ROBOROCK wall sensor for S7 Black MaxV robot vacuum, 9.01.1202

ROBOROCK 9.01.1202 — wall sensor for S7 Black MaxV robot vacuum. The wall sensor keeps the robot at a steady distance from walls and furniture so it tracks the edge instead of scraping the skirting. If the robot has started grinding along walls, or conversely leaves a strip of dust beside them, or twitches in corners, this is the sensor to look at. Its window clogs easily with dust and hair, so wipe it first.
