Now Robert has been around for a few months in operation, time for a little scoreboard: He is doing his job as shown in the description. To this end, but small things are taken into account: He can "lock up" when doors open inwards, for example, and can not be fixed with a doorstop. He can get stuck under chairs eg if their leg distance is large enough to pass him, but small enough for the subsequent "aberration" is. Sleepers he copes actually quite good, but sometimes he gets stuck. The little things shown are no errors of the device, if the apartment is prepared accordingly, he does his job. The HEPA filter to clean easily blow through, so blow the dust equal to the dustbin.
