I bought this unit two years ago and it it is still going strong today my carpets have nere been cleaner! I have 3 Dogs and 3 cats so as you can imagine they can make a mess but with this I have no problems staying on top of those nasty pet stains. This machine is so easy to use and light weight and the carpet dries within 3 hours the fastest I have everest seen and it is so easy to clean . I would recommend this to anyone who wants a good carpet shampooer!
