Open the CIPO recordAbstract From the Canadian patent
A hand held cleaner is provided with a swiveling nozzle that moves from a position perpendicular to the cleaner body to a position of axial alignment with it. A series of stops are mounted on the swiveling nozzle and cleaner body to limit nozzle swing to these two positions. A reciprocal latch is mounted with the nozzle to engage selectively, in one of, a pair of latching apertures in the cleaner body to lockingly maintain the swiveling nozzle of its stopped positions. The agitator and agitator belt are offset from what would be considered their normal centered relationship to accommodate the swiveling action of the hand held cleaner nozzle.

Why it's free to use
- Filed September 13, 1996 and granted September 28, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 13, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 13, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
