SOURCE: 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.

SOURCE: my roomba 400 series keeps stopping on its own

Take off the grill on the back of the bin. The round vacuum impeller is behind it. Make sure that's clean and free of debris. Run the Roomba with that little grill still off the bin-- is the impeller turning? If yes, you may have fixed it. If not, your Roomba needs a new vacuum bin.

SOURCE: turns in circles, acts like it hits a virtual wall then stops

Reboot is probably not your solution. Your Roomba will react to invisible signals or 'interference' from other electrical appliances as well as the invisible wall boxes. You can clearly see how this happens when a Roomba gets near your computer or other device that is on. Also, the Roomba will go in circles when the dirt chamber is full or it thinks it's full. Try a thorough clean of all major parts including the brushes. Sometimes this activity will occur when the brushes get snarled on thread or carpet fibers.

Your manuals are here. Flashing lights must be covered. A quick look at the site says flashing red is bin full. In fact, I found it. Flashing Amber is CHARGING.

My roomba 550 goes round and round going know where.all the rest work ok


I have the complete service manual for the 550 series. It is in PDF format and if you would like the complete manual, give me your email address and I will send it to you. Below is the basic cause and repair for your irobot's condition.
Circling at slow, normal or rapid speed:
Most common causes: Dirt has infiltrated the wheel encoder or a drive belt has failed.
In MOST cases, the robot's software will recognize and correct the behavior within minutes. If the battery was recently reset, the robot may act erratic again at startup until the software has a chance to correct the condition. • If the Robot does not resume normal driving behavior within the first couple minutes of runtime, go to DRIVE WHEEL Module inspection and cleaning (Appendix C). If cleaning wheel modules does not correct the problem, both wheel modules may need to be replaced. • Replace drive wheel modules if fixes fail.

Roomba red #4100 needs repair does the circle


sounds like you have two different issues here. (Possibly one common)
Clean out the cliff sensors. Under the bumper. blow it out clean. This might stop the reverse circling. The battery is either bad, or the charging circuit is bad. if battery is know good then the problem is the main board needs to be replaced. a bad battery will kill a main boards charging circuit by over working it with shorted batteries

Roomba going in circles


Roomba going in circles. Called irobot and if reseting it (by taking out the battery, unplugging it from the charger, and holding down the power button for 30 seconds), didn't work, turn the roomba over, take a compressor and blow air into the front. Maybe a shop vac would also work. We cleaned out the whole thing while we were at it. And now it works just fine. The tech person at irobot was very helpful.

Roomba just runs in small circles


i just recently had someone bring in a roomba discovery and all it would do is stay in a tight 4 tile area and go in circles. battery was fully charged and all bumpers were clear.

i took a can of air blast for cleaning computers and blasted the area on the bottom underneath the sensor and watched as several dust bunnies came flying out.gave it a few more blasts for good measure and put it back on the floor and hit power then clean buttons.

thing went in same tight circle for 2 passes then the circle got bigger for 2 more passes , blue light indicator came on and it made a straight line dash across to closed door and started following the edge and criss-crossing the room.

called the owner back in to test and it repeated the same moves when she started it and all appeared to be working normal again.
