Roomba Charging Error 5: Total Solution Is Here

I’ve been struggling with Roomba charging 5 error for the last few days, but haven’t found a solution yet. I tried several guidelines from various troubleshooting forums to solve this problem.

They have provided much general information and no technical data that they might have obtained by measurements.


I tried there provided suggestions like changing the battery pack, changing the power supply, resetting by pushing the spot and dock button for several seconds, plugging into the Roomba directly not thru home base, and also tried cleaning, pulling the metal thing under the battery for battery contact issue; but nothing has worked for me.

This is the condition. When I plugged it into the transformer, charging faster light blinking started in a systematic way. But half an hour it had comes up “ERR5”, or “Charging error 5”, and the Roomba’s troubleshooting light blinks 5 times.

Don’t kick out your Roomba or throw it across the home like a flying disc. Before you freak out don’t worry, this can be fixed! There is enough data for you to identify the failed component.

Therefore, those who would like to save time and don’t want to give effort behind the faulty device, can purchase a robot vacuum for dog hair, this can be a great relief for a household with pets.

Charging Errors

1 Blink or Charging Error One

1 Blink error message means the battery is not connected yet. You will probably need to unscrew the battery cover and check to see if anything is obstructing the battery contact points. Check to confirm the battery is placed correctly and the yellow battery pull tab has been removed. You might need to scrape the contacts with a knife to really get the crud/carbon off so the metal can make proper contact.


2 Blinks or Charging Error Two

This “charging error 2” means your Roomba has charging error and it may need to cool at least one hour. The Roomba will also need to fully charged in an AC environment to make sure it doesn’t overheat once again.

3 Blinks or Charging Error Three

This error says that the Roomba has a charging error, which can be solved by resetting it and recharging it.

5 Blinks or Charging Error Five

This “Roomba has a charging error” message can be solved in many ways. One way is to remove the pull tab fully from the vacuum and also by resetting the Roomba and charging it fully until the clean light turns green.


6 Blinks or Charging Error Six

When you see this charging error, it means that the Roomba battery has overheated. This can be solved by letting it charge in an AC environment or by letting it cool off for about one hour.

7 Blinks or Charging Error Seven

The seventh charging error you will see says that the battery on the Roomba is not properly cooling off. If you let the vacuum charge in a cooler environment and let it cool off for an hour and it still overheats, it is likely faulty and will need to be replaced.

8 Blinks or Charging Error Eight

The Roomba is unable to create contact with the Lithium-Ion battery. The battery may be damaged or just need replacement. 

9 Blinks or Charging Error Nine

Similar to Charging Error 8, and the same solution the Lithium-Ion battery may need replacement.

  1. I have an old 540 that I bought for my Mom. She used like twice and put on a closet. Years later she wants to use. Wouldn’t charge or turn on. Bought a new battery. Acts like it is charging with normal amber slow flashing light. Turned green but took off charger and won’t do anything. Now it will charges for a while then blink the red error. Once off charger nothing. Help

  2. I have a 530 I Robot and the green light on the charger lights up but nothing happens on the machine, I’ve replaced the battery and still nothing, tried to reset machine and still nothing, where do I go from here, thanks
