Straight out of the gate, here’s the gas-powered OneWash model, and this pressure washer is packing a punch.

Producing 3100 PSI at 2.8 GPM, that’s a cleaning power of 8680! Now it’s called OneWash for a reason as using that much pressure on fragile items could cause damage, while you can mitigate that by choosing the appropriate nozzle, sometimes that can still be too much.

The OneWash comes with a function that allows you to change the PSI from heavy-duty power mode to a nice delicate low to medium duty mode at 2000 PSI.

This system is called the “PowerDial” and it allows you to adjust the pressure to exactly the job at hand.

With it’s cleaning power of 8680 you can easily do medium and even heavy-duty cleaning tasks, the 212cc OHV engine doesn’t bat an eyelid in generating the high pressures you need to wash dried in oil stains in concrete.

This pressure washer is a cold water only pressure washer.

With powerful pressure washers comes… a great amount of weight, this is not a light unit, the Generac OneWash weighs in at 68.6 pounds. Thankfully it’s large 11-inch wheels make this heavy machine easily transportable.

Add to that it’s 30 foot-long high -pressure hose, and well, you won’t have a problem reaching anywhere in your yard with very little need to keep moving the main unit.

Onboard the OneWash, you get a ½ gallon detergent tank, which is quite large, so you shouldn’t need to refill often. You also get 3 quick-change nozzle tips: 0-degree, 25-degree, and soap dispenser.

Perhaps the first Generac pressure washer on this list is a touch too powerful for your needs. Well, this is where the Generac 6922 comes in. It’s slightly less powerful, and this been designed to be ergonomically superior. Asides from the lower cleaning power, what really separates this model from the previous on is it’s cushion grip handle.

This really improves the comfort of lugging a pressure washer around, at to that that on a cold day, you don’t want to be holding on to a freezing cold metal bar. The cushion grip saves you from that.

 The 6922 is powered by a 196cc Generac OHV engine, which produces 2800 PSI at 2.4GPM, which gives us a cleaning power of 6720.

This model has a slightly less robust design compared to the 6602 OneWash, but it is much more convenient for storing. The 10-inch never-flat wheels combined with the cushion grip handle really gives you the mobility you may be looking for.

This is a model that stands firm from the Generac pressure washer family, Like the 6602 OneWash, you get the “PowerDial” to allow you to change the water pressure output, to make your life easier, rather than being on the pressure washer unit, with this model its on the spray gun itself. Allowing you to quickly adjust the power being produced.

First, you get the “PowerBroom,” which with the aid of the high-pressure water stream, makes short work of brush/broom work. It focuses the cleaning into a single area and can clean concrete and other surfaces 4 times faster than using the lance alone.

You a TurboNozzle with creates a pinpoint system to help blast away even the most stubborn stains. Finally, you get the SoapBlaster attachment with provides an additional soap spraying option for deeper cleaning, this attachment allows you to increase your soap spraying distance 3x.

If the above wasn’t enough, the 7122 SpeedWash also comes with never-flat wheels and 4 angled quick-connect nozzles, a 30 foot-long high-pressure flex hose that’s kink and marring resistant.

The pressure produces by this unit is enough to prepare surfaces for paint jobs, stripping away the previous layers of paint. You can wash a concrete driveway, house siding and much more.

Personally, I love this machine.
