There is a Karcher electric broom for 5000. and this dyson. So Karcher performs its task by 5 points, daisno by 2. It does not in the corners, it will not a piece of paper into the floor of a bill. Bottom line: the apartment was not completely cleaned due to low power + due to a dead battery. In order to vacuum the floors normally (Iβm generally silent about carpets, etc. ), you need a vacuum cleaner with a wire to the outlet (such are many times more powerful). For easy cleaning, an electric broom, just like a dyson does. And, for high-quality cleaning, you need a normal vacuum cleaner.
