I got myself the identical model of TCM (Tchibo), actually just to get by former carpet (medium pile height) in the living room, the cat hair off, the difficulty managed our 2400 W vacuum cleaner with turbo rotating brush. And I must say, I felt better, even good. Meanwhile, we have carpeting (Velour) and to pre-cat hair removal device is well suited. You would not believe how much can a pig in his carpet ... After 10 m² should be emptied, otherwise he spit everything back one's feet. With a charge we create about 30 m². On smooth surfaces, the device is not recommended, regardless of whether tiles or linoleum.
