Market Context

Compared to the same brand’s similar models: The Ryobi 18 Volt One+ 6 Gal. The Cordless Wet/Dry Vacuum has a much larger 27.2L dirt compartment compared to the 13.2L dustbin of the Ryobi 18 Volt One+ 6 Gal. Cordless Wet/Dry vacuum (this review)

Compared to other brand’s similar models: The Black+Decker dustbuster AdvancedClean+ Pet is much smaller than the Ryobi 18V One+ 3 Gal. Project Wet/Dry. While the dustbuster is designed for spot cleaning in homes and comes with a turbo brush, the One+ is meant for cleaning workshops and doesn’t come with a turbo brush.

While the Ryobi 18V One+ 3 Gal. Project Wet/Dry supports cleaning wet messes, the Hoover ONEPWR Cordless Hand Vacuum is designed for dry debris only. Weighing just 3.42 lbs, the Hoover vacuum is easier to carry around than the 10.36-lb One+.

Critic Consensus

Top experts hailed the Ryobi 18V One+ 3 Gal. Project Wet/Dry Vacuum, recommending it for workshops. Researchers at Pro Tool Reviews hailed its spacious 13.2L dustbin. However, if you prefer a large dirtbag-equipped compartment, explore the Roborock H7 review. Testers hailed this Ryobi vacuum’s wet cleaning ability, although emptying the bin can be messy.

Browse our Shark ION W1 WANDVAC review for a hygienic one-touch emptying system. The Ryobi vacuum produced an impressive 10.43 kPa of suction and removed a whopping 100% of the large debris on bare floors and 90% on high-pile carpets during testing. It removed an impressive 100% of the pet hair on all floor types.

Pet owners who require a turbo brush can consider the Samsung Bespoke Jet review. Editors at Tool Review Zone criticized its heavy 10.36-lb mass, however. For a portable alternative, check out the Miele Triflex HX1 review. The One+ has a low 15-minute runtime and a high 88.7 dBA noise rating. Consider the Samsung POWERbot R7040 review for a better runtime.
