3000 PSI Pressure Washer Reviews

Karcher , Generac, Dewalt

3000 PSI pressure washer machines are generally considered medium to heavy duty washers. They are in most cases powered by gasoline. Gas powered washers of a heavy duty category produce a lot of noise and as a result are less used at home for day to day cleaning purposes. This is part from the problem of harmful fumes produced by the machines.

The best gasoline pressure washer is one powered by a Honda engine. These are quick and much easy to start often starting at first pull. Honda engines also last longer. The best combination of engine and pump involves a Honda engine and a CAT pump. Seasoned owners of pressure washers call this combo a winning team.

The following are reviews of selected 3000 psi pressure washer models available on the market. We sought to review only those washers considered best pressure washers even though they might have some short comings as revealed in PROS and CONS of each.
