Super strong pressure washer

7 days ago
I bought this pressure washer to do sidings of houses and driveways as a side job and it has exceeded all expectations. If you’re on the fence whether or not to get it, pull the trigger. You won’t regret it.

GREAT PRESSURE WASHER!!!

10 days ago
I ordered this for general use around my home including cleaning siding, concrete, my tractor and its equipment, plus getting river mold off of my boat. It does a great job. It was very easy to assemble and I had it ready in just a few minutes. Make no mistake. This washer is a brute!
