Dyson V12 Detect Slim Review

Dyson has launched a new vacuum series, the V12, and we’ll take a close look at it in this review.

Before testing this product, I thought it was another version of the V15 with a push-button switch, but there’s more variance.

It’s a smaller version than the Dyson V15 with a (slightly) smaller form factor.

This variant solves the most significant issues (of the V15) related to weight and bulkiness.

If you need something lighter than the V15 but with less power and deep-cleaning performance, the V12 will be an excellent compromise.

Introduction to the Dyson V12 Detect Slim

The V12 series is Dyson’s newest and addresses issues plaguing the full-sized V15, primarily related to its bulk and weight.

Before testing the V12, I thought that these models were similar. However, upon getting the V12 and comparing it closely to its older sibling, the V15 uses a (slightly) smaller form factor, making it lighter and more ergonomic.

You could see the size variance, how the V15 is much bulkier and more top-heavy than the V12.

Push Button Switch

Another upgrade is the push-button switch, which addresses another concern of consumers about constantly having to squeeze the trigger.

Squeezing a trigger makes a massive difference in comfort when using a full-sized cordless vacuum.

I’m not sure why Dyson waited this long.

The first Dyson with a push-button switch is the Omni-Glide, followed by the Micro 1.5KG. The V12 is the next option, along with the newer V15 variants.

Nonetheless, there are several downsides to the V12, the biggest being the smaller dustbin (0.35 liters vs. 0.77 liters).

The smaller battery’s next downside is that it won’t run as long as the V15, but it’s much better than the Micro 1.5KG (63 vs. 27 mins).

There’s no other way around it because the V12 uses a smaller battery to reduce its weight.

Floor Nozzles

Consumers will receive two nozzles out of the box: a standard brush roll (or the motorbar cleaner head) and the slim laser roller, featuring a green laser light that helps track almost invisible dust on hard floors.

Unfortunately, the standard brush roll differs from the V15 and lacks adjustable gates, which means it won’t pick up large debris like the V15.

It’s similar to the Dyson V8, featuring a brush design and seals behind it.

Again, you cannot interchange the Dyson V12 and V8 nozzles because the former has a smaller connecting port.

The same applies to the slim roller attachment, ensuring that the V12 attachments won’t fit in the V15, V11, or V10 variants.

Even with the plug variance, the tool dimensions are similar. Here’s a side-by-side photo of the slim laser roller of the V12 and V15.

These tools feature a green laser light that accentuates almost invisible dust more effectively than any white LED-equipped stick vacuum.

The photo above shows how dust pops against the green light. It’s one of the innovations Dyson introduced with the Dyson V15, which they’ve been rolling out with other models, such as the Outsize and V12.

Lighter Frame

Dyson’s V12 frame is slightly smaller than those of the full-sized models (V10, V11, and V15). It’s an in-between option between the V11 and Micro, a middle-ground alternative if the Micro’s dustbin is too tiny or needs something better on carpets.

Without any tools, the V12 Detect weighs a little over 3 pounds.

With the nozzle and extension tube, the weight increases to around 4 pounds and 9.6 ounces.

Add the push-button switch, which enhances usability and ergonomics, allowing consumers to hold the cordless vacuum without squeezing the cord.

The lighter frame helps, especially with specific tools like the under-bed attachment for cleaning underneath furniture.

Dustbin Design

Unfortunately, the smaller form factor negatively affects the V12’s dustbin capacity.

Whereas the full-sized V10, V11, and V15 utilize a generous 0.77-liter capacity, the V12’s is slashed by more than half at 0.35 liters.

It’s one of the compromises consumers will have to live with for better ergonomics.

Fortunately, the V12 retains the same sealed dustbin as its siblings, which didn’t leak during the fog test.

Two Batteries and Chargers

One of my favorite features of the V12 is it comes with two batteries and charges so that consumers can charge both simultaneously.

Please note that it’s a downsized battery (only 2500 mAh versus the V15’s 3600 mAh), but the runtime is still decent, with up to 63 minutes on the lowest setting (using the slim laser roller)—more than doubling the Dyson Micro’s runtime (27 mins).

Piezo Sensor

The Dyson V12 retains the Piezo sensor found in the V15, informing consumers of the debris size detected by a specialized sensor (the Piezo) that measures it based on the noise it generates.

The graph behind the vacuum motor visualizes debris flowing through the Piezo sensor. It automatically increases power when it detects more dirt (this is only applicable in the auto setting).

Watch this video to learn more about the Piezo sensor.

How Much Power Does The Dyson V12 Have?

Dyson cordless vacuums rank tops among cordless stick vacuums with airflow, and the V12 is no different. (at least in the max setting).

However, it lags behind the other full-sized options and is closer to the V8 than the V15.

Here’s the airflow output with the nozzle.

• Low: 24 CFM
• Auto: 28.52 CFM
• Max: 48.38 CFM

And the output using the wand.

• Low: 27.43 CFM
• Auto: 32.23 CFM
• Max: 58.74 CFM

It has a max output of over 58 CFM, (slightly) more than the V8 but much less than the V15.

Still, it’s an upgrade over the smaller Micro and will pick up more debris on carpets.

Cleaning Performance

Despite the lower airflow, the Dyson V12’s performance doesn’t differ much from the V15.

• Overall: 98.31%
• Hard floor: 99.8%
• Sand on hard floor: 99.9%
• Carpet: 99.45%
• Deep cleaning: 94.1%

Hard floor results

• Quaker oats: 99.2%
• Coffee grounds: 100%
• Quinoa: 100%
• Pet litter: 100%

The Dyson V12 works best on hard floors with the laser slim roller attachment, one of the best I’ve tested for hard-floor cleaning.

Dyson is the pioneer of the soft roller tool. The slim roller is another innovation, with the bright green LED accentuating almost invisible dust better than any LED-equipped stick vacuum.

Dust pops out inside a dark room, and you can easily track them.

Sand on hard floor

Another strength of the V12 is picking up sand; it got an average of 99.9% after two tests with fine-grade sand.

And it got this score with the first test at the lowest setting, which bodes well for usability because you can use it longer.

The eye test also reveals that it picked up (nearly) everything after one back-and-forth pass.

Edge cleaning

Another strength of the Dyson V12 Detect is its edge-cleaning performance, which I must say is excellent.

Check the before-and-after photos above.

It got everything out of this area with superb efficiency, gobbling up most of it after a few passes.

Hair wrap

• 5-inch strands: 96%
• 7-inch strands: 100%
• 9-inch strands: 92.5%
• 11-inch strands: 98%
• 13-inch strands: 100%

You’ll notice the results are a bit uneven, with some odd percentage swings. That’s partly because the slim roller tends to let hair wrap around its axle.

And depending on the entry point, hair strands can wrap in this area.

It’s the only reason why the V12 got 100% on the 13″ test and 92.5% in the 9″ inch experiment.

Aside from the hair wrapping on the axle issue, I didn’t see any hair accumulating on the roller, so it’s an excellent sign.

Always check the axle for buildup if you own pets or have long hair.

Carpet results

Next, we’ll look at how the Dyson V12 performs on carpet, and it picked up a high percentage.

Low pile

• Quaker oats: 97.8%
• Coffee grounds: 100%
• Quinoa: 100%
• Pet litter: 100%

Outside the Quaker Oats experiment, the V12 aced all the other tests, picking up a perfect 100%.

Despite the downgraded airflow, it has enough agitation to pick up surface debris on low-pile carpet.

Mid pile

• Quaker oats: 100%
• Coffee grounds: 100%
• Quinoa: 100%
• Pet litter: 100%

Surprisingly, the Dyson V12 achieved 100% in all four mid-pile cleaning experiments, which was a notable achievement given its lower airflow compared to the V15.

Again, this demonstrates that it has sufficient agitation to pick up surface debris, even on this type of surface.

Deep cleaning result

Unfortunately, the Dyson V12 Detect didn’t do as well at cleaning embedded sand as it did with surface debris.

It only got an average of 94.1% after two tests. There are a few reasons. The lowest airflow at the max setting is the most obvious, hampering its pick-up.

Another is the older brush roll, which uses the same bristles as the Dyson V8 Absolute.

Regardless, the result is still decent and among the upper echelon of cordless stick vacuums, but it lags behind the likes of the Lupe Pure, Dyson V11 Outsize, V15 Detect, and V11 Torque Drive.

Hair wrap on carpet

• 5-inch strands: 96%
• 7-inch strands: 100%
• 9-inch strands: 92.5%
• 11-inch strands: 30%

The Dyson V12 handled hair up to nine inches long with ease, but started to struggle with longer strands — picking up only about 30% of the eleven-inch hair.

Unlike the V15 with combs, the V12’s motobar attachment lacks an active anti-tangle system, limiting its effectiveness to a low quantity of nine-inch hair.

Tools Out of the Box

Here are the tools I got from the Dyson V12 Detect Slim Absolute Extra. One disclaimer, though: the tools you’ll get will vary depending on where you purchase, so always check with the merchant first before buying.

1. Dyson V12 unit
2. Motorbar cleaner head
3. Laser slim fluffy
4. Hair screw tool
5. Light pipe crevice tool
6. Mini soft dusting brush
7. Stiff bristled brush
8. Combination tool
9. Under bed attachment
10. Extra battery
11. Extension wand
12. Two battery chargers

One standout attachment is the Hair Screw Tool, which excels at picking up long strands of hair. I tested it with a heavy batch of hair over eleven inches long — and impressively, nothing wrapped around the brush.

Normally, I wouldn’t even think about using a standard mini turbo brush for this — everything ends up tangled around the roller, as it did with the V8.

But with the hair screw tool, there are no issues, and nothing is wrapped on the brush.

Another noteworthy tool is the light pipe crevice tool with an LED built in to illuminate its surroundings.

This tool is another innovation from Dyson and is very helpful for cleaning low-lighted areas.

How long will the Dyson V12 Detect run?

I conducted several experiments with the Dyson V12, measuring its run time by letting the motor run until it stopped from a full charge.

It ran up to 63 minutes with the slim roller attachment in the lowest setting and up to 37:50 minutes in the auto setting.

Laser slim roller results

• Eco: 63 minutes
• Auto: 37:50 mins
• Boost:

Standard nozzle results

• Eco: 63 mins
• Auto: 42:34 mins
• Boost: 6:25 mins

Multiply those figures by two, since this variant comes with two detachable batteries, so the total time increases to over 120 minutes.

How noisy is the Dyson V12 Detect?

Unfortunately, as with other high-airflow stick vacuums, the V12 Detect is noisy. I tested it using a sound meter, and the results are as follows.

• Low: 70.1 dB
• Auto: 72.5 dB
• Max: 80.7 dB

It ranged between 70 and 80 decibels; the latter is on the high side, so it’s not something you’d want to use late at night with the kids sleeping.

Does the Dyson V12 offer excellent value?

I’d say the attachments I got are a resounding yes. The under-appliance tool works great at cleaning areas under the bed, which are the toughest to reach inside my home.

Your answer will also depend on the tools you receive, so be sure to double-check with the store to confirm what’s included.

Nonetheless, I’d opt for the V12 Detect over the V15 Detect anytime because the former is cheaper, has better ergonomics, and performs nearly as well.

If your home has a lot of carpet, the V15 Detect is the smarter choice — its higher airflow helps it dig deeper and clean more effectively.

5 Reasons to purchase the Dyson V12 Detect

1. Better ergonomics: The V12 Detect’s lighter and more compact frame won’t be as tiring (to use) as the heavier V15.
2. No more trigger: Dyson replaced the trigger with a push-button switch, so no need to squeeze continually.
3. Excellent surface debris pick-up: While it has less airflow than the V15 or Outsize, it still picks up surface debris at a premium stick vacuum level.
4. Double the run time: Select V12 variants will come with two batteries and two chargers, so you can recharge them simultaneously!
5. Lots of tools: Consumers will get many attachments depending on their chosen variant.

The Verdict: Better Ergonomics Than the Dyson V15 Detect

The V12 Detect is Dyson’s response to the issues raised by their customers about the V15 Detect – its heavy frame, tiring trigger switch, and high cost.

It’s a middle-ground option between the Dyson Micro 1.5KG and the V15 Detect for those who want something that still performs without the bulk of a full-sized stick vacuum.

With all the extension wand and slim roller attached, the V12 is more than a pound lighter than the V15, which doesn’t sound much, but every ounce counts for these vacuum types.

It won’t have the feather-light steering of the Micro 1.5KG, but it cleans better on carpets and runs longer.
