Why does TP-Link Robot Vacuum fall down the stairs?

Introduction

Robot vacuums typically don’t fall down stairs because they’re designed to use downward-facing sensors to detect and avoid stairs. If it happens, it might be caused by the abnormal cliff sensor, which prevents the Robot Vacuum from falling.

Requirements

• A clean cloth to wipe sensor
• Tapo Robot Vacuum

Troubleshooting

The Robot Vacuum’s sensor is set on the bottom of the robot. Typically located beneath the front bumper, featuring a protruding edge.

You may try the following troubleshooting steps:

• Turn the robot vacuum over, and wipe the cliff sensor with a damp cloth.
• Keep the robot vacuum upside down, and press the Start button to check if the main wheels stop spinning after a brief spin and an alarm sound.

Note: The Cliff sensor cannot detect on black floors.
