Went to Aqua Blast in Decatur for a pressure washer. First model offered was a Honda powered, 4gpm, 4000psi unit. When I asked what the next step down was, the salesman offered a LIFAN 7 hp, 3gpm, 2700psi. This unit cost less, had a built in hose reel and electric start. Right away my wife liked the electric start. Any info on LIFAN? Never heard of it myself. I have used pressure washers before but never paid attention to the specs. Home use only here, siding, side-by-side, vehicles, sidewalks and patios. What gpm/psi combo do I need? Basically went here because I had heard much good about Aqua Blast from farmers/contractors and they advertise on WOWO. All input appreciated.
