I am looking for assistance in determing what size pressure washer is needed for 'general' household use (i.e. cleaning siding, decks, sidewalks)

Thanks

I have a Water Blaster, model#2SF30G.  1200 PSI, 3450 RPM,  3GPM with a 5 horse Briggs and Stratten for power.  Built on a two wheel cart with hoses long enough to reach form the ground to the roof.  This will handle everything from washing the car to hosing down the driveway and pressure washing the roof.   They have a toll free number 1-800-622-2160 or contact them at, Water Blaster, PO# 428, Decatur Ar. 72722
