Deebot X12S OmniCyclone
3 independent reviewsRead the findings →Ecovacs's refreshed bagless flagship, with a long roller mop that rinses as it goes. It's excellent at mopping messy hard floors and handles long hair without tangles. It only gets over low thresholds and can need help mapping around mirrors.

What reviewers found
Three home tests so far: BGR in a house with a toddler and a baby, CyberShack over a couple of weeks in Australia, and home&smart in Germany. All three rate the cleaning highly, especially the mopping and hair handling. BGR and CyberShack both had to fix the first map by hand because of mirrors. home&smart singled out the low climbing limit as its main weakness.

Hard floors
Reviewers rate it highlyBGR found it picked up debris of different sizes with little left on hard floors, and CyberShack reported minimal dust left behind.
Carpet and rugs
Reviewers rate it highlyBGR saw little debris left on carpet, and CyberShack found minimal dust left on either floor type, though it needed a vacuum-only run first to learn where the rugs were.
Pet hair
Reviewers rate it highlyhome&smart ran it daily for a week with long human hair and added pet hair, and the brush stayed spotless. BGR named pet-hair pickup as one of the main reasons to buy it.
Mopping
Reviewers rate it highlyCyberShack found it picked up stains other robots miss, and BGR called it excellent on everyday messes, though some really stuck-on stains stayed even with the pre-spray. home&smart liked the roller reaching past the body for edges.
Navigation and obstacles
Mixed resultsCyberShack found it approached furniture carefully and steered round cables once the map was fixed. BGR spent a while correcting a map confused by mirrors, and home&smart found it only climbs doorway thresholds of about 2.4cm.
Dock and upkeep
Mixed resultsCyberShack found the bagless bin easy to empty but said dust can escape, so it's best done outdoors. BGR liked not buying bags but found the app poor at warning when the bin is full.
App and software
Mixed resultsCyberShack found the app responsive and easy to use. BGR felt it advertised other products too often and was poor at flagging a full bin.
Noise
Not enough evidenceOnly CyberShack judged noise, finding it quiet enough on strong suction to keep watching TV without subtitles.
Reliability and support
Not enough evidenceNone of the reviews we use has run it long-term or judged Ecovacs's support, and the home tests lasted a couple of weeks at most.
Value
Mixed resultsCyberShack thought its results justify the premium price. BGR called it worth buying for heavy mopping and pet hair, but felt many people won't find the upgrade worth paying over the cheaper X12 OmniCyclone.
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
The roller mop is the highlight
CyberShack found it picked up stains other robots miss, and BGR called it excellent at mopping everyday messes. BGR did find some really stuck-on stains left behind, even with the pre-spray. home&smart liked that the roller extends past the body for edges and is washed in hot water after each run. For a kitchen or hallway that gets grubby daily, this is the reason to buy it.
Strong vacuuming, no hair tangles
BGR saw little debris left on hard floors or carpet, and CyberShack reported minimal dust left behind on either. home&smart ran it daily for a week in a home with shoulder-length hair plus added pet hair, and the brush was still spotless afterwards. If you're tired of cutting hair off brushes, this is a strong reason to shortlist it.
Mapping needs a helping hand
BGR spent a good while editing the first map, because the robot struggled with mirrors and merged rooms, and felt other brands map better. CyberShack also had to correct the map for floor-length mirrors, but after that found it approached walls and furniture carefully and steered round cables and loose objects. Plan to spend some time on the map at the start, especially if you have large mirrors.
Low doorway thresholds only
home&smart found it only gets over thresholds up to about 2.4cm, like its predecessor, and called it ideal for large homes without thresholds. Ecovacs claims up to 5cm for two-step obstacles, but none of the three testers reported measuring that. If there are raised doorway thresholds between your rooms, measure them before buying.
Bagless dock, with a dusty catch
CyberShack found the bagless bin easy to empty but said dust can escape, and suggested doing it outdoors. BGR liked not buying bags but found the app poor at telling you when the bin is full. BGR also felt the app advertised other products a little too often, while CyberShack found it responsive and easy to use.

Our take
Should you buy the Deebot X12S OmniCyclone?
Best for: Homes with hard floors where long hair tangles the brush. Skip it if: Your floors are cluttered or separated by raised thresholds.
buy it if you have messy hard floors, a long-haired pet or family, flat thresholds and no wish to buy dust bags. For raised doorway thresholds a Roborock Saros 20 climbs far better, and the older X12 OmniCyclone is cheaper if you just want the roller mop and bagless dock.
The X12S OmniCyclone is the refresh of the X12 OmniCyclone and sits at the top of Ecovacs's range. It mops with a long roller that's rinsed as it goes, sprays tough stains before scrubbing them and empties into a bagless dock. Ecovacs claims more suction than the X12, a longer roller and a dock that cleans and dries its own dirty-water tank.
All three early testers rate the cleaning highly. CyberShack found it picked up stains other robots miss, and BGR called it excellent on everyday messes, though some really stuck-on stains stayed even with the pre-spray. home&smart ran it daily for a week with long human hair plus added pet hair, and the brush stayed spotless. BGR and CyberShack both had to fix the first map by hand because mirrors confused it. home&smart found it only climbs doorway thresholds of about 2.4cm and called that its main weakness. CyberShack said dust can escape when you empty the bin, so do it outdoors, and BGR found the app poor at warning when the bin is full. BGR also doubts many people will find the upgrade over the X12 OmniCyclone worth paying for.
Before you buy
The questions people ask about this one
Can it cross rugs and raised thresholds between rooms?
Doorway thresholds are the weak spot. home&smart found it tops out at about 2.4cm, and the maker claims about 2.5cm for a single step, per the specifications. CyberShack saw it avoid rugs at first, then clean them once it had learned the floor types.
Does it fit under low furniture?
Only if the gap is roughly 10cm or more. It's 9.8cm tall, per the specifications, so it's about the same height as most robots with a laser turret and much taller than slimline rivals. Measure under your sofa and bed first.
What's it like living with a bagless dock?
No bags to buy, but emptying is hands-on. CyberShack found dust can escape when you empty the bin and suggested doing it outside. BGR found the app poor at warning you when the bin is full, so check it yourself every so often.
Will it avoid cables and pet mess?
CyberShack found it steered round cables and loose objects once the map was fixed. None of the reviews we use has published a proper pet-mess test yet, so for now, pick up anything you don't want run over.
Is it worth it over the X12 OmniCyclone?
Maybe not for everyone. BGR felt the price gap may not justify upgrading, though it liked the stronger suction, pre-spray and longer roller. home&smart noted the X12S has the same low climbing limit as its predecessor.
Alternatives
Other robot vacuums to compare.
DEEBOT X12 OmniCyclone
Why consider it: Same bagless dock and self-rinsing roller idea, and reviewers praised its mopping and obstacle avoidance.
The compromise: Vacuuming reviews are more divided, with weaker results on embedded carpet dirt.
Saros 20
Why consider it: Much better at climbing doorway thresholds and far lower, so it gets under more furniture.
The compromise: It uses a bagged dock, and RTINGS found its obstacle avoidance inconsistent on carpet.
Aqua10 Ultra Roller
Why consider it: Several testers call its roller mopping the best they've seen, and it keeps rugs dry.
The compromise: It's slow and heavy on battery, and owners have reported leaking docks.

Head to head
ECOVACS DEEBOT X12 OmniCyclone vs Deebot X12S OmniCyclone
Our verdict: The X12 is the value pick. Reviewers praised its roller mop, obstacle handling and bagless dock, and it climbs just as low. The X12S adds claimed suction, a longer roller and pre-spray, and BGR felt the price gap may not justify upgrading.
