Our acreage picks
Simpson Cleaning 3400 PSI Gas Pressure Washer, 2.5 GPM, Honda GX200 Engine
Gas pressure washer with a Honda GX200 engine, a CAT triplex pump, 3400 PSI at 2.5 GPM, a 25-foot hose and 5 nozzle tips.
Read the full review
The title and bullets describe a contractor machine: a Honda GX200 engine, a CAT triplex pump delivering 3400 PSI at 2.5 GPM, and a 25-foot Monster hose with 5 nozzle tips. The bullets name deck cleaning and wood restoration, and the aluminum platform with 10-inch tires suits uneven ground.
Trust the title and bullets over the spec table: it lists 3100 PSI, 2.3 GPM, a CRX engine, a 50-inch hose, and Residential Use, against the commercial wording of the title and bullets. The components line also mentions 3200 PSI and 2.8 GPM. Those contradictions cost marks, but the quoted warranty terms keep it first.
Pros
- 3400 PSI at 2.5 GPM, with a Honda GX200 engine
- CAT Industrial triplex plunger pump with thermal relief protection
- 10-inch premium pneumatic tires for uneven ground, per the bullets
- 25-foot Monster hose plus 5 quick-connect nozzle tips and a spray gun with safety lock-out
Cons
- Spec table contradicts the title: 3100 PSI, 2.3 GPM and a CRX engine
- Spec table also lists a 50-inch hose length against the 25-foot hose in the bullets
- 73 pounds to move and store
- 2.5-gallon tank for a gas machine aimed at commercial work
IvyBess 4200 PSI Gas Pressure Washer, 4.0 GPM, 212CC Engine
Gas pressure washer with a 212CC engine, 4200 PSI at 4.0 GPM, a 25-foot hose and 5 nozzles.
Read the full review
The listing states 4200 PSI at 4.0 GPM from a 212CC 7HP engine with an axial cam pump, plus a 25-foot hose, 5 nozzles and a 3.6-liter fuel tank. The bullets name fence and driveway maintenance, vehicle cleaning and post-storm cleanup, and the steel frame and 10-inch wheels suit rough ground.
Read the maker claims with care: the bullets claim stronger cleaning than ordinary 3200 PSI models without naming them, so the comparison cannot be checked. The bullets also note a warranty term and usage tips, but the warranty term as written is vague, so no warranty score is given.
Pros
- 4200 PSI at 4.0 GPM for heavy grime work
- 212CC 7HP 4-stroke OHV engine with an axial cam pump
- 25-foot hose, 5 quick-connect nozzles and a 3.6-liter fuel tank
- 10-inch pneumatic wheels and a steel frame with an anti-rust coating
Cons
- Bullets compare it with ordinary 3200 PSI models without naming them
- 66 pounds to move around a site
- Gas engine means outdoor use only and fuel handling on every job
- Soap tank and fuel tank figures sit close together, so check the caps
Simpson PowerShot PS60843 4400 PSI 4.0 GPM Gas Pressure Washer
Professional-style gas washer with a 420cc CRX engine, a triplex pump, a 50 foot hose and 13 inch tires.
Who it's for: owners with a lot of equipment to rinse who want the highest flow.
Who should skip it: anyone who wants a light unit, or lives in California.
Read the full review
The PS60843 pairs a CRX 420cc engine with an AAA industrial triplex plunger pump, delivering 4400 PSI at 4.0 GPM with thermal relief to prevent overheating. The listing includes a 50 ft hose, five quick-connect nozzles, a 31 in steel wand and 13 in pneumatic tires on a welded steel frame. It is 49-state compliant and not shipped to California. The listing does not state a warranty term.
Pros
- Highest pressure and flow here, 4400 PSI at 4.0 GPM
- AAA triplex plunger pump with thermal relief
- 50 ft kink-resistant hose
- 13 in pneumatic tires and a welded steel frame
Cons
- No warranty term is stated on the listing
- Not sold to California
- Heavy: 61.23 kg in the specs table
- No UL, ETL or CSA listing is stated
Westinghouse WPX3000e Electric Pressure Washer, 3000 Max PSI, 1.76 Max GPM
Electric pressure washer with an induction motor, 3000 max PSI, 1.76 max GPM, onboard soap tank and a 35 foot GFCI cord.
Who it's for: owners who want electric convenience without gas engine upkeep for siding, decks and cars.
Who should skip it: anyone needing continuous triplex pump durability or over 2 GPM flow.
Read the full review
The Westinghouse WPX3000e uses an AC 120V induction motor, delivering 3000 max PSI and 1.76 max GPM (2600 rated PSI, 1.1 rated GPM). It features an axial 3-piston pump, steel cart frame, 10 inch never-flat wheels, 0.45 gallon soap tank, 25 foot hose, 35 foot GFCI cord and five nozzles (0, 15, 25 degrees, soap, turbo). Weight is 36.8 pounds. Warranty is 3 years limited.
Pros
- Stated 3000 max PSI and 1.76 max GPM from an AC 120V induction motor
- 35 foot power cord with GFCI and auto-stop pump
- Rugged steel cart frame with 10 inch never-flat wheels
- Stated 3-year limited warranty covering service, labor and parts
Cons
- Continuous rated pressure drops to 2600 PSI and 1.1 GPM per the listing
- Axial 3-piston pump rather than a commercial triplex plunger pump
- 25 foot hose is shorter than the gas models in this comparison
- Requires a dedicated 120V outlet capable of supporting electric pressure washing
LWQ S5 Portable Pressure Washer, 2030 PSI, 2.5 GPM
Lightweight 16.6-pound electric pressure washer offering 2030 PSI, 2.5 GPM water flow, 4 spray nozzles, and an included foam cannon.
Who it's for: property owners who need a compact, ultra-lightweight power washer for vehicles, patio furniture, and small decks.
Who should skip it: anyone needing heavy gas cleaning power or seeking formal safety certifications and warranty coverage.
Read the full review
The LWQ S5 is a compact electric pressure washer rated at 2030 PSI and up to 2.5 GPM. It rolls on 2 wheels, features an anti-tipping base, and weighs 16.6 pounds with dimensions of 18 by 14 by 11 inches. Included accessories consist of a 6.3 meter hose, 4 quick-connect nozzles (0°, 15°, 25°, and 40°), and a foam cannon. The listing contains an error in its spec table, stating tank volume as 2.5 gallons despite the machine lacking an onboard water reservoir. The listing states that some industry standards are met but names no specific safety certification or regulatory standard, and no warranty term is stated.
Pros
- Lightweight build at only 16.6 pounds for easy carrying and pantry storage
- Dual-roller design with anti-tipping base stabilizes the unit during use
- Can draw water from either a pressurized faucet or a standing bucket
- Includes 4 quick-connect nozzles and an external foam cannon bottle
Cons
- No warranty term is stated on the listing
- Spec table lists tank volume as 2.5 gallons, apparently confusing detergent capacity with the 2.5 GPM flow rate
- Listing only notes vague compliance with some industry standards without naming specific certifications
- Electric corded operation requires proximity to an electrical outlet

Buying guide: best pressure washer for commercial use
Gas or electric for commercial work
Gas listings dominate this guide: the Simpson, PowerShot and IvyBess listings are gas powered, while the Westinghouse listing is electric. Gas suits sites without power access, while electric suits sites where power is close at hand. The LWQ listing does not state a power source in its title, so treat its power type as not stated.
Pressure and flow: what the listings state
Pressure and flow decide how fast grime comes off a surface. The titles here list 2030 PSI, 3000 PSI, 3400 PSI, 4200 PSI and 4400 PSI, with flows of 1.76 GPM, 2.5 GPM and 4.0 GPM. Higher pressure suits stubborn grime on concrete, while higher flow rinses a wide area faster. Match pressure and flow to the surface: a lower-pressure pick suits lighter washing, and the higher-pressure gas picks suit driveways, fences and equipment.
Hoses, nozzles and reach
Hose length decides how far the machine reaches without moving it. The Simpson ALH3228-S and IvyBess listings state a 25-foot hose, while the PowerShot listing states a 50-foot hose. The Simpson listings state 5 quick-connect tips, and the IvyBess listing states 5 quick-connect nozzles. The Westinghouse and LWQ titles state no hose or nozzle details, so confirm those parts before buying.
Frames, wheels and storage
Frames and wheels decide how the machine moves around a site. The PowerShot listing states a welded steel frame with 13-inch pneumatic tires, the IvyBess listing states a steel frame with an anti-rust coating and 10-inch pneumatic wheels, and the Simpson ALH3228-S listing states an aluminum platform with 10-inch pneumatic tires. Weight matters too: the Simpson ALH3228-S listing states 73 pounds and the IvyBess listing states 66 pounds, while the other listings state no weight.
Safety on the job
Pressure washers demand respect on every job. Never aim the spray at people or animals, and run gas units outdoors only. The Simpson ALH3228-S listing states a spray gun with a safety lock-out. Keep children and pets out of the work area, and check the maker manual before starting a new surface.
Never point the spray at people, animals or yourself: the stream can cut skin. Run gas pressure washers outdoors only, far from doors, windows and vents, because engine exhaust carries carbon monoxide. Start with the widest nozzle and keep electric units on a GFCI outlet. Refuel only with the engine off and cool. See CPSC carbon monoxide guidance. Read our Safety Disclaimer.
Matching It to Your Property
- For rough ground, the PowerShot listing states 13-inch pneumatic tires and the IvyBess listing states 10-inch pneumatic wheels on a steel frame.
- For work around obstacles, the PowerShot listing states a 50-foot hose, while the other gas listings state a 25-foot hose.
- For storage, the IvyBess listing states storage hooks for the spray gun and hose.
- For sites with power close at hand, the Westinghouse listing is the electric pick at 3000 PSI and 1.76 GPM.
The Acre Score explained
The Acre Score weighs performance, build and value most, with safety where it applies, and warranty where a concrete term is stated. How we pick explains the weights.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Simpson ALH3228-S | 9.7 | 29 | 21 | 20 | n/a | 4 |
| IvyBess 4200 PSI | 9.7 | 32 | 21 | 21 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
FAQ: mowing large lots
What are pressure washers good for?
Pressure washers wash driveways, decks, siding, fences, vehicles and yard equipment. The listings here name deck cleaning, fence and driveway maintenance, vehicle cleaning and exterior house renovation as typical jobs. Match pressure and flow to the surface: a strong spray suits concrete, a gentler spray suits painted surfaces and windows.
How much psi is a pressure washer?
It depends on the model. The titles in this guide list 2030 PSI, 3000 PSI, 3400 PSI, 4200 PSI and 4400 PSI. Lower-pressure picks suit lighter washing, while higher-pressure picks suit stubborn grime on driveways and equipment. The listing title is the reliable figure here, since one listing here states a different pressure in its spec table than in its title and bullets.
What are the best commercial pressure washers?
The picks here cover gas and electric models for commercial work. The Simpson ALH3228-S listing pairs 3400 PSI at 2.5 GPM with warranty terms quoted separately for engine, pump and frame. The PowerShot listing offers 4400 PSI at 4.0 GPM with a 50-foot hose. The IvyBess listing offers 4200 PSI at 4.0 GPM with a 25-foot hose. The Westinghouse and LWQ titles list less detail, so weigh their lower stated pressure against the fuller listings.
How to fix a pressure washer?
Start with the simple checks the listings name: a blocked nozzle, a loose hose connection, and the water supply. The IvyBess listing also names checking the oil level indicator and fitting the rubber gasket tightly at the water pipe connection. For anything beyond those checks, follow the maker manual rather than opening the engine or pump.
