EON 100
3 independent reviewsRead the findings →The cheaper of Dolphin's cordless EON robots, for medium to large pools. It cleans floors and the waterline well and rarely gets stuck. It's heavy to lift out, though, and gives steps only a quick pass.

Feedback
What reviewers found
There's no English-language test yet. Three French reviewers ran it in their own pools: Meilleure Innovation in a lined pool with three narrow steps and a curved ledge, Mon Robot Piscine in an in-ground pool just under 10 metres long, and GohanBlog over several weeks. All three liked the floor cleaning and the easy filter. Steps, awkward shapes and how methodical the navigation is divide them. Only Meilleure Innovation measured the battery.

Floor, wall and waterline
Reviewers rate it highlyFloors came out clean in every test: Meilleure Innovation saw every pebble lifted and GohanBlog found floor, walls and waterline cleaned evenly. On the waterline, Mon Robot Piscine found it helps with a thin greasy line but you'll still need a sponge now and then.
Debris
Mixed resultsLeaves, insects and grit were no trouble for Meilleure Innovation or GohanBlog. The finest dirt is the limit: Meilleure Innovation says the 70-micron basket misses dust suspended in the water, and Mon Robot Piscine saw some pollen-like material left behind.
Coverage and navigation
Mixed resultsIt reaches everywhere without getting stuck, per Meilleure Innovation, and GohanBlog found few missed spots. Steps are the weak point: Meilleure Innovation saw it clean them only briefly, and Mon Robot Piscine found it less at ease on steps and complicated pool shapes.
Battery and charging
Mixed resultsRun time is generous: Meilleure Innovation got 2 hours 49 minutes from a part-charged battery and GohanBlog managed several cycles per charge. Both found the plug-in charging fiddly, with a cap to refit and a connector that takes practice.
Filter and retrieval
Mixed resultsEmptying the top-loading basket is quick, per Mon Robot Piscine and GohanBlog. Getting it out is harder: Meilleure Innovation found the 10kg robot heavy once waterlogged, and Mon Robot Piscine found retrieval awkward in a deep pool without the extra-cost Click-Up button.
Pool types it suits
Mixed resultsMeilleure Innovation found it handled a lined pool with narrow steps and a curved safety ledge, even reaching shallow areas. Mon Robot Piscine found it less comfortable in pools with complicated shapes, so simpler layouts suit it best.
Reliability and support
Not enough evidenceOnly Meilleure Innovation looked at support, praising the dealer network but finding no EON-specific wear parts in the spares catalogue. None of the reviews we use has run it long-term.
Value
Not enough evidenceOnly Meilleure Innovation judged value, noting that rivals at the same price add a charging dock and finer filtration, and that the optional accessories add up quickly.
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
Strong on floors, weaker on fine dust
Meilleure Innovation saw it pick up every pebble in its test, plus leaves, insects and dog hair, and GohanBlog said it collected leaves, small debris and fine dust alike. The two French testers who looked closely at the finest dirt did find limits. Meilleure Innovation said the 70-micron basket catches visible and semi-fine dirt but not dust suspended in the water, and Mon Robot Piscine found a little very fine material, like pollen, stayed behind. If pollen or building dust is your problem, this basket won't clear it all.
Steps split the reviewers
Meilleure Innovation found it climbs steps but cleans them quickly, without the patient back-and-forth the tester wanted. It also moved sideways like a crab to follow a curved safety ledge. Mon Robot Piscine called it less at ease on steps and complicated pool shapes, while GohanBlog raised no complaints. Pool shape probably explains some of that. If your steps collect the most dirt, expect to brush them yourself now and then.
Never stuck, but the route looks random
Meilleure Innovation reported no jams and no need to rescue it at any point in testing. Its maze mode moved with no visible logic, though, and the line-by-line mode was more methodical. GohanBlog felt the mapping understood the pool's layout and adapted its route, while Mon Robot Piscine found the map in the app basic. In practice, that's good coverage without babysitting, even if its path looks odd from the poolside.
Battery holds up, charging is fiddly
Meilleure Innovation got 2 hours 49 minutes from a battery charged to about 75%, and a full recharge took just over two hours. GohanBlog managed several cleaning cycles before it needed charging again. Both found the charging plug a weak point. Positioning the cable took some getting used to, GohanBlog said, and Meilleure Innovation noted you have to charge it dry and remember to refit the protective cap.
Getting it out is the chore
There's no dock, and the Click-Up button that calls it to the surface is sold separately. Meilleure Innovation found the 10kg robot heavier than many rivals once it's full of water, though the arched handle helps. Mon Robot Piscine said getting it out without the Click-Up isn't comfortable, especially in a deeper pool. Budget for the button if your deep end is out of arm's reach.

Our take
Should you buy the EON 100?
Best for: Pools with curves, steps or shallow sitting ledges. Skip it if: You do not want to retrieve it with a hook after cleaning.
Buy it if your pool has steps, a sun shelf or awkward curves and you want to stop dragging a cable about, and budget for the retrieval button if your deep end is out of reach. The Aiper Scuba V3 finds debris by camera and suits a plain rectangle, and the EON 120d's sealed filter is the step up for fine dust.
The EON 100 is the cheaper of Dolphin's two cordless EON robots, launched in January. It has the same body as the EON 120d, the same jets that help it climb steps and the same reach onto ledges as shallow as 20cm, but a plain top-loading basket you rinse yourself instead of the self-cleaning filter. It is rated for pools up to fifteen metres, and a scheduler spreads one charge over a week.
Three French reviewers ran it in their own pools and all liked the floor cleaning. Meilleure Innovation saw every pebble lifted, plus leaves, insects and dog hair, and reported no jams at any point.

Meilleure Innovation saw it clean them only briefly and Mon Robot Piscine found it less at ease on steps and complicated shapes, while GohanBlog raised no complaints. There is no charging dock, the button that calls it to the edge costs extra, and Meilleure Innovation found the 10kg robot heavy to lift out once full of water.

Before you buy
The questions people ask about this one
Does it climb walls and clean the waterline?
Yes. It climbs walls and scrubs the waterline with a brush, per the specifications. Meilleure Innovation found the brushing lifted most of the grime there, and GohanBlog said it cleared dirt along the waterline. Mon Robot Piscine found it helps with a thin greasy or limescale line but doesn't replace a wipe with a sponge now and then.
Is it cordless, and how long does a charge last?
It's fully cordless, with cycles of 1.5, 2 or 2.5 hours and a scheduler that spreads cleans across a week, per the specifications. Meilleure Innovation measured 2 hours 49 minutes from a battery at about 75%, and a full recharge in just over two hours.
How do I get it out of the pool?
By hand, unless you buy the Click-Up button that calls it to the edge. There's no dock. Meilleure Innovation found the robot heavy once waterlogged but liked the handle, and Mon Robot Piscine found retrieval awkward in a deeper pool without the button.
Can it cope with steps and a deep end?
It's built to reach steps and ledges as shallow as 20cm, per the specifications. Meilleure Innovation saw it climb three narrow steps but clean them only briefly, and Mon Robot Piscine found it less at ease on steps and complex shapes. Expect it to reach them, not to scrub them thoroughly.
How do I clean the filter?
Open the top, lift out the basket and rinse it under a hose. Mon Robot Piscine and GohanBlog both found this quick. Meilleure Innovation singled out the full-filter light on the body as a rare and useful touch.
Does it need an app?
The Maytronics One app handles schedules, cleaning modes and alerts, per the specifications. GohanBlog started out sceptical and quickly came round. Mon Robot Piscine found it handy for starting cycles and checking the battery, though far from advanced, and Meilleure Innovation missed a precise battery percentage.
Alternatives
Other robotic pool cleaners to compare.
Scuba V3
Why consider it: Three testers found its camera really does help it find and clear debris on floors, walls and the waterline.
The compromise: You get about 10 minutes to collect it after a run before it sinks.
EON 120d
Why consider it: PCWorld found its sealed DebrisLock basket held on to grit well, and the supplied clicker reliably called it to the waterline.
The compromise: That filter was hard to clean, and PCWorld's unit tipped over often and twice failed to start.
AquaSense 2
Why consider it: Testers liked its floor and wall cleaning, and it floats to the edge when it's done, so there's no hook needed.
The compromise: It doesn't skim, and steps and fine silt were hit and miss in testing.
