Eufy Robovac 11s Stops Working Suddenly

Eufy Robovac 11s Stops Working Suddenly

This is a very common problem that a lot of people face. When your Robovac stops working, a number of reasons can be responsible for that.

In most cases, it happens when there’s something wrong with the battery. If you use your Robovac regularly, the battery will slowly lose its capacity day by day, which can affect the performance of your machine. So if the battery is running low, your device will stop working suddenly.

Sometimes though, if your machine is stuck with any obstacles like stones, debris, or flits, it can have problems functioning properly.


Now that we know the causes, solutions can be made very easily.

  • If the battery is running low, then you have to charge your Robovac to its full capacity before working with it. And if the battery is damaged, then you will have to find a replacement for that.
  • Then, check if there’s any obstacle inside the machine. You will also need to check the wheels and the axle.
  • If you find anything, remove it and clean the machine properly. You can use a brush to reach the small spots, or you can also use a toothpick with isopropyl alcohol.
  • In rare cases, if the problem still persists, then you will need to force-run your machine. To do that, simply turn the device off and wait for 2 seconds. Then turn it back on.

And this should solve the problem.

If the Robovac isn’t activated, it won’t be working effectively to clean your house. Mostly, this problem arises if the batteries of the remote have issues, or the device isn’t fully charged.

  • Then, you have to replace the batteries of the remote control, making sure that the remote is within the range of 5 meters.

Your Robovac might not be able to get charged if it’s not getting a proper power supply. Or it may also happen due to dirty charging contact pins. If your Robovac is not charging, it won’t be able to work to clean your house.


  • To solve this, you need to check if the indicator of the charging base is lit up. If it’s not, then you’ll have to repair the charging base or ask for a replacement, by contacting the Eufy service center.
  • Then, clean the charging contact pins. With a dry cloth, just dust off the excess dirt.
  • Make sure that the Robovac is getting an adequate power supply. You will need to connect the power cable of the Robovac to the power source properly.

It happens mainly when the filter is wet or dirty. Also, when the suction inlet is blocked, suction may become weak.

  • If the problem still doesn’t go away, then try replacing the filter. Check if the suction becomes any stronger than before.
  • Lastly, check if the filters are wet. If they are, then you’ll need to Air-Dry them before using them.

Eufy Robovac 11s Rolling Brush Is Not Able To Rotate

The main reason for this happening is excess dirt and dust accumulation in the rolling brush. If the rolling brush can’t rotate, the Robovac 11s will not be able to pick up dirt from anywhere.
