner’s minimums.
Safety notes
Electrical protection. The CPSC has warned consumers to stop using several pressure washers sold online because they lack a ground-fault circuit-interrupter (GFCI) on or near the plug and an adequate-length cord, creating a risk of electrocution and shock. Choose a washer whose listing states a GFCI cord, plug only into outdoor GFCI outlets and avoid extension cords where possible. Of the corded picks here, the WPX3000e, ePX3050 and ePX3100s listings state a GFCI cord; the ePX3500 listing does not mention one, so confirm on the unit.
Carbon monoxide. OSHA warns that internal combustion engines are a common source of carbon monoxide and advises against using gasoline-powered engines or tools in poorly ventilated areas. Run gas washers outdoors only, away from doors, windows and air intakes.
Injection injuries. A pressure washer stream can cut skin. Never point the wand at people, pets or your own feet, wear closed shoes and eye protection, and engage the trigger lock when you set the gun down.
Runoff and detergents
The University of North Carolina’s environmental health and safety guidance recommends sweeping first, testing plain water before reaching for chemicals and keeping soapy wash water out of storm drains, which flow untreated to streams. On a home patio, direct rinse water onto lawn or garden beds rather than the street, and use cleaners labeled for the surface.
When to hire a pro
Large stamped or exposed-aggregate driveways, delicate natural stone, second-story decks and jobs that end in resealing are often worth handing to a pro. Our landscaping services page can connect you with local crews.

Frequently asked questions
How much PSI is needed to clean a concrete patio?
Around 1,800 to 2,600 rated PSI handles most dirt and algae on concrete. Oil stains and very large slabs go faster with higher pressure and flow, such as a gas washer, plus a surface cleaner and a degreaser.
Can a pressure washer damage pavers?
Yes, if the nozzle is too narrow or too close. Use a 25 or 40-degree tip, keep 8 to 12 inches away and test a hidden spot first. Expect to re-sand joints after cleaning.
Is an electric pressure washer enough for a driveway?
For most residential driveways, a 2,000-plus PSI electric with a compatible surface cleaner works well. Gas makes sense for very large areas, heavy staining or when speed matters most.
Is it safe to run a gas pressure washer in the garage?
No. Gas engines produce carbon monoxide, and OSHA advises against using gasoline-powered tools in poorly ventilated areas. Run them outdoors, away from doors, windows and vents.
How often should a patio be pressure washed?
Once a year, usually in spring, is enough for most patios. Shaded, damp areas that grow moss or algae may need a second, gentler cleaning in fall.
