End effectors and systems including end effectors including embedded batteries and auxiliary components powered by the batteries are described. In an example, the end effector includes a base portion coupleable to a motor carried by an appliance that is separate from the end effector; and a battery disposed in the base portion configured to power an auxiliary component of the end effector.

A hairbrush includes a bristle carrier including a surface and a plurality of first and second bristles fastened on the surface. The first bristles and the second bristles are arranged in rows and have a plurality of different configurations. In one embodiment, a bent member is formed on a top of each second bristle.

A method of whitening teeth. The method may include delivering a buffer solution from a reservoir of a toothbrush to one or more tooth cleaning elements of the toothbrush; applying a toothpaste containing a peroxide to the tooth cleaning elements, the toothpaste having a first pH; and brushing the teeth with the tooth cleaning elements, thereby mixing the buffer solution and the toothpaste to form, at surfaces of the teeth, a tooth whitening mixture having a second pH that is greater than the first pH.

An interdental cleaner has a rod-shaped support made of plastics material, which has a cleaning device in an axial end region, which cleaning device has a covering for the support made of a soft-elastic plastics material and a bristle set having a plurality of bristle bundles protruding, with a radial component, from the covering. The bristle bundles extend through the support and are embedded and held therein. The covering has at least one recess on its outer surface, wherein at least one of the bristle bundles is arranged within the recess.

A reconfigurable modular brush has a brush head including brush-head upper and lower surfaces extending longitudinally along a brush-head axis between brush-head first and second ends. Laterally opposed brush-head first and second sides extend between the brush-head upper and lower surfaces and longitudinally between the brush-head first and second ends. A bristle array is defined by a plurality of bristles protruding from the brush-head lower surface. A brush handle includes a grip portion and a brush-head mount, the brush handle having a lengthwise extent disposed generally along a handle axis between handle proximate and distal ends. The brush head and brush-head mount are cooperatively configured such that the handle can selectively capture and retain the brush head. Moreover, the longitudinal orientation in which the brush head is captured and retained by the brush handle is selectively reversible.

A brush tip for a cosmetic applicator which is hygienic by preventing the growth of bacteria and other germs in the area of the brush tip not impregnated with the application fluid, as well as the manufacturing method of the brush tip and a cosmetic applicator using the brush tip. This brush tip for a cosmetic applicator includes brush tip filaments and serving as an applying part of the cosmetic applicator having a cosmetic storage for storing a cosmetic fluid, with the rear end of the brush tip attached to the front end of the cosmetic storage. The brush tip incorporates a discharge port that communicates with the cosmetic storage of the cosmetic applicator, and a coating of an antimicrobial agent is formed on the surface of the brush tip filaments, located behind the discharge port inside the brush tip.
