Roomba has metallic charging points which are contacted perfectly with its charging station to charge Roomba. But, there may be some dust particles that block the connection and don’t let Charging Dock charge the battery efficiently. So, Clean metallic Contact Points.

  • First, take a clean cloth that you use to wipe your smartphone’s screen. This is the most effective way of cleaning.
  • Now, use your finger and clean the whole surface of the charging contacts.
  • If you are done cleaning the surface, put back Roomba on the charger and check if It stops giving the error and if it is charging correctly. 
  • Now, you are good to go.

Clean Charging points of Battery

Roomba battery is fitted on the back side of your device and it is tightened with multiple screws on each corner of the device.

Clean the Roomba wheels

You might be thinking What Roomba wheel has to do with its charging?

Roomba wheels alignment is in accordance with its charging station. If there are dust particles or hair stuck on the wheel, it will alter the height which changes the position of Roomba’s charging points and they don’t make contact with Doc metal points.


I) Clean Side Wheels:

First of all, look at the middle hole of your side wheel where you can have access to the axle of your Roomba wheel and remove all the debris with the help of a cloth. Detail steps are mentioned in the latter point.

  • Remove any hair or debris from the wheel.
  • Now, re-install the wheel into the housing ensuring that both sides of the axle snap firmly into place.

  • Re-install the caster wheel assembly into Robot.

Check the charging cable

Your Roomba power hub/base is connected to the power outlet via a charging cable. Most of the electrical devices in our home stop functioning just due to bad cable which may be faulty or burnt due to a short circuit. 

If it is burnt or faulty, replace it, connect it to the charging base firmly and charge again your Roomba.

Check Charging Station Power

  • Unplug the charging station and leave it unplugged for 2 minutes.
  • Plug the charging station back in and then check if the light will turn on.
  • The location of the light may vary based on the model.
  • Ensure that the outlet has power when plugged into the Dock.

Roomba Dock Spring Loaded Pads

They are attached under the contact points of your power base(Charging station). Sometimes, they get loose and get unclean. 

So, they don’t make the connection with the Roomba which causes the battery not to be detected by Roomba. Even if they are not in the right position, Roomba does not detect the battery.

A few drops of WD-40 or isopropyl alcohol will clean the contact points if they are unclean otherwise, you have to change the points or spring breaks inside.

Roomba battery has a life span of 2-4 years or 400 cleaning cycles after which it has to be replaced to make Roomba work again.
