Doesn't return to home base, app loses previously drawn and saved mapping runs...map drawing should be more simple than using dividers that are hard to pick up,set where you want..should just be able to set room dimensions in feet,and let robot go...every single time it says "cannot connect right now" and this is the i9+ and jet6 bundle. Too expensive for cleaning fluid, pads, rollers, not worth the 1200.00 price
