I've been using Ashby's 400psi V2 ninja with 3kw element heater for over 2 years now, running 50 - 75' heat shrouded hoses. It stays outside the property with a silencer connected so the exhaust noise doesn't wind up the neighbours. This is an astoundingly well built machine. Some complain that its heavy - I dont attend a gym and I manage to get it around just fine. I've bought some really shoddily built poorly designed machines in the past (Masterclean) that have required some form of electrical or plumbing work on a weekly basis but I recon this Ninja has got AT LEAST another ten years in it.
As mentioned elsewhere on this forum - it isn't just the machine that produces good results, it's knowing how to use it and having the right attitude toward your work. I've had this long enough now to comment that it's a very good all rounder. Looking forward to Ashby's new high powered oversize vacuum motor built into a silencer to run inline with the two triples in the machine. (That should put the cat among the pidgeons!)
Only one minor problem... I used to like using Chemspec powders but the foam generated by these kills off the pump head (and these are not cheapy heads). The inside of the pump head looks like it's suffered from an attack of woodworm (with titanium tipped teeth), this is a common problem with hydraulic equipment when air gets into the system. (It's recognised by a special name..........No, can't remember it.) Nothing wrong with Chemspec chemicals - its just that the V2 ninja has a recirculating system so that the pressure from the inline heater doesn't blow your plumbing to kingdom come and continually recirculating highly foaming shampoo starts introducing a lot of air into the system. Any way Ashby's changed the pump head (They do have good customer service, ... if you're pleasant then you'll always get looked after. Common sense really!) and I have used Prochem ever since with top results.
