Roborock QRevo Back IR Sensor PEARL PLUS B-IRM B1 for Docking Station, Black

The Roborock Back IR Sensor PEARL PLUS B-IRM B1 is a dedicated replacement component designed for selected Roborock QRevo series robot vacuum docking systems. Engineered for infrared communication and accurate dock alignment, this sensor supports reliable operation of the emptying, washing and refill station, helping the robot return to the base smoothly and consistently. This component features a compact PCB-based construction with durable plastic and metal elements, a black housing, and a dual-socket design for secure integration with the docking assembly. The insert-fit mounting format enables straightforward installation, while the lightweight build of approximately 50 g supports easy handling during servicing or replacement.

As a new replacement part, it is intended to restore original docking communication performance when the existing sensor is damaged or no longer functioning correctly. In practical use, the Back IR Sensor plays an important role in transmitting and receiving infrared signals between the robot and the docking station. This supports precise positioning during the docking process and helps maintain proper interaction with the station during automated maintenance cycles.

Compatibility includes selected Roborock QRevo, QRevo MaxV, QRevo S, P10 series models and EWFD16HRR empty docking stations, depending on the exact version. Choosing this Roborock sensor helps maintain efficient docking behavior, reduces communication errors and supports uninterrupted daily cleaning routines. It is a practical solution for repairs, preventive maintenance and restoring full station functionality in compatible robotic vacuum systems.
