the invention relates to a brush , especially a toilet brush , comprising a brush head and a brush head holder , wherein the brush head can be detachably mounted on the brush head holder , especially in such a way that the two interlock . according to the invention , the brush head can be slid onto the brush head holder with a friction fit . it is therefore possible to exchange a used brush head for a new , germ - free replacement . this not only avoids the unattractive appearance that conventional brushes acquire after repeated use , but also prevents health risks to the user .
