Dreame D9 Left Bumper Sensor with 3 IR Cliff Sensors 16-Pin Cable Assembly
- Replacement sensor assembly for Dreame D9 robot vacuum, featuring a left bumper sensor, 3 IR cliff sensors, and a 16-pin wiring harness for obstacle detection, edge sensing, and stable internal connection.

This replacement sensor assembly is designed for the Dreame D9 robot vacuum and combines a left bumper sensor with three IR cliff sensors in one connected module. Built for accurate obstacle contact detection and drop-off recognition, it integrates with a 16-pin (2x8) connector and includes the wiring harness required for internal installation. The assembly consists of a molded sensor housing, multiple connected sensor points, and a pre-attached cable set for direct electrical connection.
The left bumper sensor supports front impact detection during navigation, while the three infrared cliff sensors help the robot detect stairs, edges, and other sudden floor drops. This configuration is essential for maintaining controlled movement and protecting the vacuum from accidental falls. Designed as a functional internal replacement part, the module supports the robot vacuum’s navigation and safety systems by restoring reliable signal transmission between the sensors and the mainboard.
The 16-pin socket layout enables precise integration with compatible hardware, while the attached harness simplifies component replacement and helps maintain proper routing inside the device. This part is suitable for repair work when the original bumper or cliff sensing system no longer responds correctly or has been physically damaged. By replacing the complete assembly, users can restore key operational functions such as obstacle response, edge detection, and movement safety, helping the Dreame D9 continue cleaning efficiently in everyday home environments.
