A cleaning implement is provided for cleaning surfaces with a cleaning substrate. The cleaning implement includes a handle connected via a universal joint to a mop head. A portion of the universal joint forms a handgrip which allows a user to hold the mop head independently from the handle. The cleaning implement has a quick- disconnect mechanism which includes a male element located at a distal end of the handle and a female element located on the universal joint and which allow a user to easily disconnect the handle from the mop head.

Why it's free to use
- Filed September 3, 2004 and granted June 7, 2016. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 3, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 3, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
