The cleaning performance of the brush system is beyond almost any doubt. Even with an anti-static microfiber duster one finds only very little dust, so if you wipe the whole apartment. Long hair, lint, sand, crumbs and other debris ends up in the dust bin. Compared to our AEG Akkusauger also a few hairs or threads wrapped around the brush. Suffice it weekly to empty the dust container and pull bimonthly times hair and lint from the brush.
The random walk Wegfindealgorithmus works quite well in our labyrinthine apartment. We first need to experiment with it, where the base station is best placed. In the central hall of the robot came probably as many times around it that he gave up before he could reach everywhere. In an alcove in the living room it is better. Now the robot sucks actually thoroughly through the entire apartment. The robot especially on corners and tight niche is interested. So he leaves the job from more where normally collects most of the dust. On the other hand, has the disadvantage that it can squeeze into gaps, from which he no longer finds. In our apartment are the chair legs of the kitchen chairs.
We have the apartment have very little to adapt to the robot. Lighthouses or Virtual Walls are (after a suitable placement of the charging station) is not necessary. In one year he has left on white kitchen furniture no black stripes. At our morning routine now one simple, very undo all apartment doors, and kitchen chairs so to push under the kitchen table that the robot can not move between the chair legs.
The service is excellent from iRobot. After nine months, the robot had the problem that the brush is no longer turned. The contact with the manufacturer was very satisfactory. On a first request by email a checklist of various points came to be tested. After processing this checklist the manufacturer has sent a new free brush module within a few days, together with a comprehensible installation instructions. The robot is designed so that can be a lot of components (drives, brush, dust box, side brush, etc.) easily replaced as a closed block.
My only negatives relate to the charging station and the Virtual Walls. Both are far too easily, so you can easily push the robot accidentally through space. We have the charger attached with double-sided tape, because the robot has otherwise they often times pushed in a corner where he could no longer drive onto it. In addition, the external power supply with the relatively short cable disturbs something. An integrated in the charging station Netzeil with a long cable that can possibly roll up inside the base station to the appropriate length, would be a better solution.
Overall, we are using the robot in everyday use but so happy that we would buy a new one when our'd ever broken beyond repair. Therefore, five stars.
