Open the CIPO recordAbstract From the Canadian patent
A floor machine for stripping, washing or otherwise treating the surface of the floor with a rotating treatment disc such as a brush or a pad. A protective skirt over the pad is arranged to "float" i.e. to drop, freely over the disc with a view to minimizing the clearance between the floor and the skirt without detracting from the even ride of the disc over the floor.

Why it's free to use
- Filed January 26, 1994 and granted May 13, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 26, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 26, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
