Is the Dyson V12 Detect Slim worth it?

It suits shoppers who want a light vacuum with strong hard-floor cleaning and automatic suction. If you have wall-to-wall carpet or a large home, a bigger-bin model may serve you better.

How does it compare with the V15 Detect?

The V12 is lighter and slimmer with a smaller bin and shorter run time. The V15 has more power and a larger bin but weighs more.

How long does the battery last?

Run time depends on the mode and floor type, and is shortest in Boost mode. Expect the longest run in Eco mode on hard floors.

Does it work on carpet?

Yes, with the Motorbar cleaner head, which is designed to resist hair tangles. The laser head is for hard floors.

When is the best time to buy?

Its price ranged from $520.55 on October 30, 2026 to $728.00 on November 4, 2026. Buying near the low end of that range saves the most.
