Why would you want to use a steam cleaner on a painted wall? I guess it would depend on what the wall is made of and what type of paint. Flat latex paint on drywall - I would pass on the steamer and instead spot clean with a moist microfiber cloth. Better at getting out stains from carpet and grout? Any of the good units will do fine - it is the technique of the operator that will make the difference. It is difficult to compare the machines because the information depends on how the company chooses to present it. From what I read, are that you want a stainless steel boiler and a long enough cord for convenience. Then you want to compare temperatures in the boiler and at the tip. The warranty should tell you something about the machine as well. I wish that Consumer Reports would test them.

I have one of the pricey "dry" vapor steam cleaners, from allergybuyersclub site, the tidyvap. I like that site and frankly am surprised they OK'd it for your floors and walls. DO NOT use it on painted walls! It will remove paint, or at least discolor the area you use it, plaster or drywall (drywall even worse). It is very intense heat, and would scald your hand if you used it on skin, so I would not recommend it for wood, either (although I am unfamiliar with trax?). I have used it on UN-painted wood to spot clean adhesives, but I would not regularly use all over wood floors, as I bet it would warp the boards. The machines are WONDERFUL for tile, stone, metal, glass... it is a miracle machine in the bathroom and kitchen, no chemicals and cleans to sparkling new. It is OK for rugs but frankly a little too labor intensive to clean the whole thing regularly, I have only spot cleaned rugs too. (Cat throw up - great for that!) I don't have allergies but these machines are recommended specifically for dust mites, because the heat kills them, and it can be used on cloth/furniture and mattresses effectively. A very good HEPA vacuum (Miele is the cadillac, I love my Oxygen) would be a much better bet for dander and you could use it on walls/wood floors. Dander is superficial, and you won't need the most deep cleaning to keep it clear. You could also get a wet steam cleaner like the shark and try that, but I think a good HEPA vac is all you need.

The steam mops are the inexpensive version of steam cleaning. Compared to the more expensive canister models, they have a smaller water capacity, don't get the water as hot, and don't offer optional cleaning tip accessories. But people like them for cleaning floors. I have the Vapor Clean TR5 (not recommending and not not-recommending - just stating) and it cleans well. If you do a search here with the words "steam cleaning" you should pull up a lot of threads. Generally speaking, a unit with a stainless steel water tank and a gauge for pressure and temperature is probably a higher end machine.

It probably would do a fine job,just remember the accessories will cost more. The link you posted was broken,the fixed link is below. Here is a link that might be useful: Wagner DTS 5800 steam wallpaper stripperl
