A fluid flow actuated tool including a housing, a tool and an actuating mechanism. The housing includes a housing interior. The housing interior receives a flow of fluid. The actuating mechanism includes a fluid wheel structure. The fluid wheel structure is connected to the tool. At least a portion of the fluid wheel structure is arranged in the flow of fluid for rotating the fluid wheel structure. The tool is actuated based on rotation of the fluid wheel structure.

An apparatus for dispensing a brushable substance comprises a bracket and a sleeve, comprising an inner tubular sleeve wall and an outer tubular sleeve wall. The sleeve is coupled to the bracket and is rotatable relative to the bracket. The apparatus also comprises a cartridge, comprising an inner tubular cartridge wall and an outer tubular cartridge wall. The apparatus additionally comprises a valve, configured to be communicatively coupled with the cartridge, a brush-arm assembly, coupled to the sleeve a linear actuator to control flow of the brushable substance from the valve, an annular plunger, positioned between the inner tubular cartridge wall and the outer tubular cartridge wall, and a twist-lock pressure cap, configured to be hermetically coupled with the cartridge. The cartridge is configured to be positioned between the inner tubular sleeve wall and the outer tubular sleeve wall and between the twist-lock pressure cap and the valve.

An apparatus for treating a vehicle surface with a fluid has a rotation device pivotably mounted about an axis of rotation, and a fluid supply device disposed concentrically with respect to the rotation device and which has an inlet opening for the supply of fluid. The apparatus is characterized in that a groove is formed in the fluid supply device. The groove is fluidically connected to the inlet opening and extends in the circumferential direction with respect to the axis of rotation over a limited circumferential angle range of the fluid supply device. The rotation device has a plurality of separate fluid channels, each of which opens into openings. The openings are disposed such that irrespective of the angular position of the rotation device to the fluid supply device with respect to the axis of rotation, and at least one of the openings of the rotation device is fluidically connected to the groove of the fluid supply device.

A method of removing a tip from a body of an applicator, fixed to an end- effector, wherein the applicator comprises a coupler, releasably engageable with the tip to interlock the tip with the body of the applicator, is disclosed. The method comprises, with the coupler of the applicator releasably engaged with the tip, locating the end-effector so that a pawl is engaged with a third tooth on the tip to prevent movement of the tip in a fifth direction away from the pawl, and a wedge disengages the coupler of the applicator from the tip. The method also comprises, with the pawl engaged with the third tooth on the tip and the coupler of the applicator disengaged from the tip by the wedge, using the end-effector to move the body of the applicator in the fifth direction to disengage the tip from the body of the applicator.
