Two Critical Ratings
Although higher pressure cleans faster, don’t allow small differences in psi to drive your decision on which machine to buy based on pressure washer reviews. You probably won’t notice much difference between 2,800 and 3,000 psi, for example. The gas models we tested range from 2,500 psi to 3,100 psi; for the electric power washer reviews from 1,700 to 1,800 psi.
What They Can and Can’t Do
With accessories, you can turn your gas-powered pressure washer into a wet sandblaster or use it to power a water broom or a mechanical sweeper. Add a telescoping extension wand and gutter cleaner (such as the General Pump Giraffe) and you can clean your second-story siding and gutters without climbing a ladder.
But pressure washers are also very good at destroying items around your home. The high pressure can break windows, gouge wood siding and decking, and force water behind siding and flashing, causing extensive damage. They work great for blasting mud off your car or truck but leave a fine film of dirt behind. A regular garden hose and wash mitt actually work better for normal car washing.
