Abstract
Devices and methods for inhibiting movement of automatic pool cleaners (APCs) are described. Versions of the devices may cause pool water to bypass flowing through bodies of APCs. Alternatively, they may cause water flowing though bodies of APCs to bypass the associated motive force creators. The devices thus may constitute idler mechanisms, as they effectively prevent movement without requiring operation of the ultimate driver (i.e. the pump) to cease.
