Super convenient and efficient, having a dog at home RoboMop picks hair, dust and small crumbs in the late afternoon. He never stays stuck. a 15-minute program will be sufficient for my area of 20m2 but the smallest is 30 minutes. 1:30 Total autonomy is 3 program for 30 minutes to 5 hours of loading. autonomy and charging time are the only negative points because this robot is very effective and fast.
