Eufy E20 3-in-1 robot vacuum cleaner review: perhaps the only home cleaning system you'll ever need

Welcome to T3's review of the new Eufy E20, a 3-in-1 robot vacuum cleaner that transforms into a cordless stick and hand vacuum in a thrice.

To be honest, when I first clapped eyes on this weird-looking contraption in a CES forum I thought it was a ridiculous idea, despite it winning the CES Best of Innovation Award 2025. But I’ve changed my mind since having it in the home for the past few weeks, and can genuinely see the need for a model like this that can switch from robot vacuum to stick vacuum and then back again within seconds.

Despite its unusual looks, does this transformer of the robo vacuum world merit a lofty spot in our guide to the best robot vacuum cleaners or is it ultimately just another silly Heath Robinson-esque gimmick? Let’s get down to the nitty and the gritty.

Eufy E20 review: price and availability

As the Eufy E20 has only just been launched, your best UK port of call is the Eufy store where it’s selling for a not unreasonable £549. However, you can be sure that many other online stores will soon follow.

If you live in the USA, try the Eufy store or Best Buy, where it’s selling for $549.99. And if you're in Europe, head to your country's official Eufy online store.

Eufy E20 review: why would you need a transforming robot vacuum?

A 3-in-1 robot vacuum that morphs into a stick and hand vacuum isn’t as silly as it sounds. After all, every reviewer of any robot vacuum will always suggest having a cordless stick vacuum to hand in order to sweep the many areas that are inaccessible to robot vacuums – like along the very edge of carpeted skirting boards, under low cupboards, down the side of the sofa, the car, shelving, the list goes on. These are all areas that only a stick- or hand vacuum can reach so it makes perfect sense to provide a three-in-one solution for those who don’t own a cordless stick vacuum or even those that do but it’s always stored away on a different floor. You get the drift.

Take my admittedly fortuitous circumstances as an example. I have a Roborock Saros 10R cleaning downstairs which is mostly comprised of wooden floors. This bot both vacuums and mops the floors on a regular basis, keeping all the pet hair in my home at bay. Anything it misses can be cleaned using my Dreame cordless stick vacuum that’s stored in a back room on the same floor.

However, the Saros 10R is unable to climb my stairs to clean my almost totally carpeted upstairs rooms. Of course, I could take the Saros upstairs but what a rigmarole that would be, especially if done on a regular basis. And besides, it would spend ages trying to find its charging-cum-self-emptying dock which, of course, is downstairs.

So I’ve put the Eufy E20 upstairs where it’s been vacuuming three carpeted bedrooms and the hallway, along with a hard floor bathroom. This means I don’t have to periodically dash downstairs to get the stick vacuum because there’s one built into the robot upstairs (a first world problem, granted). I simply bend down, press the big red button, reach for the main floor head with suction tube attached and finish off all the areas missed by the bot.

That’s one admittedly ostentatious example for lazy, well-heeled home owners. But what about those many potential customers who can’t afford to have both items in the home, or those who simply want to keep clutter at bay and want a convenient all-in-one solution that actually works?

Well, having had the Eufy E20 running for the past few weeks and using its stick vacuum option on a regular basis, I can vouch that both the robot section and the stick-vacuum unit perform surprisingly well, and for arguably less than the combined price of a comparable robot vacuum and stick vacuum. And that makes it well worth consideration.

Eufy E20 review: robot design and features

Put simply, there’s nothing else like the Eufy E20 on the market right now and perhaps not surprisingly so because it takes a certain type of out-of-the-box thinking to even consider something as offbeat as a robot vacuum cleaner that can transform into a stick or hand vac.

I guess we should first address the elephant in the room. In terms of styling, the Eufy E20 robot wins no prizes for looks. In fact at first glance it resembles either a hotrod with the engine bonnet off or something out of George Miller’s Mad Max. Let’s just say that it’s not the prettiest of robot vacuums, not that it matters.

The E20 measures 34.5cm in diameter and 11.5cm in height to the top of its LiDAR turret. This is considerably taller than most other bots on the market – especially the new Roborock Saros 10R which is just 7.9cm in height. The reason for this extra height is almost certainly as a result of the robot accommodating the removable hand vacuum module. However, the E20 will still be capable of venturing under most furnishings including the majority of beds and sofas.

Although you’re advised to use the Eufy Clean app with this bot, it does come with some controls on the unit itself that provide instant access to robot controls like its four suction power bands, return to dock and 'start vacuuming'. However, the icons on these buttons are written in black-on-black so are impossible to read in anything other than bright lighting. Besides, the only time you might use them is if the robot’s stuck and you need to reinitiate it after untangling its roller or you want it to stop working and return to home.

Like so many robot vacuums these days, the E20 uses LiDAR for its navigation and that means it is quick to map an entire floor plan and very good at finding its way around the home without getting lost. It’s also equipped with dual laser sensors for real-time obstacle detection and 129° ultra-wide front scanning for edge cleaning. However, it doesn’t have a front mounted camera or headlight though it doesn’t seem to need them because at no time has it got lost when working in the dark.

The E20 sports 8,000 Pascals of suction power which is above average for a robot vacuum in this price band. However, the stick vacuum module produces a whopping 30,000Pa at full bore. You may wonder why this should be, given that the stick vacuum module’s motor provides all the power for the robot’s suction. I did too, until I realised that if the robot used 30,000 Pascals of suction power it would drain its battery very quickly – well before it had completed its vacuum tasks and possibly within about 15 minutes.

However, in my tests I’ve found that the combination of the bot’s existing suction power and its effective single bristle-and-rubber brush bar is more than a match for almost all household detritus. The E20 also features a spinning side brush for sweeping along edges and around table legs. However, since the side brush isn’t on an extendable arm like some premium Roborock and Dreame models, it won’t be able to reach into some corners. Incidentally, this model comes with four levels of power – Quiet, Standard, Turbo and Max – and also features BoostIQ, a dust detection function that automatically ramps up the suction when required.

I’m also pleased to say that this bot traverses even the loosest of thin rugs with ease without getting entangled in them. This is a major bonus because many robots don’t like rugs, especially if they’re not fixed down with anti-slip rug grippers.

Since the E20 uses the hand-vacuum module with both motor and bin onboard as its engine, it has an excellent filtration system comprising five advanced cyclone structures than can supposedly ‘capture up to 99.7% of particles as small as 0.3 microns, including bacteria, pollen, mites, hair and fleas’. I’ll take that, and so will you if you suffer from any dust-related allergies.

Eufy E20 review: stick design and features

Now here’s the clever part. When the robot isn’t vacuuming you can simply reach down, press a big red button and retrieve the built-in hand vacuum unit. To make those quick detailing tasks easier, there’s a nozzle for the hand vacuum built into a recess in the robot, plus it also ships with a separate rectangular detail brush that you will need to find a storage place for. However, the unit itself is made from the kind of smooth, shiny plastic that attracts dust like flies to a cowpat.

The third and final part of the system comprises an extendable suction tube that measures 47.5cm to 72cm in length and a full-sized Dyson-style brush head that measures 21.5cm across. This brush head has great articulation and is very easy to steer around furnishings. The combined weight of the hand unit with suction tube and main brush head is just 2.5kgs, and that’s pretty darn light in my book. The hand unit, meanwhile, produces an impressive 30,000 Pascals of suction power and offers the same four suction levels as when it’s in robot mode, which means decent versatility for all surfaces, from hard floor to deep-pile carpet.

One of the main disadvantages of this admittedly small and light stick vacuum is that its bin is just 0.3 litres and that’s about half the size of the competition. It’s not really of much consequence when it’s being used in robot mode but you will quickly fill the bin up in stick mode especially if, like me, you live with a menagerie of furry animals. To empty the contents you have two choices: unscrew the container cap and pour the contents into the kitchen bin or place it on the robot and let the dock empty it for you. However, auto empty in the dock only works after the hand vac has been used for at least 10 minutes, which is kind of weird.

Eufy E20 review: dock design and features

Where most current robot vacuums also mop the floor, this one only vacuums and I personally think it’s much better for it, mostly because I’m not a fan of robots that also mop. Why? Well firstly my hard floors only require occasional mopping and I really don’t mind doing the task myself. I would rather have a robot vacuum with a smaller automatic dustbin emptying dock and a much larger dust bag inside it. Which is exactly what this model has. In fact, at 3 litres, the Eufy dock’s dust bag holds about 300ml more than any Roborock I’ve tested. Eufy states up to 75 days of auto-emptying before the bag needs throwing away, but I think it would be nearer to around 40 days if you have several shedding pets in the home.

I should add that the dock is quite cheap looking and made from thin textured grey plastic with a not especially tactile lid to the dust bag. Nevertheless, it doesn’t stick out like a sore thumb because, at 38cm in height, 24cm in width and just 17cm in depth, it’s so much smaller in stature than any other robot dock on the market. Mind, it’s also light as a feather which means you may need to use double sided tape on the bottom if locating it a few inches away from a wall on hard floor or the bot will simply push it away, often at an angle. The included clear plastic base extension helps in this regard.

Eufy E20 review: robot vacuum performance

I’ve been pleasantly surprised by how well this robot vac has performed on both hard floor and carpet. It had no problems collecting oats and crushed biscuits on the kitchen hard floor though it did leave a few oat flakes behind when subjected to the same test on a medium-pile rug. However, at other times it’s been excellent at collecting Labrador hair on the same rug.

As a result, I would say its carpet performance is above average for a robot vac at this price level. And that’s a good thing. What isn’t so great is the noise it makes. In fact it’s one of the louder robot vacs I’ve tested. Not hideously loud by any means, but you might not want it running while you’re watching telly.

Heading to the roller brush, I have noticed that the rubber parts are easily sliced by pieces of stray cotton if they so happen to tighten around the bar. It doesn’t affect performance, but it would be handy if Eufy included a spare roller brush or perhaps redesigned it using tougher rubber.

Although the E20’s initial mapping run didn’t produce the most accurate map, it was relatively easy to divide and merge rooms in the app. Put another way, its mapping was below the standard set by Roborock’s latest fleet. However, I like the way it cleans in a methodical fashion of usually doing the edges first before tackling the rest in linear fashion.

Regarding its obstacle avoidance, I’d say that the E20 is among the very best of any model I’ve tested, even some premium models. In fact, along with the Roborock Saros 10R, it has been the only robot vacuum capable of avoiding a thin bone that has caught out every other bot I’ve tested.

However, like almost all LiDAR-equipped robot vacuums bar the Roborock Saros 10R, the E20 treats fabric valances on sofas and beds as a solid barrier so you will need to lift any valances if you want it to clean beneath.

Although not really a disadvantage, the robot unit has occasionally docked at a slightly skew angle but I put that down to the lightness of the charging dock which can move around quite easily.

Eufy E20 review: stick vac performance

The E20 easily converts to a stick vacuum, and with its combination of 30,000 Pascals of suction power and a very well designed floor head, it’s a mini force to be reckoned with. Hence it sailed through all my carpet and hard floor tests with aplomb. I’d say it’s up there with most well-regarded stick vacs on the market. And that’s not a bad accolade given that most of the time it serves as the engine to the robot vacuum unit.

However, the stick vacuum section is very loud when in use. In Quiet mode at ear level it measured 83dB and 86dB in Max mode. Thankfully you will rarely require that kind of power unless cleaning hard to reach areas like around car seats.

Eufy states a running time of 180 minutes in Quiet mode but I used it mostly in Turbo mode which reduced its running time to around 40 minutes – and that's still very decent. According to Eufy, it recharges in 2.5 hours which is better than a lot of the competition.

Eufy E20 review: dock performance

Most of the robot vacuums I’ve tested have occasionally clogged up the suction inlet to the base station’s dust bag when their internal bins have been too full of compacted pet hair. But that’s hardly surprising given I live in the dusty countryside with two dogs and three cats.

However, unlike other robot vacs, this model’s bin is in the hand-vac section and the debris inside is loosened by spinning like a cyclone whenever the bin is being emptied into the dock. In fact you can watch it in motion through the bin’s semi-transparent casing. Consequently I have not had one moment in two weeks of use where the dock’s suction tube has been blocked by too much detritus. This element has really impressed me because I’ve even experienced blockage issues with some very high-end models.

You get two auto-empty settings in the app – Standard and Deep Dust Collection – but even the standard setting is usually sufficient enough to empty the robot’s bin. However, if you set it to Deep Dust Collection, it goes through a repeat suction process where it switches from the sound of a jet at take off to a more subdued whirr before switching to a different tone that’s higher in pitch. And it does this about three times. The downside is that the process is very, very loud in this mode but the upside is that nothing can escape its unbridled power. In fact you can hear a woomph sound as all carpet matter, gravel pieces and pet hair is sucked into the dock’s substantially large three-litre dust bag .

Eufy E20 review: Eufy Clean app

The Eufy Clean app is pretty easy to navigate but it’s not as accomplished as Roborock’s. You get all the usual stuff like map editing, multi-floor mapping, schedule settings and a fair tranche of customisable options like carpet settings and how often you want the robot to empty its bin.

However, there is no ability to save a created zone and add it to a weekly schedule. For instance, with my Roborock I can go to schedules and create a specific zone I want cleaned – the rug in front of the dogs’ bed – on a regular basis. I’m hopeful that Eufy will add this function in a future firmware update. Otherwise, this app is not too shabby at all.

Eufy E20 review: verdict

Against all odds, the Eufy E20 3-in-1 has turned out to be much better than I expected. It’s not gimmicky at all but a product that performs well in all three disciplines, whether it’s vacuuming the floors on its own or serving as a very competent stick and hand vac. Small wonder it won that CES award for innovation.
