Maytronics Dolphin Explorer E70 · Wybot S3
All robot pool cleaners. Every measure below is plotted against the full class, so a difference can be read against how much the class itself varies.

What each one does on its own.
The Autonomy Ladder is the same five rungs for every robot on the site. A rung describes the conditions a robot handles without you, not how good it is.
Where they actually differ.
The Robovations Score is nine inputs across three pillars, each weighted as shown and each scored so that more is better. A robot can lead on one and trail on another, which is the point of showing them apart. Cost of ownership and data handling are reported on each robot's own page and are never averaged into the score.

Not compared, because fewer than two of these robots carry a published figure: Suction, Runtime, Charge time, Noise, Height.
What the numbers leave out.
The trade-off
What each design gives up to be good at what it is good at.
Cable management remains entirely manual. The E70 stores no cord automatically; 60-foot rope coiled on the deck is a weekly visual reminder, and wind or deck traffic can tangle it.
Waterline coverage costs a third motor. The E70 drives its waterline brush independently of the two drive motors, which is part of what separates it from floor-only cleaners on price and on weight in and out of the water.
Cordless, self-docking, and self-emptying comes at flagship price: $2,999 regular, currently discounted to $2,499 on pre-order, places it above mid-range robotic cleaners; the upgrade premium is substantial if dock automation is not the point.
Waterline reach is mapped, not guaranteed: 3D mapping places cleaner at waterline, but scaling and mineral buildup may require supplemental manual brushing on heavy-stain pools.
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.
- Above-ground pools
- Maytronics specifies the E70 for in-ground pools, and its three-motor drive and swivel cable are set up for in-ground surfaces and depth. Above-ground installations sit outside what the manufacturer specifies for this model.
- Owners avoiding WiFi or app-based control
- The power supply starts a cleaning cycle at the press of a button, but choosing among the 1.5, 2 and 2.5 hour cycles and scheduling them runs through the MyDolphin Plus app. Full hands-off operation assumes connectivity.
- Pools longer than 50 feet
- Maytronics specifies the E70 for in-ground pools up to 50 feet, which the 60 ft cable is sized around. Longer pools sit outside the stated envelope.
- Decks with no GFCI-protected outlet in reach
- The E70 is mains-fed: the power supply sits on the deck and runs the robot over the cable. It needs a GFCI-protected outlet, which is code-required for pool equipment, and an extension cord is not a way to close the distance to a distant one. The fix is a properly located outlet.
- Above-ground pools under 5,000 gallons
- Flagship footprint and self-emptying dock designed for in-ground depth/slope. Minimal evidence for shallow above-ground use; manufacturer guidance unclear.
- Pools with complex obstacles or tight corners
- 3D mapping excels on open floor/wall geometry. Narrow steps, shallow ledges, or tight spa-adjacent areas may slow coverage. Dock placement must clear furniture/edges.
- Owners unwilling to manage dock placement and seasonal storage
- Self-emptying dock requires dedicated outlet, winter storage, or year-round protection in cold climates. Cable-free robot still needs dock positioning for effectiveness.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
- After every cleaning cycle: Lift the robot out and rinse the multi-layer filter basket through the top-access opening. Maytronics’ instruction is to rinse after each cycle; a loaded basket costs suction. The panels are washable and reusable, so there is nothing to buy on a schedule.
- After every cycle: Look over the cable for cuts or abrasion and coil it on the caddy so it is not a trip hazard on the deck.
- Monthly: Check the brushes and the motor housings for hair, leaves and grit, and clear anything wrapped around the drive.
- Seasonally: Store the robot, cable and power supply indoors out of freeze and direct sun.
- Every use: Remove the cleaner from the pool before anyone swims.
- After every use: Empty debris basket if full; check dock inlet for clogs.
- Weekly: Rinse pre-filter (dock assists); visual brush inspection for wear.
- Monthly: Hand-rinse main filter cartridge if dock suction shows weakness; wipe the dock’s solar panel clear of leaves and waterline film so charging is not throttled.
- Seasonally: Full filter cartridge replacement (~$40-60); dock winterization cover or storage.
- Annually: Brush wear assessment (~$30-50 replacement if needed).
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.
