Why is my Roomba not charging | How to troubleshoot and fix!

Roomba not charging

If your Roomba refuses to charge, clean the charging ports with rubbing alcohol and a soft cloth to remove any dust or hair.

It’s also possible that you’ll need to reinstall or replace your battery or charging dock, or even reset the Roomba to factory settings.

Make sure the electrical contact points are free of debris.

Because the Roomba is a vacuum cleaner, it may collect dust and grime, causing it to get unclean and malfunction.

Electric connections, for example, are known to cause an oxide layer to form on the charging port or to collect dust.

This is why, in order to prevent errors that might limit the Roomba’s lifetime, it must be cleaned.

The greatest aspect is that you don’t need to hire a professional to clean your Roomba. All you’ll need are a few basic cleaning supplies from around the home.

Use a soft, dry cloth and some 99 percent isopropyl (rubbing) alcohol to clean the contact locations.

Cleaning the charging points with a microfiber cloth or melamine foam is also an option.

You’ll have to troubleshoot if cleaning does not alleviate the charge issue.

Why isn’t my Roomba charging?

Your Roomba is an electrical gadget that may malfunction for a variety of reasons.

The following are the reasons why your Roomba battery isn’t charging.

  • The battery is out of date.
  • Electrical contacts have been clogged.
  • The Charger Plug Is Faulty
  • Home Base isn’t working properly.
  • Pull tab for yellow battery
  • Dusty Caster Wheels
  1. The battery has reached the end of its useful life.

Any electrical device’s original battery has a shelf life, and your Roomba’s Lithium-Ion battery is no different. It’s possible that the battery is dead or malfunctioning.

  1. The electrical contacts are clogged.

Because your Roomba is a vacuum cleaner, it may grow unclean, and the electrical connections connecting the Roomba to the Home Base may clog. The Roomba would be unable to charge adequately as a result of this.

  1. The Charger Plug Is Faulty

When the charger plug is defective, energy cannot transfer from the power outlet to the charger (wall socket or otherwise). As a consequence, no power is sent to the Home Base, which means your Roomba will not be charged.

  1. There is a problem with Home Base.

The Roomba may not be able to determine where the Home Base is after it has been cleaned if it has a malfunctioning Home Base. Even if the docking station isn’t sending energy to the Roomba, you can still charge it.

  1. Pull tab for the yellow battery

If your Roomba is brand new, make sure the yellow pull tab at the bottom has been removed. This is used to separate the battery from the robot’s power supply, preventing it from functioning while on the shelf by mistake.

  1. Dusty Caster Wheels

Check for debris accumulation on the caster wheels, which might prevent the Roomba from completely attaching the charging connections to the Home Base.

How to troubleshoot Roomba battery not charging

If your Roomba battery unit isn’t charging, here’s how to diagnose and repair it.

  1. Turn the Roomba back on.

Rather than the hardware, the problem is often with the program. It’s possible that a problem will prevent the Roomba from indicating that it’s charging.

The first step is to do a soft reset. The Roomba will resume, but the factory default settings will not be restored.

Deep charging or 16-hour resetting are other terms for battery reset.

Because your gadget would have to be placed to sleep for 16 hours.

To reset the Roomba 600 series battery, follow these steps:

  • Remove the battery from its case.
  • Press and hold the clean and dock buttons on the device.
  • Release the buttons whenever you hear a beep from it.
  • The Roomba should start up and show the charging indication when you plug it back in.
  • Then charge it for 16 hours, or until the green indicator light illuminates.
  • The 700 and 800 series Roombas, on the other hand, include a separate reset button. Holding it down for 10 seconds will gently reset it.

To reset the Roomba 700 series battery, follow these steps:

Connect the Roomba to the power source.

Hold the “Clean” button down until you see the blue letters “r 5 t” on the screen.

Allow the machine to shut down automatically and listen for the reset tone.

Then, for a total of 16 hours, charge it.

Charge your Roomba machine directly to the power source, ideally using the home base cable, for optimal benefits.

  1. Switch to a new power source.

Before getting into comprehensive cleaning and more difficult troubleshooting solutions, it’s a good idea to double-check our wiring and sockets.

When you plug the Home Base into a socket, the power light should illuminate.

The GFCI outlet has most certainly tripped if you don’t see the light.

While plugging in, switch to a different power outlet and double-check the connections.

  1. Make sure the docking station is clean.

It’s possible that the Roomba won’t charge if it doesn’t receive enough electricity.

One of the most prevalent reasons is a build-up of dirt on the charging connections. The link between the ports and the output has been broken.

Cleaning the docking station for debris on a regular basis is recommended. It could be just what you’re looking for.

Here’s how you can do it:

  • Flip the Roomba over to remove it from the caster wheel.
  • Ensure that the wheels are clear of any debris.
  • Using rubbing alcohol and delicate cloth, clean the charging contacts.
  1. Replace the battery

During transportation or for any other cause, the battery may be displaced or loosened from its original position.

Before changing the battery or claiming the warranty, be sure it’s in the appropriate spot.

To get access to the battery compartment, remove five screws on the back panel, then replace the battery in the right spot.

Replace the screws and plug in the Roomba after that.

  1. Draw the battery pull tab out.

I’m assuming your Roomba is brand new.

You may not have remembered to remove the battery pull tab.

Yellow pull-tabs may be seen on the batteries of most modern gadgets.

Manufacturers apply it to prevent devices from turning on by themselves, particularly while shipping.

This tab prevents the battery from making contact with the contacts.

So, if you haven’t done so yet… Your smartphone will thereafter be unable to charge.

If this is your first Roomba, remove the pull tab by following these steps:

Invert the Roomba vacuum cleaner.

Keep an eye out for the hanging pull tab.

Then completely rip it off.

After you’ve removed your device, it should charge normally.

  1. Move the gadget to another room.

It’s uncommon, but your Roomba won’t charge if the room is too hot or cold.

Like any other device, your Roomba and its Home Base should be maintained at room temperature.

If the engine is exposed to temperatures that are too hot or too cold, it may not be able to perform properly.

If this occurs, your Roomba will show an error code on the screen until the issue is resolved.

Only by placing your device in a room with a reasonable temperature will you be able to prevent this.

Note: Allow it to rest for at least an hour before charging it back on its Home Base.

  1. Reset the machine to factory settings.

If restarting the unit’s software or battery doesn’t solve the issue, the device must be factory reset.

Factory resetting, unlike restarting, erases all of your data and settings.

This covers your cleaning regimen as well as the layout of your house.

To put it another way, it restores your smartphone to its original factory settings.

Make a backup of your data if you’re convinced you to want to factory reset your device.

There are two ways to factory reset your Roomba. Using either the iRobot Home app or the device directly.

Factory reset Roomba using the iRobot Home App:

  • Go to the iRobot Home App page.
  • From the menu, choose “Settings.”
  • Select “Remove/Factory Reset” from the drop-down menu.
  • Then, on the robot name of your unit, click.

Take note of your Roomba series before doing a factory reset.

Here’s how to factory reset your Roomba based on the Roomba series:

The series A and I,

Press and hold the “Home,” “Spot Clean,” and “Clean” buttons at the same time. Hold your breath until you see the light ring become white.

The J-series

First, remove the garbage from the unit. Then press and hold the “Clean” button for 7 seconds. Let go after you hear the reset tone. To complete, click the “Clean” button.


Press and hold the “Home,” “Spot Clean,” and “Clean” buttons at the same time. Hold it for around 20 seconds. Then relax.

The 900-series

Press and hold the “Dock,” “Spot Clean,” and “Clean” buttons at the same time. Hold the button down until all of the button’s indicator lights turn on.

The 600 and 800 series are Wi-Fi enabled.

Press and hold the “Dock,” “Spot Clean,” and “Clean” buttons at the same time. Maintain your finger on the button until a beep tone is heard.

Combination Roomba

By opening the device lid, look for the “Reset” button. For roughly 10 seconds, press and hold the reset button.

Is it possible to change the battery in a Roomba?

Yes, of course!

There are several Roomba battery replacement choices available nowadays. However, not all batteries are created equal, and some might actually degrade the life of your device.

One thing is certain: if properly maintained, the original battery will endure many cycles before having to be replaced.

The following is a list of battery care guidelines to help you understand how to prolong the life of your Roomba’s battery and guarantee that it always operates at its best:

  • Use only iRobot batteries.
  • Because the Roomba is powered by a rechargeable battery, it will run over longer periods of time if you use it regularly.
  • When not in use, keep Roomba plugged in – if you don’t have a Home Base, you may connect Roomba into the charger to keep it charged at all times.
  • Charge the device and keep it in a cool, dry location.
  • To keep the gadget from being blocked with hair or debris, clean it regularly.
  • If you sense a strain when operating your Roomba, check it right away. Allow it to rest if you don’t want the battery to drain quicker.

Roomba Troubleshooting and Repair FAQs

  1. What is the best way to tell whether my Roomba is charging?

Check to check whether your Roomba is charging by looking at the LED light indication surrounding the CLEAN button. Colors to look for include:

Solid Red – The battery is either fully charged or is in the process of being fully charged.

The battery is charging while the amber light flashes.

Fully charged – solid green

The Roomba is in the midst of a 16-hour charging cycle, so it’s pulsing amber.

  1. What is the battery life of a Roomba?

The battery should last 400 recharges, or 2 to 4 years, depending on the size of your house and how often you use the Roomba.

If you live in a tiny home or don’t use your Roomba much, you may prolong the battery’s life. Replacement batteries are, however, readily accessible and reasonably priced.

  1. Does the light on the Roomba charging port remain on while it is charging?

The charging station light does not remain on while the Roomba is being charged. The light will flash for around 5 seconds before going off to save electricity.

  1. How can I tell if the battery in my Roomba is dead?

The power light on your Roomba will be a solid green color when it is completely charged.

You’ll see a pulsing amber color while it’s still charging.

When the battery is running low, the light will flash red, and when the battery is completely exhausted, the light will be solid red.

Because this vacuum cleaner’s battery is rechargeable, you may keep it charged by buying and installing an optional charging station called the Home Base.

  1. Can Roomba be used without a base?

Roomba can operate without the need for a home base. The home base serves as a charging station as well as a secure storage location after the cleaning is completed. Your Roomba, on the other hand, will operate just fine without the home base.

It will charge, clean, and do other tasks as needed, but it may not be as handy as having a home base.

Because the Roomba offers two charging choices, this is the case.

Most Roomba vacuums come with a charger on one end that connects into your Roomba and a power source on the other end.

If you start it manually, it will return to where it started after cleaning if it doesn’t have a home base. So, sure, your Roomba can function without a home base.

Final Thoughts

A malfunction in your Roomba unit, like as filthy electrical connections or an outdated battery, might cause it to stop charging.

To keep the electrical connections clean, dust the charging ports with rubbing alcohol. If the battery is outdated, just replace it and your Roomba will charge normally.
