The 20L Electric Backpack Sprayer with Stirring Function from Agronest Equipment addresses one of the most common frustrations in professional spraying: chemical solutions settling and separating inside the tank during use. The built-in stirring mechanism continuously agitates the tank contents, ensuring your herbicide, pesticide, or fertiliser mixture remains at a consistent concentration from the first spray to the last. This means even application rates across your entire spray area, with no hot spots from concentrated solution at the bottom or weak patches from diluted liquid at the top. Combined with the 12V rechargeable battery-powered electric diaphragm pump and a generous 20 litre capacity, this sprayer is a premium tool engineered for professionals who demand precision and consistency. The padded backpack straps and adjustable spray lance provide comfortable, controlled operation across hours of continuous use. If you work with wettable powders, suspension concentrates, or any product that tends to settle, this stirring sprayer transforms your application consistency.

Why Choose This Product
The stirring function is the defining advantage that separates this sprayer from every other electric knapsack on the market. Without agitation, wettable powders and suspension concentrates settle within minutes, leading to uneven application that wastes product and delivers inconsistent results. The Agronest Equipment stirring sprayer eliminates this problem entirely, ensuring uniform concentration throughout your spraying session. Combined with the electric pump that delivers rock-steady pressure, this is the most consistent sprayer in our range.

Frequently Asked Questions
The built-in agitator is a mechanical paddle inside the tank that continuously mixes the contents during spraying. This prevents wettable powders, suspension concentrates, and heavier-than-water chemicals from settling at the bottom, ensuring a uniform concentration is delivered through the nozzle at all times.
The agitator motor draws minimal additional power. You can expect approximately 4–5 hours of combined pump and agitator operation on a single full charge, only slightly less than the pump-only runtime.
Yes. The agitator can be switched off independently when using products that do not require mixing, such as pre-dissolved liquid herbicides or clear cleaning solutions.
Slightly. The stirring mechanism adds approximately 500g to the empty weight, bringing it to around 6.0 kg versus 5.5 kg for the standard 20L electric knapsack sprayer.
Wettable powders, suspension concentrates, flowable formulations, and any product that tends to settle or separate when left standing. Liquid fertilisers with micronutrient particles also benefit from continuous agitation.
Yes. Agronest Equipment stocks replacement agitator paddles, motor assemblies, and all wearing parts for the stirring sprayer model.
