Is Your Shark Robot Vacuum Acting Up?

If you’ve wondered, “Why is my Shark Robot Vacuum not charging?” you’re not alone. When your vacuum doesn’t work, it can be annoying, but don’t worry—we’ve got you covered. This guide will demonstrate how to fix your Shark Robot Vacuum to work again.

Why Is My Shark Robot Vacuum Not Charging: Troubleshooting Guide

1. Turn on the Power Switch

Shark vacuums have a power switch, which sets them apart from most robotic vacuums. While you probably already know this, you may not know that the Shark can’t charge when the switch is off. 

Press the button to turn on the Shark Ion Vacuum and try charging again. Good luck with that. If that doesn’t work, we’ll explore other commonly used solutions.

2: Check if you need to place the vac manually.

A blue LED light should be on your Shark Robot Vacuum, indicating the battery charge level.

If at least one light is on, your robot may have enough battery life to return to the charger autonomously. The battery may be too low to return to the dock if all lights are off. 

In such cases, assist by replacing the vacuum to the dock and recharging it. Additionally, for the initial use of your robot vacuum, charging it in the dock before operating it is recommended.

3: Clean all charging contacts.

The Shark Cleaner has two metal points that should connect to the two metal plates on the charging dock. As long as these parts are in contact, the battery can charge.

However, connections sometimes work differently than expected. If this is the case, wash the connections on both the bot and the charging port.

Observe the battery lights to check if your vacuum is working; They will glow during the charging process.

4: Check the dock for power and proper operation.

Although unusual, a problem can cause the Charge Dock not to work correctly. Confirm dock readiness by checking for a green light next to the dock.

If the light is missing, make sure the dock is plugged in and use a different outlet.

Always place the dock in a location with clear space—five feet in front and three feet on each side. Insufficient space may prevent RoboVac from returning correctly.

5. Check the Charging Port Contact Springs

The vacuum’s charging ports connect to two metal pins on the charging dock, both held in place by springs. If these parts break, the vacuum will not connect.

If this happens, your Shark Ion Vacuum may not charge or link to the dock. Check the springs by pressing the metal pin with your finger.

You’ll need to acquire a new charging dock if they don’t snap back into place.

6. Check for Obstructions:

Ensure no obstructions or trash around the charging dock for your Shark robot vacuum. Small objects like pet hair can damage the vacuum’s ability to properly connect to the charging dock.

Check the charging dock and vacuum for any hardware issues that could stop the link from working. Clean the area, then place the vacuum on the dock.

7. Manually Dock Your Vacuum

Docking your Shark vacuum manually can be an easier option, especially when the battery is so depleted that the machine can’t even attempt to detect its dock.

Place the vacuum on the charger directly with the cover facing the dock so that the charge plates align correctly with the contacts.

Correct placement is about 1/2 inch from the vertical part of the dock on the front of the Shark.

Wait a few minutes for the Shark to realize it’s charging, especially if the battery is low. When this happens, the blue light will start flashing, indicating the end of your segment.

If the light is green, move the machine back into place. Before using it again, wait for the device to be fully charged. If the link drops too soon, restart the process.

8. Reconnect the Battery

To secure the battery to your Roomba, turn the vacuum over and open the battery cover between the roller brush and the charging cable.

Pull the wire as close to the battery as possible. Remove the cord from the vacuum and reconnect it, ensuring a tight connection to the port.

Finally, either press the dock button again or manually dock the vacuum.

9. Replace the Battery

Shark Ion cells typically last about two years with regular use. If you suspect your robot vacuum’s battery is dead, you may be trying to determine how much time has passed since your purchase.

When purchasing a new power pack, ensure compatibility with your Shark vacuum model.

This pack fits the Ecovacs N79 and N795 and the Shark RV700, RV720, RV750, and RV755. It also works with most other Shark robot vacuums.

After receiving the new battery, repeat the same steps used to test the old battery.

When removing the old one, replace it with the new one you purchased, and be sure to dispose of the dead battery properly, as it is a lithium-ion battery.

10. Reset Your Vacuum

11. Update Firmware

Outdated software can cause problems with how well things work. If there are any mods for your Shark robot vacuum, find and install them.

Manufacturers often release firmware changes to fix bugs and improve overall system performance.

12. Test with a Different Outlet:

If you want to rule out a problem with the port, try putting the charging dock in a different one. Outlets may only sometimes function properly or provide a constant power source.

Check if the Shark Robot Vacuum starts charging by plugging it into a known good outlet. If it does, the first plug may not work correctly, so don’t use it to charge anything else.

By carefully checking for possible obstructions, ensuring the power adapter is working, and trying a different outlet, you can troubleshoot common problems preventing your Shark robot vacuum from charging correctly.

If the problem persists, you may need to push further troubleshooting steps or contact Shark Customer Service for assistance.

13. Contact Shark Support

Before making any payments, contact Shark to inquire about insurance coverage for your vacuum repair or replacement. Have the ticket ready when they ask for it.

Although a free replacement is likely only if your vacuum is relatively new and well-maintained, it’s still worthwhile to call and explore the possibility.

Why Is My Shark Robot Vacuum Not Charging – Maintenance Tips

Maintenance is essential to ensure your Shark robot vacuum lasts as long as possible and works at its best, especially if you are experiencing charging issues. 

The critical step in this process is to clean the charging contacts properly. 

Regularly check the Vacuum and Dock charging contacts and clean them if necessary. Dust, soil, and trash can accumulate over time, preventing smooth power flow. 

For thorough cleaning, use a lint-free cloth soaked in rubbing alcohol. Reach the hard-to-reach areas precisely with a cotton swab dipped in alcohol. 

This extensive cleaning practice improves the charging process and protects against potential problems.

Ensuring a good charging position is equally important. In addition to cleaning, the location of your Vacuum charge plays an important role. 

Adequate airflow prevents the charging dock from overheating, and maintaining a clean area around it ensures smooth docking. 

Providing a stable power source and keeping the vacuum battery within the correct temperature range benefit its health. 

Considering these external factors as part of your regular care routine optimises the charging process and protects the Vacuum against potential problems, ensuring reliable and long-lasting performance. 

Remember that a well-maintained Vacuum is not only clean but also consistently efficient.
