SOLO 414Li 10 Litre Battery Backpack Sprayer, Cordless with No Manual Pumping

SOLO 414Li 10 Litre Battery Backpack Sprayer: Cordless Spraying with No Pumping

The SOLO 414Li is a 10 litre battery-powered backpack sprayer for home and garden use, built around one big convenience: no manual pumping. An electric pump runs off a rechargeable lithium battery and holds a steady pressure the whole time, so instead of stopping to pump up a tank, you just switch it on and spray. For larger gardens, shrubs, plantations and weed control, that saves a lot of effort and gives more even coverage.

It runs on a 10.8V/2.5Ah lithium-ion battery that gives roughly 3.5 hours of continuous spraying per charge and recharges in about 2.5 hours, and both the battery and charger are included in the box. The pump holds a constant pressure of around 2.5 bar, delivering about 1.15 litres per minute, which works out to a large volume of spray on a single charge.

The 10 litre tank is UV-resistant with a large filling opening and a lid-mounted carrying handle, and the unit wears as a backpack with padded, adjustable shoulder straps. It comes with a 40cm unbreakable wand, an adjustable nozzle and an easy-grip shut-off valve, and the handpiece is a repairable Solo design with spare parts and accessories available, so it's built to keep going for years.

How to Use

• Charge the battery fully before first use

• Fill the tank through the large opening with your mixed solution, staying under the max mark

• Fit the battery, switch on, and spray; the pump keeps the pressure constant, so no pumping is needed

• Adjust the nozzle for a finer or coarser spray, and use the shut-off valve between passes

• Rinse the tank, wand and nozzle with clean water after each use

Getting the Best From It

• Recharge the battery after use rather than storing it flat, to help keep it healthy over time

• Rinse thoroughly after herbicides so residues don't carry over to the next job or clog the nozzle

• For broadacre lawn work, note this sprayer comes with a standard adjustable nozzle rather than a flat-fan; a compatible fan nozzle can give more even lawn coverage if that's your main use

• Store it out of direct sun with the tank empty and clean to protect the tank and seals

• Consider a spare battery if you regularly spray for longer than one charge allows
