Shark Ion Robot Troubleshooting - Error and Blinking Codes - Vacuum Cleaner (1)

Shark Ion Robot Troubleshooting: Blinking and Error Codes

All LEDs are off

If there is no light, the device may be off. Or maybe the battery is dead, so it needs to be charged.

Try turning the switch on and off and if there are no responses, place it on the charging base. Your problem will be solved.

RED LED is on

This can also be called Replace LED. This indicates a notification about the battery when it is ready to be replaced.

Most of the time when the battery is damaged or used for a long time. As a result, the consumption of the battery decreases, which limits the capacity of the battery and needs to be replaced.

Parpadeo DOCK y SPOT

OS dock and spot can flash together or alternately. If they flash together, you should know that the side brush is clogged.

Maybe there is debris or dust clogged in there. Just remove them from the side brushes and it will stop flashing.

If DOCK and SPOT flash alternately, then there is an obstacle in the brush roll. Take any semi-sharp tool and remove the destruction. The flickering will be fixed instantly.

To note, be careful when removing obstacles so as not to damage the machine.

flashing BLUE

A clean flashing blue indicates an error in the ION drop sensor, front wheel sensor, or fender. Now, you might be wondering why this should happen.

It is quite common for your device to get stuck with other things. If the wheels can't move freely to different places, it produces a clean blue flash.

Make sure that the bumper and wheels do not get caught in any way and that the device can move freely. The problem is sometimes due to the wheel cavity. Better check it well and clean it carefully.

Flashing BLUE DOT

The absolute reason behind this is that the device cannot move due to some kind of obstruction. Two arrangements can be made,

Firstly, you can give your device a mobile surface, so you don't face this problem, and secondly, you can move your device to a new location where there will be no interruption.

CLEAN flashing RED

Clean red flashes are an indication of cliff sensor errors.

Since your device has a full-time dust service, it is quite possible that you will have clogging problems from dirt and dust. You may have problems like shark robot vacuum not picking up dirt.

Every time dust accumulates on the cliff sensor, the red LED starts flashing.

The solution is simple. Take a tissue, soft cloth, or paper towel and wipe the drop sensor until no dust is visible. Once this is done, your ION vacuum will work properly again.

🇺🇸 flashing symbol

This indicates a suction motor failure. Blockages in the filter can easily become this problem.

Just clean the filter properly. Make sure there is not too much dust inside, it will work fine again.

🇧🇷 remains Solid and CLEAN RED Blinking

This can be seen when your device's charger is experiencing issues. In continuous use or in adverse conditions, the charger loses its voltage delivery capacity.

The wire itself is not as capable of carrying voltage as it once was.

This is the correct situation where you may encounter the message “! stays Solid and LIGHT RED flashes.”

It is best to contact Shark® Customer Service as soon as possible for assistance with the charger.


Simply when you remove the recycle bin, the Clean Solid Red prompt begins. Put it back in place and you're done.

RED ! and the blinking red Wi-Fi indicator

This means that the entered password is not correct. Make sure of the password and try again.

If you have tried multiple times, wait 30 seconds and try again.

🇧🇷 Wi-Fi indicator red and flashing red

This means that your ION robot does not have a wireless connection. The connection you are dedicating yourself to using is not available.

So connect some other devices to make sure the network. Then try again with the ion robot.

🇧🇷 and the Wi-Fi indicator flashing alternately

This means that you entered the wrong username or password for your Shark account.

Enter the correct one again and you're done.

A few words for internet connection problems,

  • Your Shark ION robot only connects to 2.4 GHz networks.
  • Restarting your Wi-Fi router can improve the connection as the cache is automatically cleared with a fresh start.
  • Rebooting the phone can also help in the same way because continued use can lead to (minor) errors and lag in the system.
  • And finally, to fix the anonymous Wi-Fi connection problem, you can restart your Shark ION Robot. After a long period of use, this can be very useful. And the machine will surely start again.

Irregular movements are the result of

dirty sensors

You need to know that your robot cleaner works automatically, moving to different areas of your room using sensor detections.

Again, the device has to cope with a large amount of dust in your apartment.

It's very easy to clog some dust above the sensor eye, which can cause jerky movement of your device.

Easily fix it by wiping the eye of the sensor with a paper towel, tissue, or cloth.

dirty wheels

This can be defined as a common type of interrupt. Hair, cotton, and outdated ribbons often get caught in the wheel. This interferes with the free movement of the wheels.

Try to inspect where the obstacles are stuck. Then carefully remove them without damaging your device.

engine problem

Once you notice that your robot is having trouble moving, try checking it out on different types of surfaces, such as carpets or the floor.

If you encounter problems with your device on any type of surface, then the motor has a problem.

You should probably inform your nearest customer service and have the motor replaced.

proper fit

Often the device does not dock properly because there is some interruption between the base and the robot. As a result, the upload does not start.

Power source

If your power source cannot provide sufficient power flow, it is normal for charging to stop.

In this situation, please try to change the outlet or take appropriate measures to achieve stable power flow.


In prolonged use, the contraction of battery juice is a common problem. And when the battery capacity decreases, charging problems occur from time to time.

In this case, replacing the battery is the best recommendation.

Shark Ion Robot is unstable

Damaged battery

Maybe the battery of the device is damaged, that's why the robot stops every few minutes.

The battery is so degraded that it cannot provide enough power for a long time. As a result, after a certain period, the device suddenly stops.

The only way to resolve this is to replace the battery with genuine customer service.

clogged brush

In addition to the problem of the stuck wheel, the main problem here is the ribbons, cotton or hair lying on the floor. What happens is that these things just roll on their axles.

When this material gets caught up in the main brush and day after day it builds up in a clump that prevents your ION robot from moving properly.

Take some tweezers and clear all the obstacles from the main brush, and the robot will work fine.

How to reset the Shark Ion robot vacuum

  • Turn your ION robot over. You will find the power switch.
  • Hold down the switch for 10 seconds. (Hold down until the device turns off)
  • Wait another 10 seconds and press the button again. The device will reboot and the reset will be complete.

In the end, most of these issues are easy to fix with the simplest steps we've included. But sometimes the problem with the Shark® Robot ION Vacuum can be related to the internal hardware.

What's worse is that you can't solve complex hardware problems yourself unless you are an expert.

Therefore, it is better to contact authentic customer support and get expert support and compatible replacement support.
