Best Pressure Washer
15 hours ago
I’ve been through numerous pressure washers and this by far has been the best one! Easy to start, great pressure! Cleans concrete like no other! Removes paint from concrete effortlessly! The Cat pump is extremely robust and powerful! Paired with a Honda and you have yourself an excellent combo!

I bought this pressure washer a couple weeks ago and I’m super happy with it, it’s got a strong reliable engine in it, and the cat pump is excellent to work . No issues whatsoever so far I plan on taking good care of it and I don’t expect to see issues anytime soon
