Not impressed with this app or irobot. Mapping is quite difficult and robot won't follow it anyway; Tried to make it not push things, but does it anyway, nothing broken yet but it tries; takes up to four hours to do about 1300 square feet because it repeats itself. The mop however seems to work just fine, but have to carry it to two areas due to carpet. And did not like their same as cash program. Paid off early and can get their bank to stop sending me stuff.
