Reason 1: Power Supply Problems

A faulty power source might potentially cause Charging Error 2. If the power supply does not deliver the right voltage or is damaged, the Roomba may not charge correctly.

Reason 2: Battery Issues

A damaged or aging battery might cause Charging Error 2. The Roomba can have trouble charging if the battery is unable to maintain a charge or appropriately communicate its charging status.

Reason 3: Dirty Charging Contacts

The Roomba’s charging connections and the docks may get clogged with dust, dirt, and debris over time. This accumulation may prevent the proper electrical connection required for charging to occur.

 How To Fix Roomba Charging Error 2?

Here are some of the effective yet simple troubleshooting steps to get rid of your Roomba error notification on its display;

Step 1: Always Use Original Batteries

The use of non-original batteries causes the majority of battery errors. iRobot always recommends that its customers use official and authentic Lithium-Ion Batteries. 

As a result of the incompatibility of local batteries and the defects they cause, it impairs their functional performance.

Always utilize genuine Roomba parts, batteries, and other accessories. Local or counterfeit batteries may function briefly, but the Roomba will eventually cease detecting non-original batteries and refuse to charge.

Step 2: Check the Power Source

Sometimes the power source of electrical equipment is the main cause of the error, and by fixing this problem, Roomba charging error 2 automatically resolves.

Here’s how you can do so;

  1. Conduct a visual inspection of the power supply for any damage or loose connections.
  2. Verify that the power cord or cable is connected to the charging dock and the power receptacle.
  3. Use a genuine Roomba power supply to avoid compatibility issues.
  4. Verify the functionality of the power supply using another device.

Step 3: Clean Battery Charging Stations

The Roomba battery is installed on the rear of your device and is secured with multiple fasteners at each corner.

  1. Initially, use a screwdriver to unscrew all of the fasteners.
  2. Now. Remove the Roomba device’s rear covering.
  3. Remove the battery with care.
  4. The battery is somewhat difficult to remove, so take care not to damage it.
  5. Wipe its exterior surfaces with a clean cloth.
  6. Tighten all of the fasteners and replace the device’s cover.

Step 4: Restart Roomba

Mostly a simple restart is enough if the problem continues on electrical equipment. It can fix minor problems with the Roomba, so follow the steps to do so.

  1. Press the “CLEAN” button for approximately 10 seconds on the Roomba.
  2. Release the button when a tone is heard.
  3. This reset can assist in resolving transient software or communication problems.

Step 5: Remove The The Hurdles

Always inspect the Roomba’s rear cover and battery for obstructions, such as hair or grime particulates, whenever the cover and battery are opened. In reality, they obstruct the connection area and do not transmit electricity.

When purchasing a Roomba for the first time, you may not have yet removed the yellow cover that is inserted inside; this must be done for the vacuum to function.

Step 6: Install The Battery The Proper Way

You may not have seated the battery properly if you attempted the above-mentioned techniques and opened your Roomba device before closing its lid and tightening the screws.

  1. Always secure all fasteners to prevent the cover from becoming open.
  2. Ensure that battery terminals are in contact with the metal contacts on the Roomba.
  3. Verify that no blocking object is within it.

Step 7: Resetting the Battery 

Resetting the battery is the last step when all simple troubleshooting steps don’t work. Follow the steps below to do a battery reset on Roomba:

  1. Use the user manual’s instructions to remove the Roomba battery.
  2. Remove the battery and press and hold the Roomba’s power button for 10 seconds to drain any remaining power.
  3. Reconnect the Roomba’s battery.

Place the Roomba on the docking station and let it charge for at least 72 hours; in some cases, this prolonged charging period may reset the battery and fix charging difficulties.

Step 8: Contact Support Services

It is recommended to contact Roomba customer care if the charging problem still occurs after trying the aforementioned methods. They may give further advice, offer more detailed solutions, or set up a repair or replacement if required.

Make sure to have the following ready for quick service:

  1. Your robot is charged and present.
  2. The serial number for your robot.
  3. A receipt of purchase (receipt or invoice for purchase from any authorized retailer) is required for warranty claims.
