Yes I use my machine on the carpets all the time. I have a brush type head which I fit a cloth to and then slowly run the head over the carpet. You can use it without the cloth on mats but a cloth will absorb the dirt at the same time. The Vax does however clean deep down but a Vax does not kill off the bacteria. Best of all the steamer kills bacteria without the use of chemicals.
It pays to buy a good steamer/vapour cleaner if you have a large house and plus you want a good high temperature and bar pressure at the wand end so it kills deep down. Mine can be adjusted depending on the pressure you wish to use. I also use it to clean my sofa but care must be taken on different materials as the high temps can damage.
I also use it on my tiles in kitchen and conservatory. You can also get extras like a wall paper stripper. You do have to be careful round paint work. It will lift paint work if directed for any length of time onto it.
Some steamers also come with a built in hoover but I don't know what they are like to be honest.
I like the Polti one I have due to the fact the handle has no electrics, a safty cap to prevent you being burnt, a stainless steel boiler, lots of extras and good after service from the company if spares are needed. It can also be used continuously without the need of stopping and waiting for the steam pressure to build up.
If possible perhaps it would be worth you hiring one from a hire shop to see how a steamer feels before buying one.
I'm sweet and cute and single.
