Best Vacuum Cleaners 2026: 10 Cordless Ranked, and Why 55kPa Is Half a Vacuum

Eight hundred and eighty-seven ratings at 4.7 stars is the best combination of depth and average in this comparison, and the hardware justifies it. The U18 Pro is the best cordless vacuum cleaner here for a normal house because of three things that are genuinely measurable: a 1.6 litre dust cup, more than double what any Shark on this page holds; a self-standing design that stays upright when you let go, which sounds trivial until you have propped a stick vacuum against a wall for the fiftieth time; and a folding wand with what Ultenic calls a 3/7 joint, which bends closer to the head than the usual halfway hinge and therefore reaches further under a sofa without you crouching. It is also the only generic on this page that publishes a battery voltage — 36 volts DC — rather than leaving you with a wattage and no way to check it. The multi-cyclonic separation keeps the HEPA filter cleaner for longer, which is the mechanism that actually preserves suction over months, and the V-shaped anti-tangle roller with anti-static filaments addresses the failure mode that kills these machines in houses with long hair. Sixty-two decibels is quiet for the class. The headline numbers deserve the usual scepticism. Fifty-five kilopascals is 54% of a perfect vacuum, and the 600 watt motor rating sits against a battery that, on the arithmetic the Powerffy listing at number three makes possible, can sustain roughly 250 watts at best. The 80 minute runtime is an eco-mode figure and Ultenic does not publish the maximum-mode equivalent, which is the one omission that keeps this from being the honest listing as well as the best-liked one.

Two hundred watts. That is the first number in the first bullet of this listing, from the company whose name became the British verb for vacuuming and which has been making these since 1908. Every generic on this page claims 600 or 650 watts at a similar or lower price. The Powerffy listing at number three lets you check who is right: it publishes an 8-cell 2500mAh battery, which is 72 watt-hours, and a maximum-mode runtime of 17 minutes, which works out at 254 watts of actual draw. Two hundred watts is the same order of magnitude as physics allows. Six hundred is not. For £99 the specification is honest and sufficient. Three genuine speed modes — eco, standard and turbo — a detachable battery you can charge on or off the machine, a 50 minute runtime, an anti-hair-wrap nozzle, LED headlights, double-edge cleaning that reaches along skirting boards, and a park-anywhere upright stand. The 0.7 litre bin is the standard brand-name size and small next to the generics. Four point one stars from 542 ratings is the lowest average in this comparison and it is the honest reason this is second rather than first. Hoover has had a difficult decade in cordless, and the critical reviews cluster on build plastics and battery life over time rather than on suction. Buy it because the numbers on the page are real and the brand is serviceable in Britain; do not buy it expecting Shark's construction.

This is the most useful listing on the page and it did not mean to be. Powerffy publishes what everyone else hides: "three manual modes (18/28/50KPa)" and "up to 65 mins in Eco mode (35 mins in Mid, 17 mins in Max)". Line those up and the marketing collapses honestly. The 50 kilopascals in the title is the Max figure and it lasts seventeen minutes. The 65 minutes in the title is the Eco figure and it happens at 18 kilopascals. Neither is a lie; together in a title they describe a machine that does not exist. It goes further and publishes the battery: "high-density 8-cell 2500mAh system". Eight cells in series at 3.6 volts is 28.8 volts, and 28.8 volts times 2.5 amp-hours is 72 watt-hours. Seventy-two watt-hours over seventeen minutes is 254 watts of real draw at maximum, against the 600 watts advertised. Every other generic on this page has the same class of battery and the same physics; this is simply the one that gave you the numbers to work it out. As a product at £99.99 it is well judged: a 1.5 litre bin, an internal ring scraper that strips hair off the filter at the press of a button rather than by hand, a one-metre hose for cars and ceilings, self-standing, and 62 decibels. Two hundred and fifty-six ratings at 4.5 stars is a mid-sized but healthy sample. The specification field, less impressively, opens with the company's support email address.

"Enjoy up to 60 minutes run-time* and charge the removable battery on or off the vacuum (*In ECO power mode, with non-motorised tool)." That footnote is the most honest sentence collected across this entire category. Every generic on this page publishes a runtime; this is the only listing that tells you both the power mode and the attachment it was measured with, which are the two variables that change the answer most. Shark publishes no kilopascal figure and no wattage anywhere, which in a search full of 55 kPa claims reads as a company declining to join in. What £249 buys instead is engineering you can see. Anti Hair Wrap Plus actively strips hair off the brush-roll while you clean rather than asking you to cut it off with scissors, which is the single biggest long-term failure mode in a house with pets or long hair. Clean Sense IQ senses dirt and raises power automatically, so the machine spends most of its life in a lower mode and the battery lasts. The DuoClean floorhead runs two motorised brush-rolls at once for carpet and hard floor together. Five-year guarantee, two years on the battery. Two real caveats. At £249 it is two and a half times the Hoover, and the 0.7 litre dust cup is the smallest class on this page — a third of what the £99.99 Powerffy holds, so you will empty it three times where the generic empties once. Four point three stars from 722 ratings is solid rather than outstanding for the money.

Eight hundred and twenty-four ratings at 4.7 stars is the joint-best average here on the second deepest sample, and the second bullet does something rare: "70 minutes of battery life at its lowest power setting, perfect for everyday whole-house cleaning (high suction mode: 25 minutes)". Both ends of the range, in one sentence, with the conditions named. Combined with the published 8x2500mAh battery — 72 watt-hours — that gives a genuine maximum draw of about 173 watts, and it makes this one of only three listings on the page you can actually audit. The hardware is generous for £119.99: a 1.8 litre dust cup, the joint largest here and two and a half times any Shark; an eight-layer filtration system down to 0.3 microns; a V-shaped anti-tangle roller; an OLED touchscreen; a telescopic tube; and a genuinely useful "Hurricane" boost mode for one-off heavy patches. Sixty-two decibels. The listing cannot agree with itself on the two numbers it leads with. The title says 600W and 50kPa. The first bullet says 600W and 50kPa. The Special Feature field says "Upgraded 650W Motor" and "55kPa Cyclone Suction Power". Four figures for two specifications, on one page, and no indication which describes the machine in the box. Given that both pairs are inflated against the 173 watts the battery supports, the discrepancy matters less than the habit it reveals — but a buyer filtering on wattage is being shown two different products.

Two features here are worth the premium over a generic and neither is a number. FloorDetect senses whether it is on carpet or hard floor and adjusts power without being told, which matters because the single biggest waste of battery in a cordless vacuum is running carpet power across a kitchen. Reveal Technology throws a low-angle light across the floor that shows up fine dust and dried pet accidents you would otherwise walk past — it sounds like a gimmick and it is the feature owners mention most. Six hundred and eighty-nine ratings at 4.5 stars is a strong sample, Flexology bends the wand to reach under furniture and folds it for storage, and the five-year guarantee is the longest on this page along with the other Sharks. The pet accessory set is included rather than sold separately. As with every Shark here, no suction figure and no wattage are published anywhere, which is a deliberate absence rather than an oversight. The special features field mentions a 50-minute runtime without stating the mode, which is less complete than the Stratos above it. And the 0.7 litre dust cup is the recurring brand-name limitation: at £189.99 you are getting a bin under half the size of a £99.99 Powerffy's. For a flat that is irrelevant; for a four-bedroom house with a dog it means two trips to the bin per clean.

Eight hundred and eighteen ratings at 4.4 stars is the third deepest sample here, and the specification is strong for £109.99. Four modes rather than the usual three, including an AUTO setting that raises suction when the head crosses onto carpet, which is the same idea as Shark's FloorDetect at £80 less. A 1.8 litre dust cup, joint largest on this page. A wall-mounted dock that charges the machine without plugging anything in. And a green LED in the floorhead rather than white, which genuinely shows up dust better against a dark floor because of how the light rakes across it. The support offer is unusually generous: a three-year protection plan, 30-day returns and 24/7 contact, from a brand with no UK history. Sixty-eight decibels is the loudest machine in this comparison by six decibels, which on a logarithmic scale is a noticeable difference. Two things pull it down. The 650 watt motor and 55 kilopascal suction are the standard inflated pair, and unlike FDUXUD or Powerffy this listing publishes only the eco runtime — "up to 70 minutes in energy-saving ECO mode" — with no maximum-mode figure to check it against. And the Special Feature field, which exists to hold technical specifications, contains: "★A Great Gift for Christmas★Mother's Day★Father's Day★Birthday★Thanksgiving Day". Thanksgiving is not a British holiday, and none of those are features.

One hundred and nine pounds ninety-nine is the cheapest route to a Shark with a five-year guarantee, and the final bullet contains something no other listing on this page manages: "Dimensions: H: 114cm, W:25cm, L:26cm, Weight: 3.2kg". Height, width, length and mass, all four, in one sentence. Nine other listings leave you guessing whether the thing fits in your cupboard. It is a simpler machine than the Stratos and honest about it. Two speeds rather than four, washable filters rather than HEPA, a hands-free dust cup that empties at the touch of a button without you putting a hand near it, and a charging dock included. Shark's pitch is anti-clog reliability rather than features, and for a small flat or a second machine for upstairs that is a reasonable proposition at this money. Three limitations. Three point two kilograms is the heaviest machine in this comparison, which for a stick vacuum you hold at arm's length to do stairs is the wrong end of the scale — the Ultenic and the generics sit closer to 3. The 0.69 litre dust cup is the smallest here outright. And 342 ratings at 4.3 stars is the thinnest sample of the three Sharks. Like its siblings it publishes no suction figure and no wattage, which remains the right call editorially even though it leaves nothing to compare.

Two published numbers make this listing worth reading. The first is noise: 58 decibels is the quietest in this comparison by four, and on a logarithmic scale that is a real difference in a flat. The second is the battery: "a 6*4200mAh removable battery", which is six cells at 4.2 amp-hours. Six cells in series at 3.6 volts is 21.6 volts, and 21.6 times 4.2 is 90.7 watt-hours — the largest energy store on this page. It also publishes both runtimes: "up to 80 mins of fade-free runtime (30 mins in Max mode)". Divide 90.7 watt-hours by half an hour and the maximum real draw is 181 watts; divide by 80 minutes and eco mode is 68 watts. The listing advertises 650 watts, which is 3.6 times what its own published battery can sustain. As with the Powerffy, the arithmetic is only possible because the seller was generous with the specification. For the money the rest is good: a 1.8 litre dust cup, an auto mode that detects floor type, a one-metre hose for cars and ceilings, eight-layer filtration and a 3 kilogram body with full dimensions published. What holds it back is evidence and price. One hundred and twenty-three ratings is the thinnest sample here, a 4.9 average on that few is not yet settled, and £169.99 is £70 more than the Powerffy and £30 more than the far better-evidenced Ultenic for no advantage the numbers can demonstrate.
