AI Technical Summary
Existing robotic pool cleaners face limitations in maneuverability, stability, and suction efficiency due to their propulsion systems, particularly those with two driven wheels and additional brushes or tracks, leading to imbalanced movement and difficulty navigating confined spaces and obstacles.
A robotic pool cleaner design featuring a single motor-driven axle with two drive wheels and a third free-spinning wheel, combined with a large-diameter propeller and non-return system, enhances maneuverability and suction capacity, allowing seamless navigation and efficient debris collection.
The design improves handling, reduces manufacturing and maintenance costs, ensures stable movement across various surfaces, and optimizes cleaning efficiency by increasing suction force and reducing clogging risks, thus providing high-performance pool cleaning.
