An apparatus for cleaning a floor includes a housing, wheels by which the apparatus is adapted to move; a motive device for moving the apparatus, a steering mechanism, and a cleaning assembly including a cleaning unit and an offset mechanism adapted to move the cleaning unit to or from an offset position projecting beyond one lateral side of the apparatus. In another embodiment, an apparatus for cleaning a floor includes a housing, wheels by which the apparatus is adapted to move, a motive device for moving the apparatus, a steering mechanism, and a cleaning assembly including a cleaning unit and a swing mechanism indirectly linking the cleaning unit to the steering mechanism such that when the apparatus is in an operative mode, the cleaning unit reorients its position in synchronization with the path of travel of the apparatus. Optionally, a lifting device may raise and lower the cleaning assembly.

An autonomous cleaning device, includes: a mobile platform, configured to move autonomously on a cleaning surface; and a cleaning module, disposed on the mobile platform and including a wet cleaning module, configured to clean at least part of the cleaning surface in a wet cleaning mode.

A mobile robot. The mobile robot comprises a robot housing (10), two moving components (40), a container apparatus (20), and a cleaning component (50); the moving components are mounted on the robot housing for moving the mobile robot; the cleaning component comprises a main brush (520) provided laterally relative to a normal forward direction (f) of the mobile robot; the main brush is mounted on the robot housing and at or near a part of the robot housing, at which position a transverse width is largest; extension of the main brush in a direction perpendicular to the normal forward direction of the mobile robot is not interfered with by the moving components. The mobile robot has a larger main brush width, and thus the working width of the mobile robot is increased.

The manually operated floor sweeper is a manually powered cleaning unit that replaces the standard push broom. Designed for indoor and outdoor use, the manually operated floor sweeper provides a plurality of brushes that move dirt and trash to a hopper, which transports the dirt and trash to a receptacle. The manually operated floor sweeper comprises a plurality of brushes, a hopper system, a drive system, a gearing system and a body.

An autonomous coverage robot includes a chassis, a drive system configured to maneuver the robot, and a cleaning assembly. The cleaning assembly includes a cleaning assembly housing and at least one driven sweeper brush. The robot includes a controller and a removable sweeper bin configured to receive debris agitated by the driven sweeper brush. The sweeper bin includes an emitter disposed on an interior surface of the bin and a receiver disposed remotely from the emitter on the interior surface of the bin and configured to receive an emitter signal. The emitter and the receiver are disposed such that a threshold level of accumulation of debris in the sweeper bin blocks the receiver from receiving emitter emissions. The robot includes a bin controller disposed in the sweeper bin and monitoring a detector signal and initiating a bin full routine upon determining a bin debris accumulation level requiring service.

A debris monitoring system includes a receptacle, a first and a second emitter, and a first receiver. The receptacle defines an opening to receive debris into the receptacle. The first and second emitter are each arranged to emit a signal across at least a portion of the opening. The first receiver is proximate to the first emitter to receive reflections of the signal emitted by the first emitter, and the first receiver is disposed toward the opening to receive an unreflected portion of the signal emitted by the second emitter across at least a portion of the opening.

A robot cleaner comprising: a cleaner body including a wheel unit and a controller controlling driving of the wheel unit; a dust container accommodation part having a shape recessed toward the front from the rear thereof to be opened to the rear; a dust container detachably coupled to the dust container accommodation part, the dust container have a portion protruding rearward of a rear end of the cleaner body in a state in which the dust container is accommodated in the dust container accommodation part; and a dust container cover rotatably coupled to the cleaner body to cover the dust container, wherein the dust container cover is accommodated in the dust container accommodation part in a state in which the dust container cover is disposed to cover the dust container, and a portion of the dust container cover protrudes rearward of the rear end of the cleaner body.

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container, the flow separating part separating the flow of air introduced into the entrance from the flow of air discharged toward the exit to be respectively guided to lower and upper portions thereof.

A robot cleaner comprising: a cleaner body; a suction unit sucking air containing dust to be introduced into the cleaner body; and a dust container detachably coupled to the cleaner body, the dust container collecting dust filtered from the air introduced into the cleaner body, wherein the dust container includes: an external case including at least one cyclone filtering dust in air introduced into the dust container; an upper case coupled to an upper portion of the external case, the upper case including an upper opening corresponding to a space into which air passing through the cyclone is discharged; an upper cover detachably coupled to the upper case to open/close the upper opening; and a filter mounted on a rear surface of the upper cover, the filter covering the discharged space of the air passing through the cyclone when the upper cover is coupled to the upper case, to filter dust in the air passing through the cyclone.

A surface cleaning apparatus such as an extractor has a fluid flow path extending from a dirty fluid inlet head to a clean air outlet. The fluid flow path upstream of the separation stage comprises a removable portion.
