If your Lefant robot vacuum is having problems, don’t worry – you’re not alone.

This comprehensive Lefant Robot Vacuum Troubleshooting guide will help you fix the most common problems and get your vacuum back up and running in no time.

Let’s get started.

Lefant Robot Vacuum Troubleshooting

Lefant Robot Vacuum Reset How To Do It

To reset your Lefant robot vacuum, turn on the side witch.

Now press and hold the key for about 3-4s until you hear a beep. Release the key.

The vacuum will enter network configuration mode and the blue light will start to blink.

The vacuum should be reset and ready to use.

Why Is My Lefant Robot Vacuum Beeping?

If you hear one beep three times, there probably is a problem with the driven wheel.

Check the wheel for any obstructions. If the wheel is clear, try resetting the vacuum (see above).

If you hear two beeps three times, it could mean there is something wrong with the side brush.

You want to make sure that the side brush is properly installed and not obstructed in any way.

If you hear three beeps three times, this indicates a problem with the motor.

Start by emptying the dust bin. Clean the filters, and if the problem persists, you may need to replace the motor.

Other issues that could lead to a beeping sound include an obstruction in the front wheel, a problem with the cliff sensors, or low battery.

If you can’t figure out the source of the beeping, try resetting the vacuum (see above).

Lefant Robot Vacuum Won’t Charge 

There are various reasons why your Lefant robot vacuum might not be charging.

They include the following, among others:

  • The Robot Is Not Switched On

This is among the most common reasons why your robot might fail to charge.

You need to make sure that the charging dock is turned on, and that the power cord is properly plugged in.

  • The Battery Is Damaged

If you’ve been using your Lefant robot vacuum for a while, it’s possible that the battery has reached the end of its lifespan and needs to be replaced.

  • The Charging Dock Is Damaged

If the charging dock is damaged, it will need to be replaced. Check for any obvious signs of damage, such as cracks or breaks.

  • The Power Cord Is Damaged

If the power cord is damaged, it will need to be replaced. Check for any obvious signs of damage, such as frayed wires or a broken plug.

  • The Robot Isn’t Connected to The Charging Dock

Check and ensure you have correctly placed the robot on the charging dock.

The charging contacts on the bottom of the robot should be properly aligned with the contacts on the dock.

  • There Is an Issue with The Power Adapter

Some of the issues with the power adapter include a loose connection or a damaged power cord. Check the connections and ensure they are secure. If the power cord is damaged, it will need to be replaced.

  • There is a problem with your power supply

Check to see if there is power through the outlet you are using.

If not, check your fuse box or circuit breaker. If there is power to the outlet, try plugging in another device to see if it works.

  • Internal Electrical Issues

If all of the above troubleshooting steps fail, it is possible that there are internal electrical issues with your Lefant robot vacuum.

In this case, it will need to be sent in for repairs.

How Do I Know If My Lefant Vacuum Is Charging? 

There will be a glowing red light on the charging dock when the vacuum is charging.

If there is no red light, check the power cord and ensure it is plugged in.

Also, make sure the charging dock is turned on. If there is still no red light, try resetting the vacuum.

What Is The Initial Recharge Time For Lefant Vacuum?

It takes about three-and-half hours to fully charge a Lefant robot vacuum.

However, over time, this may vary depending on factors like the age of the battery and whether or not it is completely depleted.

Lefant Robot Vacuum Battery Replacements

Lefant recommends that you only use batteries that are specifically designed for their vacuums.

These can be purchased from the Lefant website or authorized retailers.

Lefant Robot Vacuum Blinking Red Light 

When the robot vacuum is blinking red, it means there is a problem with the device.

The flashing red light is often accompanied by a beeping sound.

Refer to the problems/solutions to beeping sound discussed above. If the beeping persists, it is best to contact customer support.

Lefant Robot Vacuum Purple Light

While it depends on the model of vacuum, generally, a purple light means that the battery is charging. Once it is done charging, the light will turn green.

It could also mean the robot is entering the pairing mode.

In this case, the manual will have instructions on how to connect the vacuum to your phone or another device.

Lefant Robot Vacuum Cleaner Not Turning On

There are a few reasons why your vacuum might not turn on. Check to see if it is plugged in. If it is, check the power cord to see if there are any signs of damage.

If the cord appears to be damaged, it will need to be replaced.

If the cord is not damaged, try resetting the vacuum. To do this, press and hold the power button for about three seconds.

If the vacuum still does not turn on, try charging it for at least three hours. If it still does not turn on after being charged, there may be internal electrical issues and you will need to contact customer support.

My Lefant Robot Vacuum Is Stuck

If your Lefant robot vacuum is stuck, first check to see if there are any obstructions. If there are, remove them and restart the vacuum.

The brushes could also be tangled.

To fix this, you will need to remove the brushes and clean them. Be sure to follow the instructions in the user manual so that you do not damage the vacuum.

If the vacuum is still stuck, try resetting it.

If that does not work, there may be an issue with the sensors and you will need to contact customer support.

My Lefant Vacuum Won’t Dock

The first thing to check is the charging dock.

Make sure that it is plugged in and that there are no loose wires. If everything appears to be fine with the dock, try resetting the vacuum.

If the vacuum still will not dock, look for any obstruction below or around the dock. If something is blocking it, move it and try again.

If you’ve tried all of these things and the vacuum still will not dock, there may be an issue with the sensors or wheels.

It is always advisable to contact support if you suspect there is an internal issue that you cannot handle.

My Lefant Robot Vacuum Doesn’t Clean the Whole Area

There may be small obstructions in the way of the vacuum.

Check to see if there are any small objects on the floor that you can clean by hand before starting the vacuum.

Another reason could be that the brushes are not spinning. This can happen if they become tangled with something.

To fix this, you will need to remove the brushes and clean them. Be sure to follow the instructions in the user manual so that you do not damage the vacuum.

The Robot Can’t Clean Automatically

There are three main reasons why this may happen. The first is if the robot is turned off. Check to make sure that the power button is in the ON position.

The second reason could be that the battery is low. If the battery is low, the robot will not be able to clean automatically. Try charging it for at least three hours to see if that makes a difference.

Lastly, there could be an internal error caused by, say, parts being entangled by debris. If this is the case, you may want to clean the robot, following the user’s manual instructions.

Final Thoughts- Lefant Robot Vacuum Troubleshooting
