Systems and methods include a high dump hopper system wherein a debris hopper can be split into two hoppers for positioning adjacent a wheel of the floor cleaning machine. The hoppers, split or not, can be located near the front of the machine such that the overall length of the floor cleaning machine need not be extended. A splitter can be positioned proximate the floor cleaning mechanism to drive debris into the split hoppers. The hoppers, split or not, can be coupled to a common lifting system that can pull the hoppers out from under a chassis of the floor cleaning machine and then upwards for positioning relative to a refuse container. Furthermore, the orientation of the hoppers can be controlled to position openings for the hoppers in a desired location to prevent spilling and facilitate emptying.

A patient warming system for stabilizing and/or heating and cooling a patient includes a plurality of solid-surface sections arranged for attachment to a surgical table and a warming pad layer comprising a plurality of warming pads configured for removable connection to the plurality of solid-surface sections. At least one of the plurality of solid-surface sections includes a power connector for connection to an external power source. Each warming pad of the plurality of warming pads includes a foam insulation layer, a distributed heating element layer having a warming-pad power connection for connection to the power connector, an isothermal layer, and a flexible waterproof layer. Power supplied to the warming-pad power connection of the distributed heating element layer of the respective warming pad can be used to provide a user-selected uniform temperature over the surface of the flexible waterproof layer in order to prevent hot spots.

Disclosed is a robot cleaner including a main body forming an outer shape, a water tank including a water level sensor and storing water, a pair of rotary mops to which a cleaning cloth is attached, and that moves the main body while rotating in contact with a floor, a drive motor rotating the pair of rotary mops, a nozzle supplying water from the water tank to the cleaning cloth of the rotary mop, and a controller periodically determining an abnormality in water supply to convert to a wet mop mode or to a dry mop mode to proceed with cleaning. Therefore, in the present disclosure, the sensor may be provided in the water tank to detect the water shortage in the water tank for supplying water to the rotary mop, thereby determining whether to change modes by the robot cleaner itself.

A self-cleaning automatically-stored electrical mop includes a mop rod assembly, a mop head assembly, and a cleaning base assembly used for storing and cleaning the mop head assembly. The mop head assembly is arranged at the lower end of the mop rod assembly and includes a mop head shell which is provided with a rotatable cleaning roller and a motor used for driving the cleaning roller. The cleaning base assembly includes a shell part. A cleaning groove used for cleaning the cleaning roller is formed in the shell part, and a cleaning assembly used for scrubbing the cleaning roller is arranged in the cleaning groove. The shell part is provided with a sewage discharge system used for discharging sewage.

The present invention relates to a mobile robot and a method for controlling the same. The present invention provides a mobile robot using the rotational force of at least three rotating members as a movement power source and a method for controlling the same, in which the mobile robot is controlled to effectively travel along a set curved driving path and not deviate from the set curved driving path, or to immediately return to the curved driving path when deviating from the set curved driving path.

A self-moving cleaning device includes: a base; a mobile module adjacent to the base and configured to contact a surface when the self-moving cleaning device moves on the surface; a vacuum module arranged over the base; a dust box arranged over the base and connected to the vacuum module, the dust box including a first opening and a second opening; a first suction port arranged on the base and including a first suction inlet connected to the first opening; a second suction port arranged on the base and including a second suction inlet connected to the second opening, the first suction port disposed between a front side of the base and the second suction port; a roller brush device arranged on the base and within the second suction port; and an air duct, wherein the first suction port is connected to the dust box through the air duct to thereby connect the first suction inlet to the first opening.

A robot cleaner includes a main body, a water tank including a turbidity sensor and a water level sensor, and a pair of rotary mops configured to move the main body while rotating in contact with a floor. A drive motor rotates the pair of rotary mops and a nozzle supplies water from the water tank to the rotary mop. A rotary mop controller varies an output current of the drive motor based on signals from the water tank sensors. A controller determines whether the water tank is contaminated based on the output current of the drive motor received from the rotary mop controller.
