depths d 1 and d 2 respectfully where u201c d u201d generally represents the depth that the inlet extension member 30 extends below the exterior surface of the baseplate 20 the lesser depth of inlet extension member 34 raises the suction point of the cleaning apparatus closer to the baseplate 20 the use of an inlet extension member having lesser depth can be beneficial in situations where for example obstacles project higher from the surface to be cleaned and would otherwise immobilize or significantly divert the pool cleaner from its intended programmed movement pattern by contacting the rim of the inlet extension member referring now to fig6 there is shown a cross sectional view of the inlet extension member 32 viewed along the section line 6 6 of fig3 the extension member 32 or 34 is removable from the baseplate 20 and includes at least one wall 40 having an outer surface 42 and inner surface 43 where the outer surface 42 is configured to correspond in size and shape to the baseplate water inlet opening 24 formed through the baseplate 20 of the pool cleaner 10 the inner surface 43 of the at least one wall 40 defines an extended inlet for drawing the pool water through the baseplate inlet extension member 32 the at least one wall.
