Long chose, but settled on this model. I have a very complex layout. Apartment 120m, m of transitions, 3 entrances to the kitchen, L-shaped corridor from which 8 exits lead, etc. Everywhere DARK brown parquet (for many robots dark color is a problem) and tiles, plus 3 bedside carpets with long pile. There were no problems with these surfaces. Sometimes I only lost a small brush in the pile of the carpet. On one charge, he never mastered everything, but after recharging he removed the rest. A little noisy, but I ordered a combo brush from Ali, which comes in a more expensive model, HEPA filters and small brushes, and it became noticeably quieter. For a combo + 3 filters + 3 brushes I gave 2022 Here only for combo + 1 filter they ask for 4500! I have two small children who constantly run around the apartment. I used to vacuum every 3 days. Otherwise, dust began to appear on the dark floors, which was terribly annoying. The robot took over this problem. Of course, it will not replace a full-fledged vacuum cleaner and washing floors, but it helps a lot. In general, the purchase is satisfied. Worth your money.
