My Roomba Won’t Charge

Your Roomba might not continue to charge after being plugged in overnight for a number of different reasons. This is frequently due to dirty charging connections on the Roomba, however your Roomba’s battery may also be at fault. It’s possible that the problem is where the car’s charging station is located.

Roombas and other robotic vacuums are useful in any home since they can clean your floors without further assistance from you. Their best attribute is their capacity for independence. Once you’ve first put them up, you may leave them alone and they will keep working for a very long time.

Your Roomba can recognise when the battery is getting low and dock at the charging station right away. However, if something goes wrong, you can return home to a dead Roomba.

In this post, we’ll examine a few probable problems and show you how to fix them so that your Roomba can start charging again.

My Roomba Won’t Charge

Charging Contacts Are Dirty

Charging Contacts Are Dirty Both the charging station and the Roomba have connectors for charging devices that can transfer electricity from the charging station to the Roomba.

The Roomba can only be charged while it is in touch with the strips of the charging station. Two very tiny metal strips that resemble contact points make up the charging connectors.

Why It Fails:

Dirt might accumulate over time on the charging station’s and Roomba’s contact points. The Roomba can’t charge if this occurs since the contact points won’t be able to connect completely.

The Roomba’s contact points, which are located close to the front of the device where the brushes are, are more susceptible to experience this. Consequently, the areas where the parts come into contact with dust and dirt often.

How To Fix It:

However, it is simple to clean the contact points on your Roomba and its charging station. A Roomba won’t charge frequently because the charging connections are filthy. If your Roomba won’t charge, you should try this first.

Your contact points may be cleaned in a few different ways.

  • If using a dry towel to clean it doesn’t work, you might also try using rubbing alcohol and a moist cloth.
  • If neither of these solutions work, you could get better results using a sponge made of steel wool.

Make careful to unplug the charging station from the outlet before cleaning the contact points. Avoid accidentally shocking yourself with electricity.

Faulty Roomba Battery

Of course, the battery is the component of your Roomba that actually stores a charge and supplies the suction power. Particularly rechargeable Ni-MH (nickel metal hydride) batteries are used in Roombas.

The Roomba’s battery should be able to maintain a charge for roughly two hours and should last for about 400 charging cycles, according to manufacturer iRobot.

Why It Fails:

Your Roomba’s battery, of course, is the component that actually maintains a charge and powers the vacuum. In particular, Roombas employ rechargeable Ni-MH (nickel metal hydride) batteries.

According to iRobot, the manufacturer of the Roomba, the battery should be able to retain a charge for around two hours and endure for 400 charging cycles.

How To Fix It:

You’ll need to buy a new battery for your Roomba if the current one is entirely dead. The good news is that iRobot makes getting a new battery simple, and changing the battery itself is not difficult.

  • First, remove the five screws holding the bottom cover on your Roomba’s base in order to change the battery. The lid is secured by four of these screws, and the rotating brush is secured by the final one.
  • You may now pull off the lid to access the battery after removing the screws. The battery is held in place by two tabs. By releasing these tabs, you may remove the battery from its slot.
  • The issue should be resolved when you instal the new battery and reassemble your Roomba.

To keep the battery in good condition, keep your Roomba in a cool, dry location when not in use. Additionally, you must routinely clean your Roomba’s brushes. Your Roomba’s battery will last longer if you use it frequently.

Faulty Charging Station

Naturally, your Roomba can only recharge itself using the charging station that is included with it. Although you may charge your Roomba without it, the station is necessary for automatic charging to function.

Why It Fails:

A Roomba’s charging station doesn’t often malfunction on its own. The possibility that the contact points on the charging station are filthy has previously been discussed, but it is also possible that the charging station isn’t receiving electricity from the wall socket.

How To Fix It:

To start with, you should determine if the Roomba, the charging station, or the outlet the station is hooked into is the issue.

  • Your GFCI outlet may have tripped, or the charging station may have triggered the circuit breaker for that outlet, if you have one.
  • Additionally, confirm that the charging station’s connector is fully inserted into the outlet.
  • One additional test you may perform is to put the Roomba’s charging cord straight into the outlet if you already know the outlet is not the issue.
  • If the battery indicator on your Roomba illuminates when you do this, your charging station is probably the issue.
  • You’ll probably need to get a new charging station from iRobot if the current one is definitely dead.
  • You could be eligible for a free replacement if your Roomba is still covered under warranty.

Dirty Caster Wheel

The small wheel near the front of your Roomba is the caster wheel. This wheel isn’t powered and can’t be used to steer. Its only job is to keep the Roomba at the right height.

Why It Fails:

Over time, things can get stuck in the wheel well of the caster. If there is enough junk in there, it can push the wheel out of its housing more than usual.

Since the caster wheel is close to the charging contacts, this basically lifts the Roomba so that the charging contacts on the Roomba can’t touch the ones on the charging station.

How To Fix It:

The caster wheel of a Roomba is fairly simple to remove and clean once it has been dirty. You just need to grip the stem that connects the caster wheel to the Roomba firmly and pull it out to remove it. The stem is what holds the caster wheel to the Roomba.

The caster wheel well may be accessed once the wheel has been removed from the caster. After you have removed any debris that you discover in there and reattached the wheel, your Roomba should begin operating as it did before.

Temperature Error

Your Roomba won’t operate if the battery is too warm or too cold. You will get an error code if your Roomba shut down due to the temperature. Codes 6 and 7 indicate if the battery is too warm or too cold.

How To Fix It:

  • Move your Roomba to a cooler location and leave it there for at least an hour if it is giving you a temperature code problem.
  • This should be all you need to do if temperature extremes are what’s truly causing the issue.
  • Consider shifting your charging station to a warmer area of your house if at all possible.
