E20 3-in-1
2 independent reviewsRead the findings →A eufy robot vacuum whose motor lifts out to become a stick or handheld vacuum. It's a neat two-in-one for homes with mostly hard floors. It's weak on fine dirt in carpet, though, and it doesn't mop.

Feedback
What reviewers found
Two tests. RTINGS put the robot through its lab, and Vacuum Wars measured it as both a robot and a stick vacuum. Both found it very good on hard floors and with surface hair. They split on carpet and obstacles. Vacuum Wars got an above-average deep-carpet result where RTINGS found a lot of fine dirt left behind, and RTINGS rated its avoidance good while Vacuum Wars saw it dodge only 9 of 24 objects.
RTINGS, lab test, Apr 2025 · Vacuum Wars, lab test, Sept 2026
Hard floors
Reviewers rate it highlyRTINGS found it cleared debris of every size from bare floors, including along walls and in corners. Vacuum Wars also found it picked up every type and size of debris it tested.
Carpet and rugs
Mixed resultsVacuum Wars and RTINGS got different carpet results in robot mode. Vacuum Wars also measured stronger embedded-debris removal in stick mode, but a good result with the stick in your hand doesn't mean scheduled robot cleans will pick up as much.
Pet hair
Mixed resultsVacuum Wars found it picked up nearly all flattened pet hair with none tangled on the brush. RTINGS found deeply embedded pet hair left in carpet, though surface hair came up well.
Navigation and obstacles
Mixed resultsRTINGS found its lasers got it close to obstacles without touching them, and it rarely got stuck. Vacuum Wars saw it avoid well under half of the objects on its course, far below average. Pick things up before a scheduled clean.
Dock and upkeep
Not enough evidenceOnly Vacuum Wars judged the dock, finding it empties the small shared bin after both robot and stick use, but offers nowhere to store the stick parts.
App and software
Not enough evidenceNone of the reviews we use judged the app.
Noise
Not enough evidenceNone of the reviews we use judged how loud the robot or its dock is.
Reliability and support
Not enough evidenceNone of the reviews we use has run it long-term or judged eufy's support.
Value
Not enough evidenceNone of the reviews we use judged its value, though Vacuum Wars found the stick mode a properly capable cordless rather than a token extra.
Verdicts come from independent, hands-on, finished reviews. An area needs at least two of them before we say more than “Not enough evidence”. We don't score robots ourselves. How this works
Excellent on hard floors
RTINGS found it cleared debris of every size from bare floors, including along walls and in corners, and covered the room thoroughly. Vacuum Wars also found it picked up all types and sizes of debris, and its navigation covered ground slightly faster than average. For kitchens, hallways and wooden floors, the robot does its job well.
Carpet results disagree
RTINGS found it left a lot of fine material and deeply embedded pet hair in carpet, and it sometimes got bogged down and missed patches. Vacuum Wars recorded an above-average 81% in its deep-carpet test and picked up 97% of flattened pet hair, with none tangled on the brush. The two tests use different carpets and debris. Expect decent upkeep on rugs, but keep the stick for a proper carpet clean.
Obstacle avoidance splits the testers
RTINGS rated its lasers good at getting close to obstacles without touching them, and it rarely got stuck. On Vacuum Wars' course it avoided only 9 of 24 objects, well below the average of 16. With results that far apart, pick up cables, socks and pet toys before a scheduled clean.
A genuinely good cordless
As a stick, Vacuum Wars measured sealed suction well above average, pulled 97% of embedded debris from carpet and scored full marks on crevices. The handle weighs about the same as a Dyson Digital Slim. Airflow and runtime were a little below average, it pushed larger debris along hard floors, and it failed the fog filtration check. For quick jobs round the house, it's much more than a token handheld.
Awkward to convert and store
Vacuum Wars found the floorhead won't attach directly to the handheld, so stairs mean using the wand, and the tools don't fit the end of the wand. There's nowhere on the dock to keep the stick parts either. The robot and the stick share a small bin, though the dock empties it after each mode. Plan where the stick and its tools will live.
Both tests cover the E20 3-in-1. RTINGS tested it as a robot; Vacuum Wars tested both the robot and the stick.
Our take
Should you buy the E20 3-in-1?
Best for: Homes wanting one cleaner for floors, stairs and shelves. Skip it if: You need a thorough clean of thick carpets or stubborn stains.
Consider the E20 if you want scheduled vacuuming and a detachable vacuum in one machine, mainly for hard floors. Check the attachments first: the floorhead cannot connect directly to the handheld unit, and the small tools cannot fit on the wand. It does not mop, and the robot and stick modes have different cleaning and filtration results.
The E20 is eufy's odd one out. It's a laser-mapping robot vacuum with an emptying dock, but the battery, motor and filter lift out of the robot and click into a wand or a handheld body. So one machine covers the floors on a schedule, then does the stairs, the car and the cobwebs. The dock empties whichever mode you've used. There's no mop, which sets it apart from eufy's Omni robots.
The trade-off is that the robot part is average on carpet. It's great on hard floors and with loose hair, but testers found it leaves fine dirt in carpet pile and doesn't always avoid small objects. It's also 11.85cm tall, so it won't get under many sofas. The stick parts don't all fit together as neatly as a dedicated cordless, and there's nowhere on the dock to keep them.
Before you buy
The questions people ask about this one
Will it avoid cables and pet mess?
Don't rely on it. RTINGS found its lasers kept it clear of obstacles and pet waste in its tests, but Vacuum Wars saw it avoid only 9 of 24 objects. Pick things up before it runs.
Does it fit under low furniture?
Often not. The robot is 11.85cm tall, per the specifications, and RTINGS notes it can't clean under low furniture that shorter robots reach. The stick mode covers those gaps instead.
Can it cross rugs and raised thresholds between rooms?
eufy doesn't list a climbing height, per the specifications. RTINGS found it got bogged down on carpet and occasionally struggled to move, so it missed some patches. Thick or shaggy rugs are best left to the stick.
How often do I have to empty it?
Rarely. The dock empties the robot and the stick into a bag that eufy says lasts up to 75 days, per the specifications. Vacuum Wars found the bin the robot and stick share is small, so the dock does a lot of the work. There's no water to refill.
Is the stick mode any good?
Vacuum Wars measured strong carpet and crevice cleaning, with slightly below-average runtime. Filtration was weaker, and it failed the reviewer's fog test. The floorhead won't attach directly to the handheld unit and the small tools won't fit the wand, so think about the jobs you'd actually use it for.
Alternatives
Other robot vacuums to compare.
Omni C20
Why consider it: RTINGS found strong pickup on bare floors and near walls, and it adds mopping with a washing dock.
The compromise: It has no small-object avoidance, and testers disagree about its mopping.
RV30 Max Plus
Why consider it: Two home tests liked its fast mapping, easy app and compact emptying dock.
The compromise: Fine grit and sticky spills beat it, and the mop is only a light wipe.
Q7 M5 / M5+
Why consider it: RTINGS found dependable pickup on hard floors and effective pet-hair removal from carpet.
The compromise: Check whether an offer is for the Q7 M5 or the M5+ bundle, because pad washing and bin emptying depend on which one you get.
