Why does my Roomba not charge?

If your Roomba 650 still does not work properly after the reset and does not charge even though it is connected to its Base Station, either the Base Station contacts or the Roomba contacts may be dirty, preventing power from being transmitted.

So the very first thing to do is to clean the contacts. It can happen that during a cleaning cycle dust and dirt accumulate at these places and thus prevent the current transmission and thus the charging of the battery.

When cleaning, however, remember that your Roomba 650 is an electronic device and that you do not work with too much water. It is best if you use a slightly damp cloth and wipe off the contacts so that they are clean again.

For coarser dirt, it is usually enough to just walk your finger over it and clean the contacts with your finger. When cleaning the contacts, make sure that the charging station current is not plugged in.

How can I extend the life of my Roomba battery?

All batteries have a limited lifespan. Roomba batteries usually last two to five years, depending on how you care for them. If it does get to be scrap at some point, it’s not a death sentence for your Roomba – you can simply buy and install a new Roomba 650 battery*.

But to delay battery replacement as long as possible to save money, here are the most important points on how to extend the life of your Roomba battery.

Use your Roomba regularly

This may seem a bit paradoxical at first glance, but the batteries of Roomba vacuum robots like to be used frequently. Normally you would think that frequent use would wear them out, but in fact it’s like a workout.

It is therefore recommended to run a Roomba every day or every other day and to drive back to the charging station every time it finishes its work.

Keep your Roomba clean

The less the Roomba has to work while cleaning, the easier it is for its battery. This means that you should remove items that interfere with its mechanics, such as hair or carpet lint.

When long hairs knot around its rollers and accumulate, it becomes more and more difficult for it to drive. This puts unnecessary strain on the battery and reduces its running time. The best thing is to dismantle and clean the brushes once a week.

If you have pets or there are many long-haired people in your household, you may have to do this more often. It would still be perfect if you took the entire device apart about once a month and cleaned it of dirt and dust.

Vacation Mode

If you are not at home for a long time, you should fully charge your Roomba first and then store it with the battery removed in a dark and cool place. The removed battery is the most important thing, the cold and dark storage is only an optimization.

Roomba batteries do not like it when they are discharged. You can avoid this with this vacation mode.

Once you have returned from your holiday, you can reassemble your vacuum robot and plug it on the charging station until the battery is fully charged again. Your Roomba 650 can then resume its normal work.

Keep the Roomba battery cool

This tip applies to almost all batteries. If you let your vacuum robot work in a cool environment and, above all, charge it in a cool place, you will increase its service life.

Direct sunlight not only damages the exterior, but also increases the temperature inside and thus the battery. So, when you place the charging station, make sure it is in a rather cold place in your home and protected from the sunlight.

Of course, you should also make sure that a heater is not installed directly next to its home base.

Execute a “Deep Charge” on a regular basis

The manufacturer iRobot recommends regularly subjecting the battery to a deep charge procedure. This intense charge is sometimes called a 16-hour reset.

Just like the other methods listed here, a deep charge increases the battery life and runtime.

To execute the deep charge or 16-hour reset, you need to do the following:

Take out the battery.
Press and hold the Power button for at least 5 seconds.
Put the battery back in.
Charge your Roomba for at least 16 hours. The best way to do this is to plug the power plug directly into the Roomba and not use the charger. After the 16 hours, the green lamp should light up.
Keep your Roomba running until the battery is completely empty.

This procedure should have improved its battery life. If this is not the case, your battery may need to be replaced*.

Replace old Roomba battery with new lithium battery

There are now also for older models of Roomba lithium batteries that last much longer than the standard nickel based batteries from iRobot.

To take a closer look, you can click here*.

Lithium-ion batteries have become the standard for most electronic devices such as smartphones and laptops. In contrast to their old predecessors, these new batteries have 1.5 times the capacity and running time.

But what stands out most is the extension of the battery life itself. Lithium batteries do not discharge automatically and have no memory effect.

Where old iRobot batteries can withstand about 400 charge cycles in normal use, lithium batteries can still have more than 80% of their original capacity after 800 cycles!

So you can quickly figure out that a lithium battery pays off quickly. Not only do they have a very good price-performance ratio, but they are also fully compatible with the Roomba and the charging station.

Attention: When installing electronic equipment, please be sure to observe the manufacturer’s safety instructions. You have to take care of your own safety. The information on this site only helps you to learn.
