The cordless vacuum market in 2026 is dominated by Dyson, with Shark, Miele, and a handful of newer brands competing on value. The honest finding from testing four of them across two UK homes for two months: the Dyson V15 Detect is genuinely the best, the Shark Stratos performs at 80-85% of that level for half the price, and most UK households would be perfectly happy with the Shark.
The Dyson is what to buy if money isn't a meaningful constraint. The Shark is what to buy if it is. Anything below £150 is what to swerve.
The four worth knowing
Dyson V15 Detect at £550-£650. The cordless vacuum benchmark for several years. Strongest suction of the four, laser detection (genuinely useful — you see dust you'd otherwise miss), 60-minute battery on lower power (15 minutes at max), strong attachment system, 5-year warranty. Heavy versus alternatives — wrist fatigue on long sessions.
Shark Stratos Cordless at £280-£380. Competes with Dyson at lower price. Anti-hair-wrap brushes that genuinely work — particularly useful for households with long hair or pets. Suction competitive with the Dyson V15. Lighter than the Dyson. Build quality slightly trails Dyson; battery is removable but only one included.
Miele Triflex HX1 at £500-£600. Best build quality of the four. Unusual three-in-one configuration that adapts to floor and high cleaning. Premium experience. Miele filtration is genuinely excellent for households with allergies.
Halo Capsule at £200-£280. Compact, lightweight cordless designed for smaller flats and hardwood-heavy homes. Genuinely useful for the use case; not a full-house vacuum for carpet-heavy homes.
How I'd actually pick
Most 3-bed households: Dyson V15 Detect if budget allows; Shark Stratos if budget tight. The £250 difference is real but the Shark performs at 80-85% of the Dyson's level, which is a defensible trade for many households.
UK households with severe allergies: Miele Triflex HX1. The filtration matters here.
Flats and hardwood-heavy homes: Halo Capsule is sufficient.
UK households on tight budgets: don't buy a sub-£150 cordless. Better to spend that money on a corded Henry vacuum at £90, which lasts essentially forever and outperforms cheap cordless models on raw cleaning ability. The cordless premium is real; the cheap cordless premium is illusory.
A note on cordless versus corded
The honest truth that no cordless marketing will tell you: a £90 corded Henry will outclean a £200 cordless on carpets, especially over the lifespan of the products (Henrys last 15-plus years; cheap cordless 2-3). The case for cordless is convenience, not raw cleaning power.
If you have stairs and carpet: the convenience of cordless is real and worth paying for. If you have hardwood and one floor: a corded vacuum or a £200 cordless is fine. Pick by your actual home, not by what looks good in adverts.
