The hull is constructed with waterproof stainless steel and HDPE material, and has an IP68 waterproof rating, allowing it to operate safely at a water depth of up to 20 meters. It is powered by a 24V 100Ah rechargeable lithium battery, supporting up to 8 hours of continuous operation on a single charge to support long‑term silt removal tasks. The device is equipped with a 4K underwater camera that transmits real‑time operation footage, helping operators make accurate adjustments to working positions. It uses a compact cutter‑suction dredging system that helps clean underwater silt and fine sediment, and is suitable for operations in confined spaces.

Detailed technical parameters include maximum operating water depth of 20 meters, maximum dredging depth of 8 meters, total weight of 120 kilograms, hull made of stainless steel + HDPE, slurry discharge pipe diameter of 50 millimeters, powered by 24V 100Ah rechargeable lithium battery, controlled by 4G remote control, protection grade of IP68, dredging capacity of 5 cubic meters per hour, underwater camera resolution of 4K ultra-high definition, single charge operating time of 8 hours, overall equipment size of 600*400*300 millimeters. It is equipped with a special storage box and charging equipment for easy carrying and storage, and a real-time operation data display system to view parameters such as dredging volume and remaining battery power.

It is mainly applicable to municipal drainage pipeline dredging, shallow water area silt removal of small reservoirs, landscape pool maintenance, narrow river section dredging, underwater pipeline inspection and dredging and other scenarios. It is suitable for municipal operation and maintenance departments, community properties, small dredging teams, which can quickly complete silt removal operations in narrow space water areas, solving the dredging demand that traditional large-scale dredgers cannot enter.
