Question about water pressure washers.

[ericnguyen]

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
