Love it!
Rented a Rug Doctor for years. Took the plunge, and bought a used one on fleabay. (How much use would a home unit get? - Certainly less than the rentals, and the rentals have a 10 year lifespan!). You have to read the instructions to use. And yes, it is heavier.... it carries a lot of cleaning solution! It's a heavy-duty cleaner - better than the lightweights from competitors (had a Bissel and it was useless). Only downfall... is the plastic upholstery 'wand' on the end of the hose. It is prone to cracking and you can't buy just the replacement wand from rug doctore... you have to buy the wand and hose. The fix for a broken plastic wand? Fleabay sellers sell a stainless steel wand (will never break!) which is far superior to the plastic wand offering from rug doctor.
