I manage a fleet of semi-trucks, and I need a quick and efficient way to wash them. It normally takes 2 hours to wash one truck with a hose, spray nozzle, and brush. I need to know if there is a portable pressure washer out there that can clean a dirty truck without the need for scrubbing with a brush. This should reduce the wash time to less than half.

There are many different models of pressure washers but without a brush you always have slight film of dirt. But if you don’t mind a slight film of dirt it would cut your wash time in half or maybe less than half. I hope this helps you out.
Excellent luck.

Basically I’m looking for how to tell a high quality pump from a terrible to average quality. Thanks. Oh and the pumps for a pressure washer…I reckon. I’m asking this for my father.

Check at www.Consumer.org.com

More than likely, you have blown an O ring in your high pressure hose at one of the couplers.

If you let go of the trigger, there should be no water coming out anywhere along the hose, or at the couplers, or the gun.

Ours has a HONDA engine.
Been very dependable and has fantastic variances in degree of pressure.

Possibly Consumer Reports has a write up and rating on Power washers. You can get a copy at the library if not available on-line.

Hi I wanna use a pressure washer to wash my car- but don’t have tap water available outside. Is it possible to use a pressure washer with a water bucket/tub instead of tap? Thanks

Karcher washers and similar types will happily work from a receptacle of water. I don’t reckon a bucket will be huge enough and you also have to avoid any particles being sucked into the pump.
Keep the supply hose small and try to supply a bit of pressure by raising the reservoir to provide a "head" of water.
