If an electric power washer isn’t powerful enough for the job at hand, and you’re looking for a gas-powered power washer with a little more “umph”, a 3100 psi power washer is a good place to start looking. Models like the Simpson or Generac pressure washer below are perfect for tougher washing jobs, like removing tough moss and grime, or covering a larger area like a driveway. Gas-powered pressure washers really offer a more reliable option, and should give you a much longer lifespan than their electric counterparts. Need even more power? If 3100 PSI power washers aren’t quite enough, consider looking at the commercial pressure washer list.

1. Simpson (Honda) 3100 Pressure Washer

The Simpson pressure washer comes in at the top of the list, due to it’s dependable Honda engine and welded steel frame. This is a near bulletproof model, and comes complete with a 2 year warranty. Simpson provides five different nozzle tips (0°, 15°, 25°, and 40°), so you can quickly change the nozzle to match the level of cleaning needed.

Honda 3100 psi pressure washers give a level of power that’s optimal for tough jobs, like cleaning concrete pathways that have built-up stains. With a quality engine and pump, this pressure washer will serve you well for years to come.

2. Generac 3100 Pressure Washer

Generac power washers is built for tougher jobs, and in a pinch, can function as a commercial pressure washer. Just like the Simspon at the top of the list, it will use it’s 3100 PSI and 2.4 gallon-per-minute flow to really get dirt, graffiti, and grime out of sight. Unlike the Simpson, this includes an on-board detergent tank, which is a nice to have feature.

All of the controls (choke, on/off switch, etc) are higher off the ground, saving you from busting your back when crouching over. 4 nozzle attachments are included, and the pressure washer hose itself will hold up to any abuse you throw at it (however, some have mentioned that the hose thickness may make it hard to maneuver in tight spaces).

Pressure Level: 3100 PSI
Flow Rate: 2.4 GPM
Weight: 57 lbs
Price: $390 – 400
Key Feature
• Good ergonomics

4. Excell 3100 PSI Pressure Washer

Similar in size and layout as the Simpson pressure washer above (#1), this Excell model offers a slightly higher GPM flow rate, and yet an even lower price tag to the Simpson. However, with that lower price tag comes a potentially less-reliable engine (212cc OHV gas engine). It still features an axial style brass head pump, and 5 quick-change nozzle tips.

If you’re on a budget and only see yourself needing a 3100 PSI pressure washer once a year, this might be a great option for you.
