ABSTRACT:
A mechanism is provided for dislodging a submersible cleaning device from a vertical wall after a predetermined time period on such wall. The mechanism includes an operating gear that engages when the cleaning device climbs the wall. Once engaged, the gear drives a cam mechanism which in turn engages a device for pushing the cleaner off the wall thereby breaking the suction of the cleaning device and causing the cleaning device to drop from the wall. A turning brush is used to break the suction but it will be appreciated that any lever or similar device can be employed.
