Introduction to the Dyson V7 vs. V8
The Dyson V8 was once Dyson’s flagship option, chosen as the “best” cordless vacuum in numerous publications. This Dyson cordless was the first to have the hygienic system and was a considerable upgrade over the V6’s trap door design.
The V7 came out soon after the V8. I believe Dyson did this to address the needs of the more budget-conscious homeowner looking for a less expensive alternative to the V8.
It has a smaller battery than the V8, so it doesn’t run as long. However, cleaning performance isn’t far off, especially on carpet.
The V7 model I have is the MotorHead with only the MotorHead attachment that works best on carpets.
Note: If the Dyson V7 or V8 is too expensive, then have a look at Tineco cordless stick vacuums. I’ve written an in-depth comparison between Dyson and Tineco; please check the link to learn more.
Dyson V7: Lighter, Better at Cleaning Smaller Spaces
One thing I like about the Dyson V7 is its compact frame. Even if the size difference in the spec sheet isn’t significant, the V7 feels much lighter than the V8.
Of course, there are tradeoffs to take into consideration. First is the run time. Since the V7 has a smaller capacity battery, it won’t run as long as the V8.
In my test with the MotorHead tool, it only ran for only 27 minutes – around 4 minutes less than the V8.
The V7 has several different sub-models; for more details, please check the V7 review.
All V7 options have the same motor and battery. The difference would be the tools, and if it had a post-motor HEPA filter.
Choosing the sub-model will be dependent on the type of flooring you have at home.
For example, homes only with hard floors will benefit from the V7 Fluffy since the Soft Roller attachment works best on this type of surface.
For wall-to-wall carpeting, the MotorHead would be the better choice. In homes with mixed surfaces, the V7 Absolute is an excellent alternative.
Dyson V8: More Power, Better Inside Larger Homes
The Dyson V8 has a larger battery and motor than the V7, which enables it to run further and deep clean better for longer stretches.
I have the Absolute variant that comes with the Fluffy and Direct Drive head, so it provides more versatility than the V7 MotorHead.
The Absolute version can clean hard floors and carpet as it has the Fluffy and Direct Drive attachments.
It will run for up to 41 minutes with non-powered tools and up to 31 minutes with the Direct Drive attachment, so the range is decent.
The Dyson V7 and V8 are very similar in terms of design – both having the same interface.
Each utilizes a slide switch for toggling between the default and max settings.
You can use the tools of the V8 in the V7. Yes, their tools are interchangeable, just an FYI.
The first difference when it comes to design is the size. As you’ll see in the photo above, the V8 is slightly bigger.
Another difference is the battery status. The V8 has a three LED indicator that informs users when the battery is at the 33% level mark.
While the V7 only has a single LED indicator, so it’s impossible to gauge how much battery life is remaining.
I use an anemometer to measure the amount of airflow that passes through these areas – the wand and cleaning nozzle. It’s an excellent barometer to check how a vacuum performs. Models with high airflow tend to do better at picking up debris on carpet.
Here are the results.
|Wand||29.64 CFM||49.68 CFM|
|Cleaning head||26.28 CFM||37.92 CFM|
|Wand||31.34 CFM||54.24 CFM|
|Cleaning head||26 CFM||36.95 CFM|
The difference is only minimal in the default setting. You’ll notice in the chart that the V7 has almost as much airflow at the wand and nozzle.
However, the gap widens in the max setting – as much as 8.77% difference at the wand in favor of the V8. Strangely, the V7 has 2% more airflow at the cleaning nozzle.
The results in the airflow test are consistent with the cleaning experiments as the V7 does surprisingly better on carpets, which we’ll go into next.
How does the Dyson V7 and V8 clean?
There isn’t much difference in the way each vacuum cleans since both have similar design cues.
One difference is the number of tools. The V8 Absolute has more tools than the V7 MotorHead, as it comes with the mini-Turbo brush and soft dusting brush that the MotorHead lacks.
You can purchase the V7 Absolute if you want more tools while still taking advantage of its more compact design.
Of all the Dyson cordless vacuums, these two are the best utilized as handhelds due to their smaller stature.
The V8 Absolute comes with the Fluffy and Direct Drive tools that work exceptionally well on hard floors and carpets, respectively.
In contrast, the V7 MotorHead only has one cleaning head – the MotorHead, which has excellent pick up on carpets.
Here’s a side-by-side comparison between the Direct Drive and MotorHead tools.
You’ll notice the Direct Drive having more bulk, which makes it resistant to tangles better than the thinner brush of the V7.
Cleaning performance comparison
Now to the meat of this comparison, the cleaning tests. First, let me share with you the results.
|Model||Dyson V7||Dyson V8|
|Hard Floors (Surface Test)||81.75%||99.66%|
|Sand on Hard Floor||99.2%||99.5%|
|Carpet (Surface Test)||99.97%||97.29%|
You’ll notice from the table, the V7’s hard floor performance is in the low 90s. It’s skewed by the low score with the Quaker oats test. Aside from that, it did well in other trials.
However, the V8’s soft roller attachment is superior to the MotorHead as it’s more efficient, sweeping up most of the debris in the initial pass.
Which is better on hard floors?
If you’re only comparing the V8 Absolute and V7 MotorHead, the nod goes to the V8 since it has the Fluffy attachment.
However, that won’t be the case if you’re getting the V7 Absolute or the Fluffy that has the Soft Roller tool.
One reason I prefer the Fluffy is it has better padding; thus, it lessens the risk of scuffing hardwood surfaces significantly.
Sand on hardwood comparison
Predictably, the V8 Absolute did better in the sand on hard floor test with a 99.5% score. Note that this is the average of two trials from the Fluffy and Direct Drive attachment.
- Dyson V8 Absolute: 99.5%
- Dyson V7 MotorHead: 99.2%
However, the V7 isn’t far behind with a 99.2% score. Even in the default setting, the V7 was able to pick up most of the sand in the forward pass.
Though, there was a portion left behind after the first pass. Some of the debris stuck on the “Ball” steering, which can scratch the surface. So it’s something to contemplate if your home has soft, easily scratched hardwood.
Edge cleaning comparison
There isn’t much difference between the V7 and V8 cleaning edges. All vacuums were able to pick up most of the debris on the sides and quarter-inch crevice.
Here’s the result of the V7 cleaning edges.
Conversely, the Fluffy tool was the most efficient as it was able to pick up the most with the least amount of splattering behind the brush.
Bear in mind that rollers are much better than traditional beater bars when cleaning hard surfaces.
Carpet cleaning comparison
Next, we’ll move over to how the Dyson V7 and V8 did with cleaning carpets.
|Model||Dyson V7||Dyson V8|
|Carpet (Surface Test)||99.97%||97.29%|
One surprise from the tests was the V7 MotorHead outdoing the V8 Absolute, at least with surface debris.
It was able to pick up an average of 99.97%, a few percentage points higher than the V8 at 97.29%.
The results back the airflow test scores where the V7 logged higher marks than the V8 in the max setting using the main cleaning head.
It was one of the biggest surprises thus far in this comparison.
However, in the deep cleaning test, the V8 was able to pick up more with a 97.7% score versus the V7’s 94.93%.
Large debris comparison
The presence of the Fluffy tool makes the V8 Absolute better at sweeping large debris like Fruit loops and Cheerios. In contrast, the V7’s MotorHead attachment will not pick up these types of rubbish.
It also didn’t do well with cleaning a large quantity of Quaker oats on hard floors.
The V7 did better on carpets, picking up this pile of Quaker oats, Cheerios, Fruit loops without any snags.
Likewise, the V8 is also capable of picking up large and extra-large stuff on carpets. So both are even in this category.
Hair wrap comparison
For the hair wrap test, I used one gram of five to seven inch human hair, which I scatter on a test area. I then run the vacuum to check how much wraps around the brush.
So I did tests on hard floors and carpets, and here are the results.
Only this much wrapped around the V8’s Fluffy tool.
The Direct-Drive fared much better with hardly any wrapping around the brush.
Now, let’s look at how the V7’s MotorHead did on hard floors.
And how it did picking up hair on the carpet.
There wasn’t much that wrapped after the hard floor test. However, much more enveloped on the brush on carpets.
I’m not sure why. Perhaps it was the friction that impedes the rotation of the brush. Whatever it is, I’m just sharing the results of the test.
So based on this, the V8 would be the better choice when it comes to cleaning hair.
Tools out of the box
The V8 Absolute has more tools out of the box, with a total of 8 if you include the two nozzles. It has the mini turbo brush and the soft dusting brush, which is absent in the V7.
- Fluffy tool
- Direct drive tool
- Mini turbo brush
- Soft dusting brush
- Combination tool
- Crevice tool
- Docking station
- Extension wand
The V7 Motorhead has fewer tools with only the combination and crevice tool to complement the main cleaning nozzle.
- Crevice tool
- Combination tool
- Extension wand
- Docking station
If you have pets, the V8 would be a better choice since it has the mini turbo brush that is more proficient at tackling pet hair on fabric upholstery.
Are the Dyson V7 and V8 attachments interchangeable?
Yes, the tools of the V7 fit with the V8 and the other way around. In case you can’t find a specific device from the V7 selection, then a V8 tool will be compatible with it.
Most tools in the Dyson cord-free product line are interchangeable except for the V6 and the Outsize.
Run time comparison
The V8’s larger battery enables it to run further than the V7.
Check the table below for the run time test results.
|Non-powered||32:43 mins.||5:45 mins.|
|Cleaning head||27:58 mins.||7:07 mins.|
|Non-powered||41 mins.||7:23 mins.|
|Cleaning head||31:33 mins.||8:31 mins.|
The V8 will run for as much as 41 minutes with the crevice tool. And up to 33 minutes using the Direct Drive attachment.
In contrast, the V7 can only last for 32 minutes with the crevice tool and 27 minutes with the cleaning head.
So the V8 is a better option if you’re looking to clean a larger home.
Can you replace the Dyson V7 and V8 battery?
One misconception many have is you cannot replace a Dyson cordless battery. That isn’t true even if the V7 and V8 don’t have a clip-on battery, replacing itis doable using a Philips screwdriver.
Please check this guide on how to replace the battery of the Dyson V8. The same process applies to the V7 as it has the same bolt placement.
Dust bin comparison
The V7 and V8 have identical dust bins. Both utilize the same hygienic system with a red lever for releasing dirt over a trash container.
Emptying contents won’t differ much.
However, the V8’s capacity is slightly larger at 0.54 liters versus the 0.53 liters of the V7.
The Dyson V8 Absolute has two filters – one pre-motor filter in the middle of the cyclones plus a HEPA filter behind the motor.
In contrast, the V7 MotorHead only has one filter – the pre-motor filter with the same placement as the V8.
The HEPA filter provides additional filtration keeping fine allergens from escaping. If this is a priority, then the V8 is the better alternative.
To measure noise, I used a sound meter to gauge loudness from a few feet away with the cleaning head attached. Here are the results.
|Model||Dyson V7||Dyson V8|
|Low||64.1 dB||62.8 dB|
|Max||73.9 dB||73.2 dB|
Surprisingly, the Dyson V7 recorded higher decibel levels in both the low and high settings.
Both vacuums score high marks with ergonomics. I like how the primary floor nozzles of each model are capable of sharp turns and avoiding furniture. The compact design helps immensely in cramped spaces.
Between the two, the V7 is the more nimble option. The smaller battery frees up the excess weight and gives it a lighter steering feel, particularly on carpets.
Inside smaller homes with lots of carpets, the V7 is ideal. It won’t clean embedded stuff as well as the V8, but its less straining on the arm.
Upkeep for both the V7 and V8 are similar. You’ll need to clean the filters at least once a month. Realize that Dyson cord-free vacuums come with a lifetime filter. So there’s no need to replace it for the lifetime of the vacuum.
Nonetheless, to prevent any downtime, I would suggest purchasing at least an extra set of filters, so you have something to utilize while the filter is drying up.
There are many options on Amazon – you can opt for an OEM replacement or an original. My preference would be going for a Dyson filter for longevity.

Which offers the better value?
The Dyson V8 offers several advantages over the V7. First, it runs longer thanks to the larger capacity Li-ion battery. In my tests, it ran for as much as 41 minutes with the crevice tool and 33 minutes using the Direct Drive attachment.
Second, it does better at picking up embedded sand from carpets. Third, the Fluffy attachment enables it to clean hard floors better than the MotorHead tool of the V7.
Nonetheless, the V7 performed better overall than the V8 in the surface cleaning tests on carpets. I’m not sure if it’s a fluke, but just sharing the results of the experiments.
5 Reasons to choose the Dyson V8 Absolute
- Better on hard floors: The Fluffy attachment of the V8 Absolute is superior over the V7’s MotorHead brush. It’s more efficient and isn’t as prone to scratching the surface.
- Runs longer: The larger capacity battery allows the V8 to run further. So it’s a better alternative for bigger homes.
- More tools: It comes with more attachments than the V7 MotorHead.
- Deep cleans better: Based on my tests, the V8 does better at picking up embedded dirt than the V7.
- Better at resisting tangles: The chunkier brush in the Direct Drive head resists tangles better than the thinner brush of the MotorHead.
4 Reasons to choose the Dyson V7 MotorHead
- Lighter: The V7 is the lighter option, so it doesn’t feel heavy on the wrist.
- Better Ergonomically: Being more slightly compact makes the V7 better when it comes to ergonomics. The steering is more responsive on carpets where the smaller brush has less drag.
- More airflow: One of the surprises is the V7 having more airflow than the V8, at least in the max setting using the primary cleaning nozzle.
- Cleans surface dirt better on carpets: The V7 scored 100% in seven of the eight tests and was a few percentage points better than the V8.
The Verdict: Is Dyson V8 better than V7?
On paper, the Dyson V8 seems to be the better product than the V7. It has more suction, a larger battery, and more tools.
However, the V7 had better results with surface cleaning on carpets. It’s one of the most surprising findings from the experiments I did.
The V7 Motorhead is a viable option inside smaller homes with lots of carpets where run time won’t be much of a factor.
There’s also the option of getting the V7 Fluffy for people who live in homes with hard surfaces and don’t want to spend more for the higher-end V8
The V8 Absolute is the better all-around option and suited for bigger homes with a mix of hard floors and carpet.
It’s the more expensive option, but that’s the tradeoff for getting a cordless vacuum with more tools and a bigger battery.
