Product: Replacement Distance Sensor (LDS) Module for Roborock S55 / S6 / S5 Max / S6 MaxV / S45 Max / S7 Key benefits Keeps suction consistent: realtime particle monitoring helps detect airflow blockages and prompts dustbin cleaning to prevent loss of suction and degraded performance. Extends useful life: timely maintenance reminders and accurate sensing reduce wear from clogged filters and motors, helping the vacuum run reliably for longer. Smarter, more efficient cleaning: automatic floortype recognition and dynamic suction adjustment deliver deep cleaning where needed while conserving battery on hard floors. Safer navigation and fewer interruptions: multidirectional infrared sensing and obstacle detection reduce collisions and entanglements, lowering the need for manual interventions. What it does Airflow particulate monitoring: infrared/optical sensors monitor particulate concentrations in the airstream and trigger dustbin full alerts so you can empty the bin before suction drops. Floor sensing and auto power adjustment: builtin sensors detect carpets vs. hard floors and adjust suction power in real time—no manual mode switching required. Obstacle detection: multidirectional infrared sensors identify obstacles such as furniture legs and cables and slow down or steer to minimize impacts. Antitangle support: compatible with machines that use an antitangle roller brush design, reducing hair jams and improving performance in homes with pets. Compatibility Designed for Roborock models: S55, S6, S5 Max, S6 MaxV, S45 Max, and S7. Fits as a direct replacement for the original LDS/distance sensor module used by these models. Performance and reliability Maintains stable cleaning performance by preventing suction loss from blockages and enabling smarter maintenance. Improves cleaning efficiency through automated suction control and better obstacle avoidance. Especially useful in multisurface homes and pet households where hair and debris can quickly reduce performance. Practical use scenarios 1. Pet household: the sensor + antitangle roller brush combination reduces hair jams, alerts you when the bin is full, and maintains strong suction for consistent pethair pickup. 2. Mixedfloor home: the vacuum automatically raises suction on carpets and lowers it on hard floors, delivering deep cleaning where needed while conserving battery life. 3. Cluttered living space: multidirectional infrared sensing helps the robot slow down and steer around chair legs, wires, and small obstacles to avoid collisions and interruptions. Installation and maintenance notes Intended as a spare replacement part for the listed Roborock models. Install according to the manufacturer's instructions or have it fitted by a qualified technician. Regularly empty the dust bin and clean filters as prompted to preserve performance and extend component life. If you need a direct replacement to restore intelligent sensing, automatic suction control, and reliable navigation on your Roborock S55 / S6 / S5 Max / S6 MaxV / S45 Max / S7, this LDS distance sensor module is designed to restore those core functions.
