Is the pump worth the $$ for residential use
I'm comparing Model# 1578173 to Model# 1578112.. The only real difference I see is the pump. For a residential user who will use the pressure washer heavily for short periods of time (like all weekend twice a year), is the pump that much better for the $150...
