Purily AI Robot Co., Ltd.
Purily (brand HydraRobo) designs and manufactures AI-powered robotic pool cleaners that navigate autonomously underwater. Its robots use self-developed ultrasonic navigation sensors and an ultrasonic mapping system for intelligent path planning (S-shaped floor and N-shaped wall patterns), a six-axis gyroscope, and real-time obstacle detection/escape. Models offer hybrid AC/DC and cordless 9000mAh operation, 4-drive-motor drivetrains, and wall-climbing to 90 degrees for floor-to-waterline coverage.
