For efficiency is said, which is dealing here with a floor sweeper and this is of course not the same as a vacuum cleaner. Deep-pile carpeting and deep-seated dirt is of course not be solved with this carpet sweeper. Also you often times have to go through a body part with these sweepers simply on what I feel in the least but not disturbing, since it bring out in between is still faster than a vacuum cleaner, continuously transform plugs and then having to store again. I use it mainly for our tile floor on the ground floor at times quickly crumble under the dining table, cat litter before the litter and fallen out ash and wood crumbs to remove front stove and to clean our large Schmutzfangmatte. This works flawlessly and is really fast. However, leaves, small branches and large parts can not take the sweeper. Then the sweeper is a space-saving stowed in a narrow column behind Gaderobenschrank.
The main advantage of this device is unique in its Unkaputtbarkeit! I had an electric sweeper which brought at least the same performance, but after 2 years battery and drive were broken. The same problem is the case with most battery suckers. Therefore, I opted for a mechanical sweeper and was not disappointed with the Rotaro S.
