Ryobi ONE+ 18V Cordless Chemical Sprayer
Ryobi's ONE+ 18V Chemical Sprayer earns a best-in-class spot for consumers who prioritize low cost and ecosystem convenience — it runs on the ubiquitous ONE+ battery platform so buyers with existing Ryobi tools save money on batteries and chargers. Technically it trades off tank size and continuous run-time for portability and price, making it a smarter budget choice than pro-grade options like the Milwaukee while handling lighter garden and spot-treatment jobs more comfortably than high-pressure handheld units like the Worx Hydroshot.

Milwaukee M18 Switch Tank 4-Gallon Backpack Sprayer
The Milwaukee M18 Switch Tank is the market leader for professional users thanks to its 4-gallon capacity, heavy-duty construction, and deep integration with Milwaukee's high-performance M18 battery platform that delivers longer run-times and higher pump power. Financially it sits at a premium versus consumer models but justifies that cost with commercial durability and faster job completion — outperforming lighter, cheaper units from Ryobi, Greenworks and Chapin when flow rate, longevity and serviceability matter most.

Worx WG584 40V Power Share Hydroshot
The Worx WG584 Hydroshot stands out as the most versatile, high-pressure portable unit in this list, using a 40V Power Share battery to deliver pressure-washer style performance from a compact, handheld form factor. It is financially attractive for homeowners who need multi-use cleaning and spot-spraying without the expense of a pro backpack sprayer — it won’t match the continuous chemical capacity or pump endurance of the Milwaukee Switch Tank or Chapin backpack models but offers unique quick-cleaning power the others don’t.

Greenworks 24V Backpack Sprayer
Greenworks' 24V Backpack Sprayer targets the mid-market consumer who wants a genuine backpack sprayer experience without the professional price, delivering a lightweight 24V battery system and decent run-time for garden and landscape maintenance. Technically it sits between Ryobi's compact sprayer and Milwaukee's commercial Switch Tank: more comfortable for longer jobs than handheld units and more affordable than pro-grade sprayers, though it concedes peak flow and ruggedness to the Milwaukee and some cost-savings to the Chapin value models.
