Dyson V8™ Cordless Vacuum

Many users describe the Dyson V8 as a genuinely impressive cordless vacuum, with some calling it the best all-around vacuum I've ever had and others going as far as saying the v7/v8 is the best designed vacuum ever . Users frequently praise its convenience of being cordless combined with powerful suction , and the ability to use it as a handheld vacuum is regularly highlighted as a practical bonus. Fans also note it cleans up the hair from dogs like nothing else and that the ability to vacuum dust from beds and sofas is remarkable .

The single most repeated complaint across reviews is battery degradation. Users report the battery dying or rapidly losing capacity over time, often leaving only 3–4 minutes of runtime after a couple of years. Beyond battery life, users flag the very small bin as a recurring nuisance, and the trigger-style operation that must be held down continuously frustrates many. A handful of users also raised serious safety concerns, with reports of the device catching fire .

The V8 earns particular praise from users doing quick cleans on hard floors , and those dealing with pet hair find it especially effective, with one user noting it works great cleaning up behind a cat . However, several users caution that it is not sufficient for carpet and that it functions better as a supplementary vacuum than a primary one, with one reviewer noting it does the job but is not something they recommend as a primary vacuum . The V8 with the Fluffy head works well for those with mixed floor types.

On value, opinions are sharply divided. Loyal users insist it is worth every penny and cite the best balance of weight and power relative to cost. But a vocal contingent considers Dyson typically overpriced and overrated , and with the cost of replacement or upgrades exceeding $800 , some question the long-term investment, especially given that cheap plastic parts degrade and batteries die after a couple of years .

Longevity is perhaps the V8's most divisive topic. Some users report remarkable staying power, with examples of the vacuum still going strong after 6 to 10 years , while others find it failing or becoming useless within 5 years . Dyson's after-sales support draws consistent criticism, with users reporting that Dyson support won't help or has discontinued support for the V8 , and the warranty period has been reduced from 5 to 2 years . Replacement batteries are an option, and some users note that replacing the battery made it work like new , though others warn that parts can be hard to find .
