Have you noticed lately that your Roomba 650 is playing up?

It could be that it’s battery is not lasting as long as it normally would on a complete charge. Or the battery might be taking longer than usual to fully charge.

There might be a variety of reasons that are causing this to happen but if you want a free and simple way to solve these issues, I am going to show you how to reset your Roomba 650.

Before I start I should warn you that after following these steps, you will need to set the time, date and schedule again on your machine.

How to Reset a Roomba 650

This a simple 7 step procedure.


  1. Remove the Roomba vacuum from it’s charge base.
  2. You have to turn on your Roomba 650 by pressing the “clean” button.
  3. Press and hold the “Spot” and “Dock” buttons (that are placed above and below the “clean” button) for ten seconds. 
  4. Release both buttons at the same time and you will hear the sound of your Roomba starting up
  5. Now place your Roomba 650 back in it’s charging station until the green light surrounding the “clean” button is lit.
  6. Your Roomba is ready to go.
  7. Now set the time, date and schedule again

Hopefully resetting your Roomba will solve any performance issues that you might have.

But if your problems continue and you think they might be battery related, it could be that you need to take better care of your vacuum’s battery.

How can I maximize my Roomba battery life?

Replacing your Roomba battery will cost you at about $20.

You can avoid that or at least delay it by maximizing the one that came with your iRobot Roomba.

Here are my top four tips

  1. Clean Your Vacuum Regularly

Each time you use your Roomba, things like dust and dirt are attached to it. The Roomba has to work harder to clean up your room, and this requires more energy from the device.

As a result, the battery drains faster. So at least, remove the brushes once a week and get them cleaned. If you have pets or messy children clean it more often than that!

And, once a month or so, just inspect the whole machine and at least give it a wipe over to to keep it as “good as new”.

If you spot more stubborn stains or marks on it, do your best to clean them off.

  1. Minimal Charging

Don’t leave your Roomba on charge constantly! Some experts believe that this will shorten the life of the battery.

Try and get into the habit of turning your charging station off when the battery is at 100%- the green light around the “Clean” button glows green.

A full charge might take up to 12 hours. Charging your Roomba for days could damage its battery. Although of course they are other experts that believe that constantly charging a battery does not shorten its life span.

  1. Regular Use

Another way to keep your robot vacuum’s battery in the best possible shape is to make sure that you use it regularly.

Some people believe that the batteries that power modern gadgets such as laptops, smart phones and vacuum cleaners are like human muscles.

The batteries need to be used regularly (discharged) and then recharged regularly in order to keep their strength up.

  1. Vacation Mode.

This is closely related to point 2.

If you are going away on vacation, charge your Roomba battery completely then remove it from the device. To do that, flip the Roomba over, unscrew the battery door, and remove the battery.

Then when you get back from your trip, recharge the battery until full, then run it until it dies and goes back to your regular routine.

Eventually, you will have to replace the Roomba 650 battery, but with all these tips, you should be able to put off that expense for a while.

Don’t forget to read the Roomba 650 user manual and follow the instructions in it.

This will ensure that not just the battery but the device as a whole last longer.

Why Does My Roomba Not Charge?

You might notice that your vacuum cleaner is not charging when you fix it to the dock.

You have checked and double checked that the dock itself is turned on.

The most common reason for this fault is that the contacts on the battery are dirty or that the contacts within the dock are dirty.

And so the solution is simple- clean the contacts.

Before you do anything else to be safe, unplug the dock.

In order to clean them, you will need to use a damp cloth.

Also, make sure that;

  • you use a soft cloth that hasn’t got a rough surface that could damage or mark the battery contacts
  • that the cloth is damp and not dripping with water. Do not any cleaning fluid.
  • Use enough pressure with the cloth to make sure that it gets rid of any visible dirt or any other substance that might be stuck to them.

Once the contacts look clean, make sure that you dry them with another soft cloth that won’t leave any fluff or debris on the contacts.

Plug the dock in and place the Roomba 650 back into it.

Hopefully, after cleaning the battery contacts, your Roomba is now charging.
