ABSTRACT:
A suction cleaning device which is used for cleaning a swimming pool includes a removable door to improve access to the housing interior. The suction cleaning device is of the type having a primary and a secondary fluid flow path. The primary flow path has a primary turbine positioned in it for driving the device. The steering mechanism is of the type which has two secondary turbines which work together and comprise the secondary flow paths. The secondary fluid outlets, from the secondary flow paths are located near the primary turbine such that the secondary flow path joins the primary flow path. Access to the primary turbine is necessary to remove larger pieces of debris. A removable door having an opening aligned with the primary fluid inlet provides for access to the primary turbine. A screen integral with the removable door is preferably provided to prevent the entry of back wash debris into the lower secondary flow path. Screen guides provide for ease of replacement of the removable door.
