Generally, a Eufy Robovac stops charging when dust and debris block the connection between your RoboVac and its charging dock. Also, if there’s a faulty dock, dead battery, or adapter, it may not charge.
Although Eufy RoboVacs have made a great name in the robot vacuum world, I found one of my RoboVacs stopped charging during our testing. And it raised several concerns about why it’s not charging and what’s causing this error.
In this guide, I put everything you need to troubleshoot your RoboVac when it stops charging. I have also included the causes that lead to this problem.
Why Is My Eufy Robovac Not Charging?
If your Eufy RoboVac is not charging, the vacuum or dock charging contacts are dirty and need cleaning. However, it could also occur due to a faulty power source, software bugs and if the temperature is too low or high, affecting the robot charging.
Sometimes, when the RoboVac battery is not positioned correctly, it can stop charging.
I understand how frustrating it can be for everyone; therefore, the easy fixes I have provided in this article will help you get your robot working again.
But before we jump into the troubleshooting tips, here are the common causes of charging problems in your robot vacuum.
Dirty Charging Metal Contact Points
Accumulated dust and dirt on the charging contacts of your robot vacuum can inhibit power transfer, preventing effective charging.
As a vacuum expert, I recommend regular cleaning of both your robot and its charger to maintain optimal charging efficiency.
Dead Battery or Charging Base
If either your robot’s battery or charger becomes defective, it will not charge. Over time, rechargeable batteries reach the end of their life cycle and require replacement.
Generally, replacing the batteries fixes the problem.
Faulty Power Source
Sometimes, if your robot isn’t charging, it could be due to a tripped power outlet. Test the outlet by using a different device or try another outlet.
Before exploring other troubleshooting methods, confirm that the outlet is functional and the charger is correctly plugged in.
Outdated Firmware
Charging issues with your robot vacuum could also result from outdated system software or other glitches. Therefore, keeping your Eufy Robovac updated with the latest software is essential to prevent such problems.
You can fix most of these issues yourself and won’t require a professional to help. So, I recommend using our troubleshooting tips provided later in this article before you contact Eufy customer support or hire a professional.
How To Fix Eufy Robovac Not Charging?
I know how frustrating it could be if your robot vacuum has stopped charging. Use the below solutions to fix your Eufy RoboVac charging problem.
Try Changing the Power Outlet
Generally, wall outlets wear out after years of use. The plugging and unplugging of cords loosen the connections, causing permanent damage to the outlet.
I do have one such outlet in my apartment that was causing this issue.
However, you can quickly fix this problem by trying other wall outlets and see if that works. In my case, it worked, and I had to fix the wall outlet that was not working.
When the charging base of your Robovac is correctly connected to a functional outlet, you will see a solid white indicator light, which shows that the connection is proper and power is being supplied appropriately.
However, if you notice that the indicator light on the base is either off or flickering despite being connected to a working outlet, the fault is with the charging station.
Clean the Eufy Robovac Metal Charging Contacts
Eufy Robovacs have two metal connectors on the bottom of the robot that act as charging pins. These connectors often accumulate dust and moisture that acts as an insulating barrier, disrupting the flow of electrical current from the charging station to the battery.
This results in the failure of your robot vacuum from charging and can stop your vacuum from working once the battery drains out fully.
To Resolve Charging Issues with Your Eufy RoboVac
- Prepare Your Cleaning Solution and Cloth: Grab a microfiber cloth and some isopropyl alcohol.
- Clean the Robot’s Metal Contacts: Dampen the microfiber cloth with the isopropyl alcohol and gently rub it over the two metal contacts on the underside of your Eufy RoboVac for approximately two minutes.
- Dry the Metal Contacts: After rubbing, use a clean, dry cloth to wipe the contacts, ensuring no residue is left behind.
- Clean the Charging Dock’s Contacts: Repeat the same cleaning and drying process for the metal contacts on the charging dock.
- Test the Charging Process: Once both sets of contacts are clean and dry, manually place your Eufy RoboVac onto the charging dock and check to see if it begins to charge.
After thoroughly cleaning the contacts, your robot vacuum will resume charging as expected. If not, exploring other potential solutions to rectify the issue may be necessary.
Ensure That the Robovac Is Aligned Correctly on The Charging Base
If your Eufy Robovac is not charging, it might be due to incorrect alignment on the docking station. This can prevent the charging contacts from making proper connections, inhibiting the charging process.
When you manually place your robot vacuum on the charging base, the charging contact plates may fail to sit and connect with each other, causing no charging issue on your RoboVac.
Therefore, when positioning your robot on the dock, it’s essential to ensure that the charging plates on the vacuum and the charging station align correctly.
If you see an orange light that appears to “breathe” or pulse on top of the robot, it’s charging. Once the battery is fully charged, the light color changes to blue. So, always check for these visual cues to confirm if your Robovac is charging as expected.
Power Cycle The Charging Base
You can try power cycling the base station if the above solution doesn’t work. This process will help you resolve any glitches with the Eufy charging station, allowing it to reset its configuration parameters or recover from a critical error, such as a system crash or freeze.
Simply unplug the base station from its power source and wait for 30 to 60 seconds. This will allow the device to discharge its residual power fully.
Now, plug your Robovac back into the charging station and check if your RoboVac has resumed charging.
Make Sure The Power Button On RoboVac Is ON
If you have been using RoboVac for quite some time, you would have observed that there’s a power button under your vacuum. This button is for switching OFF your robot vacuum when you are going to pack it for a long time.
Eufy’s official site suggests that if your Eufy Robovac is unresponsive or fails to connect to the charger,
Toggle the power switch six times and gently shake the robot to remove any dust or debris that might have built up over time.
Now, switch the power switch ON and put your robot on charge. If your vacuum starts charging normally, you have fixed the issue. Otherwise, follow the below troubleshooting steps.
Check For a Worn Out Battery
Generally, a Eufy RoboiVac battery lasts for around 2 years. Sometimes, the battery can get worn out before the time due to heavy usage.
But before you buy or replace a battery in your Eufy RoboVac, you should check for these signs.
- The Red light on RoboVac with 4 beeps when connected to the charging base.
