Dyson V6 vs V8: A Detailed Comparison Guide

When Dyson introduced the world to the DC series, it changed the world viewed cordless vacuums.

It brought in suction and versatility never before seen in a cordless.

A lot has changed since the first Dyson DC35 entered the fray.

Dyson has improved upon that original design with subsequent releases and the V6 and V8 are currently the best in terms of performance and features.

We’re going to have a close look at these two closely, more specifically its features, differences and performance.

Oscar Wilde said that “imitation is the highest form of flattery”. And Dyson’s success has bred a lot of imitators. The Shark Rocket and Hoover Cruise are two such products that come to mind.

These products have incorporated parts of Dyson’s blueprint like the removable wand, trigger switch and interchangeable tools.

But none of these products can match Dyson’s combination of portability and power.

Sure a Shark Rocket may have more power but that’s because it has a cord. A Hoover Cruise is cordless but it doesn’t quite pack the punch.

Introducing the Dyson V6

When Dyson first unveiled the V6 series, it totally changed the way people think about a cordless.

No longer could people say that it had weak suction and totally useless.

Compared to the 2nd generation DC44 it had nearly twice as much power in max mode.

Regardless of power, the V6 had never-been-seen-before tools that aid it in cleaning floors.

The V6 first introduced the soft roller cleaner head. This tool has revolutionized the way bare floors are cleaned.

No longer will a stiff bristle risk scratching expensive hardwood flooring or create a bigger mess.

Both of these variants have this tool along with the bristled attachment for cleaning carpet.

It’s this versatility that makes a Dyson unique. Forget about deep cleaning for a moment here, what I’m talking about is portability like no other product can provide.

What are the Improvements in the V8?

Aside from the obvious improvements in power and run time here are two major improvements that make the V8 a better product compared to the V6.

Improved Bin

Two design flaws held the V6 back. This is based on consumer feedback.

The first flaw would be the bin design. Dyson advertises this as being easy to empty.

When you see advertorials, it shows dirt dropping with ease. But in reality that isn’t always the case.

If your household chores involve cleaning a lot of dust, emptying the bin will also involve some cleaning up of its own as well.

What do I mean?

According to Wikipedia, statically charged dust likes to cling to other objects because of static electricity. In the case of the V6 dust sticks on the plastic shell and inner filter of the bin. Both of these are made from plastic.

And when it’s time to empty, these types of debris don’t just fall off. It stays inside the bin and you will need to use your fingers or disassemble the whole bin in order to clean it thoroughly.

See what I mean?

Dyson has improved the design in the V8. Instead of just relying on a door and gravity, the new design actually pushes dirt out, at least most of it.

Even with all the muck and hair inside, it has a mechanism that pushes stuff out. Another area of improvement would be the placement of the lever.

The V6’s lever is in front of the trigger.

This is a pretty awkward position when you’re trying to empty it.

The V8’s lever is on top just behind the cyclones. To empty, all you need to do is pull up the lever. I feel that this is a better design because it offers more access for cleanup should any bits of dirt remain.

New Max Switch

Another improvement would be the max button. In variants prior to the V8 (this includes the V6) turning on the max function involves pressing a small button located at the back of the post-motor filter.

Nothing wrong with the placement but getting it to turn can be tricky. You’ll have to apply a bit of pressure to get it to work.

The new design eliminates that nuance. It uses a slide switch that makes the process much easier.

Now let’s compare all the features…


The Dyson V6 has the V6 motor that pumps out 24 air watts in normal mode. In max mode that number goes up to 100 air watts.

Just to give perspective on this, a full sized Dyson upright will have around 270 air watts on tap.

A hundred is pretty darn good considering this machine does not have any cords. It nearly produces more than a third the power a Dyson Ball Animal 2 would.

The Dyson V8 comes equipped with the latest V8 digital motor that produces almost 20% more power than the V6 motor. It has the same 2-tier radial cyclones that capture fine dust and allergens. A post-motor HEPA filter keeps those allergens inside the bin.

Winner: Dyson V8

Cleaning Performance

Cleaning on flat surfaces does not only require sheer power but you will need some sort of agitation to pull up dirt. This is specially true when cleaning dusty areas.

The Dyson V6 and V8 have tools specifically designed for bare floor and carpet. You’ll see in these videos the cleaning performance of both…

V6 demo on tile and carpet…

You’ll notice at the carpet test that the V6 still used the older cleaning head that had less agitation. The newer brush found in the V6 Animal and Absolute will provide better performance because it has more agitation.

And here’s a demo for the upgraded cleaner head…

In a single pass at normal mode the new cleaner head in the Absolute was able to pick up all the pet hair.

Here’s a demo of the soft roller cleaner head (or fluffy tool) on hardwood…

This proves that agitation plays an important role for cleaning on both surfaces. It’s not just raw power. Agitation was good enough to pick up even dust in the cracks.

Now let’s move over to the V8. Fine dust is perhaps the toughest type of debris to clean off carpet and you’ll how the V8 handle’s it…

The V8’s direct drive cleaner head is perhaps the best in the industry.

Here’s another video comparing the V8 to other vacuums cleaning powder on a tile with a deep crevice in the middle…

Only the V8 was able to pick up all of the powder scattered even inside the crevice.

Both of these variants come with a fade-free lithium ion battery but the V8 has a much longer run time of 40 minutes compared to 20 minutes of the V6.

The 40 minute run  time can only be achieved minus the motorized tools attached. If you attach any of the powered tools (e.g. soft roller cleaner head), that run time goes down to 25 minutes which is still plenty for spot cleaning.

Winner: V8


Both the V6 and V8 have HEPA filtration. Its filters are washable and will last the lifetime of the vacuum so you don’t have to worry about running costs.

Winner: Even


The V8 is slightly heavier at 5.75 pounds. The V7 is lighter at 5.1 pounds.

Winner: V6

Bin Volume

With the new bin design of the V8, Dyson was able to increase capacity to 0.14 gallons. This is around 0.03 gallons bigger than the V6.

Winner: V8


All Dyson cordless vacuums come with a 2 year warranty.

Tools and Attachments

If you check out Amazon, the V6 has a total of 10 variants, each with its own set of tools for a specific purpose.

As an example the V6 Mattress was created for mattress cleaning. It comes with a mini-motorized brush for the job.

Other tools in the package include a crevice, combination and soft dusting brush tools.

The first two is pretty standard in all variants.

At Dyson.com, the V6 has 4 variants – Total Clean, MotorHead, Cord-Free and HEPA. Not as diverse as the Amazon selection but still gives you options.

The first two have the improved direct-drive motorized brush. It provides 75% more agitation compared to the older cleaner head found in the Cord-Free and HEPA variants.

So far the V8 has only one variant in Amazon – the Absolute. It has the full set of tools that include the direct-drive cleaner head, soft roller brush, crevice tool, combination tool, mini-motorized tool and soft dusting brush.

Comparing the top variants both these variants come with the same number of tools. The biggest difference would be the motorized tools of the V8 that has more agitation.

Winner: V8 (slightly)

Where to Buy

Currently there are 4 different V8 options in Amazon. The V8 Absolute is the most expensive and is a great option if you have both bare floor and carpet. If you don’t need the bare floor cleaning soft roller head then opt for the cheaper V8 MotorHead with only the direct drive head.

Dyson V6 has around 9 different variants in Amazon. Read this article to get a detailed overview on how these differ from each other.

If you live in the United Kingdom, you can buy the V8 Absolute from Amazon’s UK site.

The Dyson V6 is also available from Amazon’s UK site and the options include the Animal, Flexi, Top Dog, Fluffy and Total Clean.

To Wrap It Up

You can’t go wrong with either of these two products. Both offer a level of versatility and power I’ve yet to see in another cordless vacuum.

The Dyson V8 is no doubt head and shoulders above every cordless vacuum when it comes to versatility, power and features. No other cordless touches it in sheer power and agitation it brings to the table with the two motorized tools in its toolset.

However all that high-tech gadgetry comes at a price.

The V6 is a good option if you don’t want to spend over $500 for a cordless.

The top of the line variant will cost a few hundred dollars less. It has a total of 10 different variants in Amazon that comes with a specific tool set each designed for a specific need.
