After the initial enthusiasm of the children for the new pet and the acclimatization we do not want to miss the Robi. Power good clean and leaves in the middle of nothing. Can return twice over large areas and can be started for a 90 ° angle. The starting point and the orientation makes a little difference. It's amazing what the Robi has brushed after thorough vacuuming, which we liked. The manual suction mode is a useful remote controlled vehicle and makes the boys still fun. This also applies to the study of the patterns of behavior and the "fret" with snippets or obstacles. The result depends certainly on the furniture etc.. We have sofas and beds with enough distance to the ground. As will be better cleaned as possible by hand with suckers. Chairs should be out of the way and the IKEA-Poäng place of Robi not so hot, and turns due to the rear from Leist. Otherwise, the Robi master the course with stairway, sofa and guest toilet awkward angles well. All alone is, however, nothing, hence the decision for 8845 with a lower Funktiomsumfang (and lower price) correctly. Time delay for the start and the different modes ranging completely for us.
