If one his attention only on the suction, the vacuum cleaner is just great. Even if the suction power is set to the lowest level, the unit still sucks perfectly the dust and crumbs from the deepest pores of my upholstery. Since I have two cats, was particularly important for me that the cleaner also pet hair quickly and effectively sucks of upholstered furniture, without aspirating the same place several times and then still have to discover hair. This task masters of the suckers with flying colors.
Can As already said, sucking the device 1A and for that he dignified five star get if it were not for the BUT. Once you're done with vacuuming is indeed the emptying of the dust container and that is just bad! The dust is everywhere inside the appliance and you have next to the collection every time even the filter to the engine compartment and the lid of the appliance by a thick layer of dust and lint free (s. Picture). Thus, one needs after sucking still get quite a bit of time to clean the unit back and this activity should as far as possible not to carry out in the apartment, because you can then just start all over again to brush.
In conclusion, I would say, a super vacuum cleaner that sucks really great if it were not in the end would be the still very complicated purification, hence only 3 stars!
