can anybody help me i am looking for a good but reasonably price carpet steam cleaner. i have lived in my house for nearly four years but still have some of the original carpets from when i first moved here. unfortunately i seem to get alot of stains appearing on the carpet that i think must come from the underlay but at the moment i dont want to have to replace it, so i thought i would clean them. dont really want to have to fork out for shampoo but i thought a steam cleaner would be good. any suggestions?
