dont waste your money.
Most suppliers sell a compact machine with half decent psi and vac power for lugging upstairs
into flats or where access is an issue with your main machine. Check out cleansmart/alltec/solutions....
Karcher puzzi is not the machine you want in my opinon....... i used to use one many moons ago for
cleaning car upholstery, but i would not consider it for carpets.....
