How do I factory reset my Roborock S5?
For model S5 :
Step 1. Hold the recharge button for 3-5 seconds.
Step 2. Use a pin to press the reset button next to wifi LED just once，and power button, recharge and spot cleaning button's light will be out. When you are doing this, please make sure recharge button is still under your finger's holding without moving.
Step 3. Keep holding recharge button for 5 seconds after you press reset button until power button blinks again and you hear the tone restore, and then you could remove the finger.
1. Factory default restore will disconnect RoboVac from wifi. Please re-add it after factory default restore.
2. Factory default restore will also make RoboVac's firmware version come back to original one when it was made in factory. After factory default restore, you could go to RoboVac's setting--general setting--check for updates to upgrade its firmware to latest one.
