My choice has fallen on this device because it has a large water tank. I own it now for several weeks. For the normal daily / weekly cleaning you do not need such a thing actually, only when a thorough cleaning, there are possibilities. One has, however, pets, children or other dependents in the household, you can use it even more often. Mainly I've used him for removing stains in the carpet. He has done an excellent job in connection with carpet cleaner. Even the cleaning of floor tiles and the ceiling tiles in my bathroom large works fine, though you should of course polish on the wall tiles. Very annoying is the short supply. The window wiper would save Bestron prefer and are sure to put a reasonable upholstery brush. In winter you can brush no windows so anyway, it is much too narrow and everything is very wet. Well, I think, as already mentioned, the large water tank, storage of accessories in the unit, the five-year warranty and that you can descale the part with vinegar water. The price / performance ratio is ok for me.
