We bought one week ago the v50 ultra complete.
- it doesn't fall down when there is a step in front of it, it recognizes the empty space below
- it recognizes your pet and send a photo to your phone using the app
- it cut the hairs that it aspires, so they don't block it
And obviously it scans your house and create the best pattern to clean based on the fornitures, type of tyles, room disposition...
You can set to clean a single room, a zone, a whole floor (you can scan more floor if you need).
You can also add a pet detergent to remove nasty odor.
Soo 10/10, we recommend it
