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 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, Ive said it before and Ill say it again soft rollers are the future of hard floor vacuuming, they just can do things that vacuums without soft rollers cant and I really recommend soft rollers for hard floors.

With the 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 and V8 Motorhead only come with this one cleaner head.

So what we found is that while they both did good, they both had 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 I your home, and therefore no reason to change from the soft roller, then there is 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 large debris pickup 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 and the Dyson V8 has only a low and a high power.

So we see that the Roidmi F8 has just a little more suction than the v8 but the most important metric is airflow where the Dyson V8 had 48 cfm in its high power at the wand compared to 37cfm for the Roidmi, both of which are incredibly high numbers for a cordless vacuum by the way.

You can also see when we include the battery life numbers on each of these settings the Dyson V8 did 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, which I tested twice to confirm, and is probably the best battery life to cfm ratio I have 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 Roidmis handle has two different places to hold it, from the top or the side, which dramatically reduces strain when switching from vacuuming to handheld mode like for using the attachments.

With the dust bin the Dyson v8 has the definite advantage as it is more than twice the size, and its dramatically easier to empty a keep clear of debris.

The build quality is too close to call as both are top of the line vacuums and material quality and deign are excellent in both cases.
