Now the vacuum cleaner is here and it always fascinates me anew as this device carries out his work. Anticipation before, have a very long time, for which device I should make up my mind. Reviews there is not much but for other devices rather splurge. Ultimately for me was crucial the room size to 100m² (it may be more), the volume (really quiet). He is nowhere abuts not quite right because he does sometimes but already at low speed. Hi, maybe the braking distance is indeed too long. The operation of the device is really easy to handle and empty the dust container as well. Language is already set on delivery in German. Having a timer programming for weekdays as other equipment is not necessary or sensors which determine a space any more for me. When he is not to approach a room then I'll close the door. Just press start and everything else makes the device. I have parquet and Kurzflourteppiche he cleans easily. Doorsteps of 1,2cm holds this unit on. 2cm he not unpacked. The problem I have resolved as I have extended the sales to a wooden tie from the hardware store, the vacuum cleaner leaves from every room and if he thinks it is somewhere not properly cleaned then he goes to the field at the end of again. Battery performance is perfectly adequate for my 100sqm unless he wants to start again for more thorough cleaning, because that could be scarce. If the battery but is weakening, he drives automatically returns to the charging station and makes after charging the rest from the spot where he finished has stopped. Who is such a device should also be taken into account At length he can not reach with its diameter of 36 cm throughout. So he does not entirely replace a normal vacuum cleaner. Overall, it is worth the price and I am fully satisfied with his performance. By the way, my cats enjoy off also.
