The present application discloses an underwater cleaning robot, which includes a chassis provided with a plurality of driving wheels. The chassis includes a primary suction port and a pump assembly. The primary suction port is provided with a channel which passes through the chassis. The chassis is connected to the filtering assembly. The filtering assembly includes a secondary pump port and a secondary suction port. The pump includes a primary pump port which is connected to the pump impeller. The secondary pump port is connected to the primary pump port. The secondary suction port is connected to the primary suction port. When assembling, the secondary suction port on the filtering assembly is in line with the primary suction port, and the secondary pump port is connected to the primary pump port. Finally, the filtering assembly is snapped into the chassis.

A pool cleaner for use in a pool may include a housing, a driving assembly, a traction assembly, and a filtration assembly. The driving assembly may include an inlet conduit configured to receive pressurized water, an impeller in fluid communication with the inlet conduit, an outlet conduit in fluid communication with the impeller, and an outlet nozzle coupled to the outlet conduit and may be configured to eject the pressurized water upward from the housing and into the pool in a parallel or oblique ejection direction relative to a vertical axis. The traction assembly may be coupled to the impeller to drive the housing across the pool and the filtration assembly may be configured to filter water from the pool.

A fluid distribution system for an underwater pool cleaner comprises an inlet body having an inlet for receiving a supply of pressurized fluid, a valve assembly body in fluid communication with the inlet of the inlet body and including a plurality of fluid outlets, a first one of the outlets provides fluid for propelling the underwater pool cleaner in a forward direction and a second one of the outlets provides fluid for propelling the underwater pool cleaner in a reverse direction, and a valve subassembly fluidicly driven by the supply of pressurized fluid and periodically switching the supply of pressurized fluid from the first one of the outlets to the second one of the outlets to periodically change direction of propulsion of the underwater pool cleaner.

Components of automatic pool cleaners (APCs) are detailed. The components may include brushes configured to attach to blades of scrubbers of the APCs. The flexible brushes may rotate as their associated blades rotate and have fingers which flex so as to adduce contact between a to-be-cleaned pool or spa surface and bristles protruding outward from sides of the fingers.

Some embodiments provide a pool cleaner having a housing including a bottom cover with a cover opening. A drive assembly is configured to drive one or more wheels. The pool cleaner further includes a supply mast, and a distributor manifold that receives water from the supply mast. A venturi vacuum assembly is in fluid communication with the distributor manifold, the venturi vacuum assembly designed to vacuum debris from a pool surface.

A pool cleaning robot as substantially illustrated in the specification. A method as substantially illustrated in the specification.

Autonomous, mobile cleaners for water-containing vessels such as swimming pools and spas are detailed. The cleaners are especially useful for cleaning spas, although they may function adequately in connection with certain other vessels as well. They may be designed and constructed in particular to avoid high centering so as not to become stuck when encountering obstacles within the spas or other vessels.

An electric pool-cleaning robot, including a housing, a first filtering mechanism and a rotating wheel. One end of the housing is provided with a first water inlet, and the other end of the housing is provided with a first water outlet. The first filtering mechanism is arranged in the housing. The water enters the housing through the first water inlet, and then flows toward the first filtering mechanism to be filtered. The filtered water flows out of the housing through the first water outlet. The rotating wheel is arranged on the housing, and is capable of rotating to drive the housing to move.
