Dyson V15 Detect vs Dyson V12 Detect Slim
Quick take: The Dyson V12 Detect Slim costs $380 less.
Which one to buy
Most V12 Detect Slim owners started by picking up a V15 Detect and putting it back down. That is the decision in one line: the V15 is the stronger cleaner, the V12 is the one that is easier to live with, and the V12 costs $380 less. Both keep the green dust laser, the particle counter that boosts power on dirty patches, whole-machine HEPA sealing, a removable battery and a 2-year warranty.
The V15's advantages are carpet and capacity. It is rated at 240 AW against the V12's 150, its owners rank its deep carpet cleaning near the top of long-term tests, and its 0.77 L bin holds more than twice the V12's 0.35 L. V12 owners admit thick carpet takes extra passes and that pet households empty the bin once or twice per clean.
The V12's advantages are weight and the switch. At 5.2 lbs to the V15's 6.8, owners call it the Dyson they reach for daily and prefer it for stairs and cars. It has a power button, while the V15's hold-down trigger is that machine's single most repeated complaint, with owners describing index-finger fatigue on long cleans. V15 owners also report a minority pattern of trigger failures, charging faults and repeated warranty swaps. Some V12 owners report battery fade around year two.
The laser works the same on both, so on hard floors the results look identical.
Dyson V15 Detect
Suits you if your home has a lot of carpet or shedding pets and you want the stronger suction and bigger bin, and can tolerate holding a trigger.
Dyson V12 Detect Slim
Made for apartments and mostly hard floors, or if weight and the V15's trigger would wear on you; it costs $380 less.

Dyson V15 Detect vs Dyson V12 Detect Slim: common questions
Is the V15 Detect worth $380 more than the V12 Detect Slim?▾
If you have thick carpet or pets, yes: it is rated at 240 AW against 150 AW and its bin holds more than twice as much. On hard floors owners say the laser heads clean the same, so smaller hard-floor homes get little for the extra money.
How bad is the V15's trigger compared with the V12's button?▾
It is the V15's most repeated owner complaint. Quick daily passes are fine, but 30-plus-minute cleans fatigue the index finger. V12 owners who came from a V15 name the power button and the lighter weight as the two reasons they switched.
Which handles pet hair better?▾
The V15 Detect, mainly because of capacity and suction. Its owners say the de-tangling comb and screw tool largely stopped hair wrap. V12 owners with pets have to empty the 0.35 L bin once or twice per whole-home clean, which gets old in a shedding household.
