Abstract: An underwater debris suction apparatus includes a power device and a filter device. The power device includes a suction component and a power drive device configured to provide power for the suction component. The underwater debris suction apparatus further includes a collection device, and the upper end of the collection device is provided with an opening. The suction component is at least partially located above the filter device or is entirely located in the space of the filter device. During operation of the suction component, unfiltered pool water enters the filter device through a water inlet channel and flows to the side wall of the filter device, so that the filtered water is discharged from the side wall of the filter device, and the debris that cannot be discharged from the side wall of the filter device falls into the collection device.

Abstract: A mechanism for detecting obstacles and mechanically reversing (a direction of) a pool cleaner includes a drive part in non-rotatable connection with a cleaner housing, an arresting assembly connected to the cleaner housing, and a rotary direction-changing assembly rotatably connected to the cleaner housing or the drive part. The arresting assembly cooperates with the rotary direction-changing assembly. The mechanism for detecting obstacles and mechanically reversing (a direction of) a pool cleaner is compact in structure, low in manufacturing cost, and can perform obstacle detection and change a direction of the pool cleaner. With the structure of the rotary direction-changing assembly capable of rotating relative to the cleaner housing, the cleaner, when meeting an obstacle, is allowed to change the traveling direction, thereby resulting in a high working efficiency.
