Your Shark robot vacuum won’t charge doesn’t mean it’s dead. Some minor issue can also stop your vacuum robot from charging.

Your Shark robot will automatically locate the charging dock and align with the charging sensors.

But, if it won’t locate the charging dock or not charging even after locating, try these solutions:

Shark Robot Vacuum Sensors

There are several proximity sensors and infrared lights are located on the front of Shark vacuum robot. These sensors guide the robot to locate the charging dock.

Due to continuous use and untidiness, a dust layer forms on the sensors and it won’t function properly and can’t locate the charging dock.

Remove the front plastic cover and inspect the sensors. If you notice any dust buildup on the proximity sensors clean them with soft microfibre cloth.

3. Clean Your Charging Dock

4. Clean the Charging Sensors

Clean Both Sensors

If you flip your Shark robot, you’ll find two metal piece located at the bottom. These metal pieces are charging sensors that connect with your charging dock.

Flip over your robot and thoroughly clean the charging sensors with rubbing alcohol and micro fibre cloth.

5. Align Your Robot Properly

The two charging sensors of your charging dock connect with your Shark robot vacuum cleaner.

Due to regular use, wear and tear occurs on the charging dock and robot. Once it reaches to the charging dock, it won’t align properly.
