If your Roborock robot vacuum won’t charge on its dock, charges slowly or won’t switch on, these are the checks from Roborock’s manuals.

What This Problem Means

The robot isn’t getting power from its dock, the contacts aren’t touching properly, or the robot has slowed charging to protect its battery.

Common Symptoms

• The robot won’t switch on
• The battery level doesn’t rise on the dock
• Charging takes much longer than usual
• The robot won’t carry on cleaning after it recharges

Safe Checks You Can Try

1. Check the dock has power

Roborock’s manuals say to check both ends of the power cord (or, on the Q10 S5 and Q7 M5, the power adapter) are properly connected. On the Saros 20, Saros 20 Neo, Saros Z70, Saros 10, Qrevo Curv 2 Pro, Qrevo Curv, Qrevo Edge 2, Qrevo 2 Pro, Qrevo S Pro, Qrevo S5V and QV 35S, also check the dock’s status indicator light is on: it is on when the dock has power and goes off while the robot charges. On the Qrevo S5V and QV 35S, the light is off or dim during Do Not Disturb hours (22:00 to 08:00 by default), so check it outside those hours.

2. Clean the charging contacts

Poor contact stops charging and dirty contacts slow it down. Clean the charging contacts on the dock and on the robot, wiping them with a soft, dry cloth.

3. Seat the robot on the dock

If the robot is so flat it won’t switch on, Roborock says to put it on the dock and charge it before use.

4. Check the room temperature

Only use the robot between 4 and 40°C. Roborock says that when it is used at high or low temperatures, the robot automatically reduces its charging speed to extend battery life.

5. Keep the power cord out of the way

If the power cord hangs down to the floor, the robot may catch it and move or disconnect the dock. Tidy the cord behind the dock.

If it won’t carry on cleaning after charging

Roborock’s manuals say Do Not Disturb (DND) mode stops the robot topping up and carrying on. A robot you put on the dock by hand, or send to the dock with a button, won’t resume the clean either. Scheduled cleans only start when the battery is above 15% (20% on the Q7).

Charging questions

The robot draws a small amount of power while it sits on the dock, to keep the battery in good condition; Roborock says the power use is extremely low. There’s no need to charge it for 16 hours before the first few cleans: Roborock says lithium-ion batteries have no memory effect, so it can be used once fully charged.

When To Contact Support

If none of these checks fix it, contact Roborock through its UK contact page, with your robot’s model and the serial number from the sticker underneath it.
