  • Wheeled suction cleaners
    Patent number: 4560418
    Abstract: A wheeled suction cleaner with endless tracks is driven by a turbine actuated by water flowing through the cleaner. To enable the cleaner to be steered, the turbine also drives an eccentric mass which momentarily lessens the adhesion of the cleaner to the surface on which it works. Steering is effected by a motor also driven by water flowing through the device which intermittently and at intervals turns a spigot on the cleaner which is connected to a flexible suction hose.

  • Suction cleaners
    Patent number: 4536908
    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.
