1.Fail to activcate the robotic vacuum.

* Make sure the battery is fully charged. * Replace the batteries in the remote control. * Make sure the remote control is within a range of 5 m/16 ft from the robotic vacuum when controlling.

2.The remote isn't working.

* Replace the batteries in the remote control. * Make sure the battery is fully charged. * Make sure the remote control is within a range of 5 m/16 ft from the robotic vacuum when controlling.

3.The robotic vacuum suddenly stops working.

* Check if the robotic vacuum gets trapped or stuck. * Check if the battery is running out. * Make sure you didn't pause the device by mistake.

4.Fail to start the scheduled cleaning.

* Make sure the battery is fully charged. （ The scheduled cleaning can be started when the remaining capacity of batteries reaches at least 15%） * Make sure you didn't cancel the schedule by mistake.

5.The suction power is weak.

* Adjust the suction level by pressing MIN and MAX on the remote control. * Check if any particles are blocking the suction inlet. * Empty the dust bin and clean the filters. * Replace the Sponge and HEPA filters.

6.Making noises.

* The robotic vacuum will create noises when operating, which is normal. * If a sharp noise is heard, please check if anything is tangled in the main brush, side brushes, and wheels. * Check if there are objects in the dust bin that could create noises.

7.The robotic vacuum cannot be charged.

* Make sure the power indicator light on the charging base is lit up. * Check if the charging pins on the robotic vacuum are aligned with the ones on the charging base while charging. * Dust off the charging pins with a dry cloth.

8.Fail to return to the charging base.

* Remove any objects near the charging base that block the robotic vacuum going back for recharging. * If the charging base is located far away, the robotic vacuum will need more time to return. Please be patient as it works its way back. * Make sure the battery level is not critically low or empty. * Clean the sensors on the bumper of the robotic vacuum and the charging base.

9.The main brush cannot work.

* Check if the main brush is stuck by objects; If so, remove them and clean the brush. * Make sure the main brush and brush gurad are installed properly.

10.The momvements or travel path are abnormal.

* Clean the sensors with a damp cloth. * Directly contact us at support@Yunqis.com

11.The cleaning time gets shorter or less than 150 minutes.

* The cleaning time may vary from the cleaning mode, suction power level, and the type of floor that the robotic vacuum cleans. * If the robotic vacuum is not fully charged, then the cleaning time will be shorter.
