Vax Blade 4 Review: Is This the Best Budget Cordless Vacuum in the UK?
Cordless vacuums have a reputation for forcing a trade-off: pay flagship prices for genuinely good suction, or save money and put up with weak performance and a battery that dies halfway through the living room. The Vax Blade 4 has built its reputation on proving that trade-off wrong, and after digging into how it actually performs, it’s easy to see why it’s become one of Vax’s best-selling models.
The Quick Take
The Vax Blade 4 (part of Vax’s ONEPWR range) is a genuinely capable cordless vacuum built for small to medium UK homes that want reliable everyday cleaning without paying premium-brand prices. It brings strong multi-cyclonic suction, a swappable battery, and a generous accessory bundle with the trade-offs mostly showing up in refinement rather than raw performance. https://amzn.to/3UsdZUg
What’s in the Box
One thing that sets the Vax Blade 4 apart from similarly priced rivals is just how much comes in the box as standard. You get a powered floorhead, a crevice tool, a dusting brush, and a wall mount, a fairly generous starting kit compared to competitors that charge extra for attachments. The floorhead also includes LED headlights, a small but genuinely useful touch for spotting dust and debris on darker flooring or under furniture.
Suction and Cleaning Performance
This is where the Blade 4 earns its “does everything most homes need” reputation. Multi-cyclonic suction handles everyday crumbs, dust, and pet hair confidently across both carpets and hard floors, and a Boost mode is available for a deeper clean when you need it some testers have found Boost mode can be almost too powerful for lightweight rugs, which says more about how much headroom it has than anything else. The 0.6-litre dust container is larger than many similarly priced competitors, meaning fewer stops to empty it during a full clean.

Battery Life and the ONEPWR System
Battery life sits at up to 45 minutes on standard power comfortably ahead of several similarly priced rivals and even some pricier competitors. What makes this genuinely useful in practice is that the battery is detachable and swappable, part of Vax’s wider ONEPWR platform. That means not being tied to wall-mounting the vacuum directly next to a socket, and the option to buy a spare battery for longer sessions without a mid-clean charging break. A full charge takes roughly 2–3 hours, which is reasonable for the category.
Design, Weight, and Manoeuvrability
At around 2.8 — 3.1kg depending on the exact model variant, the Blade 4 sits in a comfortable middle ground light enough for everyday use, though it can start to feel heavy during longer handheld sessions like cleaning a car interior or stairs. It converts from upright stick to handheld mode easily, which extends its usefulness well beyond floors. One design quirk worth knowing: the fixed tube design means you can’t steer the floorhead by tilting your wrist while it’s flat against the floor, the way you can with some rival models, which makes manoeuvring around furniture legs slightly more effort than it needs to be.
Where It Falls Short
No vax cordless vacuum review would be complete without the honest trade-offs, and there are a few worth knowing before you buy:
- No HEPA filtration. The CleanAir filtration system traps general dust well, but allergy sufferers who specifically need HEPA-certified filtration may want to look elsewhere.
- No standalone charging dock. You’ll need to wall-mount it or find a safe spot for it to lean, rather than it self-parking like some pricier models.
- Emptying can be fiddly. The dust container sometimes needs a hand inside to clear stubborn debris rather than emptying cleanly with a shake.
- It’s on the louder side. Not the quietest cordless vacuum on the market, particularly in Boost mode.

Vax Blade 4 vs the Competition
Against pricier rivals like the Dyson V11, the Vax Blade trades a bit of outright refinement and battery runtime for a noticeably lower price and for most everyday cleaning needs, that trade is a sensible one. Compared to similarly priced competitors, the Blade 4’s larger 0.6-litre bin and swappable battery are genuine advantages, even if it can’t quite match premium-brand build polish. If you’re shopping specifically in the sub-£250 vax blade cordless category, it remains one of the strongest all-round options.
Final Verdict
The Vax Blade 4 delivers exactly what its reputation suggests: dependable, no-nonsense cordless cleaning without the premium price tag. It won’t out-refine a flagship Dyson, and allergy sufferers or anyone wanting a self-standing dock may want to look elsewhere but for small to medium UK homes that want strong suction, a swappable battery, and a genuinely useful accessory bundle, it’s hard to find better value in this price bracket.
