Today, we’re going to be looking at a side-by-side comparison of the Dyson V15 vs. V7. Are the newer features with the higher cost worth it? Or does the value of the V7 silence the bells and whistles of the V15?

Let’s dive in and find out.

Table of Contents

🧪 Performance

To really test out the Dyson V15 vs. V7, we looked at three different aspects of performance. And honestly, price aside, the V15 was the clear winner here.

Dyson V15 (bottom) vs. V7 (top)
Dyson V15 (bottom) vs. V7 (top)

Let me explain the breakdown:

  • Cleaning Tests: how well the vacuum sucks up debris
  • Suction Power: much much suction is generated from each vacuum
  • Run Time: how long the vacuum runs (with a full battery)

Here is how each vacuum performed during each test.

Cleaning Performance

WINNER: Dyson V15

For cleaning performance tests, we perform a total of 12 tests using four different debris types and three different flooring types.

ModelOverallHardwoodsLow CarpetHigh Carpet
Dyson V1599%100%99%99%
Dyson V796%89%100%100%

We test on engineered hardwoods, low pile carpet, and high pile carpet and against 4 debris types:

  1. Cereal (dry)
  2. Rice
  3. Kitty litter
  4. Sugar (granulated)

Overall Cleaning Scores





Dyson V15 Cleaning Performance

On hardwoods, the Dyson V15 was great and scored between 99-100% for all floor types. Honestly, it’s hard to do much better than that.



Low Pile Carpet


High Pile Carpet


For these cleaning tests, we used both the soft Fluffy roller cleaning head and the High Torque cleaning head.

Dyson V15 hardwood floor tests

One quick note to mention about cleaning carpet. On our first test (results not listed), we used the High Torque cleaning head on Boost Mode and it was actually a bit too much suction.

What we noticed when running the V15 on carpet and Boost mode is that the suction was so strong, it pulled too much on the carpet, and in turn, had worse cleaning performance.

Essentially, the cleaning head tended to push large debris instead of being able to get on top of it.

The fix?

To remedy this problem, we ran the carpet cleaning tests in Eco mode which decreased the max suction and increased overall performance.

Dyson V7 Cleaning Performance

The Dyson V7 also had good performance, but did struggle with cleaning large debris from hardwoods (hence the reduced cleaning performance on hardwoods).



Low Pile Carpet


High Pile Carpet


On hardwoods, we noticed that the V7 tended to just push around the cereal as well as the rice debris, instead of getting on top of it.

It was able to clean smaller debris like kitty litter and granulated sugar without issue.

Suction Power

WINNER: Dyson V15

Regarding suction, both the V15 and the V7 use a cyclonic system, which uses the power of fast-spinning rotation to create strong suction. Strong suction, in turn, translates into good cleaning performance.

The V15 can spin at up to 125,000 RPM and the V7 can spin at up to 110,000 RPM.

ModelMax RPMsMax Suction (AW)
Dyson V15125,000 RPM230 AW
Dyson V7110,000 RPM100 AW

In terms of suction power, that means that the V15 has over 2X the suction power over the V7. But bear in mind, both vacuums had great cleaning performance so the extra power of the V15 didn’t really make a huge difference during our tests.

Dyson V15 (right) vs. V7 (left) motor body
Dyson V15 (right) vs. V7 (left) motor body

Where the suction power is going to make a difference is for deep cleaning thick carpets. If your home has lots of carpet and/or thicker carpets the added suction can help to make a difference in those environments.

Run Time Performance

WINNER: Dyson V15

Run time revealed some pretty big differences between the V15 and the V7. According to Dyson, the V15 and V7 have the following estimated run times.

Dyson V15

60 mins

Dyson V7

30 mins

That’s a 50% longer run time on the V15 than what the V7 can offer. Both of these vacuums come with one battery so you’ll need to charge up after the run time is exhausted.

Dyson V15 (right) vs. V7 (left) brushrolls
Dyson V15 (right) vs. V7 (left) brushrolls

The V7 plugs into a standard wall outlet and the V15 uses a removable battery that clicks into the underside of the vacuum.

MORE: If you want an extra battery and twice the run time, splurge for the Dyson Outsize. Read our review here.

In addition to the manufacturer run times, we also decided to setup a few run time tests where we ran each vacuum in-house on all available cleaning modes.

Here’s what we found out:

Dyson V15

  • Eco: 68:30 mins
  • Auto: 45:30 mins
  • Boost: 8:55 mins

Dyson V7

  • Normal: 27:45 minutes
  • Max: 7:10 minutes

V15 Cleaning Modes

The V15 offers three cleaning modes.

  • Eco Mode: uses the least amount of suction and generates the longest run time
  • Auto Mode: varies the suction as needed, depending on floor type
  • Boost mode: uses the most suction and generates the shortest run time

V7 Cleaning Modes

The V7 offers two cleaning modes.

  • Normal Mode: uses less suction for a longer run time
  • Max Mode: uses more suction for a shorter run time

🧬 Design

The Dyson V15 and V7 have some design similarities, but also quote a few big differences as well.

Similarities include:

  • 2-in-1 stick vac or handheld
  • Quick-release attachment system
  • Trigger on/off system
  • Variable modes
  • Assortment of tools and attachments
  • Washable filter

Let’s dive a little deeper into these differences between these two Dyson models.

#1. Digital Display

Dyson V15


Dyson V7


There is a digital display on the back of the Dyson V15. This display is full color and shares some useful information about the vacuum as it cleans.

Shared info includes:

  • Cleaning mode
  • Estimated remaining run time
  • Maintenance alerts
  • Particulate data (more about this below)
Dyson V15 display screen
Dyson V15 display screen

What is particulate data?

Particulate data is a new feature, just launched with the V15. It uses a tiny on-board sensor to detect size and quantity of particles on the floor. Being able to detect these particles allows the vacuum to automatically adjust suction levels, depending on what type of particles are being cleaned.

The display on the back takes all of the super complex data from the sensor and displays it in an easy-to-read bar chat format.

Dyson V15 display

The chart tells you particle size and quantitiy of each size as well.

The Dyson V7 does not have a digital display or any ability to communicate particulate size.

#2. Piezo Sensor

Dyson V15


Dyson V7


This sensor ties into the particulate data above. The Piezo sensor is a small device designed inside the vacuum that makes all of the particulate data possible on the V15. The V7 model does not have this sensor.

#3. Cleaning Heads

Dyson V15


  • High Torque 2.0
  • Laser Slim Fluffy

Dyson V7


  • Direct Drive (all models)
  • Fluffy (V7 Absolute / Fluffy only)

The V15 comes with two cleaning heads and the V7 comes with one or two, depending on which model you go with.

So what makes each cleaning head unique?

High Torque 2.0 vs. Direct Drive

Dyson V15 High Torque head
Dyson V15 – High Torque cleaning head
Direct Drive cleaning head
Dyson V7 – Direct Drive cleaning head

Both of these cleaning heads are designed to be multi-floor cleaners that use a hybrid brushroll design that makes it efficient for cleaning hard surface or carpeted floors.

The High Torque 2.0 head with the V15 has a row of polycarbonate teeth that help prevent tangles. The Direct drive cleaning head is a bit more basic, but still uses a spiral blend of bristles and composite paddles to agitate and sweep debris into the dust bin.

Laser Slim Fluffy vs. Fluffy (standard)

Dyson V15 laser
Dyson V15 – Laser Slim Fluffy cleaning head
Dyson soft roller brush cleaning head
Dyson V7 – Absolute Fluffy cleaning head

The Fluffy cleaning head has two design iterations represented here—the Laser Slim Fluffy and the standard Fluffy.

The Laser Slim Fluffy head has a bit lower profile than the standard Fluffy and also includes a green laser light that shines on the floor.

The purpose of this light is to make it easier to see small debris as you clean. According to Dyson, it has no negative effect on battery life and can be turned on or off.

The Standard Fluffy head is a bit higher profile, but uses a similar design of soft roller brush to sweep the floor. As the name suggests, there is no laser light included with the Standard Fluffy cleaning head with the V7.

Also, as a quick note, not all versions of the Dyson V7 come with a Fluffy head at all. The Fluffy is only included with the:

  • Dyson V7 Absolute
  • Dyson V7 Fluffy

Both brushrolls are removable and washable for easier maintenance.

Allow it to air dry for 24 hours and then reinstall.

#4. Suction Power

We briefly discussed RPMs above and how the V15 and V7 compare. The V15 offers up to 125,000 RPMs while the V7 maxes out at 110,000 RPMs.

In terms of suction power, that translates to 230 AW of suction power with the V15 and up to 100 AW suction power with the V7.

Dyson V15

230 AW

Dyson V7

100 AW

The V15 is going to provide stronger suction and stronger pull against ground-in debris over the V7. But for cleaning hardwoods or low pile carpet primarily, I’m not sure the difference would be that noticeable. (See our cleaning performance data for V15 here and V7 here).

#5. Click-In Battery

Dyson V15


Dyson V7


The Dyson V15 has a click-in battery that is removable from the base of the vacuum. By comparison, the V7 model does not.

To charge the V7, you’ll need to plug the charger into the back of the vacuum and then plug the entire vacuum into a stadnard wall outlet.

Dyson V15

Click-in battery on the Dyson V15

The V15 takes about 4.5 hours to charge while the V7 only takes about 3.5 hours.

#6. Run Time

Dyson V15

Up to 60 mins

Dyson V7

Up to 30 mins

The estimated run time of the V15 is about twice the estimated run time of the V7. Those numbers are according to the manufacturer.

When we ran both vacuums on their most efficient cleaning mode (Eco for the V15 and Normal for the V7) we found that the V15 could run for around 68 minutes and the V7 could run for around 27 mins.

#7. Configuration

Dyson V15


Dyson V7


Next on the list, let’s talk about the configuration. Older Dysons (pre-V10) have a more traditional configuration, while newer Dysons (V10 and later) shifted to an in-line configuration.

The redesign of the airflow means newer models can offer:

  1. Stronger suction
  2. Larger dust bin capacity
  3. A new way to empty the dust bin
  4. Digital display
Dyson in-line configuration vacuum comparison

The V15 has the in-line configuration (bottom of image above) and the V7 has the more traditional configuration (top of image above).

When using the Dysons in handheld mode, the in-line configuration can sometimes feel a bit more awkward since it’s longer, while the traditional configuration is a little easier to manage, but you give up the nicer features like the digital display on the back and larger bin capacity.

#8. Dust Bin Capacity

Dyson V15

0.77 L

Emptying the Dyson V15 dust bin

Dyson V7

0.4 L

The dust bin on the V15 is about 30% larger and can hold about 1 cup more dry debris than the V7.

Size & Dimensions

Dyson V15

  • Length: 49.6″
  • Width: 9.8″
  • Height: 10.3″
  • Weight: 6.8 lbs.

Dyson V7

  • Length: 49.2″
  • Width: 9.8″
  • Depth: 10.1″
  • Weight: 5.45 lbs.

The size of the V15 and V7 models are similar, with the only main difference being the weight.

Dyson V15 (left) vs. V7 (right) sizes
Dyson V15 (left) vs. V7 (right) sizes

The V15 weighs over a pound more than the V7. I think part of that is thanks to the larger dust bin capacity, more powerful motor, and digital display in the back of the unit.

Both vacuums use standard width cleaning heads. If you want an extra-wide cleaning head, you’ll need to opt for the Dyson Outsize.

Accessories & Parts

The exact list of parts and accessories can vary depending on exactly which sub-model you go with.

There is currently only one version of the Dyson V15:

The Dyson V7 is offered in five different models, although some seem to be in the process of being discontinued, in lieu of newer model alternatives.

For stick vacuum use, attach the extension wand and then select a cleaning head.

How to pick a cleaning head?

  • Hard Floor Cleaning: For hard flooring like hardwoods, tile, or vinyl plank, the Fluffy cleaning head is a great choice. This head is available with the Dyson V15 Detect, Dyson V7 Absolute, and Dyson V7 Fluffy. However, the multi-surface brushroll is also suitable for hard surface floors.
  • Multi-Floor Cleaning: For cleaning area rugs, carpet, etc., the Torque Drive (on the V15) or the Direct Drive (on the V7) are better options. These cleaning heads are designed to agitate debris for better performance.

🥇 Which Dyson is Best?

For the best of the best, the V15 clearly takes the cake, but that’s not to say that the V7 isn’t good for some people.

If you don’t need all the bells and whistles (and don’t want to spend top dollar) the V7 can still check a lot of boxes and provide a quality clean.

Should you buy the Dyson V15 Detect?

I would recommend the Dyson V15 Detect to people who:

  • Incredible Suction & Cleaning Power: the V15 dominated our cleaning tests, removing 99% of all debris by weight. It has the most suction of any cordless vacuum on the market at 230 AW. Truly a bleeding edge machine.
  • Want particulate data: If you’re really interested in what exactly you’re cleaning, the Piezo sensor makes that possible by breaking down a series of particulate data and putting that data right on the digital display.
  • Advanced digital display: In addition to particualte data, the digital display also can share info like cleaning mode, remaining run time, and maintenance alerts. This data is all displayed on the back of the vacuum itself.
  • Laser brushroll: The Laser Slim Fluffy brushroll includes the green laser light that shines on the floor and makes it easier to see small debris. For more visibility, this is a pretty unique feature to have included with a brushroll.

Should you buy the Dyson V7?

I would recommend the Dyson V7 to people who:

  • Want a less expensive Dyson: If you like the design of a Dyson, but don’t want to pay the high price, the V7 is a good option. Five years ago this model was top of the line and it still has great cleaning performance and cool features.
  • Excellent cleaning performance: The suction is certainly less than that of the V15, but the performance was still fantastic. The only area where it struggled was large debris on hardwoods, but honestly, it includes a crevice tool that would just as effective at cleaning large debris messes.
  • Don’t need the extended run time: The V7 can run for up to 30 minutes which, although less than the V15, is still a decent amount of time for a cordless vacuum cleaner. If you can’t see yourself cleaning for a solid hour then it may be worth the savings to go with a vacuum that has a shorter time and pocket the cash.
