Replacement LDS Distance Sensor and Spare Motor Module for Xiaomi MI 1s (SDJQR01RR) Key benefits Restores accurate distance and obstacle sensing: replaces the LDS (laser distance sensor) module to recover precise navigation and mapping on Xiaomi MI 1s (model SDJQR01RR). Keeps suction consistent and effective: the module supports the vacuum's particle monitoring and binfull prompts, helping prevent suction loss from blockages and maintaining stable cleaning performance. Preserves smart floor adaptation: restores the vacuum's ability to detect floor type (carpet vs. hard floor) and adjust suction power automatically for better cleaning and longer battery life. Reduces collisions and hair jams: reenables multidirectional infrared obstacle detection to slow or steer before hitting furniture legs and wires; supports antitangle brush performance to lower hair jam risk—useful for homes with pets. What this part does Function: Replacement LDS distance sensor assembly with spare motor that integrates with the Xiaomi MI 1s vacuum to enable mapping, obstacle avoidance, and the vacuum's onboard airparticle monitoring and autosuction features. Compatibility: Specifically compatible with Xiaomi MI 1s, model SDJQR01RR. Designed for direct replacement of the original sensor/motor module. Build: Precision electronic assembly built to OEM form factor so it fits original mounting points and connectors. Uses quality electronic components for reliable performance (no change to vacuum model functions). Performance impact: Restoring this module helps maintain consistent suction, accurate navigation, and smart adaptation to different floor types—extending effective cleaning life when paired with regular maintenance. Practical use scenarios Pet homeowners: Replacing this module helps keep obstacle sensing and antitangle brush support working, reducing hair jams and improving cleaning around pet areas. Mixedfloor homes: Restores automatic suction adjustment between carpets and hard floors for deeper cleaning where needed and lower power use on smooth floors. Furnished or cluttered rooms: Reinstates multidirectional infrared detection so the robot slows or steers around furniture legs, cords, and other obstacles to reduce collisions. Notes Confirm your vacuum model is Xiaomi MI 1s (SDJQR01RR) before . This is a replacement sensor/motor module intended to restore original machine capabilities; professional or careful DIY installation is recommended.
