Automatic pool cleaner

Abstract

An automatic pool cleaner includes a housing, a filtering module, and an out-of-water detection module. The housing defines a water inlet and a water outlet; The filtering module is configured to filter fluid from the water inlet to provide filtered fluid. The out-of-water detection module comprises a floating unit and a sensing unit, which can make the floating unit move between the first and the second positions according to whether the pool cleaner is above the waterline. The sensing unit identifies the position of the floating unit and outputs a first signal or a second signal to the pool cleaner, thereby determining whether the pool cleaner is above the water surface.
