I have carpet in the living room, it's not a big room, average size. I have a BISSELL steam cleaner, the one with the bristles, and I can empty the tank 5 times and keep going over the room and it still comes up dirty (the water) Is this normal? It's not possible to clean it until the water comes up clean is it? This carpet is probably old, we moved in a year ago so I am not sure how old it is.
I also have a steam cleaner--a Bissel Proheat 2X. (I love my steam cleaner.) It is not a good idea to steam your carpets repeatedly like that. If the carpet pad becomes saturated with water, mildew and the accompanying musty smell can result. (Guess how I know this.) Your carpet pad may be dirty. There may also be dirt under your carpet pad. I'm pulling up my carpets and replacing them; they've been in the home for about 20 years and the amount of dirt underneath the carpet pad is astounding. Your water will probably never come up clear. My view on carpets is they're someting you walk on, so they may be a little dirty!
Clean the best you can.. You d be absolutely shocked at the amount of dirt is under the carpet and pad even in the cleanest of houses.. I ve pulled up many carpet and the home owners are appalled at the amount of dirt that is under there. GL
