How this review was made: We did not test this vacuum in person. This verdict is based on our analysis of expert reviews, retailer review summaries and owner repair threads, all listed at the end of this article. Several expert tests date from the V8's launch years, so we lean on owner reports for long-term reliability. Our method.
Still a capable stick vac, but the battery is its weak spot
Reviewers consistently praise the V8's suction on carpet, rugs and pet hair, its light, balanced feel and its quick switch to handheld mode. A Best Buy Canada reviewer felt it could be a home's only vacuum. The trade-offs are real, though: Max mode lasts only about seven minutes, the bin is small enough to need emptying mid-clean, and owner repair threads show a common pattern of the vacuum cutting out after a few seconds as the battery or filter ages. It is a good buy if you accept a battery replacement down the road; if you want long runtime and a bigger bin, newer models fit better.

- have pets and mixed floors in a small or mid-sized home
- like switching to handheld for stairs, sofas and the car

- want a vacuum that will run years without a battery swap
The Dyson V8 is a cordless stick vacuum that converts to a handheld. Dyson rates its battery at up to 40 minutes, with a Max power mode for stubborn dirt, and it charges on a wall-mounted dock.
The V8 has been around for years, so there is plenty of owner feedback on how it ages. We pulled together expert tests and owner repair discussions and flag where the evidence is older.

How it holds up over time
Battery wear is the main long-term theme. In the iFixit discussion, many owners fixed the cut-out problem with a new battery, while others solved it by fully taking apart and cleaning the filters, including the cone-shaped one. Some received warranty battery replacements from Dyson. We found no rigorous multi-year lab data, but the pattern suggests budgeting for a battery at some point.
Tips from owners
- Use Max sparingly, only for stubborn spots.
- Wash and fully dry the filters regularly; clogged filters can cause shut-offs.
- If it cuts out, clean the filters first, then consider a battery or contact Dyson under warranty.
- Empty the bin before it is full on large jobs.
