Roborock Auto Empty Dock Rear IR Sensor for S7 Pro Ultra / S7 Max Ultra

This rear infrared sensor is a dedicated replacement component for the Roborock Auto Empty Dock used with S7 Pro Ultra, S7 Max Ultra and S7MAXV Ultra robot vacuum systems. Designed for accurate dock detection and smooth docking support, it plays an important role in helping the robot identify the station correctly and maintain stable charging and return-to-base performance. Built as a precision PCB-based infrared sensing module, this part connects directly to the main board interface of the dock. Its construction is engineered for dependable signal transmission and proper communication between the docking station and the robot.

The sensor supports essential functions related to navigation near the dock, including station recognition, alignment assistance and charging guidance, making it a critical element in the docking process. The module is intended as a rear-position infrared sensor and matches the technical role of the original dock component. Its compact board design allows integration within the docking assembly while maintaining the required electrical connection and sensing performance.

As a replacement part, it is suitable for restoring the correct operation of a malfunctioning or worn dock sensor in compatible Roborock stations. By replacing a faulty IR sensor, you can help recover reliable docking behavior, reduce charging interruptions and improve the overall usability of the cleaning system. This makes the component a practical solution for maintenance, repair and long-term performance preservation of your Roborock Auto Empty Dock.
