Claim:
A brushhead assembly attachment system for a personal care appliance which includes an appliance body, comprising: a hub member adapted to be secured to a driven shaft of a personal care appliance, the hub member including a plurality of locking elements around the periphery thereof; an outer brushhead portion having a first cleaning member extending therefrom, the outer brushhead portion having a connecting structure for removably joining the outer brushhead assembly to the personal care appliance; and an inner brushhead portion having a second cleaning member extending therefrom, configured to fit within the outer brushhead portion, which is configured to encircle the inner brushhead portion, wherein the inner brushhead portion includes a plurality of depending legs, at least some of which mate with the locking elements on the hub member, such that oscillating movement of the hub member results in similar movement of the inner brushhead portion, wherein at least others of the depending legs are configured to removably latch onto a portion of the outer brushhead portion, providing a joining relationship therebetween, but permitting oscillation of the inner brushhead portion relative to the outer brushhead portion, wherein the inner brushhead portion and the outer brushhead portion are configured relative to each other and to the hub member such that attaching the outer brushhead portion to the appliance body by means of said connecting structure results in both connection of the outer brushhead portion to the appliance body and connection of the inner brushhead portion to the hub member.
