About carpet sweeper I have read virtually every available review, because I needed a useful, fast tool to the dog hair on our carpet to master. Thanks to the good reviews about the Leifheit carpet sweeper I chose this one. My choice was the right one. Within a few minutes provides a previously polluted velor carpet, on which the hair glue almost, again clean out. The carpet sweeper creates the problem even better than the vacuum cleaner and is cleaned in a very short time and with few handles again. Some people write you need a little comb to clean the brush. We have a dog with long hair (German Shepherd), but I had to brush comb never, although I use the thing for a month every day at least twice.
