How we reached each verdictThe numbers behind each model's score
Dyson V12 Detect Slim
Seven of 8 expert sources tested the V12 Detect Slim hands-on, and they broadly agree it is a light, maneuverable vacuum that excels on hard floors, with an expert score of 81. Owners are positive too (owner score 84 from 507 comments): 45% praise the light weight and 36% the suction, while 16% complain about the small bin. Reliability is the weak spot, scoring 58, with 17% of owner comments mentioning failures and 5% describing a unit that broke or died. Retail ratings are strong overall (87 from 33,118 votes, with 21,772 five-star ratings), but smaller retailer listings average only 3.79 stars across 126 ratings, and battery opinions are split almost evenly (12% negative vs 11% positive).
Shark Wandvac System
All 4 hands-on reviewers (published scores average an expert rating of 81) like the Wandvac's light weight and surprisingly strong suction, but all agree it's a quick-cleanup tool rather than a main vacuum. The recurring catches are battery life, measured at roughly 10 to 16 minutes, and a small bin. Among 80 owner comments, lightweight praise leads (15%), but battery complaints (10%) and units breaking or dying (10%) are just as common, and 31% of comments mention a failure, giving it a weak reliability score of 23. Confidence is low: expert coverage is only 4 reviews, owner theme counts are small, and Amazon buyers rate it a middling 3.8 stars from 666 votes.
