9. Q: The cleaner can't clear a 2cm-high step or a step almost 2cm high.
Boilerplate: Hello! If there are small steps in your home and their height almost reaches the
cleaner's obstacle clearance limit, which results in the cleaner being unable to traverse the
steps, it may be due to the ground environment. We recommend that you use a cloth with
detergent to wipe the steps and wheels. If the cleaner still can't pass the steps, we recommend
you create a small slope to reduce the wear of the robotic cleaner's main wheels, and to ensure
the normal use of the robot. Thank you for your support. If you have any issues during use of
the cleaner, please leave a message at any time!
10. Q: The robotic cleaner gets stuck when it encounters a circular iron frame of about 2.5cm.
What's the solution? (Updated on March 26, 2018)
It is recommended that the user purchase a bumper strip (as shown below). After attached to
the cleaner, the height of the iron frame can trigger the cleaner's collision bumper.
