Cool vacuum cleaner for frequent, rapid cleaning of a 50-meter-squared small room. A room that is quite dusty is hardly appropriate for major cleaning. There are several odd nozzles in the kit (some even appear to be duplicates), but a flexible crevice nozzle for the automobile would have been preferable. Even so, the main nozzle with the flat roller should be at least 5 cm wider; otherwise, you must remove it in extremely thin strips. However, I must add that there are Oversize models, which come with extra batteries, a bigger tank, more power, and a wider nozzle.
