Abstract: A fan shroud for a pump assembly having a pump, a motor and a drive. The fan shroud includes a fan shroud end cap coupled to a rear bell end of the motor, the fan shroud end cap having a vented surface for receiving cool air drawn by a motor fan during operation of the motor. The fan shroud further includes an extended shell sidewall extending from the fan shroud end cap across a length of the motor, and the fan shroud end cap and the extended shell sidewall are configured to surround the motor.

Abstract: Some embodiments of the invention provide a pool cleaner including a housing, a cavity defined within the housing, and a removable debris container received within the cavity. The pool cleaner includes a modular components that may be individually accessed and/or removed for servicing or replacement without disturbing other system components. The pool cleaner can include electronics modularly housed in an electronics housing. The pool cleaner can include a modular drive system for moving the pool cleaner, and a modular hydraulic system that draws water and debris into the housing, and discharges filtered water, providing thrust to the pool cleaner. Also, scrubbers individually coupled to the housing can include helical vanes configured to guide debris into a debris inlet of the pool cleaner.
