The answer
What to know.
Follow these steps to prepare your Dolphin EON 100/120d for its first cleaning cycle.
-
Step 1Connect the charger
Attach the charger to the robot, then plug it into an electrical outlet.
-
Step 2Fully charge the robot
Wait until all 3 charge bars show solid green. The robot needs a full charge before you get started.
-
Step 3Disconnect the charger
Unplug the charger from both the robot and the electrical outlet.
-
Step 4Install the app
Install the MaytronicsOne app to set up the connection. The robot supports Bluetooth and 2.4 GHz Wi-Fi only.
Neither Wi-Fi nor Bluetooth stays connected while the robot operates in the water.

-
Step 5: Pair the robot\n Hold the power button for 3-5 seconds to enable Bluetooth pairing. Then pair the robot in the app.
-
Step 6Update the software if prompted
If an update prompt appears, complete the software update noted on the sticker.
-
Step 7Add your Pool Features
Work through the app's setup instructions, including adding your Pool Features.
-
Step 8Select Smart Mode
After connecting the robot and adding your Pool Features, open Cleaning Modes and choose Smart Mode to start the calibration scan.
During this first Smart Mode cycle, the robot scans your pool and builds a customized cleaning program based on its shape and features.
-
Step 9Put the robot in the pool
Place the robot in the water. Cleaning will start automatically within 30 seconds. Start with the robot on the pool floor for the best cleaning results.
If your pool has a lot of debris, you may need several shorter cleaning cycles. Clean the filter between those cycles to help maintain cleaning efficiency.
When both the scan and the Smart Mode cycle are finished, remove the robot from the pool and reconnect to the app. The app will then display the suggested cycle, cycle time, and scanning pattern.
