Distance Sensor (LDS) Spare Part — Compatible with Roborock S55, S6, S5 Max, S6 MaxV, S45 Max, S7 Key benefits Restores realtime air particulate monitoring and dustbin alerts so the robot warns you when the bin is full and suction may be affected. Maintains consistent suction and cleaning performance by helping prevent blockages and notifying timely maintenance; supports longer, more stable service life. Enables automatic floortype recognition (carpet vs. hard floor) and realtime suction adjustment—no manual mode switching needed, improving cleaning depth and battery efficiency. Improves obstacle detection and collision avoidance through multidirectional infrared sensing; the robot slows or steers earlier around furniture legs and cables. Works with antitangle roller brush designs to reduce hair jamming (especially useful in homes with pets), making the cleaning process smoother and less handson. What this part does This LDS/optical/infrared sensor module provides particle monitoring, obstacle sensing, and floorrecognition inputs used by the Roborock control system to: Trigger dustbin full reminders based on airborne particulate levels. Adjust suction power automatically according to detected floor type. Detect nearby obstacles in multiple directions and prompt preemptive slowing or steering. Compatibility Compatible with: Roborock S55, S6, S5 Max, S6 MaxV, S45 Max, S7. Intended as a replacement LDS/accessory to restore the above sensordriven functions on supported models. Performance and reliability Realtime detection ensures prompt alerts and timely adjustments to maintain cleaning efficiency and protect suction performance. Designed to support longlasting, stable cleaning behavior and reduce the risk of lost performance due to unnoticed blockages. Practical use scenarios Pet homes: Reduces hair tangles and notifies you when the bin fills, so the vacuum keeps strong suction and runs with fewer interruptions. Mixedfloor households: Automatically increases suction on carpets and lowers power on hard floors to balance cleaning depth and battery life without manual input. Cluttered living spaces: Multidirectional infrared sensing detects chair legs, wires, and small obstacles earlier, reducing collisions and the need for manual intervention. Notes This is a spare LDS/infrared/optical sensor accessory for the listed Roborock models. Confirm model compatibility before .
