EvaClean Protexus Cordless Electrostatic Backpack Sprayer — 23,000 sq ft Tank, 16.8V Battery

The EvaClean Protexus Cordless Battery Powered Electrostatic Backpack Sprayer is a rechargeable, ergonomic electrostatic sprayer that delivers charged droplets for fast, even coverage of large commercial spaces.

Designed for facility teams, janitorial crews, and cleaning contractors, this cordless backpack sprayer uses electrostatic charging to wrap disinfectant droplets around surfaces, including undersides and hard-to-reach areas. The unit combines a high-capacity tank and a long-running lithium-ion battery with a precision nozzle and an ergonomic harness so operators can treat rooms quickly without tethering to an outlet.

How fast can it treat rooms and large facilities?

The Protexus is built for rapid coverage of sizable spaces: one full tank can treat many rooms, and spraying a standard-sized room typically takes under three minutes. Its cordless construction eliminates the need to hunt for power outlets, letting teams move continuously through large facilities.

• Covers up to 23,000 sq ft per tank under typical application conditions
• Disinfects individual rooms in about three minutes
• No cords or refill stops for uninterrupted operation

What makes the electrostatic system more effective for surface coverage?

Electrostatic technology imparts an electrical charge to droplets so they are attracted to surfaces and wrap around objects for three-dimensional coverage. That means treated liquid reaches vertical, horizontal, and hidden surfaces more consistently than manual wiping or conventional spraying.

• Charged droplets adhere to all sides of objects, including undersides
• 360-degree wrap-around coverage reduces missed spots
• Useful for furniture, equipment, and complex target surfaces

How long does the battery last and how is the user experience designed?

The integrated 16.8V lithium-ion battery provides all-day runtime for most facility workflows, with LED indicators to track charge level. The backpack harness and lightweight construction spread weight evenly to reduce fatigue during multi-hour shifts, and a trigger lock plus a built-in headlight add safety and precision.

• IPX4-rated battery with a 4-hour runtime per charge
• LED battery indicators and trigger lock for safe transport
• Adjustable shoulder straps and padded back panel for comfort

Which solutions can I use in the Protexus and how precise is the spray?

The sprayer is optimized for EvaClean PurTabs (sold separately) but accepts a wide range of disinfectants and sanitizers used in commercial settings. A 60-micron nozzle produces fine, uniform droplets to limit waste and overspray, while the precision nozzle and light help when treating tight or poorly lit areas.

• Compatible with EvaClean PurTabs bleach-free cleaner and many disinfectants
• 60-micron nozzle for consistent droplet size and reduced chemical usage
• Precision headlight for accurate targeting of confined spaces

Who is this for? The EvaClean Protexus Cordless Electrostatic Backpack Sprayer is aimed at facility managers, cleaning contractors, school and hospital maintenance teams, and hospitality operations that need fast, repeatable surface treatment across high-traffic environments. It suits crews that value cordless mobility, ergonomic wear, and electrostatic wrap-around coverage for efficient daily or periodic treatment cycles. A one-year limited warranty covers defects in materials and workmanship from the purchase date.
