Cordless Maytronics robots, including the EON and the Liberty 400 and 600, lose their Wi-Fi and Bluetooth connection as soon as they are under water. That is normal. Connect the robot to the app before you put it in, set the cleaning mode or weekly schedule you want, then place it in the pool and it runs the program on its own. When you lift it out, the connection comes back automatically. Corded Dolphins stay connected the whole time because the power supply on the deck does the talking. Note that the Liberty 400 pairs by Bluetooth only, through the MyDolphin Plus app.

Its software. Updates carry the fixes and improvements that keep the robot running as designed, so make sure it is current before any other troubleshooting.

• Install the Maytronics One app and turn on Bluetooth.
• Charge the robot until all three battery bars are solid green, then unplug the charger.
• Sign in to the app with the emailed code, hold the power button for three to five seconds until the LED blinks blue, and pair the robot (your phone should not be connected to another Bluetooth device).
• Run the software update when prompted. Stay next to the robot and keep the app open until it finishes.
• Connect to 2.4 GHz Wi-Fi, or skip it for now. The LED blinks three times and turns solid blue when it is done.

If the robot still misbehaves after the update, contact us and we will walk you through the next steps or arrange service.

With the patented DebrisLock backwash filter. Instead of rinsing the basket after every cycle, you empty it about once a week in about five minutes, which Maytronics puts at up to 20 hours saved a year. The filter compresses and traps fine particles, holds a litre of backwash water to flush debris out easily and opens from the bottom with a double door for quick emptying. DebrisLock ships with the EON 120d and is sold as an add-on for the EON 100.

It uses the DebrisLock basket: an ultra-fine 14-micron filter with a lid that traps debris coming from every direction, a 4-litre capacity, and a sealed chamber that keeps dirt from drifting back into the water. Built into the basket is a backwash system with a 1-litre compression container that locks the debris inside; it runs on its own at the end of each cycle and whenever the filter fills up, so the robot keeps cleaning and you empty the basket about once a week.

Through a filter that catches more fine debris on every pass: filtration from four or five directions, a 4 to 5 litre debris capacity, a larger basket and a closed chamber that keeps what it catches from washing back into the pool. In Maytronics' own 70-minute turbidity tests, starting from the same 7 NTU of cloudiness, the EON 120d left the water up to four times clearer than two other leading robots. Treat that as the manufacturer's figure, but the filter design is why.
