An electric motor is coupled to at least one of said water pump, the rotationally-mounted elements and the rotary brush. The pool cleaner is configured to continue climbing upward on a pool wall and tell the rotary brush assembly is above the water level and climbs over the pool coping edge propelling said pool cleaner onto the pool deck.

A pump toothbrush having a toothpaste tube to dispense dentifrice material to top of bristle head is disclosed. The pump toothbrush has a pump head with a resilient button to create an internal vacuum force to draw the dentifrice material from the toothpaste tube. The toothpaste tube is supported by width-limiting fingers to prevent total collapsing of sidewalls resulting in blocking of its flow channel. A self-closing spout is used for preventing backflow. For a manual pump toothbrush the toothpaste tube has an oval-shaped shoulder for mating with the oval-shaped shoulder of a detachable handle for fastening the toothpaste tube by threads. For an electrical pump toothbrush, a detachable endcap connector is used for swinging out the toothpaste tube from its handle for replacement. A sonic vibration model uses rubber molding to minimize vibration on the handle. A dual-rotary model has two rotary bristle elements engaged by gear teeth.

A device for cleaning interdental spaces includes a housing that forms a handle. The device also includes a brush holder for holding an interdental brush, and a drive device which is configured to generate rotational and translational movement of the brush holder and/or of an interdental brush held in the brush holder.

Provided is an automatic control type electric toothbrush, comprising a toothbrush head (20) and a toothbrush handle (10) connected by means of a driving shaft (12), wherein the toothbrush handle (10) is provided with a gesture sensor, a control module and a driving mechanism; and the control module can control the driving mechanism to drive the driving shaft (12), and same also drives the toothbrush head (20) to rotate clockwise or anticlockwise according to gesture data acquired from the gesture sensor, so that the toothbrush head (20) rotates in the direction from teeth root to dental crown. The automatic control type electric toothbrush can realize the purpose of automatically brushing teeth along the teeth, and can protect the gingivae, thus achieving automated treatment without manual control by a user, and therefore improving user experience.

An electric toothbrush having a head part with a rotating working element is described in detail. The electric toothbrush is equipped with elements configured and arranged to cooperate in driving the working element and to change the direction of its rotating movement.

A personal hygiene device has a drive unit having a support, a stator fixedly mounted at the support, and an armature spring-mounted at the support for driven linear oscillating motion along a first longitudinal direction parallel to or coinciding with an x-axis of an x-y-z coordinate system. The armature has a center of gravity located in rest at a coordinate [x.sub.a, y.sub.a, z.sub.a], and a drive shaft fixedly coupled with the armature and having a center of gravity located in rest at a coordinate [x.sub.d, y.sub.d, z.sub.d]. A first treatment head assembly, detachably connected to the drive shaft, has a center of gravity located in rest at a coordinate [x.sub.t1, y.sub.t1, z.sub.t1]. A secondary mass element, spring-mounted at the support for essentially linear oscillating motion along the first longitudinal direction, has a center of gravity located in rest at a coordinate [x.sub.m, y.sub.m, z.sub.m]. At least the coordinate [x.sub.a, y.sub.a, z.sub.a] of the center of gravity of the armature has an offset in at least one of the y-direction and z-direction with respect to the coordinate [x.sub.d, y.sub.d, z.sub.d] of the center of gravity of the drive-shaft or with respect to the coordinate [x.sub.t1, y.sub.t1, z.sub.t1] of the center of gravity of the first treatment head assembly, i.e., y.sub.a≠y.sub.d and/or y.sub.a≠y.sub.t1 and/or z.sub.a≠z.sub.d and/or z.sub.a≠z.sub.t1; and the secondary mass element is configured such that the coordinate [x.sub.m, y.sub.m, z.sub.m] of the center of gravity of the secondary mass element is aligned with the coordinate [x.sub.j, y.sub.j, z.sub.j] of the joint center of gravity of the drive shaft, the first treatment head assembly and the armature in the at least one offset direction, i.e., y.sub.m=y.sub.j and z.sub.m=z.sub.j, so that a line connecting the coordinate [x.sub.m, y.sub.m, z.sub.m] of the center of gravity of the secondary mass element and the coordinate [x.sub.j, y.sub.jz.sub.j] of the joint center of gravity is parallel to or coincides with the x-axis.
