Question about Roomba Robotic Floor Bagless Vacuum

4 Answers

I have a Roomba 560 (it's still in warranty !!) and, after my summer vacation, it has a problem. When I'm charging Roomba, the orange light blinks (and this is normal!) but this orange blinking continues forever.... the light doesn't change to green. If I detach Roomba from the charger, the light become green and it works normally until the light changes to red and I have to charge it again. WHY, DURING THE CHARGING PHASE, THE LIGHT DOESN'T CHANGE FROM ORANGE-BLINKING TO GREEN? HAVE I A PROBLEM WITH THE CHARGER OR WITH MY ROOMBA? thanks a lot for your help ciao Carlo Perego - city:Zoagli , country: Italy

    thanks a lot DrifterK,

    but my main question was to understand if there is a trick to solve my problem or if there is some trouble in my Roomba or in its charger :)
    If your idea is that it has a minor trouble, being the Roomba inside the 2 years warranty, I prefer to send it to the Italian warranty service center. why not !!!!!! It isn't my intention to open my Roomba or its charger.

    Only a note for your comment:
    you wrote: .... I bet if you reconnect it when the battery is charged it shows the green light directly ....:
    no, if I do this, the light remains orange blinking :)

    Thanks a lot and have a nice day.
    ciao from Italy :)
    Carlo

    thanks again. I'll contact the Italian IROBOT service ppl but.. I think that I'll follow your suggestions :)

    ciao

    thanks for your 3 solutions: 'fixia' is a magic help !!. I asked also a suggestion directly to the IROBOT service and they suggested me to reset my Roomba to reset the battery control system (pressing both the DOCK and SPOT buttons for 30 seconds). This solved my problem. Consider that I received the same suggestion also from FIXYA's experts.
    Thanks a lot

The problem is not with the charger itself but it is with the battery inside the Roomba. It sunds like one or more of the cells has gone bad so its not holding the same charge as it did. I would recomend sending it in while the warranty is still valid so they will replace it. Your charger and the Roomba itself should be fine.


A few tips to keep the battery working longer:
Only charge the battery when it is drained all the way to zero. It will help keep the battery active.

Only charge the battery until it is full and then disconect it from the power source. It will keep it active longer plus it will help keep your electric bill down.

The best thing you can do is to contact the manufacturer, since they are the ones who would know for sure if the charger or unit was defective. I would think it's some kind of voltage sensor or comparator in the Roomba itself, but since the unit works, it may not deter the functioning of the unit at all.
If you have a voltmeter, you can measure the charger output and charged battery voltage, it should be 22.5 v for the charger output and the battery should read 17 - 18 v.
Check with support, just to make sure. Good luck, and hope this helps.

This i snot a functionality problem ..but just a repay issue in the charger...which causes it to not detect the maximum value of the accumulator and signal it ..when it is in the charging mode...after you remove it ..the full mode is detected and all normal ..I bet if you reconnect it when the battery is charged it shows the green light directly ..
so this is not quite dysfunctional but just a small issue with the display of the lights..
The worry stuff will be on it will not charge and the green light will not be displayed at all..Than yo will know that the top value is not achieved..My advice is to let it be cause it is sensitive and you can do more bad than good by opening it up..
Another issue is the detection in different mode by the charger and the battery of the top charge ..if one is detecting at 95% and shows green light ..and the charger (when in charger mode) ..has its relay detecting a full charge at 98 % ...and the battery never gets to that point cause it is already a little old..than in the charger mode will not show the green light cause it never gets to 98% but after removed it showing it ..cause the internal relay detects full mode from 95%..
The idea is that *** long it still gets to the green light it means is charging enough ..
So..if it is not broke ..dont try to fix it ..

    In this case if it is under the warranty it is worth to send it ..the issue is that it is a slow process and it will take a while ..The issue is not on the device itself but on the battery that will not charge the max to trigger the green light ..that's all..this light is triggered on the max charge ..and the battery level is never achieved..the cause it can be double...either the voltage is not achieved due to the charger cause of the relay ..or the relay condenser of the charger ...(most probably ) or the battery being kinda time-marked already ...is not capable to store the max charge ..and so is not triggering the green light ..It works the same and it is obvious that it is charging ..but not to the max..that's all...To have it fix cause it is in warranty it is a good move ..but it will take time ..being shipped to the dealer ..and such .and yo will not be able o use it ..I say so cause I had a similar experience and it took about a month ..

Hi,
I think that it would be a problem with the charger...but I would take everything back and have them check out the battery also...it really could be either one and they will have to check them both to be sure...
If it is still under warranty do not take any chances the repairs will cost way to much...
Get it fix now while you do not have to pay for it...

Roomba 560 fully charges. Runs for 2 seconds fully green and just stops. And lights up red.????


Set him on the floor, after powering him off and then back on, and press the "Clean" button three times. This will reset him.

IRobot 560 does not return back to the charging station as it runs out of battery after 1/2 hr. of cleaning.


You need to put the charging station in an easily accessible area, since the roomba doesn't know where it is if it's in another room. The roomba needs to be quite close to it to be able to detect it. When its battery runs low the roomba will zigzag around at random until it detects the charging station.

Roomba 550 was plugged & docked in for 3 wks without being used (on vacation) & now it won't work or charge. Unit is 3 months old.


The battery sounds like its dead.. Leaving it on a constant charge is actually bad for the battery. Sorry to tell you but you need to either get a new vacuum or take it back to the place you got it and have them take a look at it and perhaps replace the battery.

With the money you spent of that "vacuum" you could of bought a much better vacuum cleaner that would last you much longer.

Also, if it's only 3 months old I'm sure there's some kind of factory warranty in place for something like this. Give the manufacturer a call and see what's up.

Hope this helps you

My roomba mounts up to the charger the light blinks red then after a time it goes green but when I dismount it and push the green button it immediately goes red. It doesn't beep or do anything. It is that...


You have dead nimh (nickle metal hydride) batteries. You will need a replacement. You can test for this by removing the battery and holding the power button for 15 seconds. This will restart the charging cycle as if the battery were new.

Roomba goes a few minutes after a charge then stops


you can try cleaning the battery and charging contacts with some rubbing alcohol or contact cleaner, but its also possible the battery has reached the end of its service life.

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.
