Vax Blade 4 Classic Cordless Stick Vacuum Cleaner

Vax sells it on its official site, and UK retailers such as Marks Electrical and Euronics have stocked it too, so it's worth comparing retailers on price and availability. At either end of that range, the Blade 4 Classic includes a removable 4.0Ah battery, washable multi-cyclonic HEPA filtration and a 3-year parts-and-labour warranty covering the battery — features generally in line with a mid-range cordless stick vacuum. Vax's own site records an average rating of 4.4 out of 5 from 5,202 reviews, though this is a manufacturer-hosted figure rather than independent test data. Stock and pricing can change quickly, so confirm current availability before deciding where to buy.

Up to 45 minutes on standard settings with the included 4.0Ah battery, dropping to around 12 minutes if Boost Mode is used throughout — figures that align with Which? testing referenced by UK retailers. Full charging takes about 3 hours. The removable battery is compatible with Vax's larger 8.0Ah ONEPWR pack, sold separately, for extended runtime beyond the standard 45 minutes, though no price for that upgrade pack is published. At 3.1kg with the battery fitted (dropping to roughly 2.5kg without it, per manufacturer notes), the vacuum stays manageable to hold for most of that runtime, including on stairs once converted to its handheld mode using the included crevice and stair tools.

Yes. It uses washable, multi-cyclonic filtration with a HEPA filter, and Vax describes the suction as "fade-free", though no independent lab data accompanies that description in the available spec sheets. Being washable keeps ongoing filter costs at zero across the 3-year parts-and-labour warranty period, which is a genuine saving compared with vacuums needing disposable filter replacements. This filtration works alongside a 0.7L bagless bin (some retailers list 0.6L), so larger debris loads mean emptying and rinsing the filter more often than with a bigger-capacity model. HEPA filtration plus a removable 4.0Ah battery is a reasonable combination for a mid-range cordless stick vacuum.

3.1kg with the 4.0Ah battery fitted. Without the battery, the unit is approximately 2.5kg according to manufacturer notes, meaning the removable battery itself accounts for roughly 0.6kg of the total weight. This sits in the "standard" weight band for cordless stick vacuums, not the lightest available, but manageable for most people, including on stairs once the machine is converted to its handheld mode. It measures 1145 x 240 x 195mm, and the same battery that adds this weight also powers up to 45 minutes of runtime on standard settings, or as little as 12 minutes in Boost Mode. A heavier 8.0Ah ONEPWR battery is available separately for extended runtime, though it isn't included at this weight or price.

A 3-year parts-and-labour guarantee that includes battery coverage, though the full 3-year term requires registering the product on the Vax website. Battery coverage is a meaningful inclusion given the removable 4.0Ah battery is central to the vacuum's up-to-45-minute runtime, and batteries are typically the component most likely to degrade over a multi-year period. This warranty applies whether you buy direct from Vax or through retailers like Marks Electrical and Euronics. Registering promptly after purchase ensures you get the full 3 years rather than a shorter default period, so it's worth doing as soon as the vacuum arrives.

No. This model has no self-emptying dock and no app control — it's a manually operated cordless stick vacuum, consistent with its positioning as a mid-range rather than premium option. There's also no wet-and-dry function or mop combo mode, so it's a straightforward dry-vacuum-only stick cleaner rather than an all-in-one system. The 0.7L bagless bin (0.6L per some retailer listings) needs manual emptying, and the washable HEPA filter needs manual cleaning too, though both keep running costs low since there are no bags or disposable filters to buy. If self-emptying convenience or app control matters to your decision, it's worth comparing other Vax models or cordless stick vacuums that include those features.

0.7 litres in most UK retailer listings, though some sources state 0.6 litres, so treat the exact figure as approximate rather than fixed. Either way, this is a compact bin that will need frequent emptying on larger homes, particularly across a full 45-minute runtime on the standard-mode battery setting. It's a bagless design, so there's no ongoing bag-replacement cost, and the washable HEPA filter inside means no separate filter-replacement expense either. Given the vacuum weighs 3.1kg with its 4.0Ah battery fitted, emptying the bin regularly also helps keep the machine light and manageable during use rather than letting debris add unnecessary weight before you empty it.
