Fixing Roborock Not Charging – 10 Steps

Below, you’ll find a step-by-step guide to troubleshoot and resolve the charging problem with your Roborock vacuum.

These steps will help you get your vacuum cleaner charging properly again.

1. Check the Wall Outlet

3. Power Cycle The Robot Vacuum & the Charging Dock

Power cycling the robot vacuum and charging dock is a valuable troubleshooting step that is worth a try.

It provides a fresh start, clearing temporary glitches and errors in their internal systems.

This process refreshes software, resets minor malfunctions, and enhances overall performance and functionality.

Power Cycling the Robot Vacuum

Follow the steps provided below to power cycle your vacuum:

  1. Begin by turning off the robot vacuum.
  2. Next, take out the dust bin from the robot.
  3. Remove the wheel from the robot.
  4. Followed by detaching brushes.
  5. Using a screwdriver, carefully open the battery cover.
  6. Locate the robot’s battery and proceed to remove it.
  7. Allow a waiting period of 60 seconds before reinserting the battery and all other components that were previously removed.

Power Cycling the Charging Dock

Now, let’s move on to power cycling the charging station/dock. This is a straightforward process as compared to the above process:

  1. Start by unplugging the charging dock from the wall outlet.
  2. Wait patiently for a duration of 60 seconds.
  3. After the waiting period, plug the charging dock back into the wall outlet.

4. Verify the Station’s Indicator Light

Check the indicator light on the charging station. It’s usually sold as white when it’s ready to charge and off when the robot is docked.

If the light is not as expected, it may indicate a problem with the station or the robot’s docking alignment.

Proceed to the next step for realignment.

5. Realign the Charging Contacts

Sometimes, you might have to manually put your robot vacuum on its charging dock. Making sure it’s properly aligned with the charging contacts is crucial for a smooth charging experience.

Here’s how to do it:

  • First, turn off your robot vacuum to avoid any sudden movements.
  • Put the charging dock on a flat surface close to where your robot usually parks.
  • Clear the area around the dock so nothing gets in the way.

Detaching Mop During Charging

If your robot has a mop attachment, take it off for now. Mop attachments can lift the robot slightly, which can mess up the alignment.

Carefully pick up your robot and place it on the charging dock. Make sure the front and back wheels line up with the docking grooves or guides on the charging station.

Now, take a good look to see if the robot is sitting nicely on the dock. Check that the charging contacts on the bottom of the robot are touching the ones on the charging station.

6. Inspect Charging Base Pins

Now, let’s talk about taking a closer look at those tiny but critical pins on your robot vacuum’s charging base. They are responsible for making sure your vacuum gets the juice it needs.

Here’s what you should do:

  • First off, make sure the charging base is unplugged.
  • Then, get down there and have a good look at those pins.
  • Check if any of them seem loose or damaged.
  • Loose pins can mess with the whole charging process, and damaged ones can be even worse.

If you do spot any issues with the pins, don’t worry too much. Just reach out to the manufacturer for replacements or repair instructions.

They’ll be able to guide you on what to do next.

7. Update the Firmware

Regularly updating the robot vacuum’s firmware is essential. Manufacturers release updates to fix bugs and improve functionality.

Check the manufacturer’s website or app for the latest firmware and follow their instructions to update your device.

To update your Roborock vacuum, you will need to use the Roborock app or the Xiaomi Home app.

Using the Roborock app:

  1. Open the Roborock app and tap on the Vacuum icon.
  2. Tap on the Settings icon (gear icon).
  3. Tap on Software Update.

  4. If there is an update available, the app will automatically download and install it.
  5. Once the update is complete, your Roborock vacuum will restart.

8. Replacing Battery

Roborock vacuum cleaners have lithium-ion batteries, similar to those found in our everyday gadgets. Over time, these batteries can wear out, especially with regular use.

When troubleshooting the ‘not charging’ issue, it’s essential to consider this factor, as it might be due to a degraded battery. In such cases, a practical solution is to replace the battery.

For battery replacement:

  • Remove the robot from the charging dock.
  • Flip the robot over.
  • Unscrew eight screws securing the bottom cover.
  • Lift and set aside the back cover.
  • Disconnect the battery strap.
  • Disconnect the battery connector.
  • Insert the new battery, ensuring it clicks in place.
  • Reassemble the robot by replacing the back cover and screws.

This can clear out any software glitches that may be causing charging problems.

For resetting your Roborock Vacuum:

  • Hold the home icon button for 3-5 seconds.
  • While holding the home button, press the reset button next to the Wi-Fi LED.
  • The lights on the buttons will turn off.

  • Release the home button.

10. Evaluate the Motherboard

When all other troubleshooting steps, including factory resetting, have failed to resolve the charging issue with your robot vacuum, it becomes crucial to examine the motherboard.

The motherboard functions as the central control unit of the robot and, like any electronic component, can develop problems over time.

Here’s what to do:
