The new ROIDMI F8 Storm cordless vacuum was released recently in the United States and it’s often been compared to the Dyson V8 so I thought it would put them both through a series of tests to see which is the better vacuum and which is the better value.
Let’s start with the features. Both the Dyson V8 Absolute and the ROIDMI F8 Storm come with two cleaning options: a soft roller for hard floors and a standard brush roll which can do both hard floors and carpets but is better for carpets. In the case of the ROIDMI, the soft roller is interchangeable on the same cleaner head. And in the case of the Dyson V8 Absolute, you change the entire cleaner head.
The ROIDMI F8 features include an app which shows stats on the cleaning time and filters, a low, medium, and high power setting, a very good attachment set including a crevice tool/ dusting brush, a crevice tool hose combo, an extremely high quality powered pet tool, and an innovative magnetic charging dock.
The Dyson V8 features include a two-level power setting: low and high, a very cool bin emptying design which reduces mess, it also has a great attachment set including a crevice tool, a combo tool, a high quality mini motorized attachment, a soft dusting brush, and a wall-mounted charging dock.
They both get big points in my book for being sealed systems with HEPA filters which is great for allergy sufferers. This is a feature only found in high-end cordless vacuums and is therefore more rare than you might think. So with the cleaning ability, we tested them in both low and high power and with both types of cleaner heads on carpets and hard floors.

With the soft rollers, we found virtually no difference in that they both were amazing with everything from fine debris to pet hair to large and even extra-large debris. I’ve said it before and I’ll say it again. Soft rollers are the future of hard floor vacuuming. They just can do things other vacuums can’t and I really recommend soft rollers for hard floors.
With a standard brush roll, we needed to test their performance on carpets as well as hard floors since the standard brush roll is very often used for both surfaces. In fact, most versions of the Dyson V8, like the V8 Animal or the V8 Motorhead, only come with this one cleaner head.
So what we found is that, while they both did good, they both have their strengths and weaknesses. For example, the ROIDMI standard brush was in general better with larger debris on carpets but especially on hard floors where the Dyson V8 struggled very much with larger debris. But the Dyson was slightly better with deep cleaning carpets as we saw with the black carpet fine debris test.
So I would say that if you have all hard floors in your home and therefore no reason to change from the soft roller then there’s virtually no difference in the performance of either of these vacuums. But if you have a mixture of carpets and hard floors and you don’t want to change out the roller then it depends on if you value larger debris pick up more or deep cleaning carpets more.
Next up is power and battery life. So we tested the suction and airflow at the wand and at the cleaner head and these are the results. Keep in mind that the ROIDMI has a low, medium, and high power and the Dyson V8 only has a low and a high power.
So we see that the ROIDMI F8 has just a little more suction than the Dyson V8 but the most important metric is airflow where the Dyson V8 had 48 CFM in its high power at the wand compared to 37 CFM for the ROIDMI, both of which are incredibly high numbers for a cordless vacuum, by the way.
When we include the battery life numbers on each of these settings, the Dyson V8 does slightly better, but again, both of these vacuums represent the tip top of the line in terms of battery to CFM performance. The only anomaly here is that the ROIDMI, for some reason, gets almost as much battery life in its 31 CFM medium power than it does with its 24 CFM low power. I tested this twice to confirm it, and it’s probably the best battery life to CFM ratio I’ve seen so far. But for some reason, the medium power on the ROIDMI F8 is only accessed through the app.
Both the Dyson V8 and the ROIDMI F8 Storm are very light and easy on the forearm with the only difference being that the ROIDMI’s handle has two different places to hold it, from the top or from the side, which dramatically reduces the strain when switching from vacuuming to handheld mode, like for using the attachments.
With the dustbin, the Dyson V8 has the definite advantage as it has more than twice the capacity and it’s dramatically easier to empty and clear of debris. The build quality is too close to call as both are top of the line vacuums and material quality and design are excellent in both cases. So I think that about covers it.
