Some things I would like to say:
- We have a 80sqm apartment, the charging station is in the bedroom. The Roomba 770 can not communicate with the (not included here, working for other models) Lighthouses, but he has always independently after cleaning of 3 (narrow) room (approx 68sqm) found back in the charging station, all the rooms were quite clean (initially were here and there small dust residue, but more often the Roomba, the less mess stays). If one is not important that all spaces should be drawn in time of equal length, Lighthouses are unnecessary in my experience.
- One also has no dogs, cats or carpets (as we did), the maintenance of the equipment is done very quickly. Occasionally, a few hairs wrapped around the brush, but this is quickly solved.
- Some reviewers to read, the Roomba would bounce quasi high speed in dark furniture, I can not confirm, but we have a lot of dark furniture, but any damage, etc. come in the observed maximum speed of the device is not really in question.
We are very satisfied with the device and do not want to miss it! It's great to come home and be found a spotless apartment, while the Roomba full and satisfied slumbers in the charging station. The cleaning of the device even fun for me what my girlfriend a little surprised; Before, I was rather less charmed by cleaning processes :-)
