An automatic pool cleaner comprising a housing and a base. The housing comprises a suction flow pathway, an impeller disposed within the housing and in fluid communication with the suction flow pathway such that water traveling through the suction flow pathway spins the impeller, an off-center cam that extends through the impeller and is configured to rotate as the impeller rotates, and two spring biased valves. Each valve comprises a valve seat, and a spring biased poppet configured to seal against the valve seat, the poppet having a rod with a spring disposed around the rod. The base comprises two feet, each foot having a spring-biased pad extending from each end of the foot, two A-arm assemblies, one for each foot, and a suction port that extends through the base.

Various aspects of the present disclosure are directed to swimming pool vacuum cleaners. In one example embodiment, the pool vacuum cleaner includes a main body having a housing with an impeller driven by an electric motor, an inlet opening in a bottom region of the housing, and an outlet opening on an outlet side of the housing. The vacuum cleaner further includes a collecting container receptacle that accommodates a collecting container arranged in the region of the outlet opening, a rod receptacle releasably connected to a guide rod arranged in the region of the outlet side, and a guide fork pivotably connected to the housing about a pivot axis. The rod receptacle arranged on the guide fork. The pivot axis is arranged at a distance from a center of mass of the main body, and the center of mass is arranged between the pivot axis and the outlet opening.

A broom vacuum cleaner for cleaning swimming pools including a main body, pumping means, a suction head and an upstream filter, placed inside the main body and upstream of the pumping means, the suction brush includes a downstream filter placed outside the main body and downstream of the pumping means, and the upstream and downstream filters are coaxial.

A pool cleaner including a housing, a driving assembly, a brush assembly, and a removable debris container. The removable debris container is coupled to the housing through a locking member in the brush assembly.

A reconfigurable vacuum attachment may include a bell-shaped housing. The bell-shaped housing may have a bell-opening and a hose-interface. The hose-interface may be configured to hydraulically couple with a vacuum hose. A skimmer-plate may be attachable to the bell-opening and include a skimmer-aperture extending through the skimmer-plate. The reconfigurable vacuum attachment may further include a removable brush assembly. The brush assembly may host a rotatable brush coupled to a brush driver. The brush driver may be configured to hydraulically couple with the vacuum hose and convert water flow into a torque and spin the bristles. A buoy may be attached to the housing allowing the reconfigurable vacuum attachment to be used as a pool skimmer. The reconfigurable vacuum attachment is useful for skimming a pool surface and dislodging and vacuuming matter from a pool wall.

A suction head for submersible use in the water of an artificial pool. The suction head having a body provided with a suction duct and a suction pump placed inside the suction duct. The suction pump includes an electric motor coupled to a propeller. The rotation of the propeller producing suction along the suction duct between a suction mouth and an upper opening of the duct. The suction head further includes a central deflector placed between the motor and the propeller so as to prevent bulky debris from piling up below the propeller and discharging it to the periphery of the suction duct.

A swimming pool cleaner may operate within a pool during a cleaning cycle. The duration of the cleaning cycle may be tailored, or optimized, for the pool by determining a maximum length of time between, for example, a rotation of the cleaner and when it next detects a wall of the pool during a designated interval. As another example, deducing information relating to rotation speed of the cleaner also may be useful in determining the tailored cleaning cycle.

Automatic swimming pool cleaners may include cable storage systems for storing an electrical cable on, in, or near a body of the automatic swimming pool cleaner. Some cable storage systems may include a cable storage device on the body of the automatic swimming pool cleaner and/or on a cover for the body of the automatic swimming pool cleaner. Cable storage systems may additionally or alternatively include a cable storage device on the electrical cable. The automatic swimming pool cleaners may be configured and balanced to be supported by their rear portions essentially upright when stored.

A submersible vacuum cleaner to clean artificial pools, such as swimming pools. A suction head connected to a suction duct leading into a filter bag. A motor coupled to an impeller located within the suction duct. The spinning of the impeller producing a suction. A battery powering the motor. The motor and the battery being placed in a watertight compartment, itself mostly placed within the filter bag, so as to obtain a compact design of the vacuum cleaner.

An omni-directional wheel for a pool vacuum head includes a first frame and a second substantially identical frame, each frame having a hub rotating around a common axis, lower supports extending radially from the hub, risers extending from the hub along the common axis, and upper supports individually coupled to the risers, the upper supports extending radially from the common axis. Rollers coupled to the first frame and the second frame, are radially spaced from the common axis on each frame. The rollers rotate normal to the common axis to impart omni-directional movement. When the first frame and the second frame are interlocked, the risers on the first frame engage the hub on the second frame, and the lower supports on the first frame engaging the upper supports on the second frame, maintaining the rollers in a staggered arrangement around the wheel.
