Our Verdict

Dyson V15 Detect

Dyson V12 Detect Slim

The Dyson V15 Detect and the Dyson V12 Detect Slim each have advantages. The V15 is a better option for heavier-duty cleaning sessions, thanks to a more powerful motor that helps clear debris on carpeted floors more effectively. It also has a larger dustbin that won't need emptying as often. The V12 is notably lighter, making it easier to pick up and carry from room to room. While it isn't as effective as the V15 on carpeting, its lower output motor makes it less likely to get caught on dense carpeting. Unlike the V15, it can also automatically increase its suction when it encounters high concentrations of debris.
