Title: Wish I had bought this years ago!
Product review: This is a great machine. The cost of it equals about what I was paying for commercial carpet cleaning for my house each time. But this does a much better job. (The color of the rinse water that this machine produces is truly astounding---gross!) The hand tool works nicely on stairs. The only cautions I would give are:(1) You need to refill the clean water tank with hot water fairly frequently;(2) Don't carry the water tanks (upper or lower) only by their plastic handles when they are filled with water---the handles can crack under the strain of the weight. This happened to me, though Hoover was really great about replacing them for me.
Would you say this review depicts the product in a flattering or unflattering light?
