A robotic cleaner may include an air inlet, a suction motor, the suction motor being fluidly coupled to the air inlet, and a first primary side brush configured to rotate about a first primary side brush rotation axis. The first primary side brush rotation axis may extend transverse to a surface to be cleaned at a first non-perpendicular angle.

A surface cleaning head with dual rotating agitators (e.g., a leading roller and a brush roll) may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The rotating brush roll may be located in the suction conduit with the leading roller located in front of and spaced from the brush roll, forming an inter-roller air passageway therebetween. The leading roller may provide a softer cleaning element than the brush roll and may also have an outside diameter that is less than the outside diameter of the brush roll. The surface cleaning head may also include debriding protrusions contacting the leading roller and/or a leading bumper that extends in front of the leading roller.

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.

A vacuum cleaner including a cleaner body including a motor configured to generate a suction force and a foreign substance collection chamber; and a suction head connected to the cleaner body. The suction head may include a drum brush, a one-way roller disposed in front of the drum brush, and a housing having a suction port. The drum brush and the one-way roller may be configured so that, when the suction head is moving forward on a surface to be cleaned, the drum brush and the one-way roller rotate so that foreign substances on the surface are suctioned by the suction force into the housing through the suction port to be guided to the foreign substance collection chamber, and when the suction head is moving rearward on the surface, rotation of the one-way roller is restricted to prevent the foreign substances suctioned into the housing from being discharged outside of the housing of the suction head through the suction port.

Provided is a robot including a chassis; a set of wheels coupled to the chassis; a plurality of sensors; a processor; and a tangible, non-transitory, machine readable medium storing instructions that when executed by the processor effectuates operations. The operations include capturing, with an image sensor disposed on the robot, a plurality of images of an environment of the robot as the robot navigates within the environment; identifying, with the processor, an obstacle type of an obstacle captured in an image based on a comparison between features of the obstacle and features of obstacles with different obstacles types stored in a database; and determining, with the processor, an action of the robot based on the obstacle type of the obstacle.

An autonomous traveling floor cleaner is disclosed that improves cleaning efficiency. A floor cleaner may include a suction nozzle that suctions suction matter collected by a rotary brush, an extension nozzle that suctions suction matter collected by an extension brush, and a collection box for collecting, through an inlet, the suction matter suctioned by the nozzles. The floor cleaner may have an elongated profile. The extension nozzle may be switchable between a retracted posture and a lateral cleaning posture. The extension nozzle in the lateral cleaning posture may be pivotable rearward. The extension nozzle in the lateral cleaning posture may have a protruding end in the width direction to be aligned with an end of a turning range of the floor cleaner in the width direction.

Systems and methods for navigating an autonomous vacuum are disclosed. According to one method, the autonomous vacuum traverses a cleaning environment having a plurality of surfaces. As the autonomous vacuum is traversing the cleaning environment, sensors on the autonomous vacuum capture sensor data describing a first section of a surface on which the autonomous vacuum is currently traversing. Based on the received sensor data, the autonomous vacuum can determine that the first section is of a first surface type of a plurality of surface types. The autonomous vacuum can generate a user interface with a background displaying the determined first surface type to notify the user of where the autonomous vacuum is cleaning.

A cleaning machine may include: a first brush comprising a first brush shaft extending in a left-right direction and a first brush body held by the first brush shaft; a second brush comprising a second brush shaft extending in the left-right direction and a second brush body held on the second brush shaft; a brush supporting member supporting each of the first brush and the second brush such that the first brush and the second brush are rotatable; a body supporting the brush supporting member such that the brush supporting member is pivotable; and a pivot mechanism configured to pivot the brush supporting member with respect to the body. At least the first brush may move with respect to the body in an up-down direction when the brush supporting member pivots with respect to the body.

A robotic cleaner may include one or more driven wheels, one or more environmental sensors, at least one of the one or more environmental sensors configured to detect a first obstacle having a first vertically extending surface, one or more edge cleaning implements, and a controller communicatively coupled to the one or more driven wheels and the one or more environmental sensors. In response to detecting the first obstacle, the controller may be configured to cause the robotic cleaner to move through a rotation angle such that at least one of the one or more edge cleaning implements approaches the first vertically extending surface.

A suction head of a vacuum cleaner including a housing having a suction port, a drum brush rotatably installed in the housing, a foreign substance removal pad provided on an inner surface of the housing to remove foreign substances wound on the drum brush by friction, and an anti-slip pad provided on the drum brush to prevent the foreign substances from slipping upon experiencing the friction with the foreign substance removal pad.
