Mayoki Cordless Submersible Sump Pump — DeWalt 20V/60V Compatible, 1320 GPH, Brushless, IPX8

The Mayoki cordless submersible sump pump is a tool-only, battery-powered pump compatible with DeWalt 20V/60V MAX batteries that delivers up to 1320 GPH for fast, portable water removal.

This compact, battery-operated pump is designed for quick water transfer tasks where corded power isn't convenient. Built around a brushless motor and a universal DeWalt battery interface (battery not included), it gives homeowners and professionals a mobile solution for draining basements, garden ponds, tubs, and jobsite dewatering without needing a generator or permanent power source.

How much water can it move and how high can it lift?

The Mayoki pump produces three selectable flow speeds to suit different jobs. At its top setting it reaches up to 1320 gallons per hour and can pump water vertically up to 26 feet, with lower settings conserving battery life while still delivering strong performance.

• High: up to 1320 GPH (approx. 22 GPM)
• Medium: about 1056 GPH for balanced runtime and output
• Low: around 792 GPH to extend battery life on lighter tasks

Will it protect itself and my battery if it runs dry?

Mayoki equipped the pump with an automatic shut-off that stops operation after it senses no water contact for 10 seconds. This reduces wear on the motor and conserves the connected DeWalt battery when the water level falls below the intake; note the pump does not automatically activate when water rises.

• Smart auto shut-off after 10 seconds without water
• Prevents dry-run damage and unnecessary battery drain
• Requires manual start; won’t auto-start when water level increases

What connections and portability features does it offer?

The unit is built for easy setup and transport. It uses a standard 3/4" garden-hose outlet for common fittings, includes an integrated strainer to block debris, and comes with a 15.4-foot power cord for positioning the pump and battery at a safe, dry distance.

• 3/4" garden hose connection for quick hose attachment
• Built-in strainer prevents clogging from larger particles
• 15.4 ft cord so battery can remain outside wet areas

Is it durable enough for regular outdoor and emergency use?

Designed with rugged construction and an IPX8 waterproof rating, this pump stands up to demanding environments and repeated use. The brushless motor increases longevity and reduces maintenance compared with brushed designs, making it suitable for seasonal cleanup, emergency basement pumping, and light contractor work.

• IPX8 waterproof rating for continuous submersion use
• Brushless motor for improved efficiency and durability
• Lightweight housing for carrying between sites and tasks

Who is this for: The Mayoki cordless submersible sump pump is ideal for homeowners who already own DeWalt 20V or 60V batteries and want a portable drainage solution, handymen and contractors needing a cordless dewatering option, and anyone seeking a compact emergency pump for basements, pools, ponds, or garden features. It’s sold as a tool-only unit, so buyers should plan to use their existing DeWalt battery or purchase one separately.
