An oral irrigator having an irrigator tip, the tip including a handle portion, a tip portion, a channel in fluid communication with the tether and arranged within the handle portion and the tip portion, and an actuator located on or within the handle portion, the actuator arranged to at least partially altar a flow of a fluid through the channel. The oral irrigator further includes a housing, the housing having a reservoir in fluid communication with a pump sub-assembly, a sensor arranged to measure a first pressure or first electrical load within the pump sub-assembly, and a control unit arranged to control an operational current provided to the pump sub-assembly where operation of the actuator produces a second pressure or electrical load measured by the sensor and the control unit is arranged to alter the operational current of the motor in response to the change.

A cleaning device, for cleaning a surface, includes a nozzle arrangement. The nozzle arrangement includes a brush compartment surrounded by a brush. The brush includes brush elements including tip portions for contacting the surface to be cleaned and picking up dirt particles and/or liquid from the surface during rotation of the brush. The nozzle arrangement further includes a bouncing element with position adjusted relative to the surface and depending on a direction of movement of the cleaning device. The bouncing element is arranged in a first position and at a first distance dto the surface, when the cleaning device is moved in a forward direction and in a second position and at a second distance dto the surface, when the cleaning device is moved in an opposite backward direction, such that dis greater than d

A semi-free rotating crankshaft actuator () for an oral healthcare appliance comprises a chamber (), a spring loadable plunger (), and a crank mechanism (). The crank mechanism () comprises at least a drive pin () rotatably driven about a drive axis (), and a crank shaft () semi-freely rotatable about the drive axis, wherein the crank shaft () couples to the spring loadable plunger () and is partially driven about the drive axis () via (i) the drive pin () in a first operational mode, (ii) the spring loadable plunger () in a second operational mode, and (iii) the drive pin () in a third operational mode that comprises at least completing an incomplete actuation of the plunger () from an undesired end position to the desired end position in response to the crank shaft () pushing the plunger () from the undesired end position to the desired end position.
