If your Roomba still won’t charge after being parked for some time, the battery may be faulty.

It’s also possible that some of the components within the Roomba cleaner aren’t operating properly.

Regardless, it may take some time to tackle these difficulties since you may need to treat each one independently before locating the one that requires resolution.

And while you’re here, I’ll go over all of the possible reasons with “Why wont my Roomba charge“, as well as the troubleshooting procedures you’ll need to do to fix it.

Clean off the Charging Contact

The charging connections (metal strips) that link the charging station and the Roomba vacuum cleaner allow electricity to be transferred from the charging station to the Roomba vacuum cleaner.

Even if the metal strips are correctly linked, they may not charge.

Why is this the case? Dirt specks are one of the reasons they aren’t connecting when nothing is in the way.

These occur as a result of repeated use, which causes dirt to accumulate on these connections, preventing the battery from maintaining complete contact with the contact points.

If you encounter this, I will explain what you must do to detect and address it.

Fixing it:

If your Roomba isn’t charging, one of the reasons “Why won’t my Roomba charge?” is a consequence of unclean charging ports.

Clean the contact points with a dry towel.

  • If that doesn’t work, use a wet cloth with a little alcohol.
  • If the dirt is really difficult, try a steel-wool sponge.
