Summary

The Dyson V15 Detect is a cordless vacuum with a 60 minute run, 230 air watts of suction power, and 3 suction levels. It has an advanced digital display on the back of the motor showing run time, maintenance alerts, and clean reports. The cleaning reports are based off of an internal particulate sensor, which shows how many and what size particulates are being vacuumed. The V15 brings back the Fluffy soft roller cleaning head, in addition to an upgraded version of the High Torque head. After the V11 and Outsize I wondered how Dyson could make an improvement to their design, but they truly did take it to the next level (yet again). An incredible machine that’s easy to use, provides the most suction of any cordless vacuum in the world, and a sizable 1 hour run time.

🧪 Performance

Right out of the gate, let’s hit performance since this is arguably the most important parts of any vacuum cleaner.

Dyson V15 Detect
Dyson V15 Detect

To test the cleaning performance of the Dyson V15 Detect, we put it through the same testing that all of our Dysons (and all other brands) go through.

We test on three different floor types, including hardwood floors, low pile carpet, and high pile carpet.

Overall cleaning performance on the V15 was excellent. The V15 was able to remove 99.4% of the total debris by weight that we tested against.

Hardwood Floor Cleaning

On hardwood floors we tested using the new slim fluffy cleaning head. The V15 removed 100% of all 4 debris types. It had zero issues with any debris and easily cleaned up to the edges. The front laser light is also a nice addition, helping to improve visibility for finer debris types.

The biggest advantage the V15 Detect has on hardwood floors is the soft roller cleaning head. We didn’t see a Fluffy cleaning head on any US-based Dyson 2019 or 2020 models, so its exciting to see it making a return.

Low Carpet Cleaning

On low pile carpet the V15 removed 99.3% of total debris. The only slight misses were on kitty litter and sugar, where it removed 99% and 98%, respectively.

Kitty Litter

Sugar

With our particular carpet the V15 had trouble engaging the highest suction levels.

We weren’t able to keep the front seal gates fully lowered or use boost mode, as the brushroll would create too much down force and stop spinning.

It’s possible this is an issue with our specific carpet type, but in any case, the inability to use max suction and max seal likely resulted in the 99% and 98% removal rates on sugar and kitty litter.

High Carpet Cleaning

On high pile carpets the V15 removed 98.8% of total debris. Just as with low pile carpet, the misses were kitty litter and sugar, which were removed at a rate of 99% and 96%, respectively.

Cereal

On high pile carpets we were able to use the lowest gate setting and boost suction. So it felt like we had more than sufficient suction power.

While the 99% on kitty litter isn’t much of a concern, the 96% on sugar really did surprise us. The previous Dyson V11 and Dyson Outsize both seemed to handle sugar on high pile carpets better.

Run Time Tests

According to Dyson, the battery on the Dyson V15 can run for up to 60 minutes, depending on the type of cleaning that you’re doing.

We put the V15 through a series of real world run time tests to see how long it can run on the various modes. Here’s what we found:

  • Eco Mode = 68 minutes, 30 seconds
  • Auto / Medium Mode = 45 minutes, 30 seconds
  • Boost Most = 8 minutes, 55 seconds

The 3 tests above were run with the High Torque cleaner head. For these tests we continuously held the trigger from 100% power until the battery died.

Hair Removal Tests

The Dyson V15 includes an anti-tangle system on the High Torque cleaner head, as well as an anti-tangle brushroll on the new Hair Screw tool (mini motorized head).

We put both to the test vs. hair to see how they would do at removing hair from sofas, hardwood, and carpet…and to see if they would tangle or not.

The Hair Screw tool had zero issue removing hair from the sofa. It easily removed all hair and zero hair strands tangled around the brushroll.

The High Torque cleaner head too had zero issue at removing the hair from the hardwood and carpet. While the vast majority of hair did not tangle around the brushroll, a few strands did.

Even so, this is easily the best anti-tangle brushroll system we’ve tested to date.

🧬 Design

The look of the Dyson V15 Detect isn’t entirely different from the rest of the V Series, concerning aesthetics alone. But on the inside there are quite a few notable differences that really make it stand out.

How Does the V15 Clean?

The Dyson V15 Detect takes a new approach to standard vacuuming, which has a more science-backed design. Instead of simply cleaning small debris, the V15 Detect aims to show you just how well it is cleaning up these ultra-small particulates.

New features on the Dyson V15 include:

  • Floor level laser: helps to expose dust particles at the floor level so you can better clean them up (integrated into the Fluffy head only)
  • Piezo sensor: counts and measures the size of dust particulate
  • Ultra advanced digital display: data from the sensors is shown on the digital display so you know exactly what is being cleaned
  • Adjustable suction: automatically adjusts motor suction, based and cleaning head setting on floor type and particle size

The Digital Display

Dyson V15 display screen
Dyson V15 display screen

The V15 Detect is designed to detect and react.

It detects particles on the floor and adjusts the suction power to react to changing cleaning needs.

The digital display shows three main pieces of information:

  • Cleaning Mode (Eco, Auto, or Boost)
  • Estimated Remaining Run Time
  • Particle Levels Captured

The information on particle levels is broken down into four colored bars. Each colored bar counts particles of different size ranges that have been detected and categorized by a Piezo Sensor.

Dyson V15 display
Dyson V15 display

How does it work?

When the bar stops increasing, that means that the particle has been fully cleaned from the floor / surface.

Do you need to be in a particular mode?

The particle count works with all modes on the machine. The sensor is located in the main body of the machine so it’s an on-board feature, regardless of which cleaning head or tool you’re using.

Size & Dimensions

Tools & Accessories

The Dyson V15 comes with a pretty large selection of tools and accessories, many being standard to the V-Series lineup, but also introducing three brand new tools.

Dyson V15 tools, accessories, & attachments

Here is a complete list of the tools included:

  • Laser Slim Fluffy Cleaner Head ⭐ NEW
  • Upgraded High Torque Cleaner Head ⭐ UPDATED
  • Hair Screw Tool ⭐ NEW
  • Crevice Tool
  • Stubborn Brush
  • Wand Clip
  • Combination Tool
  • Docking Station
  • Charger

⭐ Laser Slim Fluffy Cleaning Head (NEW)

The Laser Slim Fluffy cleaning head is included with the V15 Detect and Dyson Outsize Absolute+. It has a 10″ wide cleaning path and is best suited for cleaning hard floors.

This head is made of nylon and anti-static carbon fiber filaments.

Three of the biggest advantages of this cleaning head are:

  1. Lower profile
  2. Include a front laser light
  3. Washable

Low Profile: The lower profile makes it easier for this Fluffy head to squeeze under furniture or hard-to-reach spaces and it is also quite a bit slimmer than the first-Gen Fluffy cleaning head.

The Laser: The laser light is also unbelievably cool. It allows a lens to spread a visible green light into a fan shape exactly 1.5° down and 7.3mm from the ground, to illuminate fine dust so it is visible and therefore easier to clean.

This light is only integrated on the Fluffy head (not included on the High Torque head). If possible, it’s best to close the shades / blinds and turn down the lights. The lower the light, the more the laser will be visible.

Washable: Lastly, this cleaning head is washable, making it easy to keep it clean and operating at peak performance.

⭐ High Torque Cleaner Head (UPDATED)

The High Torque Cleaner head is similar to the Torque Drive head on previous V Series Dysons, but has been upgraded a bit, making this head unique to the V15 Detect currently.

Dyson V15 High Torque head

It integrates an anti-tangle technology and can automatically adapt suction and power.

This head is designed to monitor brush bar resistance 360 times per second so that it’s always reacting to currently floor types and changing conditions.

So what’s new?

The upgraded part of this cleaning head is that it now includes polycarbonate teeth, which helps to prevent tangling around the bristles.

I could see this being really handy for pet owners or if you live with / are yourself long-haired people.

⭐ Hair Screw Tool (NEW)

The hair screw tool is a brand new tool, designed to replace the mini-motorized tool and offer better performance when cleaning pet hair or long hairs.

Dyson V15 Hair Screw tool

How does it work?

The conical brush bar works like an Archimedes screw, having a wide to narrow cross-section which twists as it cleans.

Dyson V15 Hair Screw tool

Using hair’s natural tendency to tighten & wrap, the decreasing diameter allows the strands to migrate towards the narrow end of the brush bar.

Also, because the brush bar is cantilevered the hair is threaded off the tip and sucked into the bin. 

Standard Attachments & Tools

In addition to the new tools listed above, the V15 Detect also comes with some of the standard tools that we’ve seen from other V Series Dysons.

Standard tools with this machine include:

  • Crevice Tool: This tool is longer than the combination tool and provides a narrower opening for capturing debris; great for in-between couch cushions, behind furniture, or other hard-to-reach spaces.
  • Stubborn Brush: This brush has bristles that are slightly further apart than the bristles of the dusting brush and they are also much firmer. This is a handy tool for scrubbing dirt from hard surfaces like floor tile or heavy-duty abrasive textiles.
  • Combination Tool: This tool provides the function of a short / wide crevice tool as well as a soft dusting brush. Its versatility makes it nice when cleaning indoor spaces like couches and furniture, as well as when cleaning your car.
  • Docking Station: The docking station provides a simple wall-mounted spot for your Dyson to hang when not in use. This accessory can also hold 2 accessories for easy access.
  • Charger: The charger plugs into a standard wall outlet and lets the Dyson juice up in between cleaning cycles.
  • Extension Wand: This wand is most frequently used when the V11 is in upright stick vacuum mode, but it can also be used to extend user reach when in handheld mode. The red button on the end can connect to a cleaning head or to any of the handheld attachments.
  • Wand Clip: stores up to two tools or accessories on-board attached to the extension wand

👍 Usability

The usability of the Dyson V15 is the best we’ve seen to date. As with most good products, when new models are released, they take the good features from the last model and add even more features.

Such is the case with the V15.

Some of the most impressive features that improve usability include:

Click-in Battery

Yes

Run Time

60 mins

Cleaning Head

Washable

Dust Bin Capacity

0.2 gal

Charge Time

4.5 hours

Cleaning Modes

Three

  • Click-in battery: makes it easy to remove the battery for quick charges in between uses or have 2 batteries and swap them out for longer run times
  • Up to 60-minute run time: can run for up to 60 minutes on the charge of a single battery
  • Washable Fluffy cleaning head: use warm water to rinse away stubborn debris that may get caught on the brushroll
  • Point-and-shoot debris canister: quickly empty the dust bin into the trash with a single button push
  • Charge time: fully charges in approx. 4.5 hours
  • Cleaning modes: includes 3; Eco, Auto, and Boost—modes with higher suction tends to also mean shorter run times

Getting Set Up

The Dyson V15 is quick setup and only takes a couple minutes to unbox and get the vacuum ready to clean.

Similar to what we’ve seen from other V-Series Dysons, the V15 uses the same click-in system, which allows all parts to snap together in one quick motion.

The Display Screen

The digital display is a huge part of the overall usability of the Dyson V15.

Dyson V15 display
Dyson V15 display

On-board sensors located internally on the V15 are designed to detect the count and size of the particles being cleaned up.

The system then sorts the particles into four different categories.

Allergens

>10µm

Dust / Skin

>60µm

Dust / Sand

>180µm

Sugar / Fleas

>500µm

  • (10µm) Particles the size of allergens and pollen: Pollen is commonly carried into homes on skin, hair, clothes, footwear, and pets. Once inside, pollen grains and antigens accumulate in house dust, reaching a peak concentration long after pollination season.
  • (60µm) Particles the size of microscopic dust and skin flakes: Molds measure up to 100µm and can be found around kitchens, windows, and other damp areas. Their spores can irritate the nose and throat, causing shortness of breath.
  • (180µm) Particles the size of dust mites and fine sand: House dust mites are one of the major indoor triggers for allergies and asthma. Each mite produces about 20 droppings a day, which continue to cause symptoms even after the mite has died.
  • (500µm) Particles the size of sugar and fleas: These larger, visible particles are trapped in the bin as soon as they enter the primary cyclone and metal mesh filter – clearing the airflow, so there’s no loss of suction.

How loud is the Dyson V15?

For this test, we use a sound meter to measure noise in terms of decibel level approximately 3′ away from the vacuum.

The Dyson V15 generates 71 to 76 decibels of noise, depending on the mode. Here are the exact results, by cleaning mode:

  • Eco mode: 71 dB
  • Auto mode: 74 dB
  • Boost mode: 76 dB

Ambient noise level in the room is around 40 dB. We used the High Torque cleaner head for all tests. The room we test in is all hardwood floors with a thin run and other living room furniture.

Maintenance

Maintenance on the Dyson V15 is similar to the other V-Series stick vacuums.

Emptying the V15 dust bin
Emptying the V15 dust bin

The most important maintenance tasks include:

  1. Regularly emptying the dust bin.
  2. Washing the filter each month (cold water, air dry for 24 hours)
  3. Replace the battery as needed.
  4. Wash the cleaning head as needed.

Dysons including the V10, V11, and V15 are all supposed to last up to 15 years, according to Dyson’s founder, James Dyson. This keeps the maintenance sots incredibly low and lets you focus on the other tasks.

With a lifetime washable filter and a battery that should last the life of the unit, it should cost effectively $0 / year in maintenance costs.

While the initial cost of the Dyson V11 vacuum is steep, the low maintenance costs do help to offset it.

Is the Dyson V15 a good value?

No doubt, the V15 Detect is expensive. But it’s also an incredibly high-performance bleeding edge machine.

If you are serious about having a high-quality, great-performing stick vacuum that makes it easy to know exactly how well it is cleaning then the V15 would be a fantastic choice.

Some of my favorite value adding features of the V15 include:

  • Laser light on the Fluffy cleaning head
  • Includes Fluffy head and Torque Drive head
  • Long 60-minute run time with click-in battery
  • Advanced digital display with full-color graphics
  • Three cleaning modes—Eco, Auto, or Boost
  • Internal sensors that automatically detect which type of debris needs cleaning

🥇 Summary

If you want the best that Dyson has to offer and want to know that you’re cleaning all of the debris, even that which is hard to see, the V15 is the best choice.

Who Should Buy the Dyson V15 Vacuum?

I would recommend the Dyson V15 if you’re looking for the following features in a cordless stick vacuum:

  • Absurdly Good Suction: The V15 Detect has an amazing 230 AW of suction power in Boost mode. This is the most of any cordless vacuum on the market.
  • Cleaning Heads & Tools: You’ve got the High Torque head, washable Fluffy head, upgraded mini motorized brushroll, and the standard set of accessories. The V15 Detect really takes the attachment and tools from Dyson to the next level.
  • A way to remove invisible debris: The V15 is one of the first vacuums we’ve ever tested that puts so much effort into making invisible debris such a priority. The laser light on the Fluffy makes it easier to see fine particles as you clean and the on-board sensors are constantly scanning in the background to improve performance let you know exactly what needs to be cleaned.
  • Advanced digital display: The digital display allows you to see the current cleaning mode, estimated remaining run time, and all of the data generated about the particles on your floor or other surfaces.
  • Automatic adjustments: The internal Piezo sensor automatically detects what kind of debris is on the floor and adjusting accordingly. In addition, sensors on the cleaning heads can also adjust for varying floor heights. Eco and Boost cleaning modes allow you to easily adjust the suction level manually or you can set it on Auto and let it adjust automatically.

    • You attached the wall mount with drywall anchor screws. Then you thread the power cord up the wall and through the back of the wall mount.

  1. Hi! When I put the vacuum on boost mode the roller head sometimes stops spinning. I have to move the vacuum back to get it spinning again. Is this normal? Or did I receive a defective unit?

    Reply
    • It’s normal. It’s a problem we’ve seen on a number of cordless stick vacuums, but especially if they have higher suction.

      It seems to only happen on certain carpet types. In our case, it mostly happens with a Ruggable rug that we have.

      Lower suction power and/or raises the front gates will help in the case of the V15.

  2. What is the + and – adjustment for on the High Torque Head? Just got my new V15 and it doesn’t mention anything in the online manual

    Reply
    • It raises / lowers the gates on the front of the brushroll. That creates a tighter or looser seal with the carpet.

      Tighter seal = more suction / better cleaning, but it also hugs closer to the floor, which can push larger debris forward.

  3. Thanks for your review, you are always very thorough!

    I have hardwood floors throughout the house and several large area rugs. So with two heads, one for carpet and one for floor, it seems we would have to change heads in each room. Maybe it is easier to do this than I might imagine … but it does not seem all that convenient to be dragging an extra head from room to room and swapping them. Or maybe you go through the house twice.

    I would appreciate if you could test to see which of the two heads would do the best job at handling both floors and carpets and share what you learn.

    Thanks!

    Reply
    • Thank you!

      That’s an easy one, if you don’t want to switch heads just keep the High Torque head on. That is the multi-surface cleaning head, it works on carpets and hard surface flooring.

      The Fluffy head is not intended for carpets.

      I think if you’ve got lots of hard surfaces or you just want to clean those specifically take a moment to switch on the fluffy head. If not, just keep the High Torque head on all the time. It’s going to do a fine job on all floors.

  4. Is the new Laser Slim Fluffy cleaner head backwards compatible with the v11 vacuum? It looks to be available for $120 on its own from Dyson.
