Bissell Proheat 2x Revolution Carpet Cleaner 18588 5 "N of Devon" Ms MCDONNELL 26 September 2017 This carpet cleaner does a really excellent job. The stubborn stains on my carpets from mud and dogs disappeared. I was glad that I bought this model rather than a heavier one. Although the water reservoirs need changing more often, I would not have liked trying to carry a heavier model up and down stairs. The cleaner is a bit noisy but it is effective and I only intend to use it for occasional deep cleaning. Cleaning the machine out thoroughly after use is time consuming so it makes sense to clean as many carpets as possible in one session. I'm very pleased with it.
