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.

A portable cleaning device with interchangeable cleaning tools and an alert system may include an elongate rod having a first end and a second end, a handle attached to the first end of the rod, a cleaning attachment removably engaged with the second end of the rod, a handle grip sensor operatively attached to the handle and a cleaning attachment pressure sensor operatively attached to the cleaning attachment, and an indicator operatively attached to each sensor, the indicator designed to alert a user when the sensor is activated.

A pet dental device includes a main body and an outer shell. The main body houses a pressure-actuated sound generator and that has outer surfaces from which a plurality of brushes extend. The outer shell covers at least a portion of the main body such that a gap exists between the shell and the outer surfaces of the main body, and includes a plurality of brush ports aligned with the brushes. The outer shell is sufficiently flexible to be compressed inward by a selected animal's jaws such that toothpaste is distributed via the brushes to teeth of the selected animal and such that sounds are generated, via the pressure-actuated sound generator housed in the main body, more or less simultaneously with the distribution of toothpaste.

A brush includes a head with bristles, an actuator that expands and contracts in accordance with an electric signal, a connection member that transmits vibration of the actuator to the head, and a body including a housing that houses the actuator. The direction of reciprocal vibration of the head is at a predetermined angle relative to the direction of extension of the housing.

This disclosure presents systems and methods to improve user brushing behavior. Exemplary implementations may: effectuate presentation of audio content via an audio output device, the audio content being characterized by an audio profile; obtain output signals from one or more sensors coupled to a user device, the output signals conveying user input information, the user input information defining user input by a user via the user device; determine, based on the user input information, a user profile, the user profile including one or more user values of the one or more audio attribute; compare the user profile with the audio profile to determine, for individual audio attributes, one or more differences; determine one or more scores reflecting the one or more differences; and/or perform other operations.

An oral care implement including a handle and an oral care refill head. The handle has a gripping portion, an engagement component coupled to a distal end of the gripping portion, and a stem. The engagement component includes a plate portion and a first engagement feature. The stem extends through an opening in the engagement component and protrudes from the plate portion. The oral care refill head includes an oral care treatment portion and a sleeve portion. The sleeve portion has an inner surface that defines a sleeve cavity having a cavity axis and a second engagement feature. When the oral care refill head is detachably coupled to the handle, the first and second engagement features mate with one another to at least one of: (1) position the oral care refill head and the handle in an operational alignment; and (2) lock the oral care refill head to the handle.

A method for controlling display of a user interface for optimizing performance in using a personal care appliance is provided including: receiving a user info or regimen; receiving a protocol or routine to use the appliance; receiving an appliance status related to a user's usage of the appliance; comparing the appliance status to a target usage of the appliance in the protocol or routine; and controlling display of an indicator of the user's performance based on the comparison.

A personal care appliance is provided that includes a brushhead for use in skincare; an appliance body having a motor assembly for oscillating the brushhead, wherein the brushhead or a portion of the motor assembly that is configured to oscillate includes a marking; and a brush encoder configured to detect the marking, and determine the oscillation of the brushhead.

A system to promote optimum performance of a personal care appliance is provided including: a personal care appliance having an appliance status; and a client device, in communication with the appliance, including circuitry configured to compare the appliance status with the protocol for using the appliance, control display of an indicator based on the comparison.
