My Braava work perfectly for the 1st 28 days I owned it. And I would have given it 5 stars. It started to malfunction 3 days ago by backing itself against the wall and not knowing how to reset itself with the cube. It also would go in a 2 foot circle and not proceed into the rest of the room. I have 5 different areas that I use in the house and even in the small kitchen it stopped working 6 times and I had to keep placing it in front of the cube. What is unfortunate is that when I called technical support they said I am past the 30 days as it is est. by the order date,, not the delivery date. The person in technical support had me run the unit for 10 min. and since it did not malfunction in that short of time she only wanted to document the incident. I had to reiterate that I spent 2 days using the unit and it malfunctioned in a similar pattern in the 5 different areas. The technician suggested that perhaps I placed the cube in an area that didn't work with the robot or that a part was missing. This is when I became frustrated and told her she was insulting my intelligence. Why would I change the placement of the cube when it had worked perfectly for 28 days and if a part was missing I certainly would have noticed. I want to replace the unit and I'm currently waiting for a supervisor to call contact me as to whether or not this can be done
