All robot pool cleaners. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.
Where each one suits you.
The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.
| Condition | Wybot C2 | Maytronics Dolphin Na… |
|---|---|---|
| Pool type | ||
| In-ground | GoodWybot designs and rates the C2 specifically for in-ground pools up to 2,152 sq ft; this matches its documented target use. | GoodDesigned for in-ground pools; wall-climbing and floor coverage engineered for this category. |
| Above-groundthey differ | DependsWybot documents this model for in-ground pools only; no above-ground rating or compatibility statement was found in the sources reviewed. | PoorWeight and suction cup design do not fit above-ground sidewalls or inflatable pool walls. |
| Mixed setupthey differ | DependsWith no above-ground rating documented, a mixed setup only has confirmed coverage for the in-ground portion of the pool. | GoodIn-ground pools are the primary design; above-ground operation not recommended. |
| Pool size | ||
| Small (< 400 sqft) | GoodWell inside the 2,152 sq ft rated coverage; a full cycle at up to 180 minutes has ample margin for this size. | GoodSmall pools (under 10,000 gallons) easily covered by single pass; 50-foot cord more than adequate. |
| Medium (400 – 800) | GoodComfortably within the 2,152 sq ft rated area, with the 180-minute Eco-mode runtime enough for a complete cycle. | Good12,000–25,000-gallon pools are the design target. Full coverage in one cord placement typical. |
| Large (> 800) | DependsWybot's rating tops out at 2,152 sq ft; pools well above that may exceed a single 180-minute cycle's coverage. | DependsPools above 33 feet require repositioning cord or dual-unit deployment for complete coverage. |
| Debris load | ||
| Fine (sand / silt) | GoodIndependent testing found the ultra-fine 10-micron filter stage makes a noticeable difference on fine sediment compared to a single 180-micron basket. | GoodFine-debris brush is the Nautilus Plus specialty; sand and silt are primary design targets. |
| Leaves / large debristhey differ | GoodNo leaves-specific test was documented for the C2; the 180-micron primary stage should catch larger debris, but this was not verified independently. | DependsHandles moderate leaf load but fine-brush clogs quickly in heavy-leaf seasons; weekly cleaning needed. |
| Algae / heavy foulingthey differ | GoodIndependent testing specifically credits the dual-layer filtration with a noticeable difference on light algae, beyond what a single-stage filter catches. | DependsAlgae-heavy pools require frequent filter maintenance; brush can clog, slowing collection velocity. |
| Coverage you want | ||
| Floor only | GoodEven without mapping, independent full-cycle testing found the C2 covers a pool thoroughly on the basic floor-cleaning modes. | GoodBrush-driven floor coverage is standard; reaches all floor geometries within cord reach. |
| Floor + wallsthey differ | DependsWall coverage is one of seven preset modes, not an adaptive route, so the owner must choose the right one. | GoodWall-climbing design covers vertical surfaces; floor-to-wall transition is proven in thousands of pools. |
| Floor + walls + waterline | DependsFull floor, wall and waterline coverage means choosing the right preset mode; there is no camera to plan it. | DependsWaterline coverage is incidental (suction cups contact walls); not engineered as primary target like floor or walls. |
A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
What the score is built from.
Nine inputs across three pillars, each weighted as shown and each scored so more is better. A robot can lead on one and trail on another, which is the point of showing them apart.

Not compared, because fewer than two of these robots carry a published figure: Runtime, Charge time, Noise.
What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
Wybot C2
No camera, no mapping: seven preset modes replace a perception system, so coverage quality tracks the mode the owner selects, not the robot’s own judgment.
The added 10-micron filter stage catches finer sediment than a single-basket cleaner, but a three-hour charge against a three-hour runtime still caps use at one cycle per half day.
At 17.6 lb wet, the machine that documents step and slope coverage is also the one an owner has to physically lift out every time.
Skipping the AI camera keeps the price roughly $200 below the C2 Vision, and gives up debris-adaptive path planning to do it.
Maytronics Dolphin Nautilus CC Plus
The fine-porosity cartridges that capture silt and sand are the same porosity that loads quickly. In an algae bloom they can fill inside a single cycle, so the after-every-use rinse is what keeps pickup from falling off.
Cord-based operation eliminates wireless convenience but removes dependency on app uptime and cloud connectivity.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
Wybot C2
- Pools larger than the 2,152 sq ft rated coverage
- Wybot rates the C2 by area, up to 2,152 sq ft, and the machine has no mapping to compensate; larger or irregular pools risk incomplete coverage.
- Owners who want the machine to sense and adapt to debris
- The plain C2 carries no camera at all; adaptive debris detection and selective zone avoidance are reserved for the C2 Vision, priced roughly $200 higher.
- Owners who need back-to-back cleaning cycles without downtime
- A roughly three-hour charge against up to three hours of runtime in Eco mode means only one full cleaning cycle fits comfortably in a half day.
- Owners who cannot lift a 17.6 lb wet unit from the pool
- At 17.6 lb, the C2 is a real lift once it is full of water and pulled from the pool after every cycle, with no self-emptying dock.
Maytronics Dolphin Nautilus CC Plus
- Above-ground or inflatable pools
- Weight and wall-climbing design do not fit above-ground sidewalls. Suction-based robots are standard for inflatable pools.
- Pools with irregular stone or tile edges
- Navigation scans the pool rather than building a map, so covering a heavily irregular shape depends on cycle length rather than a planned route, and crevices along a rough stone edge can be left.
- Owners wanting a cleaner they never handle
- Maytronics instructs owners to rinse the filter after every use, and the unit is lifted in and out of the pool by hand each cycle. There is no self-emptying base.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Wybot C2
- After every use: Rinse the 180-micron filter basket and the 10-micron ultra-fine filter cotton with a hose before debris dries in place.
- After every use: Recharge the battery; Wybot rates a full charge at about 3 hours. Keep the charging port dry and clean before connecting.
- As needed: Replace the C2 filter cotton when rinsing no longer restores water flow ($12.99-19.99 direct from Wybot); no replacement interval is published.
- As needed: Check the tires and drive belts for trapped hair or grit; both are sold as replacement parts on Wybot’s store.
- Seasonally: Take the robot out of service when the pool closes; store it indoors, away from freezing temperatures.
Maytronics Dolphin Nautilus CC Plus
- After every use: Lift the unit out, open the top-load basket, and rinse the filter cartridges with a hose; Maytronics instructs this after each cycle, and the quick water release is built for it.
- After every use: Unwind the 60 ft floating cable and coil it loosely so the next run starts tangle-free.
- Weekly: Check the cable for cuts, kinks, or abrasion.
- Every 3-6 months: Replace the filter cartridges as the mesh degrades (~$28-35 per cartridge).
- Annually: Replace the two rotating scrubbing brushes as the bristles wear down (roughly $45 per set).
- Seasonally: Inspect the drive tracks for wear, then store the unit and its power supply indoors, out of freezing conditions, when the pool is closed.
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.

Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
