Picture this: you’re faced with a flooded trench or a septic pit full of debris, and you need something more reliable than a manual pump. That’s where the Milwaukee M18 BLSWP-0 18V HYDROPASS Brushless Stick Water Pump from comes in - your compact, cordless solution that’ll ditch the heavy gear and repetitive cranking.

You simply dip it in up to 1.07 m deep, connect your standard hose via the handy Y-adapter, and let it go to work - clearing water at a serious rate of 5,670 L/hour (that’s nearly 95 L per minute) with a max lift height of 5.1 m.

What sets this apart is the unique HYDROPASS 360° filter system. Rather than clogging up on muck and grit like other stick pumps, it keeps the inlet clean so you can pump continuously - without frustrating blockages disrupting your work. And it’s not just efficient - it’s smart. The brushless motor delivers high performance and great battery life, while the IPX4-rated battery compartment gives your M18 packs protection from splashes and the elements.

This is comfortably light enough to carry around job sites, yet stable enough to stay planted when you drop it in the water. The 1.219 m aluminium submersible barrel means you don’t need to tiptoe into the mud; you can reach deep water without bending or straining.

On the connectivity side, the standard kit includes a 32 mm (1¼″) threaded outlet, a threaded adapter for 1¼″ BSPT male connections, and a Y-adapter for splitting into two ¾″ garden hoses - plus a tethered cap so nothing slips away when you switch hoses

What does this mean on the ground? You spend less time hauling big pumps, more time on actual draining. You’re less likely to get blocked mid-job. You operate confidently in tight spaces or flooded areas without fuss. And because everything's cordless and compatible with gear you're already using, setup and swap-outs are quick.

At the heart of this tool is the brushless motor that allows you to use it efficiently.  As part of the design, the tool utilizes every bit of battery power when you need, all while reducing the need for ongoing maintenance by reducing the amount of heat generated and working more efficiently.

The technology in creating a brushless motor system allows for perfect symmetry between battery power and usage ensuring you get all the power you need, when you need it.
