I have a 3200 psi gas pressure washer and the inside spinning brush barley moved. When I looked at it I saw the gearing ratio used was all wrong. What good is a rotating spin brush if it barely spins and slows down the water pressure?
Get gas for your pressure washer. Drag out your pressure washer , Hook up your water hoses, make sure they got gaskets, hook up your pressure hose and brush head. Drag water hoses and pressure hoses around your car. Fight the floppy brush head. Fight the brush with no angle. uses lots of soap. Rinse off your soap with another hose or disconnect brush and rinse off your ( soap dries fast on a hot day) you're finished disconnect and roll up all two sets of hoses. Drager pressure washer back into storage. VS a bucket and a brush
