TechRadar Verdict

The Eufy HomeVac S11 Infinity is a cordless stick vacuum that comes with a range of attachments, making it a versatile cleaner that can tackle more than just your floors. It can be used as a handheld cleaner, too, for removing dirt and debris all around the home. A second battery allows you to always have a backup, ready to go. Dirt pick-up isn’t quite up to the level of the best performing cordless vacuums, but at around half the price it’s good enough.

One-minute review

Eufy by Anker is well known for making some of the best smart home security devices on the market, such as video doorbells and security cameras. However, the company is also now making waves in the floorcare world, with its range of robot vacuums and cordless vacuum cleaners that includes small handheld models as well as stick vacuum cleaners.

The Eufy HomeVac S11 Infinity is the brand’s top-of-the-range cordless stick vacuum, showing real potential to contend with some of the best cordless vacuum cleaners However, it comes with a price tag that’s affordable in comparison to many other cordless models on the market. As well as tackling floors, it can be used as a handheld vacuum for cleaning your car or for clearing cobwebs up-high, for instance. It comes with a useful range of attachments including a mini motorized tool, crevice nozzle, 2-in-1 combination tool and a flexible hose to help reach into awkward areas.

A big bonus with this vacuum is that it comes with two swappable batteries, so the second unit can always be on charge and ready to use. This minimizes the risk that you’ll run out of power, so the vacuum will always be ready to tackle sudden spills and mess.

On test it demonstrated good dirt collection, but it isn’t as powerful as some of the best cordless vacuums available. Nevertheless, the selection of attachments makes it a good all-rounder for cleaning every surface in your home. It’s ideal for surface dust and dirt, but busy homes with children and pets might find they’re using the max suction mode all the time to get a deep enough clean – which, with even two batteries, would deliver only 16 minutes of vacuuming time.

Eufy HomeVac S11 Infinity price and availability

  • List price: $299.99 / £229.99

You can buy the Eufy HomeVac S11 Infinity directly through Eufy in the US and the UK, but it isn’t available in Australia. If you’re happy to forego the second battery and the soft brush roller (for delicate hard floors), then it’s worth looking at the Eufy HomeVac S11 Go, which you can pick up for £179.99 / $249.99.

Eufy HomeVac S11 Infinity: design

  • Useful range of cleaning tools
  • Washable filters
  • LED lights on floorhead

The HomeVac S11 Infinity is similar in size to most other vacuums of this type – with the main floorhead attached, it measures 43.3 x 10 x 9.4 inches/ 110 x 25.5 x 24cm (h x w x d). The handheld unit without any attachments weighs just 3.75 lb/1.7kg.

It’s pretty intuitive to set up and use. All the parts and accessories fit together with a satisfying click and stay locked together until released using the button. The dust bin offers a decent 0.65-liter capacity, and is emptied directly into the trash simply by pushing the release button.

The main floorhead is fitted with a carbon fiber roller brush, but it’s also supplied with a soft roller brush that’s more suitable for delicate hard floors. And in addition to the main floorhead, there’s a mini motorized tool that’s ideal for deep-cleaning mattresses and upholstery, as well as awkward spaces such as stairs.

A crevice nozzle, 2-in-1 brush tool and a flexible extension hose make this a versatile vacuum for handheld as well as overhead cleaning. And virtually all the accessories apart from the flexible extension hose and spare floor roller brush can be stored on the wall mount, should you choose to install it.

The vacuum is operated by a trigger switch on the handle, which has to be held in continuously during operation. It always defaults to the mid-suction level, but a button on the top of the handheld unit allows you to switch between the three power levels.

Other than emptying out the dust, maintenance is pretty simple. The filters and roller brushes are all washable, so there are no expensive replacements to add to your shopping list.

Eufy HomeVac S11 Infinity: performance

  • Attachments click together with ease
  • Good suction on max mode
  • Can be messy to empty

In general, the Eufy HomeVac S11 Infinity’s dust and debris collection proved decent, and, as you’d expect, it’s most effective when on max suction – we were impressed by the amount of dirt it removed from our carpets on this high suction setting. But for general everyday dust, or for hard floors, the standard mode is sufficient. The headlights effectively illuminated dark corners, resulting in a more thorough clean.

When vacuuming up oats from hard floors, we noticed that while the Infinity was efficient at collecting the debris on the forward push, as we pulled it backwards, some oats were pulled backwards behind the floorhead instead of being sucked up. And at the edges of the room, when collecting oats right next to the baseboards, the cleaner was most effective when used head on, with the floorhead pushed up to the baseboard; the sides of the floorhead were less effective at collecting debris.

As an upright cordless vacuum, the Infinity is lightweight and easy to maneuver around corners, whether on carpet or hard floor. On a thick-pile area rug, the floorhead wobbled around significantly, and didn’t feel as sturdy as we’d have liked. Even on max suction, the vacuum didn’t manage to remove all of the debris from deeper within the fibers of the rug.

The trigger switch can become uncomfortable to hold if vacuuming for longer periods, but for a quick whizz around one or two rooms, it’s fine. We’d have preferred if the button to adjust the power level was closer to the trigger, so you could press it with the same hand that’s holding the vacuum. Nevertheless, this isn’t a big issue.

When used as a handheld vacuum, the Eufy HomeVac S11 Infinity makes light work of vacuuming stairs. In addition, the range of attachments makes it suitable for almost any job, including car cleaning, where the flexible hose proved handy for reaching awkward areas. This isn’t the most compact handheld vacuum, so it can feel a bit cumbersome in tight spaces, however.

The point-and-shoot style of dirt disposal means opening the dust canister to empty it is simple enough; but the dust and fluff didn’t always fall straight into the trash. A couple of times, we had to coax it out by hand, making it a messier job. Removing the filters was simple, though, and we like that they’re washable. The roller brushes are also washable, and while we noticed that hair became wrapped around them quite quickly, it was easily removed.

When vacuuming on max suction on hard floors, the Eufy HomeVac S11 Infinity hit 80dB on our noise meter, reducing to 74dB on standard suction mode. On carpet it was a slightly quieter 76dB on max mode, dropping down to 66dB on standard.

Eufy HomeVac S11 Infinity: battery life

  • Two swappable batteries
  • Up to 40 minutes' run-time per battery
  • 3.5-hour charge per battery

Eufy claims the battery will last for 8 minutes in max mode, 25 minutes in standard mode or 40 minutes when on the lowest power mode. We tested the Eufy HomeVac S11 Infinity on max power and the battery lasted for exactly eight minutes. The great advantage of having a second battery is that you can always keep one fully charged, so there should rarely be a situation where you run out of power completely.

The Infinity’s charging cable plugs directly into the battery, so it can be removed and charged wherever is most convenient. Or it can be charged while still in the cleaner, either in the wall-mounted dock or in your preferred storage spot. During testing, the battery took just under 3 hours to recharge, which is faster than advertised by Eufy.

Should I buy the Eufy HomeVac S11 Infinity?

Buy it if...

You want a cordless vacuum that won’t run out of juice

Running out of battery part way through cleaning a room is annoying to say the least, but with two swappable batteries, that shouldn’t be a problem with this vacuum.

You have delicate hard floors

For hard floors that require a gentler touch, the HomeVac S11 Infinity comes with a soft roller brush for the main floorhead. If you have carpet to tackle, too, you’ll find that switching the brushes is quick and easy.

You’re on a budget

This model is easily half the price of some of the leading cordless vacuum brands, yet you still get a good selection of accessories as well as two batteries and decent suction.

Don't buy it if..

You like an on/off switch

This vacuum has a trigger switch on the handle that has to be held in continuously while cleaning. If you don’t like having to hold in the trigger, look for a model with a simple on/off button.

You want the most powerful suction

The HomeVac S11 Infinity offers good dirt pick-up but it isn’t as powerful as some of the best cordless vacuums. So if your busy household needs a vacuum with super-strong suction for a deeper clean, this probably isn’t the cleaner for you.

You just want a vacuum for floors

A good selection of tools and accessories are only useful if you actually need them; otherwise, they’re just more things to store. So if you only want to vacuum floors then you may prefer a vacuum with fewer attachments.
