Solo Battery Powered Backpack Sprayer – Professional Lawn & Garden Range

The Solo battery powered backpack sprayer range delivers constant pressure, cordless convenience and professional performance for The Lawn IQ users who want consistent spray quality without any pumping. Designed in Germany and built for long life, each sprayer applies The Lawn IQ fertilisers, wetting agents, herbicides, fungicides and biostimulants with accuracy and uniform coverage. These sprayers feature UV-stabilised tanks, lithium-ion power systems, Viton chemical resistant seals, stainless steel lances and quiet low-vibration motors that make them suitable for both homeowners and professional contractors.

The range includes four models. Each offers the same level of quality and core technology, while giving you different levels of capacity, battery power and pressure control so you can choose the unit that best suits your lawn size and workload.

The 18 L 417 Li is the high-capacity option designed for large areas and extended use. It is ideal for acreage, sports turf and bigger residential properties. The 417 Li has long runtime, a strong pump, a reinforced harness system and excellent balance. This model is built for users who want to spray for longer periods without stopping and who need reliable output across wide turf areas.

The 16 L 442 Li is the professional model for daily operators. It has a more advanced electronic pressure control system that keeps pressure stable from the first litre to the last. It also has thicker tank walls, upgraded fittings and a premium harness for comfort during long sessions. If you spray often or need the most consistent droplet size and pressure stability, the 442 Li is the premium choice and is designed for long service life under regular use.

The 10 L 417 Li S is the compact two-speed option for landscapers and advanced home users. You can switch between low pressure for delicate work and high pressure for broad coverage or extended reach. It is lighter, very comfortable to wear and flexible enough to handle both tight spaces and open lawn applications while still using the same long-life lithium power system.

The 10 L 414 Li is the home and garden model for users who want a simple, lightweight and easy to operate sprayer. It offers constant pressure, a quiet motor and a compact tank that suits The Lawn IQ maintenance on small to medium lawns. It carries the same build quality as the larger models at a size and price that is perfect for homeowners.

All models share the same key advantages. They remove the need for pumping and provide constant pressure for consistent results. They use lithium-ion batteries with reliable runtimes that match their tank sizes. They include Viton seals for long-term chemical resistance, stainless-steel lances for durability, comfortable harness systems and UV-stabilised tanks suitable for Australian conditions. They are quiet, low vibration and built for accurate, efficient spraying of all Lawn IQ liquid products.

Typical coverage per tank depends on the model and nozzle settings. The 10 L units generally cover 200 to 600 square metres per fill. The 16 to 18 L units typically cover 400 to 1,000 square metres per fill. Battery and charger are included with all variants along with a multi-nozzle set and stainless steel lance.
