Have the automatic return suction only a short time in Gebrauch.Er works quite carefully the entire apartment from leaves and a surprised look on as he but his tracks zieht.Der Robbi can (also available in the manual) Replace no "right vacuum cleaner". Nevertheless, he is a workload as it where you have to suck itself can significantly delay the interval. The device works well finished and is easy to handle and maintain. The few criticisms that I want to pass on: If the NaviBot has depleted its energy and brought his work to the end, it comes down to how far he's away from his charging station, whether or not it can automatically start up its station. Is it, for example. two spaces away from the station, he drives around only uncontrolled and lurches haphazardly and disoriented on the furniture and walls along until it eventually gives up and switches off. Therefore, one can not leave him well alone unattended, also it may happen that he is somewhere verfranzt .It may on the desk which no thin cable (zb.Kopfhörer), no wool in the wheels or lightweight women's shoes which he apparently does not like in his career otherwise it is switched off. However, it is very spectacular skill with which he herausmanovriert from the tightest corners and how he's charging station after work (if he is in the same room) can move. On the whole, I can do that product, you should however already bring fun and joy in the art and do not expect a perfect working tool.
