Back-scrubbing device

Abstract

A back-scrubbing device has a resilient body, wherein the body has a front surface, a rear surface and multiple sucking discs. The front surface has a ridge and two concavities. The rear surface has multiple disc holes. Each disc hole has an inner edge and a holding member and respectively holds one of the multiple sucking discs. Each of the multiple sucking discs has a sucking surface, a disc-rear surface and a threaded shaft. The disc-rear surface contacts the inner edge of one of the disc holes. The threaded shaft is held in one of the disc holes. The back-scrubbing device is attached to a wall of a bathroom for washing a back of a user when he or she is taking a shower or having a bath.
