After a busy day at work, you're looking forward to coming home to a newly swept floor, courtesy of your Shark® robot vacuum. But instead of a spotless hallway, you're greeted by a blinking vacuum sitting sheepishly in the middle of the rug. Why is my Shark robot vacuum not charging, you wonder?

Asurion Experts fix issues like this every day. From explaining how robot vacuums work to detailing the best smart home essentials, count on us for guidance you can trust. Here's what to do when your Shark robot vacuum is not charging.

Why your Shark robot vacuum won't charge

If your Shark vacuum is not charging, it's probably because of one of these issues:

• No power: If the power switch is turned off, the Shark vacuum can't charge.
• Dirty contacts: Shark robots collect a lot of dirt, which can cover the charging sensors.
• Improper dock placement: Charging works best when the dock sits flat on the ground.
• Temporary glitch: A random software glitch can interfere with charging.
• Loose or worn-out battery: A Shark robot vacuum will not charge if its battery is depleted or displaced.

The vacuum's indicator lights can hint at what might be wrong. But since the color and meaning vary by model, you'll want to check your user manual for details.

How to fix a Shark robot vacuum that's won't charge

When your Shark robot vacuum is not charging, Asurion recommends these troubleshooting steps.

1. Check the power switch and outlet

Shark robot vacuums usually have a power switch on their side. Make sure it's flipped on, and that you've securely plugged the cord and dock into a working outlet. The dock indicator will light up if everything's good to go.

If the outlet is controlled by a light switch, try moving it to a different outlet. Someone flipping the light off or on could unknowingly disrupt charging.

2. Clean the charging contacts and sensors

If a Shark vacuum is not charging on the dock, the contacts may be dirty. Use a dry, lint-free cloth to remove any grime from the robot and the dock. For stubborn grease, a small dab of rubbing alcohol on a cotton swab works. Just be sure to let things dry completely before re-docking the vacuum.

3. Move the dock to a better spot

Is your Shark dock sitting on the carpet or in a cluttered spot? Try putting it on a flat floor free of any nearby cords. Push it against the wall, and make sure it's not baking in direct sunlight.

Once you're okay with its location, reseat the vacuum in the dock and give it a few hours to charge. You can check its charging status in your SharkClean® app. But if your robot vacuum won't connect to Wi-Fi because of a dead battery, you may need to wait a few minutes for updates.

4. Restart the robot

A restart clears technical glitches that may lead to your Shark Robot not charging on the dock. To perform one, turn the power switch off and wait for at least 10 seconds. Turn it back on and place the robot vacuum back on its dock.

Shark occasionally releases firmware updates for its robot vacuums. Use the SharkClean app to make sure you have the latest version.

5. Check the battery

Moving from room to room can shake up your vacuum robot's internal components, including its battery. To make sure it hasn't come loose, open the battery compartment. You may need to remove a few screws if it doesn't have a detachable cover. Verify the battery is firmly seated, then close the compartment.

Unfortunately, robot vacuum batteries don't last forever. If you continue to have problems with charging, or the battery cuts off after minimal use, it may be time for a Shark robot vacuum battery replacement.

That's where having protection for your home tech comes in handy. The right plan will cover repairs or replacements, so you have somewhere to turn when things break down.
