Just started using the robotic vacuum, works well.
However I have a small area I’m cleaning, robot says 450 sq ft. It takes 1 hour to clean, and with high suction, battery will not cover it. I would muse in at my lake home but 1600 sq ft would take 4 or more charges, I also have a neato d3, and it can do the same room in 35 minutes.
I notice that when vacuuming the robot does much overlap. When traveling back and forth it moves only about 3 inches to the side per pass. (The neato covers full vacuum width or about 12"). The brush and cleaning area is more tha 6" wide so it is covering every spot at least twice. It takes 4 times as many passes as the neato.
If not for the battery and time taken this is good. But it would be good to have a configurable option to change the path width to full brush with to reduce clean time and coverage per charge.
