[The In-depth Comparison]

Shark IONFlex vs Dyson v8

If you are looking for 2 in 1 stick vacuum cleaner, Shark IONFlex and Dyson V8 are the two best options in the market right now. For this reason, we wanted to make an in-depth comparison of these two brands.

These two brands have set a benchmark for the other vacuum cleaners. Their popularity among the customers is a major indicator of this.

Another important factor to consider is that they both are quite expensive. Therefore, you need to take extra precautions before purchasing high-end products like these.

Functional Design and Interface of Shark IONFlex vs Dyson v8

First of all, we will be looking at the interface and ergonomics of both the vacuum cleaners. In this section, we will discuss whether they are comfortable or not because there is no point in choosing a vacuum cleaner if you are not comfortable using it.

The motors of each of the variants are located on top of them – so bear in mind that the vacuum cleaner will be heavy.

As a result, cleaning your ceiling or above the floor will be a little tough and will require arm strength. But that is not the case for most situations as the machines are very light.

Each of the vacuum cleaners comes with dual speed settings. They also come with washable filters. But the way they work differs from one to another.

Dyson V8

Dyson v8 Functional Design and InterfaceThe V8 model uses trigger mechanism just like its cordless predecessors – DC35, DC59, DC44, V6, etc. in this mechanism, you will need to keep pressing a button/trigger to operate the vacuum cleaner.

Before V8, all the Dyson vacuum cleaners had a push button to turn on the max mode. It was a little irritating to turn it on and off continuously.

Customers had been continually complaining about the flaw in the design. As a result, taking the feedback into account, Dyson decided to launch the V8 model.

Now, instead of a button, V8 uses a slide switch for changing from normal to max mode.

Shark IONFlex

Shark IONFlex Functional Design and InterfaceBy the looks of it, Shark IONFlex looks pretty much like Dyson models. But the Shark was ahead of Dyson in many aspects. For example, the power switch in Shark is different than in Dyson models.

Dyson uses a trigger for turning the vacuum cleaner on. But Shark IONFlex uses a button for the main power switch and speed control.

The biggest advantage to this is – you don’t need to squeeze something to run the vacuum cleaner continuously. This feature is very useful when you want to clean your vacuum.

Vacuum Dust Cup Design and Capacity

Dust Cup Design and CapacityDyson V8 and Shark IONFlex – both have dust cups situated on the handle of the vacuums.

The dust cups in both the vacuum cleaners open up at the base so that dirt can instantly fall out.

Dyson V8 Dust Cup

The previous Dyson models were troublesome to clean because the dust cups depended only on gravity.

To fix this, Dyson V8 has featured a lever in the design. By pulling this lever, all the dirt that is holding onto the cup is pushed out.

Shark IONFlex Dust Cup

Shark features a simpler design in its dust cups compared to Dyson.

Shark IONFlex does not have any cylindrical filter which can keep the dirt in. So, by opening the base, all the dirt goes down at once.

Despite everything, Shark does have a smaller bin capacity – only 0.3 liters, whereas Dyson features a 0.5-liter dust cup. As a result, the dust cup gets full easily and you will need to empty the bin more frequently.

Runtime of the Shark IONFlex vs Dyson v8

Shark and Dyson both use rechargeable lithium-ion batteries in their vacuum cleaners. The V8 model can operate for up to 40 minutes. But that’s a case only when you are not using any motorized tool. The runtime can drop down to 25 minutes or less if you’re using soft roller brush or other motorhead tools.

And as for Shark IONflex, it can run for 46 minutes when fully charged. But that level also drops down to 25 to 30 minutes if you use DuoClean Head.

As you can see, the runtime for both the vacuum cleaners is almost the same. What makes all the difference is that Shark’s battery is removable, whereas Dyson’s is not.

It can be a big deal if your vacuum cleaner gets damaged.

Our personal opinion is that they both are great vacuum cleaners in terms of cleaning.

Vacuum Cleaner Warranty 

Warranty Every Dyson cordless vacuum cleaner provides 2 years of warranty.

But the Shark IONFlex actually provides five years of warranty. They also provide an additional 2-year warranty for the battery.

So, we don’t need to tell you which one is better if the warranty is considered, it’s obviously Shark.

Filtration System in the Shark IONFlex vs Dyson v8

The V8 model features a Whole Machine HEPA filter in it. It keeps the dust and allergens inside the dust cup so that your air stays clean.

On the other hand, Shark IONFlex features a foam filter. Although it is not as good as HEPA filters, it is washable. So, you can use the same filter for a long time without changing it.

Cost Comparison

Cost ComparisonAs we have mentioned earlier, both the vacuums are quite expensive as they offer premium service. The price difference is minor here. But Shark really has some innovative features that Dyson doesn’t.


Additional Vacuum Attachments
