Dyson V7 Vs V8 - Whats The Difference And Which To Buy?

So, why don’t we take a quick look at how the V8 and V7 work around the home?

Carpets.Both of these models use the Direct Drive floorhead. This sports a long brush bar with two rows of bristles. These are both hard and soft so that they can tackle hard floors and carpets alike without being too rough or too gentle.

This cleaning head is actually really effective at cleaning and working out surface dirt and grime.

The main issue with cordless vacuums like these is that they lack the deep cleaning abilities of a corded vacuum cleaner. The V10 and Dyson V11 rectified this, and while you will still get excellent cleaning results from both the V7 and the V8, it won’t quite be a deep clean.

Our Low-Pile Carpet Test Results

The test involves us taking a load of chilli flakes, flaxseed, loose black tea, and cheerios and weighing them to make sure we have 100g. These represent the textures found in the home and are then spread over a 1.5m strip of carpet. The vacuum is then run over the area for 10 seconds in each setting, the contents weighed, and the percentage recorded in the table below.

V8	V7
Low Setting	98.6%	99.3%
Auto Setting	n/a	n/a
Boost Setting	99.3%	99.53%

As you can see, both vacuum cleaners actually did really well. Interestingly, the V7 actually performed better than the V8, which isn’t necessarily expected considering the lower price point.

Hard Floors.The Direct Drive cleaning head can be used on hard floors, and it will do a good job of collecting large debris as well as larger clumps of dust. The soft bristles are gentle on hard floors and will not leave scratches, but it’s also not the most effective tool. Instead, it is a better idea to use the Fluffy cleaning head.

This is a large soft roller, and it has been specially designed to deal with hard floors efficiently and without any damage. It is the master of fine dust collection, and crevices are no match for it. Even large debris can be handled effortlessly and without being pushed around or spat back out.

Our Hardwood Floor Test Results

The hardwood floor test is performed under the same conditions as the carpet test, but we used a strip of laminate flooring instead as this is the most common hard floor in the UK. The table below shows the cleaning results.

V8	V7
Low Setting	100%	100%
Auto Setting	N/A	N/A
Boost Setting	100%	100%

We also used the Fluffy floorhead for this test as it is made for hard floors. As you can see, the results for the V7 and the V8 are identical.

Dyson V7 and V8 Stairs

A cordless Dyson is ideal for the stairs because they can be transformed into handheld vacuum cleaners. This makes everything more convenient, and you can attach the main surface cleaning head to the body of the vacuum, or you can use one of the other accessories. The best one to use for stairs is the mini motorised tool because it is basically a smaller version of the Direct Drive head.

This can be used to give the stairs a good clean, bringing up old dirt and muck that has been stomped into the carpet over time. This little tool can also be used on stubborn areas of regular carpet, on your furniture, and even the interior of your car when it needs a good clean.

Our Pet Hair Tests on Dyson V7 and V8

We collected 100g of dog hair and combed it into a five-foot strip of low pile carpet. Once this was done, we performed a 20-second pass over the area on each power setting to see how much hair was collected. The contents were then weighed to see the percentage.

We also went over the low pile carpet with a window blade after to see what was left behind. The good news is that both did very well in this regard, and nothing noticeable was picked up afterwards.

V8	V7
Pet Hair Pickup (Eco/Low)	90%	90%
Pet Hair Pickup (Auto/Medium)	n/a	n/a
Pet Hair Pickup (Boost/High)	99.9%	99.5%

The V8 and the V7 are quite evenly matched, and the V8 only wins by a fractional amount. This is reassuring for those who are thinking of picking up a V7 but worried about how effective it’s going to be on pet hair.

Eco mode is pretty poor, but this is normal for any vacuum cleaner. You shouldn’t really be using the lowest setting for collecting pet hair, and so you cannot expect it to do a great job.

Dyson V7 and V8 Filtration

This is where things get a little interesting. The V8 has the standard Dyson filtration system, which uses a HEPA filter to capture allergens and other irritants so that the air being pushed back out is cleaner. It also means that 99.97% of muck is taken out of the air, which is what makes it so good for allergy and asthma sufferers.

Now, the Dyson V7 Animal is the same as the rest of the Dyson vacuum cleaners in terms of filtration, but the other models are not. These use Lifetime filters instead. These are way less effective and do not leave the air as clean as other Dyson models. If you suffer from asthma and allergies, it is best to stay away from anything other than the Dyson V7 Animal.

The V8 has a fully sealed system, which means no dirty air is able to escape from little gaps in the vacuum cleaner. This is how it pushes such clean air back into the home. The V7 is sealed, but not fully, and there is still room for dust and grime to make its way back into the home. The Animal is more effective, but watch out for the others.

Our Filtration Test Results

We use special international approved dust from DMT in this test, and the air in the room is checked before and after we spend 15 seconds sucking it up with each vacuum cleaner. Our findings are then recorded in the table below, where you can see the V8 is far superior.

Dyson V7 and V8 Noise levels

Both of these models run under the EU allowance of 80dB. This means that they aren’t going to be deafening and you will be able to perform morning and evening cleaning tasks without the neighbours or family members losing their minds. However, there is a pretty clear winner out of the two with regards to noise levels.

The V7 is the loudest of the two, and it is several decibels higher than the V8 in both settings. The difference is definitely noticeable, and in the highest mode it is really climbing up towards that maximum. If you want a quieter machine, the V8 is your best bet.

Our Noise Test Results

For this test, we had the vacuum cleaners in their full form because this is the most common way they are used. We then placed a decibel metre three feet away from the main floorhead and let the vacuum run. The results were then recorded in the table below.

V8	V7
Low Setting	62.2	65
Auto Setting	n/a	n/a
Boost Setting	71.7	74
