The hard part of buying a cordless vacuum is not finding one that cleans well. Most of them do, at least when new. The hard part is finding one that still works in three years, because the failure rate in this category is genuinely poor and the usual pattern is a machine dying somewhere between twelve and twenty months, just outside its warranty.
So this guide weights longevity heavily. Four machines, ranked on what their owners report after a year rather than on headline suction figures, which in this category are close to meaningless.
Quick picksWe shortlist products sold in the UK, then analyse verified owner reviews for recurring praise, recurring faults and how products hold up over months of use. Unless a product is marked WHC Tested, we have not used it ourselves.
Read how we choose what to recommend →Why suction figures are the wrong thing to compare
Cordless vacuum listings advertise suction in pascals, and the numbers have inflated to the point of absurdity. You will see 35,000 Pa, 50,000 Pa, even 70,000 Pa on machines costing under a hundred pounds, while the best-regarded vacuum in this guide does not publish a pascal figure at all and one of the most trusted names in the category quotes a figure a fraction of those.
Pascals measure sealed suction at the nozzle with nothing attached. They say nothing about airflow, which is what actually carries debris up the tube, and nothing about whether the brush roll agitates carpet pile. A machine can post a huge pascal figure and still leave fluff on a rug. Treat the number as marketing and read what owners say about the specific surfaces you have.
- Weight, and where it sits. The range here is 2.25 kg to 5.5 kg, and that is before you account for whether the weight is in your hand or down at the floor. A heavy stick vacuum is tiring in a way a heavy upright is not, because you are holding it rather than pushing it.
- Runtime in the mode you will actually use. Headline figures are quoted in eco mode, often with the brush roll off. Expect to halve them for real cleaning, and read the honest numbers in each entry below.
- Whether the battery is replaceable. The battery is what fails first on almost every cordless. If it unclips and you can buy a new one, the machine has a second life. If it is sealed in, the machine is disposable.
- Guarantee length. Given that this category’s typical failure happens between one and two years, the difference between a one year and a five year guarantee is the difference between a repair and a replacement.
How the four compare
| Product | Owner rating | Weight | Real runtime | Bin | Guarantee |
|---|---|---|---|---|---|
| Gtech AirRAM MK2 | 4.6 from 10,627 | 3.2 kg | 40 min | 0.8 L | 2 years |
| Shark Stratos IZ420UKT | 4.3 from 1,363 | 5.5 kg | About 70 min across 2 batteries | 0.7 L | 5 years |
| VACTechPro P02 | 4.3 from 6,059 | 3.53 kg | 45 min eco, 18 max | – | Not stated |
| Akitas V8 | 4.2 from 26,302 | 2.25 kg | 40 min eco | 0.8 L | 2 years |
The one-star share is the column we cannot put in a table but which matters most. The Gtech sits at 3%, the Stratos and the Akitas at 8%, and the VACTechPro at 11%. Across ten thousand ratings, three per cent is a different kind of product from eleven.
Gtech AirRAM MK2
Best for: Buying onceThe one to buy if you want to stop buying vacuums. It does one job, does it very well, and its owners keep it for years. Pair it with a handheld for everything it cannot reach.
- You want the lowest chance of replacing it in two years
- Floors are what you want cleaned
- You find other cordless vacuums tiring on stairs
- You need attachments for upholstery or corners
- You want adjustable power
- Your sofas sit very low
- 4.6 stars from 10,627 owners, with only 3% one star, the best ratio in this guide by a wide margin
- Owners describe it in decades rather than months. Several are on their second after ten years with the first, and one writes that other brands last two years at best
- AirLOC picks up large debris on the forward stroke and locks on the backstroke to lift embedded dust, which is why it handles carpet and hard floor without a setting to change
- At 3.2 kg with a low-profile handle it goes flat under sofas and beds, and owners single out stairs as where it is easiest
- The bin empties with one flip of a latch, no dust cloud
- LED headlights across the front, and quiet at 70 dB. One owner replacing a twelve-year-old Henry describes it as far quieter
- Removable 22 V battery, and replacements are widely available from third parties
- No attachments at all. No crevice tool, no upholstery brush, nothing. It cleans floors and that is the whole proposition
- £188 is a lot for a machine with no tools, and owners who want to do stairs properly or reach a cobweb will need a second device
- The floor head is tall enough that it will not fit under some low sofas
- One speed only, with nothing to adjust
- The handle has a little flex where it joins, which owners mention as the price of its manoeuvrability
- 40 minutes and a four hour charge, so a large house means planning
- Owner rating
- 4.6 from 10,627
- Weight
- 3.2 kg
- Runtime
- 40 minutes
- Bin

- Guarantee

The reason this is first is not its rating, though 4.6 is the highest here. It is the shape of the reviews. In a category where the recurring story is a machine dying at eighteen months, this one has owners buying a replacement because they wore the first one out over a decade. That is a different kind of product, and three per cent one-star across ten thousand ratings is the number that proves it.
Be clear about what you are giving up, though. There are no tools in the box, not even a crevice nozzle, and at £188 that stings. Gtech’s answer is that the AirRAM cleans floors and the company sells a separate handheld for everything else. Whether that is focus or a gap depends on whether you already own something for the sofa.
Shark Stratos IZ420UKT Pet Pro
Best for: Deep pile carpetThe right choice if you have deep carpet and want one cordless to do everything. The guarantee is excellent and Clean Sense IQ genuinely works. Buy the single battery version unless your house is large.
- You have thick carpet that needs real agitation
- You want a full tool set and a long guarantee
- You would rather the machine chose its own power setting
- Weight is a concern for whoever will use it
- You believed the 120 minute figure
- You want the best value per pound
- A five year guarantee, two on the batteries, which is the longest cover in this guide and the right answer to this category's failure rate
- Clean Sense IQ senses dirt and raises suction on its own, and it is the feature owners praise most unprompted. One describes it ramping up audibly the moment it finds a patch
- DuoClean puts two brush rolls in one head, and an owner with a four-bed house that is 80% deep-pile carpet reports it matching their previous corded Shark
- Anti Hair Wrap Plus, with owners who have moulting pets reporting they have never had to cut hair off the roller
- Two removable batteries and a dual dock, so one charges while the other works
- A proper tool set including a motorised pet tool, which the Gtech above has none of
- Folds down for storage
- The 120 minute runtime is not realistic. Shark qualifies it to eco mode with a non-motorised tool, meaning the floor head off, and an owner who timed it over several days reports about 70 minutes across both batteries
- At 5.5 kg it is the heaviest here, and weight draws regular complaints including from a buyer whose 89-year-old mother could not manage it
- The anti-odour cartridge is the one feature owners say they cannot detect working
- One owner's motor failed at six months, with debris getting into the motor housing, followed by a warranty runaround between Shark and Amazon that left them without a vacuum for weeks
- By far the most expensive option here
- The 0.7 litre bin is the smallest in this guide
- Owner rating
- 4.3 from 1,363
- Weight
- 5.5 kg
- Runtime
- About 70 minutes across two batteries
- Bin
- 0.7 L
- Power
- 25.2 V, 181 W
- Guarantee
- 5 years, 2 years on batteries
- Tools
- Pet, crevice, multi-surface, anti-allergen brush
Clean Sense IQ is the feature worth the money. Owners describe hearing it ramp up the instant it hits a dirty patch and settle again afterwards, which means you are neither running on maximum and flattening the battery nor on eco and missing things. It is the rare piece of vacuum technology that owners mention without being prompted.
On runtime, be realistic. The box says 120 minutes; Shark’s own footnote says that is two batteries in eco mode with the brush roll not running, and the owner who actually timed it got about seventy with the head turning. Seventy minutes across two batteries is still generous, and one owner cleans a four-bedroom house with charge to spare on a single battery. It is just not two hours.
And weigh the weight. At 5.5 kg this is the heaviest thing here, and a stick vacuum’s weight is in your hand rather than on the floor. If it is for someone older or with a bad back, the Akitas or the Gtech will suit far better.
VACTechPro P02 Cordless
Best for: A capable vacuum under a hundred poundsA lot of vacuum for the money, with a real risk attached. Buy it as a second machine or for a flat, test the battery hard in the first fortnight, and do not expect it to be the one you still own in five years.
- Budget is the binding constraint
- You want a spare battery option at this price
- It is for a flat or an upstairs-only machine
- You want one machine for a whole house
- You want the lowest chance of a faulty unit
- You need an upholstery tool
- 4.3 stars from 6,059 owners at well under a hundred pounds, and currently the number two bestseller in its category with over 4,000 sold last month
- A detachable battery that charges on or off the unit, so a spare turns it into a whole-house machine
- A V-shaped roller designed to channel hair rather than wind it on, and owners with cats report fur going into the bin rather than round the brush
- A telescopic metal tube that latches at several lengths, including high enough for ceiling corners
- The green headlight, which owners consistently say shows up dust they would have walked past
- Converts to handheld for stairs and the car
- An owner recovering from a stroke, with one working arm, describes it as manageable where a corded machine was not
- Eleven per cent of its ratings are one star, the highest in this guide, and battery faults are the common thread, including units that will not charge at all
- Eighteen minutes on maximum is short, and owners describe it as a flat or small house machine rather than a whole-house one
- The plastic does not feel rigid, which more than one owner raises
- No powered upholstery tool, and the accessories that are available separately are expensive relative to the machine
- At 3.53 kg it is heavier than its lightweight billing suggests
- The listing is third-party sold, and this model has already been superseded by a newer one
- Owner rating
- 4.3 from 6,059
- Weight
- 3.53 kg
- Runtime
- 45 minutes eco, 18 minutes max
- Suction
- 35,000 Pa claimed
- Battery
- 2500 mAh, detachable
- Filter
- HEPA
- Tools
- Crevice and combi nozzle
The detachable battery is what makes this worth considering over everything else at the price. A spare costs a fraction of a better vacuum and doubles your runtime, and it means a battery failure is an inconvenience rather than the end of the machine. That matters more here than usual, because battery faults are exactly what its one-star reviews describe.
Eleven per cent one-star is the figure to hold in mind. It does not mean it will fail, and 72% of owners give it five, but it is three or four times the Gtech’s rate. Unbox it, run it flat, charge it fully and run it flat again inside the return window.
Akitas V8 3-in-1 Cordless
Best for: A light second machineHonest value at the price, as long as you buy it for what it is: a light machine for daily tidying alongside something stronger. Do not expect it to be your only vacuum.
- You want something light for a daily quick pass
- You already own a corded or upright machine
- Budget is the whole decision
- This would be your only vacuum
- You have thick carpet
- You need consistent suction rather than variable
- The lightest machine here at 2.25 kg, and weight is the single most praised thing about it across 1,300 mentions
- Far and away the cheapest option in this guide
- Detaches to a handheld with a crevice tool and dusting brush, and owners use it in the car
- Wall mount included, which matters in a small flat
- A 0.8 litre bin, the same as the Gtech costing nearly three times as much
- Owners replacing early Dyson cordless models consistently say this is lighter, quieter and lasts longer between charges
- A two year guarantee at this price
- The suction reports are not mixed so much as contradictory. Amazon's own summary notes that some owners praise brilliant suction while others report very poor suction, and some say it picks up everything while others say it picks up nothing
- Reliability draws 1,100 mentions, and battery failure after a couple of months is a recurring theme
- Owners are consistent that it will not lift larger debris and is not a replacement for a corded machine. One with three dogs and two rabbits uses it between proper cleans rather than instead of them
- Six hours to charge for forty minutes of use
- The 26,302 ratings cover the V8, V9 and V10A together rather than this model alone
- Third-party sold
- Owner rating
- 4.2 from 26,302 across the V8, V9 and V10A
- Weight
- 2.25 kg
- Runtime
- 40 minutes eco
- Bin
- 0.8 L
- Power
- 22.2 V, 150 W
- Charge
- 6 hours
- Guarantee
- 2 years
The suction split here is unusual enough to be worth explaining. When some owners say a vacuum picks up everything and others say it picks up nothing, you are usually looking at either variable manufacturing or two very different sets of expectations. In this case it is mostly the second: owners using it on hard floors and rugs for daily crumbs and fur are delighted, and owners expecting it to replace an upright on thick carpet are not. Buy it for the first job and it is excellent value.
One we will not recommend
The Ultenic cordless range appears high in Amazon’s listings and would have been an obvious mid-range pick. It is not here because Amazon itself flags it as a frequently returned item, with a note suggesting shoppers consider alternatives with lower return rates. When the retailer is warning people off a product, that is worth more than any specification, and we are not going to argue with it.
Which cordless vacuum should you buy?
For most people, the Gtech AirRAM MK2. It is the only machine here whose owners talk about it in years rather than months, its one-star rate is a third of everything else, and it is genuinely the easiest to use on stairs. Accept that it cleans floors and nothing else.
If you have deep carpet, or you want one machine with a full tool set, the Shark Stratos is the better cleaner and has a five year guarantee behind it. Buy the single-battery version, ignore the 120 minute figure, and think about the 5.5 kg before you order.
On a budget, the VACTechPro P02 is a lot of machine for under a hundred pounds with a swappable battery, as long as you test it properly in the first fortnight. And the Akitas V8 is the cheapest thing here that genuinely works, bought as a light second machine rather than your only one.
The pattern worth taking from all four: in this category you are buying a battery and a guarantee as much as a vacuum.

Cordless vacuum buying guide: your questions answered
Do the suction numbers on cordless vacuums mean anything?
Very little, as advertised. Pascals measure sealed suction with nothing attached to the nozzle, which tells you nothing about airflow, and airflow is what actually carries debris up the tube. It also tells you nothing about whether the brush roll agitates carpet pile, which is what lifts embedded dirt. You will see machines under a hundred pounds claiming 70,000 Pa while the best-regarded vacuum in this guide publishes no pascal figure at all. Read what owners say about your specific floors instead.
Will a cordless clean as well as my old corded vacuum?
On hard floors and short pile, comfortably, and the convenience means you clean more often which matters more than peak power. On deep pile carpet a good corded upright still has an edge, though the better cordless machines now get close: one owner of a four-bedroom house that is 80% deep-pile carpet reports their cordless matching the corded Shark it replaced. If your home is mostly thick carpet, buy at the stronger end rather than the budget end.
How long do cordless vacuums actually last?
Less long than they should, which is the real problem in this category. The common pattern is failure between twelve and twenty months, usually the battery, and usually just outside a one year guarantee. That is why guarantee length and whether the battery is user-replaceable matter more than any performance figure. One machine in this guide has owners on their second unit after ten years with the first, and that is the exception rather than the norm.
Should I buy one with a removable battery?
If you can, yes. The battery is what fails first on almost every cordless vacuum. If it unclips, a failure is a thirty pound part and the machine carries on; if it is sealed in, the machine is disposable. A removable battery also lets you buy a spare and swap mid-clean, which turns a forty minute machine into an eighty minute one. Check that replacements are actually sold before you buy, not just that the battery comes out.
How much runtime do I really need?
Less than you think, but more than the box says. Quoted figures are measured in eco mode and sometimes with the brush roll switched off, so halve them for real cleaning. Forty minutes of genuine runtime covers a two or three bedroom house comfortably. The thing that catches people out is maximum power: a machine quoting forty five minutes may give under twenty on its highest setting, so if you plan to clean on boost, read the maximum figure rather than the headline.
Is a lightweight cordless worth paying for?
It is the feature most likely to decide whether you use the thing. The range in this guide runs from 2.25 kg to 5.5 kg, and a stick vacuum’s weight is held in your hand rather than pushed along the floor, so the difference is felt far more than the numbers suggest. Weight is the most discussed topic in the reviews of several machines here, and in one case a buyer returned a well-reviewed vacuum simply because their elderly mother could not hold it up.
Why do cheap cordless vacuums have such mixed reviews?
Usually because two different buyers are reviewing two different jobs. A light budget machine used on hard floors for daily crumbs and fur earns five stars; the same machine bought to replace an upright on thick carpet earns one. Genuine manufacturing variance exists too, and it shows up as battery faults more than anything else. The practical approach is to read the one-star reviews specifically, see whether they describe a broken machine or a disappointed expectation, and judge accordingly.
Do I need attachments, or is a floor-only vacuum enough?
It depends entirely on whether you own anything else. A floor-only machine with no tools can be excellent at the job it does, and the best-rated vacuum in this guide has no attachments at all. But stairs, sofas, skirting boards and car interiors need something, so a toolless machine means buying a handheld as well. Work out the total cost of both before comparing it against an all-in-one, because sometimes the all-in-one is cheaper.
