Hi Alan,
I've had my old Prochem Steampro since the early 1980's, when I did my carpet and upholstery training with the great Ron Tilley and it's been 100% reliable over all that time.
I stopped carpet cleaning for some years, just doing the odd carpet and bit of upholstery now and again over the years.
This year I decided to get back into carpet and upholstery cleaning again and looked at all the new portable machines on the market, things have moved on so much now. In the end I bought the Ashby's Enforcer with in tank heater and 400PSI pump, it's a great machine for my needs and really well made.
I've all ways liked Prochem's machines, but prefer an in tank heater, which Prochem no longer do and a variable high pressure pump . As well as looking at Prochem's machines I would also look at others from Ashby's range, Alltec and Cleansmart as well.
Regards Phil
