Roomba stops running after 2 minutes

The roomba is fully charged wtih a new battery and will run slowly for 2 minutes or less and then quits. I cleaned the white and black wheel and the sensor below it. I cleaned the entire machine also and the filter.

    Roomba is clean and seems fully charged.  Runs fine for about ten minutes and stops

  • zaaga13 Mar 05, 2009

    Roomba runs for ten minutes and then the red light goes on, and it stops dead.  No amber warning light of an almost -spent battery. Just green to red and dead stop.

First drain the battery completely and then take out battery and charger and hold power button for 30 seconds and then clean the roomba with compressed air take out all compartments and blow air thoroughly everywhere especially near the wheels where the wheel sensors are. Leave battery to charge for full day and try to run.

My Roomba Model 440 runs for about 2 minutes and stops. I can start it up again after which it repeats stopping after not quite 2 minutes. It is perfectly clean and charged. What is the problem?


Most likely your NiCad battery is at the end of it's life and needs replacement. The packs in Roombas are made up of a group of individual cells and what often happens as they age is that a single cell will fail, causing the entire pack to provide less than usable voltage. The Roomba will attempt to operate and then sensing low voltage, it will shut down.

To prevent reduced battery life in the future with your new pack, always keep your Roomba charged as storing a NiCad pack in a discharged state will cause the build up of salts within the pack, damaging the cells.

Replacement is simple and packs are around $40 bucks online, all you need is a small Phillips screwdriver and about 5 minutes.

Fully charged, runs 2 minutes and stops


You have dead nimh (nickle metal hydride) batteries2_bing.gif.
You will need a replacement. You can test for this by removing the battery and holding the power button for 15 seconds. This will restart the charging cycle as if the battery were new. Try Ebay for better pricing.

I have a Roomba, it runs for a few minutes and stops, the battery is fully charged. Any ideas?


The battery isn't able to fully charge, it just retains the proper voltage, but lacks the amperage to run because the first and last battery in the pack are dead. Battery replacement time. Try Ebay for best battery pricing.
BTW I use the nicad pack.

This is a roomba 560. First started acting crazy, ''even ''singing'' on the base. No no power at all, no clean botton light at all, the base turns green when you put it in there like charging ... The...


Something is blocking the battery current and preventing the Roomba from running.

Low voltage contacts can be blocked by thin films formed by condensible organic outgassing in the home environmental (That's the yellowy haze that slowly builds up on the wall paint.)

Try cleaning the battery contacts with a little rubbing alcohol or contact cleaner on a foam swab, or a bit of paper towel. Take a litle time, it doesn't always dissolve instantly. (Don't use a pink pencil eraser, it would scrub off the plating that prevents corrosion) Clean both contacts on the battery pack and both of the contacts in the Roomba. Make sure the battery is oriented correctly when you put it back in.

If that doesn't help, the battery itself can be defective such that it has a very high internal resistance and can only charge and discharge very slowly. It can be fully charged, and unable to deliver that charge at a pace that allows the Roomba to operate. Sometimes its possible to rehabilitate such a battery by conditioning it over several charge and discharge cycles, and sometimes its ineffective. Since thr Roomba won't run you'd have to use a something like a 20 to 50 ohm power resistor to drain the pack to 10v before charging it.

Of course as your description suggests, its also possible the processor has a fault and you need to buy a new one.

Roomba cuts off after a minute or so.


If you have a 400 series Roomba, try removing the battery, then holding down the power button for ten seconds, then recharging the unit before you run it again.

If you have a 500 series Roomba, don't take out the battery-- just press and hold the "spot" and "dock" buttons for about fifteen seconds. The Roomba will play a tune, and you can then charge it and try running it again later.

Scooba not working after full recharge


NiCD and LiOn batteries have this tendency. They work great for a year, then slowly die off. The problem is you. When new, the device MUST be charged for 14hr nonstop, then every 2-3 months run dead, and recharged again 14hrs nonstop. This is done so the CPU of the Roomba (cool toy) KNOWS what DEAD is and what FULL is. It does this by measuring the amount of currrent flowing thru a very precise resistance. If you do hit and miss charge cycles of the roomba or leave it charging too long, it either develops a flase memory of the above two conditions, or gets HOT and the electrolyte paste dries out. Fix is to wear it out, charge 14hrs, wer it out againand repeat 3-4x. Then recharge and use. If that doesn't fix it, the batteries are too dried and need to be replaced.

Roomba 4200 Scheduler


The best for the battery if (NiMH). Discharge completly, than charge full (charge more even the charger indicates full charge)

Clean every part, maybe a hair slow down the wheels and thats why need more power.

Here some tip from the web:


With proper care, one iRobot Roomba battery can last for hundreds of cleaning cycles before you need to replace it. Here are some things you can do to extend Roomba's battery life and keep Roomba cleaning at peak performance:



Use your Roomba frequently. Your Roomba is powered by a rechargeable nickel metal hydride (NiMH) battery, which lasts the longest when you use it regularly.



Keep the brushes clean. If the brushes and brush axles get clogged with hair and other debris, your Roomba will strain to spin them, using more battery power than normal. In extreme cases, the battery can even be damaged. See How to remove and clean Roomba's brushes



Keep your Roomba plugged in when not in use. If you have a Home Base®, keep your Roomba docked in the Home Base and plugged into the charging brick. If you don’t have a Home Base, keep your Roomba plugged into the APS Fast Charger.



Make sure you are charging your Roomba correctly. When your Roomba is plugged in correctly, the solid green light should be illuminated on the charger or on the Home Base.



Plug your Roomba in as soon as possible after using Max Mode. Leaving your Roomba unplugged for more than 24 hours can damage the battery.



Place your Roomba and the Home Base on a smooth, hard surface when yourRoomba is plugged in. Make sure your Roomba and the Home Base have plenty of space for ventilation. Do not charge your Roomba on a carpet or rug.



Charge and store your Roomba in a cool, dry place. Keep your Roomba out of direct sunlight and away from sources of heat such as windows, radiators, heating vents, and large appliances.



Remove the battery when not using your Roomba for a long period of time. If you will not be using your Roomba for more than a few weeks, fully charge the battery, remove it, and store it in a cool, dry place. When you want to use your Roomba again, insert the battery and fully charge it. Leaving your Roomba plugged in for weeks when it is not being used can damage the battery.

You can purchase a second battery or replacement online at the iRobot Store.
