Ryobi One+ R18TP-0 Cordless Submersible Dirty Water Pump (Bare Tool)

Contractors and homeowners tackling flooded basements, emptied ponds, or drained construction pits rely on the Ryobi One+ R18TP-0 to move dirty water fast—without dragging extension cords through wet areas. This 18V cordless submersible pump runs on any Ryobi ONE+ battery, delivering up to 4,500 L/h flow and a 7 m head, while its rugged housing and dry-run protection keep it working job after job.

Why choose it

The R18TP-0 eliminates the hassle and hazard of mains-powered pumps in wet environments. Its cordless design lets you place it anywhere, while the universal hose adapter and large particle tolerance mean fewer clogs and less downtime. Dry-run protection automatically shuts the pump off if water levels drop, extending motor life.

Ideal use cases

• Draining flooded basements, cellars, and crawl spaces
• Emptying ponds, water features, and swimming pool covers
• Removing water from construction trenches, pits, and excavations
• Transferring water from rain barrels or cisterns
• Emergency water removal during leaks or minor floods

Good to know

As a bare tool, the R18TP-0 requires a compatible Ryobi ONE+ 18V battery and charger (sold separately). For best performance, use a high-capacity battery (4.0 Ah or larger). Always rinse the pump with clean water after use in dirty or sandy water, and store it in a dry, frost-free location.
