Product Overview
The Robot Vacuum PCBA is a fully integrated main control board designed for modern robotic vacuum cleaners (robot vacs). It consolidates motor drivers (drive wheels, side/rolling brushes), navigation sensors (LiDAR, gyro, cliff, bumper), cleaning actuators (dustbin auto‑empty, water pump for mopping), battery management, and wireless connectivity onto a single compact PCBA. This board enables manufacturers to build smart, autonomous vacuum cleaners with mapping, mopping, obstacle avoidance, and app‑based control.
The global robot vacuum market has grown significantly, driven by increasing adoption of smart home automation and demand for hands‑free floor cleaning. Our PCBA provides a scalable platform for entry‑level to premium robot vacs, supporting both LiDAR navigation (for systematic mapping) and gyro/optical sensor navigation (for budget‑friendly random/patterned cleaning).
