This is a set of all of the different long exposure pics that I’ve taken while doing reviews of cleaning robots. I spent a likely excessive amount of time reviewing each robot in detail (and you can read those reviews at the links below), but really, the pictures explain the cleaning patterns better than I ever could. It’s illuminating (so to speak) to see them all right up against one another, so here they are:
iRobot Roomba 560 , 45 minutes
Neato Robotics XV-11 , 12 minutes
Evolution Robotics Mint (Sweeping Mode), 15 minutes
Evolution Robotics Mint (Mopping Mode), 23 minutes
Three very different robots, three very different cleaning techniques. Check out the individual reviews for more details on each.
