Cleaning utensil

A cleaning utensil comprising:

• an elongated hollow handle having a longitudinal axis and a grip end and a head end,
• the handle defining a chamber therein, and
• first coupling structure on the head end;
• and
• a replaceable head including a rigid hollow core having a handle end and a working end,
• the core defining a cavity therein,
• second coupling structure on the handle end of the core adapted for engagement with the first coupling structure to mount the core on the handle in a use condition with the cavity communicating with the chamber to define a fluid reservoir,
• a flexible, resilient, porous, absorbent cleaning medium mounted on the core and covering the core except for the second coupling structure, and
• an orifice in the working end of the core providing communication between the reservoir and the cleaning medium.
