short answer yes
long answer
I bought the first prowler which was a 12hp kohler over 5 years ago to back up my less than a year old ACE 310 machine as it just wasn't reliable
I used to put it in the back of the LWB sprinter I had so I could "dual wand" using two machines of one tank of water. Or just as a back up on long travel jobs
After 2 months I took out the 310 and put the prowler in full time, sold the 310 and bought another prowler, someone once said "it's a honda pressure washer with heat and a suck, a fair description as they are simple to use and work on have very few thing that go wrong, My 10 year old honda pressure washer is still doing the do.
Any one with a little mechanical knowledge could sort any problems, and if you haven't got the skills, take it to a lawn mower or pressure washer workshop as they will recognize everything.
Yes it has a small engine and a small blower but the blower is fettled somehow to spin very fast and generates a lot of heat that vaporizes the water to steam, Because there is no waste tank the vac is very good and the 2000psi pump is more than some of the bigger machine have.
If you want a comparison It's a entry level skoda fabia/ renault twingo / smart car, there bigger cars out there that do the job, faster, smoother, hotter,harder,longer, flashier, sexier and many more things ending in er. But personally I like the it gets job done.
It' not the greatest looker " but you don't look at the mantelpiece when your stoking the fire"
