I think that the plug in battery charger has burned out. The green light comes on while it is charging, but then it turns red when I unplug it. Is it possible to replace it? Also should I keep it plugged in all the time? I think that's what happened to this one. I have model 4100. Thank you. Judy Karnes XXX@XXXXXX.XXX
Optional Information: Make: iRobot Model: 4100 Already Tried: Unplugging and waiting for awhile and plugging it in again. Lights come on but nothing is really happening.
Hello, I'd like to help you with your question. Please remember to click the accept button if you are satisfied with my answers.
Are you referring to the light (red/green) on the charger base itself, or on the robot?
it is on the robot. i don't have a base, just a cord that plugs in and then there is a box that has a light and then there is a cord that goes to the wall outlet.
Ok, that box is part of the charger. It is normal for it to light green when charging the robot, and turn red when not charging (which will happen when robot is unplugged, or when still plugged in but the battery is fully charged)
Does it seem that the battery is not charging at all?
It is ok to keep it plugged in all the time, though you may find it will have a longer life if it is unplugged when not in use. It will also save a small amount of electricity.
yes - there is no power in the robot at all.
Ok, since you have a light on the charger, it's more likely that the charger is good, but the battery inside the robot has gone bad.
This is not uncommon, as rechargeable batteries have a limited life span and are only good for a limited number of charge/use cycles
how do i get a new one?
You can order them online, I'll get you a link.
Just a moment please
is it easy to change?
Yes, it should come with instructions. You'll just need to remove a few screws to the battery compartment cover, pull the old batt out and swap in the new one.
Here is a link to order one online: Battery for iRobot Roomba
You should see a link on the same page for a charger as well, should you be interested in having a spare.
thank you. I hope it works. I really like using it, but I haven't for awhile and i guess that's why it burned out. Should i keep it plugged in all the time?
It's ok to keep the charger plugged into the wall all the time, but after the battery is fully charged, I wouldn't keep the robot plugged into the charger all the time (it should take 7 hours for a full charge) as that can harm the battery life.
With normal use, you can typically expect the battery to last 1-2 years.
okay! Thank you.
