The brush sleeve includes a generally cylindrical configuration cooperatively sized to accommodate a user's finger therein. One or more brush components suitable to scrub or clean a finger are disposed on the inside of the brush sleeve. Furthermore, the body, and in particular, a drive assembly is structure to cooperatively engage the brush sleeve and rotationally drive the brush sleeve via selective activation of a switch or activation assembly. Moreover, the drive assembly is configured to rotationally drive the brush sleeve in alternating rotational directions via successive activations. ## Claims ### Claim 1 A finger scrubber, comprising: a brush sleeve and a body, said brush sleeve comprising an at least partially open end and an oppositely disposed closed end defining an interior portion there between, at least one brush component disposed within said interior portion of said brush sleeve, said body comprising a sleeve housing and a drive assembly, said brush sleeve being coaxially and removably disposed within said sleeve housing, said drive assembly being structured engage said brush sleeve and at least temporarily drive said brush sleeve in a rotational manner within said sleeve housing, and an activation assembly engaged by said brush sleeve for selectively activating said drive assembly. ### Claim 2 (depends on 1) The finger scrubber as recited in claim 1 wherein said brush sleeve is disposed in alternating rotational directions within said sleeve housing via successive activations of said drive assembly. ### Claim 3 (depends on 1) The finger scrubber as recited in claim 1 wherein said activation assembly comprises a contact switch; said drive assembly being activated and said brush sleeve being rotationally driven within said brush housing while said contact switch is activated. ### Claim 4 (depends on 1) The finger scrubber as recited in claim 1 wherein said drive assembly comprises a rotational drive mechanism disposed within said brush housing; said brush sleeve comprising a drive engagement portion cooperatively configured to engage said rotational drive mechanism. ### Claim 5 (depends on 4) The finger scrubber as recited in claim 4 wherein said drive engagement portion comprises a recessed portion disposed on said closed end of said brush sleeve. ### Claim 6 (depends on 5) The finger scrubber as recited in claim 5 wherein said brush sleeve is rotationally driven within said sleeve housing via a cooperative engagement between said drive engagement portion of said brush sleeve and said rotational drive mechanism of said drive assembly. ### Claim 7 (depends on 6) The finger scrubber as recited in claim 6 wherein said drive assembly is structured to dispose said brush sleeve is alternating rotational directions within said sleeve housing via successive activations of said drive assembly. ### Claim 8 (depends on 1) The finger scrubber as recited in claim 1 wherein said at least one brush component is cooperatively and removably engaged to an interior wall of said brush sleeve. ### Claim 9 (depends on 8) The finger scrubber as recited in claim 8 wherein said brush sleeve comprises at least one retention channel disposed on said interior wall within said interior portion; said at least one brush component comprising a base at least partially disposed within said at least one retention channel. ### Claim 10 (depends on 9) The finger scrubber as recited in claim 9 wherein said at least one retention channel extends substantially along the length of said brush sleeve between said at least partially open end and said oppositely disposed closed end. ### Claim 11 An electrically driven finger scrubber, comprising: a cylindrical brush sleeve and a body, said cylindrical brush sleeve comprising an at least partially open proximal end and an oppositely disposed distal end defining an interior portion there between, at least one brush component disposed within said interior portion of said brush sleeve, said body comprising a cylindrical sleeve housing and a drive assembly, said cylindrical brush sleeve being coaxially disposed within said cylindrical sleeve housing, an activation assembly selectively engaged by said cylindrical brush sleeve for activating said drive assembly, said drive assembly being structured to engage said cylindrical brush sleeve and at least temporarily drive said cylindrical brush sleeve in a rotational manner about a longitudinal axis, and wherein said drive assembly is structured to drive said brush sleeve in alternating rotational directions with each successive selective engagement of said activation assembly. ### Claim 12 (depends on 11) The finger scrubber as recited in claim 11 wherein said activation assembly is activated via pressure exerted on said activation assembly from said cylindrical brush sleeve. ### Claim 13 (depends on 12) The finger scrubber as recited in claim 12 wherein said activation assembly comprises a plunger disposed within said cylindrical sleeve housing and selectively engaged between said cylindrical brush sleeve and a contact switch. ### Claim 14 (depends on 11) The finger scrubber as recited in claim 11 wherein said at least one brush component is cooperatively and removably engaged to an interior wall of said cylindrical brush sleeve. ### Claim 15 (depends on 14) The finger scrubber as recited in claim 14 wherein said cylindrical brush sleeve comprises at least one retention channel disposed on said interior wall within said interior portion; said at least one brush component comprising a base at least partially disposed within said at least one retention channel.
