The double action cleaning tool of the present invention includes a dynamic double action dual brush head and a handle. The dynamic double action dual brush head includes two brush heads rotatably attached to a brush head base, allowing the brush heads to independently rotate about the axis in which it is rotatably attached to the brush head base. A mechanical device capable of storing and releasing energy is connected between the two brush heads, which is rigidly attached to the brush head base. The double action cleaning tool stores energy in the form of potential energy in the mechanical energy storage device of the dynamic double action dual brush head during the sweeping stroke of the double action push broom. At the end of the sweeping stroke, the stored potential energy is converted into kinetic energy and rotates the dual brush, thereby providing an additional sweeping motion.

A swiveling brush for the application of fluid products, for example, a powdery product, a creamy product, a liquid product or the like. The swiveling brush comprising a gripping portion intended to be grasped by a hand of a user for the movement of the brush; and an housing seat formed on the gripping portion and intended to house an application body comprising, in turn, a plurality of spreading elements which are adapted to take and apply a fluid product on a work surface. The application body is associated with the housing seat by interposition of coupling structure/unit/component/device (or the like) configured to allow the rotation of the application body with respect to the gripping portion.

A toothbrush (10) includes a brush assembly (16) with at least three bristle arrangements (12), each having opposing inwardly-directed bristles (122, 124, 126) for simultaneously contacting facial and lingual surfaces (52, 54), and preferably also occlusal surfaces (56) of the teeth (50). Flexible linkages (14), interconnecting the bristle arrangements (12), maintain a relative spacing between the bristle arrangements (12) while allowing variation of an effective curvature of the brush assembly (16) such that the bristle arrangements (12) can ride along, and conform to a non-uniform curvature of, the arch of teeth. The toothbrush (IO) preferably also includes an actuation mechanism (22) for generating to-and-fro motion of the brush assembly (16) along the arch of teeth, most preferably combined with a more rapid small-amplitude oscillatory motion.

A makeup brush includes a housing having a longitudinal axis, and a drive assembly provided within the housing. The drive assembly includes a stator assembly and an armature assembly adjacent the stator assembly, the armature assembly including a mounting member held by the housing and a pivot arm member pivotably coupled to the mounting member, the pivot arm member being structured to pivot with respect to the mounting member about an axis that is parallel to the longitudinal axis, wherein the stator, when energized, is structured to cause the pivot arm member to pivot with respect to the mounting member. The makeup brush also includes a brush head member having a plurality of bristles and being coupled to the pivot arm member such that pivoting movement of the pivot member causes the brush head member to oscillate relative to the housing.

The invention relates to an apparatus for cleaning. The apparatus comprises a cleaning member adapted to engage a surface to be cleaned; a support member for supporting the cleaning member, with the cleaning member being resiliently movable between an extended position and a retracted position relative to the support member in response to an external force applied to the cleaning member; one or more engaging members provided at the support member; wherein the engaging members are adapted to engage the surface when the cleaning member is arranged at the retracted position such that further retraction of the cleaning member is substantially prevented.
