RYOBI ONE+ 18V Cordless Fogger/Mister P2850 with 2.0Ah Battery & Charger — Adjustable Mist, Portable

The RYOBI ONE+ 18V Cordless Fogger/Mister P2850 is a portable, battery-powered sprayer designed to apply liquids evenly for pest control, sanitation, and landscape treatments without cords or hoses.

Compact and built on RYOBI's ONE+ 18V platform, the P2850 arrives as a ready-to-go kit including a 2.0 Ah battery and charger. Its cordless design gives you freedom of movement for treating lawns, greenhouses, patios, and indoor spaces where a fast, even mist is needed. The unit balances tank capacity with portability so you can cover moderate areas without frequent refills while avoiding the inconvenience of extension cords.

How does the RYOBI P2850 deliver consistent coverage?

The fogger/mister uses a motorized nozzle to produce a fine, uniform mist that disperses liquids evenly across surfaces and foliage. Adjustable output settings let you balance droplet size and flow rate to match the application, reducing waste and improving coverage.

• Fine mist atomization for uniform distribution
• Adjustable nozzle settings for droplet size control
• Steady battery-powered motor for consistent performance
• Tank design that supports even feed to the sprayer head

How long will the included 2.0 Ah battery run, and how quickly does it recharge?

Runtime depends on the output setting: lower flow uses less power and extends runtime, while higher settings shorten it. The kit includes a 2.0 Ah ONE+ battery and a charger that recharges the battery in a timeframe typical for compact RYOBI packs, offering quick turnaround for routine tasks.

• 2.0 Ah ONE+ battery for a balance of runtime and weight
• Charger included for convenient recharge between uses
• Variable runtime depending on nozzle setting and liquid viscosity
• Compatible with other RYOBI ONE+ 18V batteries for extended work

What liquids and applications are suitable for this fogger/mister?

The P2850 is made for low-viscosity liquids such as water-based solutions, disinfectants, insecticides labeled for fogging, and foliar nutrients. Always follow the chemical manufacturer’s label directions and safety guidance; do not use flammable or improperly formulated liquids.

• Water-based treatments, disinfectants, and labeled pest-control solutions
• Foliar feeding and greenhouse misting of approved nutrients
• Outdoor spot treatments around foundations and patios
• Not for use with flammable or non-recommended chemicals

How do I maintain and store the RYOBI fogger for reliable use?

Routine care keeps the sprayer working well: flush the tank and nozzle after each use, dry components before storage, and inspect seals and filters periodically. Store the unit and battery in a cool, dry place and follow RYOBI guidelines for battery care to preserve runtime and longevity.

• Rinse and flush tank and lines after every session
• Dry parts thoroughly before long-term storage
• Check nozzle and seals for clogs or wear regularly
• Store batteries per manufacturer recommendations
