facebook Dyson V6 vs V7 vs V8 Cordless Vacuum Cleaners: Whats...

What is the difference between the Dyson V6, V7 and V8 cordless vacuum cleaners?

Up until recently, cordless vacuums were viewed in a negative light because of their poor suction power, with many asking themselves should purchase a corded or cordless vacuum? But they have improved significantly in recent years.  If you want a to buy a cordless Dyson vacuum cleaner, it’s difficult to know where to start.  If you’re looking at the V6, V7 and V8, you are still faced with many decisions as there are over ten models to choose from across these three popular designs.  So, apart from the obvious, being the price, what’s the difference? There are some key features to consider, below.

Dyson Models:

The most obvious difference between the three types of Dyson is the different model variation.  The different models ultimately affect which accessories you get with your machine, and there are over ten different models.  Different models include the ‘Total Clean’, the ‘Animal’ and the ‘Motorhead’.  The Animal (available in V6, V7 and V8) is the version of Dyson that is tailored especially for those with pets, as the heads provided are ideal for picking up pet hair.  The different models do not necessarily affect performance, it’s more of personal choice for the buyer.  Ensure you check what accessories you get with each model and what their purpose is, as this will help you choose the design that is most suitable for your individual needs.

Difference between Dyson vacuum weights:

The Dyson V6 Cordless vacuum cleaner was not Dyson’s first cordless vacuum cleaner; however, it was the initial breakthrough model.  One of the benefits of having a cordless vacuum is that they are light-weight and easy to manoeuvre.  The V6 is slighter lighter than the V7 and V8.  The V6 comes in at 2.11kg whereas the V7 is slightly heavier at 2.3kg, and the V8 comes in at around 2.61kg, which is obviously heavier.  The 0.5kg difference between the V6 and V8 model can be a substantial difference for some people, especially if you are specifically looking for a light-weight product.

Difference in Dyson vacuum battery life:

Battery running time can be an influencing factor when buying a new model too.  There’s nothing worse than being mid-way through vacuuming your stairs, and suddenly, there’s no power.  The V6 can last up to 20 minutes, in comparison the V7’s 30 minutes.  The V8 has an added 10 minutes in comparison to the V7, totalling a maximum time of 40 minutes, that’s double the time of the V6 model.  Just bear in mind that these times are all without the motorised tool.

Charging times:

Charging time is often important when choosing a cordless vacuum cleaner.  There’s nothing worse than being half-way through whole-house vacuum and then you must charge your up your device for several hours.  Believe it or not, the V6 and V7 both charge quicker than the V8 cordless Dyson.  There is a huge variance between the charge time of the as the V6 and V7 have a charge time of 3.5 hours, whereas the V8 takes 5 hours to fully charge.  90 minutes added on to charge time is a significant difference considering that the V8 model only performs for 10 minutes longer than a V7 model.

Emptying systems:

A feature that the V7 and V8 have in comparison to the V6, is that they have the No-Touch Dirt Emptying System.  This is a notable feature if you don’t like to get your hands dirty and this is basically a clever little device inside that pushes out the dirt for you.  This means the V7 and V8 models are more hygienic models of cordless vacuum cleaner.


The filtration system is something that is sometimes overlooked. The V8 filtration system is much more effective than that of the V6 and V7.  The V6 and V7 are cyclonic, with a lifetime washable filter, but the filtration system in the V8 is much more advanced and this is much better for anyone who suffers from allergies.

Suction and Brush Bar Power Explained:

Let’s face it, we all want to know just how well our vacuum will pick up the dirt.  We want it to be the best, right? This is where suction power comes into the equation, as this can be another deciding factor when choosing from different cordless vacuum machines and models.  The V6 is said to be a powerful model of cordless vacuum cleaner, that cleans well.  The suction power of the V6 has a slightly stronger suction power than the V7. Now, it would be easy to think that the V6 would be better at cleaning up, but this isn’t necessarily the case.

Although the suction power for the V7 is slightly less than the V6, the V7 has 75% more brush bar power than the V6.  Brush bar power has a massive impact on performance and can mean a better clean overall.

Now in comparison, the V8 is said to have Dyson’s most powerful motor.  The more powerful the engine, the more powerful the clean, meaning it’s able to remove more dirt.  The model also has a ‘boost mode’ too, and with its more powerful direct-drive cleaner head, it certainly can deep-clean your carpets.

Dyson ranges performance comparison:

Comparing the models here based on performance is key to understanding each product.  The V7 models compare quite well because it has the same charging time as the V6 but runs for ten minutes longer.  The V6 takes 3.5 hours to be fully charged, for 20 minutes vacuuming time, so this is not ideal if you are planning a long vacuuming section.

The V7 takes 3.5 hours to be fully charged and you can vacuum for 30 minutes, whereas the V8 takes 5 hours to be fully charged, for 40 minutes vacuuming time.  The longer vacuuming time often makes a machine more appealing, because you don’t want it to run out of charge, mid-clean.  Although all these Dyson models have strong suction power, the V7 has a massive advantage due to its improved brush bar power.

The V8, on the other hand, has a much more powerful motor and a direct-drive cleaner, and this certainly gives it an edge when it comes to performance, even though charging time is quite extensive. The V6 and V7 models can now be bought with the direct-drive cleaner too.

Difference in Dyson vacuum prices:

Price is something else that we consider when buying a vacuum.  The Dyson brand is a popular brand in vacuum and this is reflected in the price.  You know sometimes you are paying a little more than other brands, but it’s typically worth it because of their performance reputation.  As you would expect, the V6 is cheaper and is currently retailing for a little under £200, whereas the V7 is just over the £200 mark.  The V8 is the newest model so this is obviously reflective in the price of this model.  Currently, to buy a Dyson V8 Cordless, you would be looking to pay a little over £300, but remember you are paying for Dyson’s strongest motor, and all the performance perks that the V8 offers.

Conclusion – Choosing the Right Dyson Vacuum:

Choosing the right Dyson Cordless design and model is certainly a personal choice and it depends on how you will use the vacuum and what you will use it for.  If you want a light-weight, high-performance, vacuum that you can nip around a small home reasonably quickly, then one of the V6 models is for you.

If you are looking for something that is still reasonably light-weight, vacuums longer and can perform a deeper clean, but isn’t overly expensive, then the V7 model is ideal.

For a high-performing, deep clean, with maximum vacuuming time then the V8 might be the model for you, providing you don’t mind the extra 1.5 hours charging time.  Many people want to get the vacuuming done in one go and if the vacuum is powerful enough, 40 minutes is often ample time run through a small family home.

Dyson certainly has something for everyone!
