Dyson V12 Detect Slim+ vs V15 Detect: V12 saves 1.6 lb on repeated stair trips
The short answer
Buy the V12 when low weight matters on stairs, hard floors and short cleanups. Buy the V15 when deep carpet and heavier debris justify another 1.6 pounds at the wrist.

About this comparison
Choose between Dyson’s lighter everyday model and its stronger mixed-floor flagship.
The practical choice turns on peak suction and weight, then on the constraints in your own setup.
Before you choose
How they fit your plans
A furniture session makes the trigger difference more important
For repeated short passes across a sofa and stair edges, V12's on/off button avoids continuously holding V15's trigger. That can be a useful reason to choose the Slim even when both floor heads suit your home. Choose V15 if its trigger is comfortable and you value its larger debris capacity. Check each exact compact-tool bundle before expecting the same upholstery attachment from the two model names.
Facts behind this advice
This is about how the cleaner is operated during handheld work. It does not convert whole-stick weight into handheld weight, nor claim that button operation reduces fatigue for every user.
An upstairs fur cleanup has a disposal-location trade-off
With fluffy debris, V12's smaller bin may make a nearby trash can more useful than another few minutes of battery life. V15 offers more onboard capacity, but both still require manual emptying. Favor V12 for brief furniture touch-ups with disposal nearby. Favor V15 for a longer session in a room far from the trash if carrying the larger vacuum is comfortable.
Facts behind this advice
The inference concerns where interruption happens, not a promised number of rooms. Bin volume is useful for planning bulky debris, but fur packs unevenly and neither cleaner compacts or automatically removes it in a station.

Low weight matters more than maximum power

Meaningful differences
What changes the fit
| What changes | Dyson V12 Detect Slim+ | Dyson V15 Detect | Why it matters |
|---|---|---|---|
| Peak suction | 150 air watts | 240 air watts | The published output matters only when the room, surface or workload needs the extra headroom. It does not prove better results by itself. |
| Weight | About 5.2 pounds | About 6.8 pounds | This matters when the product must be lifted, moved, transported or stored after use. |
| Maximum runtime | Up to 60 minutes | Up to 60 minutes | Both records show the same result for “Maximum runtime”, so this row does not separate them. |
| Main floor tools | Fluffy Optic and Motorbar | Fluffy Optic and Digital Motorbar | Match the working hardware to the material and task. The component label alone does not prove a better result. |
What you give up
Every choice has a cost
If you choose Dyson V12 Detect Slim+
- Deep-carpet pickup trails heavier V15-class machines.
If you choose Dyson V15 Detect
- The small bagless bin still puts the user in contact with dust when emptied.
