Powerful pressure washer

8 days ago
The pressure washer is has more power than anything I need it for, and I can adjust the pressure down for a gentler spray. I upgraded from a 3300 psi and am happy with the bigger machine.

Very powerful

9 days ago
This washer is very powerful so be careful. Just remember that if it doesn't start on the second pull you'll feel it get harder to pull, pull the trigger and release the pressure. So far love it.
