We are highly satisfied with the cordless electric broom from Kärcher. He does exactly what it should: 1 A suck. If you open the debris tray and empty scare you, how much dirt you but so has in the apartment, which is not visible otherwise ;-) This result is achieved by no means a normal broom. For battery life I can still give a final judgment - I'm so far but satisfied. We have the broom now since about 1 week and return with it every day the kitchen and living room. So far we had the battery not recharge again. *** Strong buy recommendation ***
