Question about iRobot Roomba 4210 Bagless Robotic Vacuum

1 Answer

I have the IROBOT discovery that just got a new battery. IT ran great! As the battery was dying, I put it into the home base. The "brick" is green, the home base has two green lights and the on/off pulsates red. It never charges though. Eventually the red light stops pulsating. Customer service said to reset it, clean the metal, and nothing works! They told me to just buy another one. The problem is that I know it was working! Help!

The best thing that you can do is take the charger into somewhere that can test it for the proper output voltage. It should be somewhere very close to 22 volts with no fluctuation. The charger is the easiest thing to test in this case.

Amber flashing light while on home base. New, pulled tab, placed on dock. First time said charge err1, took out battery and replaced. Now just flashes amber. Is this correct?


Your manuals are here. Flashing lights must be covered. A quick look at the site says flashing red is bin full. In fact, I found it. Flashing Amber is CHARGING.

IRobot 530 charges intermittently


Reset the Roomba: hold down "spot" and "dock/demo" for fifteen seconds, then release and listen for the tune. Then charge the Roomba overnight. The next time you run it, the unit should run longer. If not, call support and let them know you may have a battery problem. 1-877-855-8593 (I strongly encourage you to have the Roomba with you if you call.)

My Roomba Discovery doesn't appear to hold a charge


cor2an,
That sounds like a classic battery failure in the Roomba discovery series. There are sensors inside the battery pack that go bad too. Either way...it's not very practical to repair the battery....the best shot you have would be to order a replacement battery. You just pop the old one out and then put the new one in.

They are available from iRobot for $69 at this link: http://store.irobot.com/product/index.jsp?productId=2799714&cp=2804606.3358509&ab=CMS_AccSuper_Roomba400_102308&parentPage=family

There are sources of less expensive (about $35) Genuine iRobot quality batteries also. You could try www.RoboticVacParts.com at this link: http://cgi.ebay.com/OEM-iRobot-APS-battery-Roomba-400-4XXX-Discovery_W0QQitemZ270412120603QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3ef5d1821b&_trksid=p4634.c0.m14.l1262&_trkparms=|301%3A1|293%3A1|294%3A30

Irobot moving slowly


Try running th roomba with the dust bin removed to see if the main brush is turning, if not it could be an issue with the gears being stripped in the brush motor assembly or inside the brush compartment holder. If the gears are fine the brush motor itself may be blown. A new one is about $30.00.

It sounds like the battery is shot. These batteries only work for a couple of years and then they won't accept a charge any more. A common mistake people make is recharging them before they need it. This will make the battery "lazy"
Contact the manufacturer for more info.

Roomba 4200 Scheduler


The best for the battery if (NiMH). Discharge completly, than charge full (charge more even the charger indicates full charge)

Clean every part, maybe a hair slow down the wheels and thats why need more power.

Here some tip from the web:


With proper care, one iRobot Roomba battery can last for hundreds of cleaning cycles before you need to replace it. Here are some things you can do to extend Roomba's battery life and keep Roomba cleaning at peak performance:



Use your Roomba frequently. Your Roomba is powered by a rechargeable nickel metal hydride (NiMH) battery, which lasts the longest when you use it regularly.



Keep the brushes clean. If the brushes and brush axles get clogged with hair and other debris, your Roomba will strain to spin them, using more battery power than normal. In extreme cases, the battery can even be damaged. See How to remove and clean Roomba's brushes



Keep your Roomba plugged in when not in use. If you have a Home Base®, keep your Roomba docked in the Home Base and plugged into the charging brick. If you don’t have a Home Base, keep your Roomba plugged into the APS Fast Charger.



Make sure you are charging your Roomba correctly. When your Roomba is plugged in correctly, the solid green light should be illuminated on the charger or on the Home Base.



Plug your Roomba in as soon as possible after using Max Mode. Leaving your Roomba unplugged for more than 24 hours can damage the battery.



Place your Roomba and the Home Base on a smooth, hard surface when yourRoomba is plugged in. Make sure your Roomba and the Home Base have plenty of space for ventilation. Do not charge your Roomba on a carpet or rug.



Charge and store your Roomba in a cool, dry place. Keep your Roomba out of direct sunlight and away from sources of heat such as windows, radiators, heating vents, and large appliances.



Remove the battery when not using your Roomba for a long period of time. If you will not be using your Roomba for more than a few weeks, fully charge the battery, remove it, and store it in a cool, dry place. When you want to use your Roomba again, insert the battery and fully charge it. Leaving your Roomba plugged in for weeks when it is not being used can damage the battery.

You can purchase a second battery or replacement online at the iRobot Store.
