20230329512 · 2023-10-19 ·

A debris collection base and a cleaning system. The debris collection base includes: a body including a first splicing end, a debris collection cavity spaced apart from the first splicing end, and a debris collection channel extending from the first splicing end to be in communication with the debris collection cavity; and a bearing seat module used for bearing a cleaning robot and including a second splicing end, a debris collection opening spaced apart from the second splicing end, and a debris inlet channel extending from the second splicing end to be in communication with the debris collection opening, the second splicing end being capable of being spliced with the first splicing end or separated from the first splicing end, and the debris inlet channel being in hermetical communication with the debris collection channel when the first splicing end is spliced with the second splicing end.

Control of evacuation stations

An evacuation station for collecting debris from a cleaning robot includes a controller configured to execute instructions to perform one or more operations. The one or more operations includes initiating an evacuation operation such that an air mover draws air containing debris from the cleaning robot, through an intake of the evacuation station, and through a canister of the evacuation station and such that a receptacle received by the evacuation station receives at least a portion of the debris drawn from the cleaning robot. The one or more operations includes ceasing the evacuation operation in response to a pressure value being within a range. The pressure value is determined based at least in part on data indicative of an air pressure, and the range is set based at least in part on a number of evacuation operations initiated before the evacuation operation.

Filter assembly and floor cleaner
11772023 · 2023-10-03 · ·

The present disclosure provides a floor cleaner that includes a replaceable component, such as a filter. The floor cleaner has a detection mechanism comprising a magnet on the replaceable component and a Hall Effect sensor positioned to detect the permanent magnet when the replaceable component is correctly installed on the floor cleaner. Operation of one or more electrically-powered components of the floor cleaner is prevented when the permanent magnet is not detected by the Hall Effect sensor.

Handheld sweeper with rotating bristles for removing hair and fur from surfaces
11771289 · 2023-10-03 ·

A cleaning implement which utilizes a low-power motor coupled to a plurality of angle gears and drive lines for creating a mechanical action adapted to clean hair and fur. The device includes a housing, which may be bifurcated, and a plurality of bristled protrusions positioned in staggered form along elongated shafts connected to drive lines using angle gears.

Vacuum cleaning apparatus

A vacuum cleaner includes a driving wheel, a cleaning part, a dust-collecting unit, a dust collection amount detection part, and a travel control part. The dust collection amount detection part detects the amount of the dust and dirt accumulated in the dust-collecting unit. The travel control part controls the driving of the driving wheel to make the vacuum cleaner travel autonomously. The travel control part makes the vacuum cleaner travel to a dust station in the case the amount of the dust and dirt detected by the dust collection amount detection part is equal to or more than a specified amount while the cleaning part performs cleaning. The travel control part further makes the vacuum cleaner undock from the dust station to restart the cleaning after the dust and dirt accumulated in the dust-collecting unit is transferred to a dust-collecting container at the dust station. The vacuum cleaning apparatus can adopt a downsized vacuum cleaner while ensuring convenience.

Cleaning robot

A cleaning robot includes a machine body, a rotating component, and a cover. The machine body defines a mounting groove. The rotating component includes an outer wall, and at least a part of the outer wall is jointed with the mounting groove to form a rotating pair. The cover is fixedly connected with the rotating component, and the cover is capable of cooperating with the machine body in an opening and closing manner.

Evacuation station system
11641988 · 2023-05-09 · ·

A cleaning system includes a robotic cleaner and an evacuation station. The robotic cleaner can dock with the evacuation station to have debris evacuated by the evacuation station. The robotic cleaner includes a bin to store debris, and the bin includes a port door through which the debris can be evacuated into the evacuation station. The evacuation station includes a vacuum motor to evacuate the bin of the robotic cleaner.

Maintenance Base Station

Provided is a maintenance base station, including a bin body, a rotatable cover, and a revolving shaft, wherein the rotatable cover is in rotatable connection with the bin body via the revolving shaft, the bin body has a debris collection chamber and a opening in communication with the debris collection chamber, the rotatable cover is configured for blocking or revealing the opening; and partial bin wall of the bin body adjacent to the opening is stretched towards the inner side or the outer side of the bin body, hereby forming an avoidance area, and the revolving shaft is arranged in the avoidance area, such that the revolving shaft and the bin wall are spaced apart from each other along the wall thickness direction of the bin wall, so as to accordingly limit the intervention of the revolving shaft in the wall thickness of the bin wall.

EVACUATION STATION

A mobile robot includes a body configured to traverse a surface and to receive debris from the surface, and a debris bin within the body. The debris bin includes a chamber to hold the debris received by the mobile robot, an exhaust port through which the debris exits the debris bin; and a door unit over the exhaust port. The door unit includes a flap configured to move, in response to air pressure at the exhaust port, between a closed position to cover the exhaust port and an open position to open a path between the chamber and the exhaust port. The door unit, including the flap in the open position and in the closed position, is within an exterior surface of the mobile robot.
