Tank X11 can easily climb up the steps.
However, in order to fully clean the floor, walls, and waterline, the robot integrates a large-capacity battery and a 4.08L filter basket, so the size of the robot is larger than the width of the normal steps.
It’s hard for the robot to move or turn around on the steps and collect the debris efficiently. So, it’s a design trade-off.
When the robot detects it’s on the steps, it will climb down autonomously and continue cleaning the floor or walls of the pool.
