There has been a bit of chat on another thread about 'super' hot pressure washers. There are lots of other all in one machines from the likes of karcher, nilfisk and independant manufacturers. Has anyone used them? For general pressure washing is there much point in them? They claim about 12l min at 100 bar or 10l min at 150 bar and temperatures up to 150 degrees. I'm looking to get a new bit of kit.
