My 4 Sons M4 Battery Powered Backpack Sprayer – Key Features

Easy to Use: The large wide opening of the M4 allows for easy filling and adds a filter to eliminate dirt from water tank. On/Off and flow switches are available while the system is running and indicator lights let you know when it’s time to charge the battery.

Versatile – Works with Many Solutions/Chemicals: The M4 pump easily pumps a wide range of natural and synthetic fluids, such as acids, bleach, solvents, and chemicals. This ranges from lawn fertilizer and weed killers like Roundup to cleaning products like Wet and Forget, fence and deck stains, concrete sealants like LastiSeal, diesel, oil, de-icers, alcohol, mineral spirits, and much more.

Manual Pump vs Battery Operated:  The spray time is cut in half, compared to manual sprayers!  The M4’s large capacity sprays up to 200 gallons on a single charge. That’s equivalent to 50 tankfulls with a manual sprayer.

Battery Life:  A fully self-sufficient, automatic charger is included in the backpack of each model that reaches a full charge in eight hours or less. The charger can switch gradually from the fast-charging to full-charge mode to conserve battery life and does not require special residential or commercial outlets. It can be used year-round.

Built to Last:  To maintain the M4 in good working order, be sure to perform routine maintenance, including replacing the motor and battery every few years and thoroughly cleaning the machine.  In doing this, your sprayer will last for decades.

Safety Features:  The M4’s locking trigger prevents accidental spraying while heavy-duty shoulder straps are bolted to the sprayer to prevent accidental disconnection and/or dropping. The M4 is also much safer than manual sprayers if you need to climb ladders because it leaves one hand free to hold on.
