ALIENTABI 4-Gallon Battery Backpack Sprayer — Self-Cleaning, Variable Pressure up to 116 PSI

The ALIENTABI 4‑gallon battery backpack sprayer is a self‑cleaning, high‑pressure sprayer built for precise weeding, cleaning, and large‑area spraying with up to 116 PSI and over four hours of continuous run time.

This professionally engineered sprayer pairs a 4‑gallon tank with a powerful battery and variable pressure control so you can switch between fine mist and a long‑reach stream without manual pumping. Its standout feature is an automatic self‑cleaning cycle that flushes the hose and pump at the touch of a button, reducing chemical buildup and shortening maintenance time. Rugged construction, a long spray distance, and user‑friendly controls make it suitable for gardeners, landscapers, and property managers who need efficient, reliable coverage.

How does the variable pressure system improve spraying results?

The ALIENTABI sprayer offers a continuous pressure range from 8 to 116 PSI, letting you dial in the exact output for the task. Lower pressures produce gentle misting for foliar applications while higher pressures create a concentrated stream for distant targets or heavy cleaning jobs.

• Precision knob adjusts pressure smoothly—no preset gear jumps.
• Switch between mist and stream quickly for versatile use.
• High pressure supports a spray range beyond 33 feet for wide coverage.

What makes the self‑cleaning feature useful and how does it work?

ALIENTABI’s patented one‑key self‑cleaning flushes the pump and hose internally, preventing residue buildup that shortens component life. It also makes changing liquids safer and faster by rinsing out remnants without disassembly.

• Automatic cycle cleans internal plumbing with a single button press.
• Minimizes corrosion and chemical waste for longer equipment life.
• Enables quick switching between different solutions or rinsing after use.

How long can I spray on one charge and how big an area will it cover?

This battery model runs continuously for over four hours and can deliver more than 58 gallons per charge, making it vastly more efficient than manual pumps. The long battery runtime and powerful nozzle let you treat larger lawns, orchards, or commercial properties without frequent recharging or refills.

• Continuous operation exceeding 4 hours per full charge.
• Sprays 58+ gallons per charge—useful for mid to large jobs.
• Effective reach beyond 33 feet for spot treatment or tall targets.

Built for frequent use, the unit combines sturdy plastic housing with corrosion‑resistant internal parts and a tested assembly process that includes leak checks. The self‑cleaning cycle and simple controls reduce maintenance time, while clear customer support guidance helps resolve issues quickly.

• Factory quality checks include water leakage testing before shipping.

• One‑key cleaning and accessible components simplify upkeep.

Who is this for?
