Milwaukee M18 HYDROPASS Brushless Stick Water Pump

The Milwaukee M18 HYDROPASS Brushless Stick Water Pump is engineered for fast, dependable water removal in demanding trade and site conditions. Designed to handle debris filled water without constant stoppages, this cordless pump is ideal for flooded garages, construction sites, inspection chambers, service pits, and emergency drainage where reliability matters most.

At the heart of the pump is Milwaukee’s advanced brushless motor technology, delivering strong, consistent performance while maximising efficiency and runtime from the M18 battery platform. The pump is capable of moving up to 5,670 litres of water per hour, making light work of large volumes of standing water that would otherwise slow down productivity on site.

What truly sets this pump apart is the HYDROPASS filter system. Unlike traditional pumps that clog easily when debris is present, the HYDROPASS design actively prevents inlet blockages, allowing continuous operation even in dirty or black water environments. This means less downtime, fewer interruptions, and greater confidence when working in unpredictable conditions.

The slim stick style design allows the pump to reach into deep puddles and confined spaces, with submersion capability up to 107 cm and a maximum head height of 5.1 metres. This makes it particularly effective for draining pits, trenches, and low lying areas where conventional pumps struggle to reach.

Built for professional durability, the pump features an IPX4 rated battery compartment to protect M18 batteries from splashing water, while the integrated run dry auto shut off safeguards the motor when water levels drop. The 1¼ inch outlet maximises water flow, and the supplied adapters allow easy connection to standard garden hoses for flexible water discharge options.

Compatible with all Milwaukee M18 batteries, this pump slots seamlessly into existing cordless tool kits, offering a portable, fuel free solution for rapid water transfer wherever it is needed.
