Hi Guys
I too think you would be better buying a smallish extractor .
I bought an Alltec Express, it has a twin vac and 135 psi pumps plus in tank and 2 in line heaters, so nice and warm.
It is light and will clean a wide range of carpets and upholstery and with tools would be about 2k
You then have the capability to do most jobs.
Cheers
Doug
