Roomba troubleshooting roomba irobot 700 series wont work?


What sort of light do you see when you correctly place it onto it's charger? Green light is what you want to see. Otherwise it doesn't have a charge. I would check to see if it needs a cleaning.

If you're sure the battery contacts are clean and the battery really is charged, then there is faulty circuitry within the Roomba that would have to be repaired or replaced.

Confirm that the battery is inserted with the metal contacts down so they make contact with the spring terminals in the battery compartment.

Visually confirm that the metal contact plates on the battery pack, and the spring terminals in the battery compartment are clean and shiny. If not, wipe with a clean cloth or paper towel, its OK to use a little water or rubbing alcohol on the cloth, if needed, and then dry it.

Visually confirm that the metal contact plates on the Roomba, and the spring terminals on the docking station's home plate are clean and shiny. If not, wipe with a clean cloth or paper towel, its OK to use a little water or rubbing alcohol on the cloth, if needed, and then dry it.

If you have a volmeter, measure the voltage between the contacts on the battery pack If it isn't something in the neighborhood of 14 volts and is 11 volts or less, the battery isn't fully charged.

Reinstall the battery.

For the moment, please connect the power adapter directly to the Roomba rather than the docking station to eliminate one possible faultly connection.

If the battery wasn't fully charged, or you weren't able to test it, try to charge the Roomba and then retest the battery voltage if you can. If the battery voltage was higher immediately after charging, but didn't get to 14 volts, the charger is good, but battery needs to be replaced. If the battery voltage was unchanged after attempting to charge the Roomba, the charging circuitry may be faulty. If there was no light patterns when you tried to charge it, and it was plugged in to a good outlet, then the power adapter or charging circuitry is definitely bad.

If you have no voltmeter and you cleaned the contacts and tried to charge the Roomba and it works, use the Roomba and then recharge using the docking station and see if it was just dirty contacts or it won't charge through the docking station. If it didn't work, you'll need to figure out if its the battery, the charging circuitry in the Roomba, or the power adapter. If there are no lights when you try to charge the Roomba, then Either the power adapter or the Roomba power circuitry is defective, but without a voltmeter you can't find out which one, and there's no way to know if the battery is good or bad, but you know Roomba wasn't trying to charge it. If there are lights when you try to charge the Roomba, then at least you know the power adapter is good. Unfortunately, without being able to test something there's no way to distinguish between a charger that won't deliver a charge to the battery and a battery that won't accept a charge. If you want to take a guess then a bad battery is more common and less expensive to fix.

My roomba 530 runs in a circle and does not move forward. After 2 minutes it stops with 11 beeps and a flashing red light to the left of the power button. It has no clicking noise. Does anyone know what is...


Hey'
This means Roomba is not registering obstacles. Roomba may be stuck in one place.
Roomba may be in extremely large room, try setting up virtual walls to create smaller area.
If Roomba is not in a large room, tap Roomba's bumper to confirm it is properly working.


Hope this helps

Light flashes but won't turn on


The Roomba's internal charging system is not working. In this situation, a replacement Roomba is necessary. You can call 1-877-855-8593 to find out what your options are. There's a discount for Roomba owners who need replacement units.

Roomba 560, the small red light above the schedule button will not reset and the roomba will not run. The problem started when I the roomba sat dead for 12 hours. I tried the spot dock reset trick with no...


You should start by removing the "belly plate" of the Roomba and simply removing the battery to cycle power to the unit. If that does not solve the problem, it sounds like you need a replacement circuit board for the 560. That's alot trickier since iRobot doesn't like to sell those...they want you to send to them for service.
Your options would be to send to a reputable Roomba repair center like www.protechrobotics.com or you can buy a replacement PCA from places like www.RoboticVacParts.com and replace yourself.
