Honda engined pw are one of the best but at the same time one of the higher priced.
Whirl away on ebay are a cheap rotary cleaner, you can get a domestic karcher but if you go down that line you would want the dopmestic pressure washer that is not really up to the job.
15L a min 200psi drives a flat surface cleaner
I have a honda engine and whirl away it is more than man enough for this job.
