The redesigned V8 keeps everything most buyers wanted from Dyson — sealed HEPA, anti-tangle brushroll and a confident detachable handheld — while dropping the price below $300 on sale. You lose the V15's laser, particle counter and 240 AW headroom, but the V8 cleans short-pile carpet and hardwood reliably for the cost of a budget Shark. It's the value-tier Dyson that actually delivers Dyson cleaning.
Full review
Cleaning Performance on Pet Hair
The most important V8 update for pet households is the new detangling Motorbar cleaner head, borrowed from higher-end Dysons. TechRadar's side-by-side review of the old V8 against the revamped 2024 V8 explicitly called the new head's anti-hair-wrap action a small upgrade that makes a big difference. Vacuum Wars confirmed the carpet pickup is fantastic, scoring it as able to pick up everything from fine dust to extra-large debris on low-pile. Long human hair still requires more attention than on the Dyson V15 with its Hair Screw conical tool, but the V8 ships a small Hair Screw attachment in the box for handheld pet-hair work on furniture and car seats. Overall the V8 is the budget Dyson that actually keeps up with pet-hair cleaning.
Hard Floor Performance
On hardwood the V8 has 115 air watts to work with, far less than the V15's 240 AW but enough for fine dust, crumbs and pet hair on a single pass. The Motorbar head's combined nylon-and-bristle design handles bare floors reasonably well, though there's no dedicated soft roller in the box like the V15 ships. Buyers with dark hardwood who want maximum dust visibility should look at the V15 for the laser-reveal head; the V8 offers no equivalent. TechRadar reviewers found the V8 handles typical apartment hard-floor messes (cereal, sand, pet kibble crumbs) on the first pass; on engineered hardwood the lower suction means slightly more scatter than the V15 produces.
Battery Life and Runtime
Dyson rates the V8 at up to 40 minutes; TechGearLab measured 33 minutes in low setting and only 7 minutes in high. Vacuum Wars confirmed 40 minutes at the lowest setting. That's enough for an apartment but tight for a 2,000-square-foot home. The battery is removable on the new V8 — a meaningful upgrade over the original V8 — so a spare pack is possible but adds about $100. Charging from empty takes roughly 4 hours. Boost mode is a true emergency tool here, useful for spot cleaning a specific spill rather than carpet sessions. For comparison, the Dyson V15 delivers 60 minutes Eco and the Shark Detect Pro 55 minutes — but at meaningfully higher prices.
Build Quality and Ergonomics
At 5.6 pounds the V8 is the lightest Dyson cordless and roughly a pound lighter than the V15 Detect. Reviewers consistently call out the ergonomics as a real strength, with a balanced wand that pivots easily and a confidently locking handheld conversion. Build quality matches the Dyson family — metal-jointed wand, no creaky plastic — though the LCD screen and trigger-lock features of the V15 are missing. The V8 still uses the hold-down trigger that critics dislike on the V15. Stair work is easier on the V8 than on heavier sticks like the V15 or Tineco S15 Pro, thanks to the lighter handle weight and similar mini-motorbar accessory.
Filtration and Allergens
Sealed HEPA filtration captures 99.99% of particles down to 0.3 microns — slightly less stringent than the V15's 0.1-micron sealing but still allergen-tier. The system is fully sealed end to end, with no air bypass around the filter. The washable pre-filter and post-motor HEPA are both standard Dyson parts and easy to maintain. For allergy households the V8 sits one tier below the V15 on paper but above the Shark Detect Pro and Tineco Pure ONE S15 Pro in terms of certification age and proven track record. The bin empties via the same lift-and-shoot lever, which kicks up some dust on emptying — less of an issue than the no-emptying convenience of the Shark auto-empty base.
Tools and Versatility
Four attachments ship with the revamped V8: the detangling Motorbar cleaner head, a combination tool, a crevice tool and the Hair Screw mini-tool for upholstery and stairs. That's a more generous accessory kit than the Shark Detect Pro base model, which ships with only a crevice tool. The handheld conversion is fast and the Hair Screw mini-tool is genuinely useful for car detailing — a feature the V15 also has. There's no dedicated soft roller for hardwood and no wall-dock kit included in the base box (it's a paid add-on on some configurations). Reviewers consistently rate the V8 attachment set as the best in the under-$400 cordless tier.
Where It Falls Short
The 115 AW suction is the visible gap between the V8 and the V15. Vacuum Wars and TechGearLab both flagged it as the V8's main limitation, particularly on high-pile carpet and embedded pet hair where the V15 cleanly outperforms. The 7-10 minute boost runtime is genuinely short — not a feature you can rely on for any extended deep-clean session. No smart sensor, no LCD, no adaptive suction mode means the V8 is a manual-control vacuum. The 0.53 L bin means more frequent emptying than the V15's 0.76 L bin. For some buyers these are deal-breakers; for others they're the right trade for a 60% price drop.
Who It's Best For
Choose the V8 if you want real Dyson build quality, sealed HEPA filtration and the new detangling Motorbar head at the lowest possible price — sub-$300 on sale, sub-$400 list. It's especially strong for apartments and smaller homes where the 40-minute runtime is enough and the 5.6-pound weight makes stair work easy. Skip it if you have high-pile carpet (the V15 cleans those visibly better), if you need a 60-minute single-charge whole-house session, or if you want the smart features (laser head, LCD, particle counter) the V15 ships standard. For pet-owning apartment renters the V8 is the highest-value Dyson cordless; for pet-owning homeowners the V15 is the better long-term investment.
How It Compares to Alternatives
The V8 sits as the cheapest Dyson cordless in current production, and the comparisons fall out cleanly. Against the Dyson V15 Detect the V8 trades roughly 50% less suction, 33% less runtime, no smart sensors and no laser head for a 60% lower price. Against the Shark Cordless Detect Pro the V8 has more raw suction and a more rigid build but lacks the auto-empty base and weighs more at the handle. Against the eufy HomeVac S11 Infinity the V8 wins on brand reliability, filtration certification and cleaning consistency, while the eufy counters with two batteries in the box for longer total runtime. Against the Tineco Pure ONE S15 Pro the V8 is a generation behind on smart features but ships with Dyson's longer reliability track record at half the price. For first-time cordless buyers wanting a brand-name vacuum that will last, the V8 is the safest pick at this price.
Long-Term Durability and Value
The V8 platform has been in market since 2016 — the longest reliability history of any vacuum on this page. The 2024 redesign refreshed the floor head and handle but kept the proven motor and cyclone architecture. Long-term reviews regularly cite V8 vacuums still running well at 5-7 years, with the most common end-of-life issue being battery capacity loss rather than motor failure. The new V8 uses a removable battery (a meaningful upgrade over the original), so a spare or replacement pack adds 3-4 years to the practical life. Dyson's 2-year warranty matches the V15 and S15 Pro and is shorter than Shark's 5-year. At $299 list (often $249 on sale) and a likely 7-10 year useful life, cost-per-year sits around $30-45 — the lowest per-year cost on this page for a brand-name cordless, which is the V8's strongest argument.
