A vacuum cleaner system includes an agitator and nozzle assembly having an agitator configured to rotate about a pivot axis and a suction tube. The agitator includes an agitator body having an agitator suction inlet and defining a suction tube chamber. The suction tube chamber extends along at least a portion of the pivot axis and includes a suction tube opening disposed at one end thereof. The suction tube is received through the suction tube opening and partially into the suction tube chamber, and includes a suction tube inlet. The agitator is configured to rotate about the pivot axis relative to suction tube such that the agitator suction inlet and the suction tube inlet partially overlap and an air flow path is established which extends through agitator suction inlet, into suction tube chamber, through suction tube inlet, and into the suction tube.

Described herein are systems and methods for assessing a health status of a cleaning head assembly in a mobile cleaning robot. The mobile robot includes motorized cleaning member that rotatably engages a floor surface to extract debris. An exemplary system includes a processor circuit that receives robot data produced by the mobile cleaning robot traversing an environment, determines a robot parameter using a portion of the received robot data corresponding to a floor area having a specific surface condition traversed repeatedly by the mobile cleaning robot, and determines a state of the cleaning head and an estimate of remaining useful life of the cleaning head based on the robot parameter. The determined state of the cleaning head system can be provide to a user via a user interface.

A robotic cleaner may include a body, an agitator chamber within the body, an agitator disposed within the agitator chamber, a dust cup removably coupled to the body, the dust cup including a debris inlet, the debris inlet fluidly coupling the dust cup to the agitator chamber, and a shutter configured to transition between a cleaning position and an evacuation position in response to rotational movement of the agitator.

A robotic vacuum cleaner includes a main body having an underside configured to face a surface to be cleaned, a suction opening that opens into the underside of the main body and extending transversely to a main direction of travel of the robotic vacuum cleaner; and a first side cleaning member attached at a fixed location on a front part of the main body and located adjacent a first side edge of the main body, the first side cleaning member having a first cleaning part which is flexible and is configured to direct waste, which comes into contact with the first cleaning part when the robotic vacuum cleaner moves in the main direction of travel, toward the suction opening.

A mobile robot system includes a docking station and a mobile robot. The docking station includes a platform, first and second charging contacts on the platform, and first and second ramp features on the platform. The robot includes a housing, first and second drive wheels, first and second raised charging contacts on a bottom of the housing, and a cleaning module including at least one rotatable cleaning head that extends below the bottom of the housing. The robot is movable from an approach position with the robot spaced apart from a front of the platform to a docked position with the robot on the platform and the docking station charging contacts engaged with the robot charging contacts. As the robot moves from the approach position to the docked position, the robot engages the first and second ramp features and the cleaning mechanism is lifted over the docking station charging contacts.

Described herein are sensor assembly cleaning systems and apparatuses that are adapted to rotate a transparent surface of a sensor assembly independently of a housing of the sensor assembly in order to disperse water, moisture, debris, or the like from the surface. The transparent surface may be a glass window that provides a camera of the sensor assembly with a field-of-view of an external environment. Sensor data captured from various on-board vehicle sensors such as moisture data, image data, vehicle velocity data, or the like can be evaluated against various criteria to determine when and for how long to rotate the transparent surface. Sensor data can be evaluated over a period of time to identify patterns or trends relating to one or more vehicle parameters. An activation schedule for initiating and ceasing rotation of the transparent surface can be determined based on such patterns/trends.

A docking station for a robotic cleaner may include a base, the base including a support and a suction housing, a docking station suction inlet defined in the suction housing, the docking station suction inlet being configured to fluidly couple to the robotic cleaner, and a docking station suction motor, wherein the docking station suction motor is activated after the robotic cleaner is determined to be docked with the docking station and in response to a triggering event.

In general, the present disclosure is directed to a hand-held surface cleaning device that includes a relatively compact form-factor to allow users to store the same in a nearby location (e.g., in a drawer, in an associated charging dock, on a table top) for easy access to perform relatively small cleaning tasks that would otherwise require retrieving a full-size vacuum from storage. A hand-held surface cleaning device consistent with aspects of the present disclosure includes a body (or body portion) with a motor, power source and dust cup disposed therein. The body portion also functions as a handgrip to allow the hand-held surface cleaning device to be operated by one hand, for example.

A vacuum cleaner includes an upright handle assembly, a foot assembly adapted to be moved along a surface to be cleaned and having a suction nozzle, a multi-axis joint swivelably mounting the upright handle assembly to the foot assembly and defining a first axis about which the upright handle assembly twists relative to the foot assembly and a second axis about which the upright handle assembly pivot relative to the foot assembly, and a detachable vacuum module supported on the upright handle assembly by the module platform.
