Abstract
Bumpers and assemblies for swimming pool cleaners are disclosed. Such assemblies may include contoured frames to which flexible fins are attached to facilitate deflection of cleaners when obstacles are encountered. Side wings connecting the frame to the body of a cleaner may additionally be employed as part of the assemblies, as may a weight moveable about two axes. In use, the side wings both promote cleaner deflection and reduce body wear that otherwise would occur. The non-stationary weight permits continuous rebalancing of the cleaner depending on its location and orientation within a pool. An optional lower bumper facilitates operation of the cleaner by reducing the likelihood of its becoming trapped against objects such as steps located within swimming pools.
