I must say I wasn't expecting too much just something to freshen my carpets, I was really surprised at how effective this little cleaner was. Most of the reviews I read were positive and I wasn't put off by the small amount of negative reviews. I have a few tips, it looks like a vacuum cleaner so the temptation is to use it like one, you need to remember that it needs to be used much slower to give it time to spray on the detergent and lift the dirty water up too. it made a really, really grweat job of my cream coloured carpets and even more surprising left them virtually dry. I really can't recommend this highly enough, I'd recommend cleaning it thoroughly after to stop it getting clogged up. This is my best buy for years!!
