We have a main room of 130m² and we just did redo the roof so as first experience no worse. There is extra, he sucked really well, even large dust (even very large) accessories that fall into the grip is really good. Super suction well, you just do a little caution when stepping back the brush tends to peel off a little. Super easy to empty, and not too dirty. Little less storage, we need to have room, there is no system for winding the hose.
