Hi Squeaky
Funny you should bring this up now as I am researching this very machine at the moment.
A good friend of mine lives and works in the States as a Carpet Cleaner and absolutely swears that this machine is the best he has ever had (and he's had a few) including truck mounts.
This 'portable' machine can be run up to 200ft from your van and you can obtain 40 gallon tanks for the machine fitted to the van.It has built in boosters,power spray attachment and weighs about the same as any other machine.
It can be brought inside if need be and really is a real alternative to purchasing a TM.
I don't believe there is a UK distributor ,but I stand to be corrected on that, so it has to be imported direct from cross american at the moment.
Price why's in the US $2600 so you can probably double that for here as we get ripped off with every thing else don't see why it should change for this :
Further info is on the way
