Xiaomi Roidmi F8 vs Dyson V8

Today, we will be looking closely at the Roidmi F8 vs. the Dyson V8.

The runaway success of Dyson has spawned lots of copycats. Just do a quick search on Amazon for “cordless vacuum,” and you’ll know what I mean.

You’ll see a lot of products that are blatant rip-offs. The sad news is none of them can match the quality and performance except for a few brands like Shark.

Xiaomi has finally joined the cordless stick vacuum market with their latest product – the Roidmi F8 Storm.

Xiaomi Roidmi F8 vs. Dyson V8: Design and interface

Roidmi F8

In typical Xiaomi fashion, their stick vacuum comes in an all-white finish with some red accents. Fit and finish are excellent with all of the attachments locking in place with a solid feel.

You wouldn’t think that a Roidmi is a Dyson knock-off because they use a different design.

While it uses the same design principle with the motor and bin at the top, the design concept is different.

The bin orientation is similar to the Dyson V10 where it is horizontally aligned. The power switch is at the top of the ergonomic handle where you have easy access.

You don’t have to worry about continually squeezing a trigger because the motor stays on when you press the power switch.

To access the max suction mode, all you have to do is press the power button a second time. Turning it off is a bit tricky – you’ll need to hold the power button for a few seconds to power off.

Dyson V8

The Dyson V8 is much colorful than the Roidmi with shades of blue, gray, pink and orange.

Each variant will have a slightly different color scheme. All Dyson’s cordless vacuums use a trigger mechanism that you’ll need to squeeze for power constantly.

For earlier variants, the trigger wasn’t as soft which meant more effort. Newer options have more malleable triggers so finger and wrist fatigue won’t be as big of an issue.

Winner: Roidmi

Motor and power

Roidmi F8

According to Roidmi’s website, the F8 storm uses a DC brushless motor that spins at 100,000 rpm. It equates to around 115 air watts of power which is the same as the Dyson V8.

One big advantage of a brushless motor would be efficiency. Without going into the boring technical details, a brushless motor will last longer since there are less wear and tear and much more efficient.

It is impressive since a majority of the 2-in-1 cordless vacuums that resemble the Dyson does not come close to this type of power.

One gripe that I have with the Roidmi is the noticeable lag when you turn on the motor.

Not a big deal but it is worth mentioning for your information.

Dyson V8

All later generation Dyson cordless vacuums use their digital motor. The V8 utilizes Dyson’s V8 digital motor with the 2 tier radial cyclones that is one of the best at filtering fine dust particles.

It motor spins a little bit faster than the Roidmi’s brushless motor at 107,000 rpm.

However, Dyson does not disclose whether V8 digital motor is a brushless or a brushed motor.

Like the Roidmi, this motor also produces 115 air watts of power.

Winner: Even

Dirt bin

Roidmi F8

Roidmi’s bin has a similar orientation as the Dyson V10 where it is aligned horizontally with the motor behind it. One reason they did this was to increase the efficiency of the motor and filtration.

The downside to this design is the smaller bin size. The manufacturer did not specify the exact capacity of the bin, but it’s visibly less than that of the V8’s dirt bin.

Dyson V8

The Dyson V8’s bin isn’t what you consider significant, but when you put it side by side versus Roidmi, it’s visibly larger.

Dyson says that the V8’s bin can hold up to 0.14 gallons which are at the fill line. But it’ll still work way past it which easily doubles that number.

One obvious downside for both brands would be how messy it would be to empty.

If you are cleaning a lot of pet hair or dust, it’ll stick on the plastic walls and mesh shroud at the middle.

So you’ll have to disassemble the whole thing to get everything out.

Winner: Dyson V8

Floor tools

Roidmi F8

Unlike the Dyson that uses two separate tools that house the combo brush and soft roller bar, Roidmi only comes with a single floor tool with interchangeable brushes.

Out of the box, you’ll get two roller brushes – a soft roller bar and the combo roller brush.

The soft roller bar will work best on bare floor while the combo brush works well on carpet.

However, in my tests, I found that you can also use the soft roller brush on the carpet.

It was able to pick up at least all of the surface dirt on low pile rugs and carpet. One downside though I found with the Roidmi was the clearance.

Since it uses a single floor tool, clearance for both the soft roller bar and combo brush was the same.

It is one of the most significant advantages that Dyson has over other brands because the higher clearance (at least for the soft-roller tool) allows the bar to pull large piles of dirt towards the suction chamber.

It prevents the floor tool from pushing dirt forward.

Though Roidmi has a lower clearance, it did not plow dirt ahead as I had feared it would.

The soft roller bar did an excellent job of picking up dirt efficiently on both surfaces.

One feature that Roidmi has over the Dyson is the LED headlight that lights up on low light conditions.

It helps users track dust if visibility is poor.

Dyson V8

If you choose the high-end Dyson V8 Absolute, you’ll get both the soft roller bar and the direct drive (or combo brush) tools. These tools will work the best on bare floor and carpet respectively.

I’ve already mentioned this above, but one of the biggest advantages of Dyson’s soft roller bar tool is the amount of clearance it has.

The high clearance means more roller bar exposure which translates to better cleaning performance.

There will be less risk of this vacuum pushing or kicking dirt around except for the most solid debris.

Next floor tool available is the direct drive cleaning head which is Dyson’s version of the combo brush.

It tool combines soft carbon fiber and stiff nylon bristles that pick up fine dust and agitate carpet.

Both of these brands will do an excellent job at cleaning surface dirt and agitate to a certain degree.

But it will not deep clean carpet because won’t have enough power.

Winner: Dyson


Roidmi uses a four-layer filtration system that includes a mesh filter, cyclonic, HEPA filter and polymer sponge. All these combine to keep dirt and allergens inside the bin.

The exhaust blows to the side, so you don’t have to worry about air blowing on your face as you vacuum.

Dyson uses a similar system with a pre-motor filter, mesh, cyclones, and a post motor filter.

When it comes to filtration though, Dyson does a better job thanks to the better quality washable HEPA and pre-motor filters.

When you buy this, there are no filters to replace. Just wash the filters at least once a month.

Winner: Dyson

Battery and run time

The Roidmi F8 uses a high-performance LG lithium-ion battery that will run for as long as 55 minutes. However, if you turn on the max mode, run down will go down to only 10 minutes.

Dyson, on the other hand, uses a nickel-cobalt battery that will run up to 40 minutes. But if you use any of the motorized attachments, run time goes down to 25 minutes.

With the max function on, it goes down further to 8 minutes.

Winner: Roidmi

Tools and add-ons

Roidmi only comes with a couple of tools – the crevice and brush tool. So far the hose attachment and the mini-motorized brush still aren’t available in production models.

Dyson has far more devices that come in the package. If you opt for the top-end V8 Absolute, it will come with the following:

  1. Crevice tool
  2. Combination tool
  3. Mini turbo tool

There’s also an optional hose attachment if you need more reach and tight spot cleaning.

Until Roidmi releases more tools to their production line vacuums, Dyson remains the better option if you want versatility.

Winner: Dyson

Wall mount

Since both these stick vacuums can’t stand on its own, both come with a wall brackets that you can mount on the wall. Dyson comes with a bigger wall mount with a built-in charger.

Roidmi’s mount is much smaller and relies on a magnet rather than clips to hold it in place.

It looks much sleeker and futuristic, not cumbersome.

Imagine if the MacBook Pro had a wall mount, this is how it would seem.

Winner: Roidmi

Cleaning performance

To show you how both of these vacuums clean, I’ll share with you videos on how both perform.

First up is the Roidmi. I tried this on bare floor and low pile rug.

I don’t consider this a big mess test, but it’s a good gauge on what to expect from the Roidmi when cleaning hard floor and low pile carpet.

Onbare floor, it was able to pick up pretty much everything on there.

Performance on low pile rug is also pretty good as it was able to pick up at least the surface dirt.

Here’s a good cleaning test I found for the Dyson. The first video is a carpet cleaning test on what looks like low pile carpet.

Lastly, here’s a demo of the V8’s soft roller head on bare floor on different types of debris.

Performance on bare floor is excellent as the high clearance, and agitation from the soft roller bar pulls dirt.

On cleaning large debris like cereal, it will kick some of it, but most will go inside the bin.

Winner: Dyson (slightly)


All Dyson cordless vacuums come with a 2-year warranty. And if you purchase it from Amazon, extended warranties of up to 3 years is available for that extra peace of mind.

Roidmi only comes with a 1-year warranty, and GearBest does not have any extended warranties available.

The Dyson V8 Absolute is available in Amazon for less than $400. Since the release of the V10, the V8’s price has gone down, so it’s high time to take advantage.

If spending $400 is too expensive, you can opt for the cheaper V8 Animal that’s just a little over $300.

Roidmi F8 is available in GearBest for only under $300. You can use the coupon code below to get more savings.

To wrap up

The gap between Dyson and other brands has shrunk over the years. You cannot say that Roidmi is a cheap knockoff because it is well-made.

All the attachments are solidly built and locks-in place with an audible click. Run time is better with the Roidmi thanks to the high capacity LG lithium-ion battery.

My only gripe with it would be the small dirt bin and lack of attachments in the production model.

Dyson is a complete product with more tools which means better coverage and versatility. It also beats Roidmi in terms of warranty and fast shipping times thanks to Amazon.

If you don’t mind trying something new, then the Roidmi is a good option with a minimalist yet functional design.

It does not have a trigger switch so don’t have to squeeze something for it to run continuously.

But Dyson has a bigger bin and better warranty so there will be tradeoffs.

5 thoughts on “Xiaomi Roidmi F8 vs Dyson V8”

  1. It’s difficult to find direct comparisons between Dyson and the Roidmi F8 Storm (probably because the F8 is so new). This comparison is the best I’ve seen. Two questions:

    (1) You say “When it comes to filtration though, Dyson does a better job thanks to the better quality washable HEPA and pre-motor filters.” How did you determine that the Dyson filtration does a better job?

    (2) I’ve seen instructions online for replacing the Dyson battery when it wears out (even though it seems this is not officially supported). Do you know if the Roidmi F8 Storm’s battery is officially or unofficially replaceable?

    • Dyson’s filters are made from more dense fabric thus allow it to filter out more and there are two of them, one before and another after the motor. So this instantly doubles filtration, add to that the cyclones that provide an additional layer of filtration. Roidmi’s filter consists of foam and paper element that got pretty soiled after the cleaning test.

      As for the Roidmi battery, unfortunately it’s built into the body so it isn’t a plug and play thing.

  2. Thank you for this clear comparison. An important point to add (I think) is the noise level. The Dyson makes quite a lot of noise with 82dB, while the Xiaomi with 75dB is a lot more quiet.

  3. The Dyson V8 vacuum motor is also and brushless design and the battery chemistry is Lithium Ion.

  4. Dyson is noisy and hurts my ears.
    I can’t clean my car without it going flat… and I can only use it in short bursts which is annoying.
    Battery degrades very quick as in after 2 years, it required charging for 2 hours for 2min of usage.

    Motor is not brushless and the first V8 died and considering battery too, wasn’t worth fixing.
