Abstract: This invention provides a guiding apparatus 10 for use in operating a pool cleaner. The apparatus 10 includes a housing configured for connection to a hose of the pool cleaner. The housing has front and rear parts 12, 14 configured to pivot in relation to each other about a zone of contact between the front and rear parts 12, 14. The apparatus 10 also includes a driven member having a ratchet 20 and an arm 22 housed within the housing and arranged to be driven by the to and fro motion of the hose. The apparatus 10 further includes a transducer housed within the housing, connected to the driven member, and adapted to transduce motion of the driven member to motion to be imparted to pivot the front and rear parts 12, 14 in relation to each other in order to influence movement of the body of the pool cleaner.

Abstract: The installation disclosed comprises a body of water, a pump, a filter and pipes connecting the body of water, pump and filter. Additional pipes lead from the pipe to the return pipe and to waste. Solenoid operated valves are provided in the pipes so that flow through these pipes can be permitted or prevented depending on whether the valves are open or closed. A pressure sensor detects pressure at the inlet of the filter. A programmable controller controls operation of the valves all of which can be operated independently of the others. The body of water will normally be a swimming pool but could be a tank in which aquatic creatures are grown.
