Bought about 4 weeks ago. So far I am very satisfied with this robot vacuum cleaner. The room I clean is carpeted and has an area of about 500 square meters. ft. The vacuum has a very random cleaning pattern, but it does a good job of keeping my carpets clean. I run it twice a day. I'm really surprised how much dirt and pet hair this little vacuum cleaner picks up. I run it on Boost IQ. Initially used the Max setting but found Boost IQ to work just as well. Pretty quiet operation. Deducting 1 star because I can't get my hair out of the curlers. I've done a lot of research and this seems to be a common complaint with most robot vacuums. I have attached a video showing how to dock the device. The instructions said that docking takes up quite a bit of space on either side, but I didn't have space that was acceptable to me. I tried it next to the TV and the stairs and it found its way back to the charging station every time. It rarely gets stuck, but I put chairs on the table to make it easier to maneuver. There are literally inches between the device and a ladder or TV stand. You only need a direct shot to the charging dock to dock properly.
