TRANSLATABLE SUCTION CLEANING VEHICLE
First Claim
1. A translatable suction cleaning vehicle adapted to movably interface with a bottom surface of a tank, comprising:
- a. a base having an openable cover forming a vehicle chamber therebetween, said base having a suction opening passing therethrough;
b. a plurality of obstacle contact sensing means movably secured to said base, said plurality of obstacle contact sensing means passing an electrical signal to said logic and control means when said sensing means is predeterminedly inclined to a vertical axis passing normal said bottom surface of said tank;
c. a plurality of independent drive means secured to said base;
d. liquid intake means being removable from said suction cleaning vehicle, said liquid intake means positionally located within said base cover forming a continuous particle path from said suction opening to an outlet in said base cover; and
, e. logic and control means for controlling translation of said cleaning vehicle in response to signals from said contact sensing means.

Abstract
An improved translatable suction cleaning vehicle which is adapted to moveably interface with a bottom surface of a pool and remove extraneous particulates therefrom. The improved cleaner incorporates suction inlet mechanisms, driving and sensing means for cooperation with logic and control mechanisms within a control box located external to and substantially displaced from the main body of the cleaner vehicle. An improvement to the cleaning vehicle provides for a plurality of mercury switches to act as the sensing means. When an obstacle is struck, the mercury switches are inclined and actuate the remotely positioned logic and control mechanisms. A further improvement to the vehicle provides for a driving mechanism which is manually controlled by an operator wherein the appropriate logic circuitry is removed from the logic and control mechanism.
