I believe the flashing red charge light is normal. When I first received my roomba and plugged it in, I got a flashing red power light. The next morning it had switched to the regular pulsing charge light. That night it was green, and roomba has been working a treat since.


Sorry, Ryan, I've had 3 Roombas. None of which flash the charge light. The tech support documents at Roomba.com also agree that a flashing light is a sign of a problem. Glad that it worked out for you, though, and thanks for your comment.

My mom gave me her old Roomba Discovery and said that if I could figure out what was wrong with it, I could keep it. The problem was that there was a flashing red light when it charged, and it would not keep a charge. I now know what I need to do to fix it. Thanks!


Well I wish mine had worked but the first time I pluged the darn thing it I got the red flashing light and to date have owned the stupid thing for 3 years and still not goten it to sweep my floor once. Finaly thought of going on line to find out why the red flahsing light wich isnt in the book was happening. There tech help sight was no help and Wife bought it through HSN and had not kept the papers from the purchas so I just threw the darn thing in a closet. Thank you for your idea maybe I can make it work would be nice. Thanks

What roomba battery model are you using with the rapid charger described above. I want to make sure it will work properly with our unit. Thanks.

Have another read. The second paragraph says I'm using a Roomba Discovery.

Our roomba will not hold a charge all of a sudden. It is plugged in all the time. It works about 5 minutes then dies. We looked on line and it was suggested to take the battery out, and hold the power button for 30 seconds, replace the battery and charge for 72 hours. WE did this and it blinked red for about an hour then went green.Not sure if it will work


Ms. Tatum's post was very helpful. My roomba had the same problem. Ms. Tatums solution seems to have worked.

I will try Ms. Tatum's suggestion. I have the same problem and REFUSE to contact Roomba or HSN - both were horrible experiences after I first purchased the Roomba and things were breaking immediately = (
For such a wonderful concept, the quality is exremely poor and the service is even worse!

My Roomba sat on the base/charger for several weeks. When I went to use it, it would not work. I ordered a new battery. It ran for like 3 minutes on the new battery and stopped. I suffered through phone calls and emails with iRobot's support only to be told it was the charging mechnisn and to order a new roomba. I didn't. Now I am condidering the external rapid charger, but I'd like to explain what mine does and see what you think. It takes many hours for it charge on the base but it does turn green. When I turn it on...NOTHING. Then the charging light is red again as if it was never charged and it takes several hours (I leave it for like 16+hours) to turn green again. But again, nothing and it goes to red again. It does this with the new battery and the old battery. Does it sound like a charging problem? I sent the new battery back and got a refund. I only have the old battery now. Think the external charger may be the answer? Or might I need the external charger and a new battery? Again, I left the old battery sitting on the base/charger for a long time (like 2 months). Or might it be something else all together???
