A method operates a mobile, self-propelled appliance, in particular a floor-cleaning appliance such as a robot vacuum cleaner and/or robot sweeper and/or robot mop. In which method a user predefines, on a portable accessory, which cleaning tasks are to be performed in a predefined time window and determines a number of performances in this predefined time window and also further cleaning parameters and/or boundary conditions. The mobile, self-propelled appliance automatically generates a task allocation as to when which cleaning tasks are performed in the predefined time window with the provided cleaning parameters and/or boundary conditions.

A method for controlling a mobile, self-propelled appliance, in particular a floor cleaning appliance such as a robot vacuum cleaner and/or a sweeper and mopping robot so as to mop up an accumulation of liquid, includes driving on a floor surface intended for cleaning in a direction of travel in a forward movement of the appliance and cleaning the floor surface by using a dry cleaning module and/or a wet cleaning module of the appliance. The accumulation of liquid is detected in the direction of travel in front of the appliance in a moist area. The forward movement in front of the moist area is terminated and the appliance is rotated about substantially 180. Driving on the moist area in a reversing movement in the direction of travel of the appliance and mopping up the accumulation of liquid using the wet cleaning module is carried out.

A water tank is provided for communicating with a cleaning system on a base station body of a base station and outside of the base station. The water tank includes a clean water cavity configured to hold clean water, a clean water input channel configured to be communicated with the clean water cavity and an external water source outside the base station, a clean water output channel configured to be communicated with the clean water cavity and the cleaning system on the base station body, a sewage cavity configured to hold sewage, a sewage input channel configured to be communicated with the cleaning system on the base station body and the sewage cavity, and a sewage output channel configured to be communicated with the sewage cavity and outside of the base station.

An industrial floor scrubber includes a solution tank and delivery system for applying the solution to the floor, and one or more rotating brushes for removing dust and debris from the floor and respectively directing same to a squeegee and to a debris hopper. The trailing squeegee removes the remaining solution from the floor and, in combination with a vacuum system, directs the recovered solution to a cleaning solution recovery tank in the scrubbing mode of operation. In a sweeping mode of operation, the use of a dust filter is eliminated as the dust-laden air is directed past the debris hopper and onto the upraised squeegee which confines and directs the dust-laden air into a spray of fine water particles which adhere to and transport the dust-bearing water particles to the recovery tank via an applied vacuum. The heavy dust-bearing water particles drop into the recovery tank, while a demister removes the remaining water vapor with the dry air discharged to the atmosphere via a vacuum impeller.

A surface cleaning apparatus includes a housing including an upright handle assembly and a base mounted to the upright handle assembly. The surface cleaning apparatus is further provided with a fluid delivery system comprising a fluid dispenser configured to dispense fluid and at least one fluid delivery channel forming a portion of a fluid delivery pathway. A method of removing debris and fluid from a floor surface using a surface cleaning apparatus is also provided.

A floor cleaning apparatus is provided, including a dirt collection device for picking up dirty liquid from a floor surface to be cleaned as well as a dirty liquid tank, into which the dirty liquid can be transferred. In order to provide a floor cleaning apparatus of this type, which can be handled in a more user-friendly manner, it is proposed that the floor cleaning apparatus has a tank rinsing mechanism with at least one rinsing line, which includes at least one inlet opening for rinsing liquid, which can be provided for the tank rinsing mechanism, as well as at least one outlet opening for delivering rinsing liquid into an interior of the dirty liquid tank.

A surface cleaning apparatus includes a housing including an upright handle assembly and a base mounted to the handle assembly and adapted for movement across a surface to be cleaned The surface cleaning apparatus is further provided with a fluid delivery system comprising a fluid dispenser and at least one fluid delivery channel forming a portion of a fluid delivery pathway. The fluid delivery channel can be formed by a portion of a suction nozzle assembly on the base. A light provided on the base can be configured to illuminate the fluid delivery channel when cleaning fluid is being delivered.

A surface cleaning apparatus includes a housing including an upright handle assembly and a base mounted to the upright handle assembly and adapted for movement across a surface to be cleaned. The surface cleaning apparatus is further provided with a fluid delivery system comprising a fluid dispenser configured to dispense fluid to a brushroll and at least one fluid delivery channel forming a portion of a fluid delivery pathway. The fluid delivery channel can extend adjacent to a portion of the suction nozzle assembly. An interference wiper interfaces with a portion of the brushroll to remove excess liquid from the brushroll.
