Previously the 870 iRobot had. This went back because it was so vermackt after two days, that we would have him impossible several years use. So buy the expensive new Kobold. 1 month delivery time. But okay, if the device would then be beaten. When he once arrived the first disappointment. He drives around meaningless. I thought he recognizes the first apartment and then moves systematically going. 2. Disappointment: Rug without fluff with a height of 0.5 cm, it does not create. First he pushes him away, then he pushes him up, and he gets caught. Yesterday then large amazement: one day he went systematically from linieal the room, then the dining room, then the kitchen. Then it was empty. Totally surprised we thought super vllt but not so useless. Today he drove off again, totally haphazard. 3. Disappointment: the magnetic tape he simply pushes away, ramming all the things he had bypassed earlier. Cleans half an hour always the same 2 square meters. After that it was empty, even though he had all night charged. 4. disappointment: by remote control, the device can totally bad and steer delayed, it makes no fun. Are about the part to be returned. He is also very loud and blows with tremendous force insane amount of lift backwards. Although slightly higher and not at ground level, but certainly not good for people with allergies. We are on the verge Staubsaugerroboter to hang after 2 disappointments of two price ranges the topic to the Nahel. The technology is not mature, and this device too expensive !!! Let's see if we get the money back
