Basically: keep "him" what "he" promises. However, there is no carpet in our apartment - so I can not judge the suction result for carpets. He is charged in 3 hours completely, on hard floors is usually sufficient level 1 and thus it will remain at the 35 min. Specified suction. Stage 1 = low, 2-third Stage it is very loud! The accessories I have not yet used. Stairs and upholstery can also be so easy, and handy suction. I am satisfied and happy not having to constantly strutting a sucker behind me and look for the cable.
