Abstract: A robotic floor cleaning device that features a controlled liquid releasing mechanism. A rotatable cylinder with at least one aperture for storing a limited quantity of liquid is connected to a non-propelling wheel of the robotic floor cleaning device. There is a passage below the cylinder and between the cylinder and a drainage mechanism. The cylinder is within or adjacent to a liquid reservoir. Each time an aperture is exposed to the liquid within the reservoir it fills with liquid. As the wheel turns the connected cylinder is rotated until the aperture is adjacent to the passage. The liquid in the aperture will flow through the passage and enter the drainage mechanism which disperses the liquid to the working surface. The release of liquid is halted when the connected wheel stops turning.

Abstract: An expandable wheel has rollers arranged radially about a plate within a main housing. Spokes pivotally connected to the plate are attached to linkages on which the rollers are mounted. The rollers and linkages protrude through apertures in the main housing. The rollers form the circumference of the wheel. Rotation of the plate relative to the main housing changes the angle of the spokes relative to radii of the plate. When the spokes are parallel with the radii of the plate, the rollers are pushed radially outward at a maximum distance from the plate, forming the largest wheel circumference. When the spokes are as near perpendicular as possible with respect to the radii of the plate, the rollers are pulled radially inward at a minimum distance from the plate, forming the smallest wheel circumference.
