Dyson builds the stronger, better-filtered cordless hoovers, but Vax gets you most of the everyday cleaning for roughly half the money. At around £250 the Dyson V8 and Vax ONEPWR Blade 4 are a genuinely close call; above £350 Dyson pulls clearly ahead because Vax has no flagship stick to match the V11 or V15.

Where the two brands overlap

Dyson's current UK range runs from the V8 at the bottom through the V11, V12 Detect Slim and V15 Detect to the Gen5detect and newer flagships. Vax lives lower: the Pace and Blade 4 are its core sticks, with Dual (two-battery) bundles as the step up. That means only two tiers really overlap: the £200–£300 entry Dyson against Vax's best stick, and the £300–£400 bracket where a discounted V11 meets a Vax Dual bundle.

Above that, Vax simply does not compete. If you are weighing a V15 Detect, your real alternatives are Shark's Detect and PowerDetect lines, covered in Shark vs Dyson.

Specs side by side

Figures are manufacturer claims; runtimes are in the lowest mode with a non-motorised tool. Check current prices, as both brands discount often.

Suction and cleaning

Dyson's advantage is most obvious on carpet. The V11's 185 air watts (AW) and torque-driven head lift embedded dust and hair from mid-pile and deep carpets better than the Blade 4, and independent consumer testing has generally rated Dyson's carpet pick-up higher at each price tier. Air watt figures are not the whole story (see suction power explained), but the gap is real.

At the entry tier the difference is smaller. The V8 is an older design with less suction than the V11, and the Blade 4 Pet holds its own on short-pile carpet, rugs and hard floors. On hard floors both are fine; Dyson's Fluffy soft-roller head, included on some V8 and V11 bundles, is better at fine dust on wood and tiles.

Hair tangling favours neither brand strongly at this level. Older Dyson heads and the Blade 4's brush roll both need occasional hair cutting, unlike Shark's anti-wrap designs or Dyson's newer de-tangling heads on the V15 and later.

Battery and runtime

This is Vax's win. ONEPWR packs click out in seconds, fit every Vax ONEPWR product and are reasonably priced as spares. The Dual bundle gives you two from the start, which comfortably covers a large house.

The V8 and V11 use screw-fixed batteries. They are replaceable and Dyson sells them, but you cannot swap mid-clean. The V11's longer runtime (around 60 minutes claimed, often 25–40 minutes with the motorised head in Auto or Medium) makes up for much of that. The V8's real-world 15–25 minutes with the motorised head is its biggest weakness in a family home; see our Dyson V8 review.

Bin and filtration

Dyson's whole-machine filtration is a real advantage for allergy sufferers. Dyson claims its sticks capture 99.99% of particles down to 0.3 microns, and its sealed design means less fine dust escapes around joints. Vax uses washable filters that are good for the price, but it makes fewer whole-machine sealing claims. More detail is in our HEPA filters guide.

Bins are similar in size. Dyson's point-and-shoot emptying is quick but can be messy with long hair. Vax's bottom-opening bin is equally simple and slightly larger than the V8's.

Ergonomics

The V8 is lighter and better balanced than the Blade 4, which makes it nicer for stairs, cobwebs and handheld jobs. The V11 is heavier at the top, and the trigger-only control on both Dyson models tires some hands on long sessions. Vax also uses a trigger. Neither brand includes a bending wand like Shark's Flexology.

Tools, parts and warranty

Dyson's tool range and click-in system are the most extensive on the market, and original parts are easy to buy direct. Vax's tool set is smaller but covers the basics, and Pet versions add a motorised mini tool. Dyson gives a 2-year guarantee on its cordless machines; Vax typically offers 2 years, sometimes more with registration. Both sell batteries and filters direct.

One practical difference: older Dysons are widely available refurbished, which is a good way to get a V11 at Vax-level money. See our refurbished cordless hoover guide.

Price and value

At £200–£300 the Blade 4 is the better-value buy for most homes, particularly if you want a second battery. At £300–£450 a discounted V11 is the better hoover outright, and Vax has no answer for deep-carpet performance at that level. If you are only spending £250 and want a Dyson, the V8 is a reasonable choice for smaller, mostly hard-floored homes.

Who should pick which

One more practical point: Vax's wet-and-dry Glide cleaners share the ONEPWR battery, so a Blade 4 plus a Glide gives you two machines and one charging routine. Dyson's wet floor cleaner, the WashG1, is a separate cordless machine with its own battery and costs considerably more. If washing hard floors is on your list, see best cordless wet and dry hoovers.

Final recommendation

Buy the Vax ONEPWR Blade 4 Pet if your budget stops at around £250 or you want the Dual battery bundle. Stretch to a Dyson V11 if you have plenty of carpet, pets or allergies; it is the point where Dyson's extra cost clearly shows.
