3 Things to Know About Roomba Navigation

Entry-level Roombas use random bump-and-turn navigation They move in a straight line until they hit something, then change direction. This leads to missed spots and longer cleaning times.

Mid-range Roombas use camera mapping A built-in camera tracks the robot’s position and maps the room. These models clean in efficient, row-by-row patterns instead of bouncing around.

Camera mapping is a significant upgrade over bump navigation It reduces cleaning time and covers more area. If you want a Roomba that actually cleans systematically, skip the entry-level models.
