How To Fix iRobot Roomba Charging Issue?

The charging issue of the Roomba robot cleaner can be fixed easily. Let’s have a look at the various solutions for charging your iRobot Roomba i7 or other models.

1. Clean the Contact Sensors Gently

Roomba Charging Sensors

If your iRobot Roomba i7 or other model is not charging when plugged in, you should inspect the contact sensors or charger and your Roomba vacuum cleaner.

When you flip your Roomba cleaner, you’ll see two metal contact sensors that attach to the sensors of the charger.

Check if any dust layer formed on the contact sensor, and clean it deeply with a soft cloth and rubbing alcohol.

Roomba recommends cleaning it with the wipes provided by the company but a gentle clean with isopropyl alcohol will do the job.

Don’t forget to clean the contact sensors of the charger too otherwise your Roomba won’t charge.

2. Press and Release the Charger Sensors

The contact sensors of the Roomba charger are tightened on a spring system. When your Roomba robot attaches, an upward force will be applied so that both sensors make tight contact with your Roomba.

Sometimes the spring is stuck and it won’t apply upward force on the Roomba charging sensors due to this, it won’t make proper contact between the charger and Roomba.

You can press and release the charging sensors so that spring action is restored and your iRobot Roomba starts charging again.

If it doesn’t work, you need to replace your Roomba charging base.

3. Replace Your Power Adapter

Sometimes problems lie with the power adapter and we keep inspecting our device. If you’ve tried the above solutions, you should check your power adapter.

If there is no light glow on the charger, it means your power adapter is faulty and it needs to be replaced.

You can buy a new iRobot Roomba charger from Amazon at a cheaper price or buy it from the company website.

4. Replace Your Roomba Battery

If you’ve replaced your Roomba charging base but it still won’t charge then check your battery.

If you noticed that your Roomba battery life is decreased drastically, it means it’s time to replace it.

You can buy a new Roomba battery replacement from Amazon or the company website. If your device is still under warranty, register a complaint on Roomba customer care and they’ll replace the battery at no cost.

Pro Tip: If you’re not going to use your iRobot Roomba for a few days/week (leaving for a vacation), it’s better to remove your battery to save it from the idle drain. It improves the overall battery health.

Follow these steps:

  • Press the CLEAN button to turn ON iRobot Roomba.
  • Press and hold the SPOT and DOCK buttons together for 10 seconds.

After two hours, you’ll see that the CLEAN button is turned Green. Now, your Roomba will not cause any issue in charging or battery backup.
