A brush device with quick couplings for cleaning elements (5) includes: first (15) and second (17) retaining elements that define respective cavities shaped approximately complementary to first (21) and second (23) matching members. The second the retaining element (17) has a tooth (27) delimiting the corresponding cavity, cantilevered onto a flexible arm (29) connecting it to a respective end of a first connection element (7) or of a second connection element (11). The flexible arm (29) has a driving extension (33) for manual actuation thereof to free the matching member (21, 23) from the tooth (27) allowing for the detachment of at least the second connection element (11) and of the cleaning element (5).

A head for an oral care implement comprises a number of colored filaments extending from a mounting surface of the head and being grouped together to define an initial color pattern. The colored filaments comprise at least a first and a second type of filament, wherein the types of filaments differ in color changing characteristics over a pre-defined period of time, the pre-defined period of time being the same for the first and the second type of filament so that the initial color pattern changes color characteristics over at least a first pre-defined period of time to a first color pattern, the first color pattern being different form the initial color pattern.

An electric toothbrush, in combination with a universal base for receiving and wirelessly charging the toothbrush, the base to be coupled with the electric toothbrush for wireless communication therebetween. The base comprises a magnetic element for forming a magnetic connection with the electric toothbrush when the latter is received by the base for charging. The base includes a charging component for inductively charging the electric toothbrush, a Bluetooth component for communicating usage data received from the toothbrush during a brushing session, an analyzing component for instantaneous processing of the usage data received from the toothbrush, a timer-clock component for displaying either a count-up or a countdown of the brushing session during the brushing session and time of day before and after the brushing session, and a multi-functional light component for instantaneously communicating, during the brushing session, at least one element of the usage data.

The present invention provides a cleaning unit, comprising: a columnar body part having a rotation guide opening formed on the outer circumferential surface thereof; a shaft installed to reciprocate a predetermined distance in the longitudinal direction thereof in a hollow formed in the body part; a drive part that protrudes from the shaft in the radial direction thereof; a brush part that has one side installed on the outer circumferential surface of the body part along the longitudinal direction thereof and rotates on the basis of the one side as a rotation axis; and a driven part that extends from the brush part toward the drive part, passes through the rotation guide opening, and is inserted into a rotation guide groove formed in the drive part. The rotation guide groove extends at a predetermined angle with respect to the longitudinal direction of the shaft, and as the shaft reciprocates, the driven part is guided to rotate by means of the rotation guide groove, and the brush is rotated by means of the rotation of the driven part. The cleaning unit may include a robot cleaner or a cleaner operated by means of a user's operation.

A cleaning head for a personal care appliance includes an elastic bladder having a bladder wall enclosing a fluid. The bladder wall has an inner base portion with a base thickness, which may be non-uniform, and a plurality of spaced projections extending outwardly from the inner base portion. The bladder is fixedly attached to a receiver portion of a bladder support, and a retainer is provided for attaching the bladder support to the personal care appliance such that the bladder support is drivably engaged by the personal care appliance. At least some of the plurality of spaced projections are configured to dynamically engage and disengage with neighboring ones of the plurality of spaced projections during use.

A cleaning system and method can include a leading carriage assembly attached to a brush assembly and can be configured to drive the brush assembly. A trailing carriage assembly can be configured to move along a track. The trailing carriage assembly can be attached to an arm. A vertical support rod can be partially disposed within the arm and can be attached to the brush assembly. A height of the vertical support rod can be positioned by one or more clamps located around the vertical support rod.
