Extreme rainfall events are becoming the new normal. As climate risks escalate, more cities are experiencing rapid, unpredictable flooding that overwhelms traditional drainage systems. Underground garages, metro stations, tunnels, and industrial facilities are now among the most vulnerable zones—often requiring rapid, high-flow, and unmanned drainage solutions.
To meet this urgent need, Changsha Zondar Intelligent Technology Co., Ltd. has developed new generation of Hydraulic Multi-Function Drainage Robots (HMDR)—a family of intelligent, hydraulic-powered, all-terrain drainage systems engineered to perform in the harshest real-world flood scenarios.
Powered by high-output hydraulic systems, advanced mobility platforms, and long-distance intelligent control, the flood drainage robot lineup delivers unmatched efficiency, safety, and versatility. The series includes three specialized robots:
ZDPLC-1200 – Heavy-duty, high-flow self-propelled flagship
ZDPSC-800 – Compact amphibious drainage robot for restricted spaces
ZDPSC-300 – High-head obstacle-crossing specialist for long-distance and uphill pumping
Together, these machines form a complete, multi-scenario emergency drainage ecosystem for modern cities.

Unified Intelligent Monitoring Architecture Across the Zondar Drainage Robot System
All Zondar Intelligent drainage robots—including the 1200 self-propelled drainage robot, the 800 amphibious drainage robot, and the 300 high-head obstacle-crossing drainage robot—are built on a unified intelligent monitoring and control architecture. Regardless of size, mobility type, or application scenario, each robot operates under the same core monitoring logic, enabling consistent data acquisition, standardized alarm mechanisms, and uniform control behavior across the entire product lineup. This system-level design allows operators and emergency response teams to manage different drainage robots with a single operational mindset, significantly reducing training complexity and improving response efficiency during time-critical flood control missions.
Through this unified monitoring platform, real-time information on environmental conditions and pump operating status is continuously collected and processed, ensuring stable performance whether the robot is working in deep urban flooding, underground basements, narrow tunnels, or complex terrain with elevation changes. By applying identical safety thresholds, diagnostic rules, and protection strategies across all three models, ZONDAR ensures that operational risks are identified early and handled consistently, independent of the robot’s power class or deployment environment. This platform-based monitoring approach transforms individual drainage robots into a coordinated, intelligent drainage system, making Zondar solutions highly scalable, easier to deploy in mixed fleets, and ideally suited for modern cities seeking standardized, intelligent, and unmanned flood response capabilities.
