The V15 and V12 sit at different points in Dyson’s cordless range, with the V15 positioned as the more feature-rich flagship and the V12 as a lighter, more accessible option.
Quick Answer
The V15 offers stronger suction, longer real-world runtime and laser dust detection, making it the better choice for larger homes, thick carpet or allergy-affected households. The V12 is lighter and more affordable, suiting smaller homes and apartments where its slightly lower runtime and suction are less of a limitation.
Suction and Performance
The V15 is generally positioned with stronger sustained suction, particularly noticeable on thick carpet, while the V12 delivers solid performance suited to lighter, more general cleaning needs.
Runtime and Battery
The V15 typically offers longer real-world runtime on medium power, which matters more for larger homes needing to cover more floor area in one charge. The V12’s shorter runtime is less of a limitation in smaller apartments.
Weight and Handling
The V12 is generally the lighter of the two, which can matter for users with limited strength or homes with lots of stairs, while the V15’s added features come with a small weight trade-off.
Special Features
The V15 is known for laser dust detection, which illuminates fine dust invisible to the naked eye, and a particle-counting display — features the V12 doesn’t include.
