Is the Dyson V12 Detect Slim worth it?
Yes — for flats and smaller homes.
Great choice- Light and easy to carry
- Laser and dust sensor like the V15
- Good on hard floors
- Small bin — fills fast in bigger homes
Get it if…
- You live in a flat or a smaller home.
- Weight matters — stairs, wrists or shoulders.
- You have mostly hard floors.
Skip it if…
- You have lots of thick carpet.
- You have pets that shed a lot.
Get this instead if…
Why this verdict?
It keeps the V15's laser and dust sensor in a noticeably lighter body, so stairs and high-up cleaning are easier. The bin is small and there's less power for thick carpet, so it suits flats and smaller homes.
Known problems owners report
- The bin needs emptying often.
- Runtime is shorter than the V15 on full power.
