We've had a Prowler 313 (2000psi) for two years now and I wouldn't be without it. Got a job to do with it tomorrow (Sunday), two of us are doing it mainly to take turns on the wand and alleviate cramps from squeezing the trigger, job is priced at £1000 +vat.
We're starting at 8am and should hopefully be finished and back at home for roast beef dinner by 1:30pm. The machine is all prepped and ready to go, only time the machine should stop is when it needs the filter cleaned or refuelled.
As a concession we'll be running it directly from an outside tap, waste is getting fed directly into a surface drain.
Of course there are bigger and more powerful machines out there by different manufacturers, there's even a couple of bigger Prowlers, namely the Scirroco and the Inferno. However what I like about the Prowler is the ease of operation, the fact that theres no waste water and it can be lifted in and out of the van easily.
