Question about water pressure washer. - PeachParts Mercedes-Benz Forum

Dear friends:

I've seen some ads for $79 water pressure washers (electrical ones-1300 psi and 1.7 gpm) and some $300 washers (based on Honda engines-2200 psi and 2.5 gpm). I have always wanted some pressure washers for cleaning up the driveway etc... but wondered whether the electrical ones are strong enough for these purposes. How much stronger is a 1300psi/1.7 gpm pressure washer compared to a regular water noozle set at the Jet position?

Thanks for your precious information.

Best regards,

Eric

Eric:

I bought a unit from Northern Tool that gives me up to 2400 psi at 3 gallons per minute. Now, that's almost enought to strip paint, but you can reduce the pressure either with the unloader valve or by throttling the engine back. I use it to pressure wash everything (except my teeth). I would suggest that you analyze how you would expect to use the unit and buy accordingly. Here in the mountains, I pressure wash my log cabin prior to oiling, ditto the decks. At my winter digs, I use it to clean the carport floor and, with reduced pressure, the slump brick outside walls.

If all I wanted it for was to clean engines and the bugs off the front of the car, I probably would have gone with one of the lesser expensive units.

Hope that helps you to decide...

The little electric ones (IMHO) aren't really any good. The pressure developed just doesn't seem to get any cleaning done. For use around the house I would stick to the Honda powered unit. I tried to use the electric type to clean my rubbish barrels with no positive results. When using the gas powered one this chore is done in minutes. My $ 0.02.
