Abstract
A suction cleaner for a swimming pool is supported on a bogie with inclined supporting feet resiliently biased. The bogie is rocked by means of a turbine through which water is pulled by suction to cause the bogie and hence the cleaner to move. To cause the cleaner to change direction another turbine intermittently drives a hose connection at the top of the cleaner in opposite directions with long periods of dwell in between.
Claims6
A suction cleaner head for use on a submerged surface comprising:
- a turbine housing,
- a suction inlet in the base of the housing,
- a shaft journalled in the housing,
- a turbine mounted on the shaft,
- a pair of rockers for supporting the housing at least partially on a surface, each rocker being pivoted to the housing,
- a pair of eccentrics on the turbine shaft, each eccentric being engaged with one of said rockers for providing a rocking action to a rocker,
- a pair of spaced apart friction feet pivoted to the underside of each rocker for contacting the surface,
- means for resiliently biasing each of said feet to an inclination so that each of said feet can perform a limited rocking motion relatively to the rocker when forces directed towards the surface are applied to the rocker, and an outlet from the housing adapted to be connected to a flexible hose.
