Among the most renowned brands in this industry, Roborock has earned a stellar reputation for its innovative and efficient robotic vacuum models. However, even the most advanced technology can face occasional challenges, and one common issue that Roborock users may encounter is the frustration of a robot vacuum not charging. In this troubleshooting guide, we will delve into the reasons behind this problem and explore practical solutions to get your trusty Roborock back on its feet, or rather, its wheels, ensuring your home stays as clean and clutter-free as ever.

Over the last few months, the Xiaomi Roborock S7 has skyrocketed in popularity as a feature-rich robotic floor cleaner. Its remarkable cleaning performance and budget-friendly price have made it the go-to choice for numerous customers. What sets this robot vacuum cleaner apart is its compatibility with Amazon Alexa, allowing users to effortlessly control it through voice commands.

Why is My Xiaomi Roborock Not Charging?

The prevailing issue that often leads to Roborock vacuum cleaners failing to charge is the build-up of dirt on the charging sensors. To remedy this, if your Xiaomi Roborock is experiencing charging issues on its dock, it’s imperative to thoroughly clean all four contact pins on both the charging station and the robot itself.

Beyond this common cause, there exists a spectrum of other potential factors contributing to the Xiaomi Roborock not charging, which includes a malfunctioning wall outlet, a damaged charging cable, out-of-date firmware, a faulty battery, or even a defective motherboard.

What is Roborock Error 12?

When your Xiaomi Roborock carpet cleaner displays Error 12, it’s signaling a low battery situation. To resume your cleaning tasks, it’s essential to charge your device and ensure it has adequate power.

What is Roborock Error 13?

When Error 13 surfaces on your Roborock, it’s signaling an issue where the battery isn’t charging because the charging station is providing insufficient current.

To address this concern, it’s essential to clean all the charging sensors on both the charging station and the robot. This maintenance step can help resolve the problem and get your Roborock back to its efficient cleaning operation.

How To Fix Roborock Not Charging? – 5 Easy Fixes

Recognizing the dirt accumulating on your floor due to your non-charging Roborock robotic vacuum can be frustrating. But fear not, as we present these practical solutions to breathe new life into your robotic helper.

1. Clean All Contacts

Within your Roborock charging dock, you’ll notice two metal sensors. Similarly, when you turn your robot over, you’ll find comparable charging sensors on its underside. These sensors play a vital role in facilitating the flow of electricity between your robotic cleaner and its docking station. However, as your robot diligently tackles dust and debris, these sensors can accumulate dirt and grime over time.

If any sticky particles find their way onto the floor, they may adhere to your robot, creating an insulating layer on both the robot’s charging pins and the docking station’s sensors. To rectify this, here’s a simple cleaning solution: dip a cotton swab in rubbing alcohol and delicately cleanse the metal sensors on your Xiaomi Roborock. Don’t forget to extend this cleaning process to the charging dock sensors as well.

By meticulously tending to all four sensors on your Roborock robot and charging dock, you’ll likely find that the charging issue is resolved, ensuring your robotic companion is back to its efficient operation.

2. Align the Charging Contacts

Another potential factor behind the Xiaomi Roborock not charging issue is the misalignment of the charging pins. When positioning your Roborock on the charging dock, it’s crucial to ensure that all contact points firmly make contact with the metal sensors of the dock.

If any of these contact points fail to connect with their corresponding sensor, the Xiaomi Roborock will not initiate the charging process. In such instances, gently lift your Xiaomi Roborock and carefully place it back on the charging dock, ensuring that all four contact points make proper contact with the sensors of the dock. This alignment adjustment should help resolve the charging problem effectively.

3. Inspect Charging Cable and Wall Outlet

In the event that you’ve already cleaned the charging sensors and ensured proper alignment, but your Roborock charging dock remains unlit, it’s time to turn your attention to the charging cable and the wall outlet.

Begin by unplugging the charger from the wall outlet and then plug it into a different electrical outlet. If your Xiaomi Roborock starts charging on the alternative outlet, this signals an issue with your initial wall outlet. In such a scenario, it’s advisable to reach out to an electrician for the necessary repairs.

However, if your Xiaomi Roborock continues not to charge on the new outlet, it indicates a potential problem with your charger or charging cable. Inspect these components closely, and if you identify any physical damage, it’s recommended to replace them with new ones to restore the charging functionality.

4. Replace the Battery

The Xiaomi Roborock is equipped with a 5200mAh lithium-ion battery, affording your robot a runtime of 150 minutes. Nevertheless, like all lithium-ion batteries, its capacity naturally diminishes with time and usage.

If you’ve been using your Roborock extensively for over a year, there’s a possibility that the battery life has declined, causing your Roborock to struggle with holding a charge. To verify this, attempt a 24-hour charging cycle. If your Xiaomi Roborock still fails to retain the charge and drains rapidly, the solution may lie in replacing the battery with a new one.

You can conveniently source a genuine Xiaomi Roborock battery from online marketplaces such as Amazon or AliExpress. It’s imperative to ensure that you acquire a battery with the same model number as your current Xiaomi Roborock.

The installation process for a new battery is relatively straightforward. You’ll need to access the bottom panel of your Xiaomi Roborock and perform a straightforward swap, replacing the old battery with the new one to rejuvenate your robot’s performance.

5. Contact Roborock Customer Support

After diligently attempting the previously mentioned solutions without success, if your Xiaomi Roborock still refuses to charge, it suggests the presence of a hardware-related problem. In such instances, the most viable course of action is to reach out to Xiaomi Roborock’s customer support.

It’s worth noting that Xiaomi provides a one-year warranty for their Roborock robotic vacuum cleaners. If your Xiaomi Roborock is within the warranty period, you have the opportunity to avail of a free replacement or repair service to rectify the issue.


Error 13, a common occurrence in Roborock devices, signifies a failure to charge due to low voltage issues. One practical solution to address this is to cleanse the charging sensors using either rubbing alcohol or vodka.

If your Roborock’s charging dock displays no illumination, it hints at potential faults within the dock itself or issues stemming from the wall outlet. To confirm the charger’s status, consider testing it in a different outlet.

Exhaust all previously suggested solutions to resolve the problem. Should none of them prove effective, your best recourse is to initiate contact with the customer support team to arrange for the necessary repairs.
