Latest Patents
Cheng's latest patents include innovative methods to prevent wheel slip in autonomous floor cleaners. This invention features tread structures, wave motion navigational controls, and ramp-up recovery controls designed to reduce wheel slippage. The floor cleaner effectively delivers liquid to the floor as part of its cleaning process. The wheels of the device are equipped with relatively deep peripheral grooves to minimize the contact surfaces of a sprocket wheel and accommodate the layer of liquid on the floor. In cases of wheel slippage, the device is engineered to move forward with a slight side-to-side wave action by periodically altering the relative speeds of two drive wheels. Additionally, a slippage recovery mode is incorporated, where the drive wheels either shut down or significantly slow down when severe slippage is detected, followed by a gradual ramp-up of speed.
Another significant patent by Cheng is for a surface treating device with a top-load cartridge-based cleaning system. This robotic surface treating device is capable of performing various cleaning tasks, including carpet sweeping, hard-surface dry sweeping/wiping, and hard-surface sweeping/mopping. The device comprises a sweeper brush, a dust bin for collecting debris, a reel-to-reel sheet of cleaning material, and a fluid delivery system that dispenses fluid from a reservoir onto the cleaning material and/or the surface being treated. The dust bin, cleaning material, and fluid reservoir are designed for easy installation and removal from the top of the device.
