Self-propelled underwater electromechanical apparatus for cleaning the bottom and walls of swimming pools

摘要: Self-propelled underwater electromechanical apparatus for cleaning the bottom and walls of swimming pools, comprising an electric motor (2) which operates, on one hand, a propeller turbine (3) circulating water and, other driving unit transmitting movement to roller travel system (R). At least said and/or are made with open structure inside swimming-pool freely circulates. The is brushless type both winding its rotor (22) that stator (25) embedded in impermeable resin. comprises reduction (4) output shaft (10) operating two systems mounted opposite sides apparatus. Movement reversal means, consisting extension (12) oscillating between different working positions, arranged systems.
