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.
