Generally speaking, the RoboVac vacuum will not fall down stairs as it is equipped with three/four drop sensors that prevent RoboVac from tumbling down stairs or steep drops. Please refer to the following article to learn more about the drop sensors.

Will RoboVac fall down stairs when working?

If your RoboVac fell down stairs, please try the following troubleshooting steps:

• Please do not place the charging base near the stairs to avoid the risk of the RoboVac falling off the stairs during the recharging process.

• The drop sensors may work less effectively if they are dirty or if the RoboVac is running on carpeted / reflective / very dark-colored floors.

• In daily maintenance, we highly recommend regularly cleaning all of the drop sensors with a clean dry cloth.

For Bounce/iPath Navigations models like L35/LR30 Hybrid+ etc. It has three drop sensors.

For Gyro Navigation models like G30, it has four drop sensors. For iPath Navigation models, only the L70 and X8 have four drop sensors.

If the issue is due to the environment(eg:carpeted stairs/very dark-colored floors), it is recommended to do the following:

• Place a physical barrier or boundary strip( for RoboVac models like the G30 Edge) to block off potential areas where the RoboVac may fall down.

• Set a "No-go" zone(for iPath Laser Mapping RoboVac models like the L35 Hybrid) via the eufy Clean app.

If these troubleshooting steps were unable to resolve your issue, please contact eufy support with a picture of the stairs area where the RoboVac fell down and estimate the height of the first step.
