Query: deep cleaning!

I have rented carpet steam cleaners in the past and was always delighted & disgusted in equal measure. Disgusted by the dirtiness of the water & delighted to think I was getting my carpets so clean. I hesitated to buy a consumer model, but the Hoover F5914-900 SteamVac's results made me happy I made the leap.The assembly was not difficult & I know I will be saving money soon as I will now steam clean quarterly. The water was just as black (gross!) and my whole house smelled better. I have wool area rugs and give the Hoover 5 stars for my results. For any pet owners, this is a must-have!!
