A device for attaching and detaching a toothbrush head and a toothbrush kit includes a first housing; a second housing and a third housing pivotally mounted to the first housing on opposite sides of the first housing respectively; and a lining component disposed in the first housing; a head attaching cavity formed in a side of the lining component facing the second housing, a step formed on an inner wall of the head attaching cavity, a pressing portion formed on a surface of the second housing facing the lining component; and a head detaching cavity formed in a side of the lining component facing the third housing, a step formed on the inner wall of the head detaching cavity, a pushing post formed on the surface of the third housing facing the lining component.

An autonomous cleaning robot includes a drive system to move the autonomous cleaning robot about a floor surface, a cleaning head on a bottom portion of the autonomous cleaning robot, a side brush on the bottom portion of the autonomous cleaning robot, and a vacuum system in pneumatic communication with the opening. The cleaning head is configured to direct debris from the floor surface into the autonomous cleaning robot as the autonomous cleaning robot moves about the floor surface. The side brush is rotatable about a rotational axis forming a non-zero angle with a floor surface, and the side brush comprising an opening.

A system is disclosed that includes a server, which includes a network interface configured to receive an order request for one or more ordered products from an end device. The order request includes user identification information, product identification information, and time interval information. The system further includes a memory and a processor configured to access the memory and operate according to computer program code. The computer program code includes product code, product status code, which causes the processor to acquire a first status (product location) and a second status (condition state) of one of the one or more ordered products. The computer program code further includes product transport code configured to cause the processor to determine a transport location based on the acquired information, and generate an instruction to send the one of the one or more ordered products to a storage facility, a reconditioning facility, or a user.

Several hairstyling tools are described. One styling tool includes a removable cover and a main body with a spatula located at one end of the main body. An edge-defining brush is located at the other end of the main body. The spatula end is received by the removable cover while not in use. Another tool includes a main body with a tool section and a handle section. Amongst other features, the tool section includes a comb and a plurality of brushes.

An oral care system that includes an oral care implement and a tracking attachment. The oral care implement may include a handle and a head. The tracking attachment is detachably coupled to the oral care implement. The tracking attachment may include a housing including a first housing portion having an inner surface that defines a first cavity and a second housing portion having an inner surface that defines a second cavity. The tracking attachment may also include a tracking unit configured to facilitate tracking at least one of a position, orientation, or movement of the oral care implement to which it is attached. A first portion of the handle may be positioned within the first cavity and a second portion of the handle may be positioned within the second cavity.

An oral care device comprises a head portion and a handle portion. The head portion comprises at least one supporting arm and a base. The supporting arm extends from the base. A sensor is exposed from the supporting arm. The handle portion is configured to move relative to the head portion. The handle portion comprises a processor, wherein the processor is configured to receive signals from the sensor and analyze the signals received from the sensor.

The present invention offers a halo-illuminating light pattern for clearly showing areas of a pet's fur to the user performing brushing. Such a halo-illuminating light pattern provides a full, 360-degree light pattern of the pet's fur. This eliminates the necessity for using an additional light source, for example a flashlight or being made to settle on a light source that only highlights one side of a pet's fur, leaving another side in shadow.

A brushroll for a surface cleaning apparatus includes a brush dowel defining a central rotational axis which extends longitudinally through the brush dowel. The brush dowel includes bristle supports, sweeper supports, and a shroud surface extending between the bristle supports and the sweeper supports. A plurality of bristles protrude from the bristle supports.

A vacuuming broom assembly includes a vacuum pack that is wearable on a user's back. The vacuum pack has an intake for urging air inwardly therein when the vacuum pack is turned on and a suction hose is fluidly coupled to the intake. A broom is provided that has a head and a handle. A suction manifold is coupled to the broom and the suction manifold has a pair of inlet ports and an exhaust port. The suction hose is fluidly coupled to the exhaust port such that the suction manifold is in fluid communication with the vacuum unit. Each of the inlet ports is aligned with the head of the broom for sucking up debris that is produced from sweeping. In this way the vacuum unit reduces airborne particles produced from sweeping.
