It needs to recharge every time it docks.

I would suggest that you let Roomba run out of the room where it's charger is. Then force it to run until it dies out. Then put it back onto it's charger.. I suspect that it's developed a memory (short) for charging and you need to force it to totally drain down, then charge for a good while. This should force it to develop a "Longer" memory. Works for me anyway.

SOURCE: My Roomba does not want to dock

Need more info.
Does the unit go into search mode? "SPOT & CLEAN" flashing? It actually tries to search?
Do you have another roomba to test your dock on to see if IT will dock? If it tries but just cant, then either the dock transmitter, or the roombas receiver is dead. (The round antennae thingys on the dock and the bumper) replace these would be the first point.

SOURCE: roomba 530 just keeps on circling and can't dock

Your bump sensors are malfunctioning. I had the same problem. The best thing to do is order a repair kit. I ordered mine from EESolutions.ca and it worked great. I'd recommend it.

Roomba undocks and then immediately redocks


I don't know much of anything about roombas, but that sounds to me as though the battery is not holding a charge. Check the voltage to see if it is normal. If not, I would replace the battery.

Roomba Schleduler Charging


Bad battery most likely. Could be a faulty charger too. Have your local vac shop test it.

I roomba wont dock


That's usually caused by a charging issue. Could be that the contacts the roomba uses to charge on the base are bad or the contacts on the roomba its self. Here is a good troubleshooting guide. Roomba customer service is very good too, if the roomba is less than a year old they will repair it for you. good luck!

My roomba 530 cleans just great, but it will not return to the docking station--it just stops in the middle of the floor without any warning. I push the dock button, etc. to no avail.


I sometimes have the same problem with my Roomba 530 (named Ethel). Make sure the signal transmittor on the docking station and the signal receiver on the top of the Roomba are clean. You can use a cloth or paper towel with a SMALL amount of window cleaner to run around both of these signal devices. I also like to clean the metal contacts on the station and the corresponding contacts on the bottom of the Roomba at the same time. This won't make a difference for the docking but it just assures that the vacuum will charge efficiently. If this doesn't work, you might need to have the unit cleaned professionally unless you feel comfortable about taking the unit apart and cleaning it yourself. I did this and Ethel has worked fine ever since!
If this helps, please come back and rate my suggestion!

My roomba 560 approaches the dock and attempts to dock. However, it never seems to align correctly and backs out. This is a continuous process. It simply will not dock at all. Any suggestions?


Check the connector on your ROOMBA, there is a switch that open the ground when you connect the charger direct to the ROOMBA and a lot of times it get stock and remain open. Using a small screwdriver press the metal plates to force to close.

4210 and 4230 won't charge-new batteries.


I've been having the same problem myself. The charger is apparently built into the roomba main board. From what I've read there are two MOSFETs U2 & U4 that can go out and require replacement to fix the problem. More info here

My Roomba 560 does not automatically dock as advertised either..


You may not believe this, but the new 500 series lighthouse virtual walls have both infrared and radio frequency communication. How they work and associate with the Roomba is pretty complicated. The best posting I've ever seen about how they work is here:
http://www.robotreviews.com/chat/viewtopic.php?f=1&t=11048

Check out that link to understand how the communication works.

If your Roomba is contained by the virtual walls, then you can assume the IR sensor on your Roomba us good....you should test that though. Then you might have to replace the "home base" which could have a bad IR transponder . New ones can be found for reasonable price at www.RoboticVacParts.com or you could order straight from iRobot for twice the price.

If the Roomba is not contained by the virtual walls, then the IR sensor on the Roomba is likely bad and you'll need to change the bumper on your Roomba. Again ....parts are available through ebay, or www.RoboticVacParts.com. Follow this link if you need it.

Roomba Docking Station


Probably not, unless you just have to have the docking station. My roomba always had trouble mating with my docking station so I never used it. I just plugged it directly in to will using the AC adapter.
