helpBoxPressure Washer Hose Length
All pressure washers require a hose to operate the unit by spraying water. Many of the units featured here come with a hose, or you can also find a separate hose. A longer hose will mean more mobility and a larger operating area around the pressure washer.

helpBoxPressure Washer Power Source
Gas powered pressure washers are conveniently portable and typically more powerful than electric pressure washers. They are great for outdoor and industrial work, but make sure you don't use them inside because the engines produce carbon monoxide. Electric pressure washers can be used both inside and outside, though they are bound by a power cord and may have less power. However, they are still effecitve and make less noise than gas powered pressure washers

Great pressure washer
By Jay G. from Long Grove, IL on Jun 02, 2014
I have used/owned many different pressure washers and this is by far the best I have owned. Engine easily starts on first or second pull and the amount of pressure is awesome, it will literally push you back unless you lean into it a little. My old pressure washer is a toy compared to this one.
