The Combo AI robot vacuum barely cleans the wall edges while vacuuming and mopping as well. Almost 2 inches from the wall almost had all the white stuff I poured to test the edge cleaning. Check the vide link here -> (https://www.youtube.com/watch?v=JzAi6HqBHf8). A robo vacuum at this price with such performance is surprising to say the least.. However, other regular areas that it does clean up (vacuum or mop), it does a good job. Not just the edges. The way the mop pads are position at the rear with respect to the curvature of the robo itself, it seems like it was never meant to mop close to the wall when it goes in a straight line next to the wall. Same is the case with the brush. Hardly touches the edge of the wall when the robo moves in a straight line alongside the wall. So design wise, it does not look like it was meant to clean close to the edge. So I am not sure if I am missing any setting that would fix this.
