A cleaning robot includes a top cover, a bottom cover provided below the top cover, traveling parts provided in the bottom cover, a suction module provided in the bottom cover to suck in foreign materials on the ground, a recessed part firmed to be recessed inward between the top cover and the bottom cover, and a first sensor located in the recessed part.

A vacuum cleaner attachment is disclosed having a concave vacuum head with a swivel joint that permits swiveling of the vacuum head only within the plane of the vacuum head. The concave vacuum head can have a curvature that is similar to the curvature of a cylindrical surface to be vacuumed. Thus, while a user manipulates the conduit providing the air suction to the vacuum head, the concave surface can be supported and swiveled around the circumference of the cylindrical surface to be vacuumed, while the vacuum head is also moved along the length of the cylindrical surface. Throughout this movement of the concave vacuum head, the concave opening of the concave vacuum head can stay in closer proximity and conformity to the cylindrical surface than is possible using a fixed vacuum head with a flat opening, thereby making cleaning of the cylindrical surface more effective and efficient.

The present disclosure relates to a cleaner improving the cleaning efficiency. The cleaner includes a main body, a suction device configured to suck foreign substances on a surface to be cleaned, and an extension member positioned in the rear of the suction device to connect the main body and the suction device, wherein the suction device includes a suction head including a suction port, a connection member connecting the suction head and the extension member, and a weight accommodated in the suction device and disposed between the suction port and the extension member such that the suction port is prevented from being lifted from the surface to be cleaned when the suction device moves along the surface to be cleaned.

A suction accessory device is provided, for the connection with a suction apparatus or vacuum cleaner, for the collection of waste in places of difficult access and/or in delicate objects. The suction accessory device comprises a flexible and lightweight hose. At one end, the hose includes a reducing coupling adapter terminal for connecting to a vacuum cleaner or suction device. At the opposite end, the hose includes a nozzle connection terminal that is coupled to a first end of a flexible or rigid, handle or brush tube. At a second end of the brush tube, the brush tube includes a head connection terminal which connects to interchangeable suction heads or nozzles.

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 vacuum attachment for removing hair and/or fibrous debris from a crevice or surface being cleaned is disclosed herein. The vacuum attachment includes an attachment body portion, a first end of the attachment body portion configured to be connected to a vacuum hose, and the attachment body portion defining an air intake aperture at a second end of the attachment body portion; and an elongated rod disposed across a portion of the air intake aperture at the second end of the attachment body portion, the elongated rod including a plurality of protruding elements projecting outwardly from the elongated rod, the plurality of protruding elements being disposed at least partially around a periphery of the elongated rod and along at least a portion of a length of the elongated rod between the first end and the second end. A manual brush for removing hair and/or fibrous debris is also disclosed herein.

A cleaning head for a floor cleaner including a housing, a brushroll, a suction inlet, and a mounting plate. The mounting plate includes an edge brush adjacent the suction inlet and extending to a lateral side of the housing. The edge brush is configured to direct dirt and debris from the lateral side of the floor cleaner to the suction inlet.

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.
