I have cream colored carpet. I live on about an acre of land. I live in Texas where the wind blows and the dust piles up. I have kids (sometimes 2 sometimes 9). I garden. I have chickens. I have an outside dog. I have spots all over my carpets. I can get wonderful results when I get down on my hands and knees and scrub using Resolve carpet cleaner. Wednesday I spent a full hour scrubbing just the computer room.... I decided to buy a carpet cleaner.
I purchased the bissell quicksteamer powerbrush. I followed the directions. I still have spots. I was going to return the machine until I emptied the dirty water tank and gagged at how black it was- really disgusting- maybe I'll keep it.
I'm torn. All spots will still have to be removed by crawling around on the floor with a scrub brush. However, a follow up with the bissell removed lots of gucky grime and (using the bissell products) leaves the house smelling nice- they say it will help my carpets last longer as well. It is a very easy to use machine. Easy to assemble. Easy to fill. Easy to empty the dirty water tank- just don't look at what you dump out- ick!
