I could not believe the enormous suction power can develop from 1200W. On carpeting you have to throttle the power, otherwise he firmly attaches itself. Medium power he draws very well and is pleasing quiet, you can even while listening to the radio or watching television. Going into the full load or turbo level, but then it's the quietness over, now you can hear the power also. This makes but only on hard floors sense (hard eyes on carpets). One downer was that the first unit of the connection for the electric brush was present but did not supply power. after a very short time a replacement was delivered which works great without Einschränkengen and sent back the first device again. Kudos to Amazon for easy conversion.
