Cordless Vacuum With Longest Battery Life: 8 UK Models Compared

How we compare cordless vacuum battery life

Every runtime figure in this comparison comes from the manufacturer's own specification sheet for that model, normalised into our vacuum cleaner dataset — not from independent lab testing or hands-on use by our team. Brands typically publish a maximum runtime measured on the lowest suction setting with a fresh, undamaged battery; actual runtime on carpet in a boosted or max-power mode is usually shorter, sometimes considerably so. Use the figures below as a starting point for comparing models against each other, and check the individual product page or manufacturer listing for the exact test conditions before you buy. Our guide to cordless vacuum battery life covers how runtime is typically measured and what affects it in daily use.

Cordless vacuums with the longest battery life

Out of the 44 cordless vacuums currently in our dataset, eight models have a published maximum runtime figure. Ranked from longest to shortest, here's how they compare:

Model	Max runtime (mfr spec)	Weight	Dual battery	Price (GBP, dataset snapshot)
Samsung Bespoke AI Jet Ultra	160 min	2.8 kg	No	£799.00
Shark Stratos IZ420UKT	120 min	4.07 kg	Yes	£499.99
Miele Triflex HX2 Pro	120 min	3.6 kg	No	Not listed in GBP
LG CordZero A9 Kompressor	120 min	2.7 kg	Yes	Not listed in GBP
LG CordZero A9T Ultra Tower	120 min	2.66 kg	No	Not listed in GBP
Tineco Pure One S12 Pro EX	100 min	1.68 kg	No	£449.99
Samsung Bespoke Jet AI	100 min	1.78 kg	No	£1,100.00
Tineco Pure One S70	95 min	3.07 kg	No	£219.00

On paper, the Samsung Bespoke AI Jet Ultra has the longest quoted runtime in this group at up to 160 minutes — roughly a third longer than the next tier of 120-minute models — and carries a 4.9-average rating from 33 ratings in our dataset. It's also the heaviest of the top three models and the second most expensive, so it suits someone prioritising uninterrupted cleaning time over low weight or price more than someone carrying it up and down stairs regularly.

Four models tie at a spec-sheet maximum of 120 minutes: the Shark Stratos, the Miele Triflex HX2 Pro, and two LG CordZero variants. Among these, the Shark Stratos stands out on confirmed UK pricing (£499.99), warranty length (5 years versus 2 years on the Miele and both LG models), and review volume — it has the most ratings of any model in this comparison, at 1,836, averaging 4.7 in our dataset snapshot.

None of these runtime figures amount to an absolute ranking of "best" battery life — they reflect what each manufacturer publishes, under conditions that can differ between brands. If uninterrupted runtime is your main decision factor, the 160-minute and 120-minute models above are the closest matches to that specific criterion in our current dataset.

Dual-battery and replaceable-battery cordless vacuums

Two models in this comparison are built around a dual-battery system: the Shark Stratos Anti Hair Wrap Plus Pet Pro Dual Battery and the LG CordZero A9 Kompressor. Dual-battery vacuums ship with two removable battery packs — you fit one, run it down, then swap in the second to keep cleaning without waiting for a full recharge. Because the packs are designed to be removed and swapped by the user, they're inherently a form of replaceable battery, which also matters if a pack eventually degrades and needs replacing on its own rather than the whole vacuum.

None of the single-battery models in this dataset — the Samsung models, the Miele Triflex HX2 Pro, the Tineco models, or the LG tower variant — are documented in our current specifications as having a separately purchasable replacement battery pack. That doesn't necessarily mean one isn't available; it means our dataset doesn't yet confirm it either way for those specific models. If a swappable or user-replaceable battery is a hard requirement, our guide to replacing a cordless vacuum battery explains what to check on any model before buying, including single-battery ones.

Is 60 minutes of runtime enough?

Every model in this comparison already clears 60 minutes on its spec sheet, with the shortest — the Tineco Pure One S70 — rated at 95 minutes. For context, a single charge in the 60–95 minute range is usually enough to cover a small flat or a full clean of one or two rooms without stopping to recharge; larger homes, multiple floors, or households that vacuum stairs and upholstery in the same session tend to benefit more from the 120-minute-plus tier. Bear in mind that real-world runtime drops if you use a motorised pet-hair head or a boosted suction mode for most of the clean, since manufacturers usually quote their longest figure for the lowest power setting. If you're still deciding between a cordless and a corded model for a larger home, our corded vs cordless vacuum comparison covers that trade-off in more depth.

Other specs worth checking alongside runtime

Battery life is only one factor. Weight ranges from 1.68 kg (Tineco Pure One S12 Pro EX) up to 4.07 kg (Shark Stratos) across this group — a lighter machine is easier to carry upstairs but sometimes trades off dust capacity or runtime. Bin capacity sits between 0.44 L and 0.7 L, meaning some of these models need emptying more often than others regardless of how long the battery lasts. All eight models in this comparison have a HEPA filter and are bagless; warranty terms range from 2 years (Samsung Bespoke AI Jet Ultra, Miele Triflex HX2 Pro, both LG models, both Tineco models) to 5 years (Shark Stratos, Samsung Bespoke Jet AI). Noise level is only recorded for four of the eight models in our dataset (74–87 dB), so it isn't a reliable point of comparison across the full list yet.

Data gaps and things worth checking before you buy

This is a curated view of a subset of our cordless vacuum dataset, and coverage isn't complete for every field on every model:

• Pricing for the Miele Triflex HX2 Pro and both LG CordZero models is currently recorded in EUR, not GBP, in our dataset. Confirm the UK price on the retailer's own listing before comparing it against the GBP-priced models above.
• Star ratings and review counts are only present for the two Samsung models and the Shark Stratos in our dataset; their absence for the LG and Tineco models reflects a data gap, not a judgement on those products.
• Prices, stock status, and ratings shown here are a snapshot from our dataset, not a live feed. Always check current price and availability on the retailer's page before deciding.
