If our electric power washer reviews leave you wanting more power, then models like the Simpson or Generac pressure washer below are perfect for those tougher cleaning jobs, like removing graffiti, stripping paint, or covering a larger area like a driveway. Gas-powered pressure washers really step the game up (in both flow rate and PSI), and should give you a much longer lifespan than their electric counterparts. Need even more power? If a 3100 PSI pressure washer isn’t quite enough, consider looking at the commercial pressure washer list.

1. SIMPSON MSH3125-S Pressure Washer

At 3100 PSI and 2.5 gallons per minute, the Simpson pressure washer comes in at the top of the list. With a dependable Honda engine and welded steel frame, this is a near bulletproof model, and backed by a 2 year warranty. Others on the list come with pressure washer nozzles, but the Simpson comes with five different nozzle tips (0°, 15°, 25°, and 40°), so you can change the angle with ease to match the job at hand.

If pressure washing concrete stains or heavy grime is something you face multiple times a year, use a pressure washer that will complete the job quickly and efficiently, so you can spend your time doing something more…exciting. While this may not be a cheap power washer, the price is a bargain for what you’re getting – a commercial-grade gas powerwasher in a compact, maneuverable package.

Details

Pressure Level: 3100 PSI

• Heavy-duty, abrasion-resistant hose
• Multi-year warranty
Best Suited for:
• Medium/heavy-duty residential use
• Light/medium professional use


2. Generac 7019 OneWash 3

Now, back to the gas. This Generac power washer is built for tougher, longer jobs, and can even function as a commercial pressure washer if needed. Just like the Simspon at the top of the list, its in the heavier-duty 3000 PSI pressure washer category, with a high flow rate to really get dirt, graffiti, and grime out of sight. Unlike the Simpson, this does include an on-board detergent tank, which is appreciated, and all of the controls (choke, on/off switch, etc) are higher off the ground, saving you from crouching.

4 nozzle attachments are included to easily change the power and angle of the spray, and the heavy duty pressure washer hose will hold up to any abuse you throw at it (however, some have mentioned that it’s thickness may make it hard to maneuver in tight spaces).

Details
Type: Gas
Pressure Level: 3100 PSI
Flow Rate: 2.4 GPM
Weight: 57 lbs
Price: $390 – 400
Key Feature
• Good ergonomics
• Accessible controls
• On board detergent tank
Best Suited for:
• Medium/heavy-duty residential use
• Light/medium professional use
• Maneuverability


3. Briggs & Stratton Pressure Washer

Another gas power washer makes the list with the Briggs and Stratton pressure washer, which means reliability (but also increased size and noise). While it may not be the most powerful gas washer on the list at just 2200 PSI, the maintenance-free pump and Easy-Start 4-stroke engine make this a great choice if you have consistent medium-duty cleaning needs like wood siding, decks, or light concrete work. It has three spray tips (0º, 25º and Soap) and features a detergent injection system that mixes detergent directly into the pressurizes water stream, helping to preserve your high pressure hose.

On the topic of the power washer hose, we like the small detail that the hose storage is beneath the handle of the washer, as opposed to the side (like the Simpson) – it makes for tidier storage. Overall, Briggs/Stratton makes rock-solid engines, and the one on this pressure washer is no exception.

Details
Type: Gas
Pressure Level: 2200 PSI
Flow Rate: 1.9 GMP
Weight: 50 lbs.
Price: $260 – $270
Key Feature
• Dependable 4-stroke engine
• Detergent injection system
Best Suited for:
• Consistent medium-duty jobs


4. Yamaha 3000 Pressure Washer

This Yamaha power washer has a slightly higher GPM at 2.8, meaning it moves water faster than others on the list. This is going to cut the time it takes to remove moss, scum, and dirt significantly. Unlike others on the list, this gas-powered pressure washer has an all-in-one, multi-level spray nozzle, meaning you won’t have to worry about losing separate tips and can change your rate and angle of spray in seconds.

The Yamaha engine (backed by a great warranty and customer service) starts with ease every time, and runs considerably quiet, which is a major plus for a residential neighborhood. The layout/design is what we like the most, with big ol tires to roll over rough terrain, and an easily accessible hookup point and detergent tank.

Details
Type: Gas
Pressure Level: 3000 PSI
Flow Rate: 2.8GPM
Weight: 96lbs
Price: $770 – 780
Key Feature
• All-in-one nozzle
