Roomba Robotic Floor Bagless Vacuum\015 I have had my Roomba Discovery for about a year and it has started to only run for about 20 minutes after being fully charged. Is there a new battery or something I can do. I love this thing, but hate to think I have to spend over $200 a year for one.\015

How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

If your Braava jet® m Series Robot Mop will not charge, it`s very likely the power cord is not fully inserted into the Home Base®. First, confirm that the outlet is working, by plugging in another device such as a lamp and confirm it works. If it does not work, move the Home Base® to a known working outlet.
Dirt or built-up debris may be preventing your robot from charging. Please unplug the base and grab a clean, lightly dampened melamine foam, such as a Magic Eraser to clean the contacts on the robot and base. Watch the following video outlining steps for cleaning the charging contacts.
Roomba E, I-Series, and S-Series Replacement Batteries

The Roomba E and I-Series robots use the same type of battery. So all of these are interchangeable. Consumers will have options to go with an original iRobot branded battery or a replacement. Check the options below for more information.

You can easily check the status of the battery in the iRobot® HOME App. A battery icon will be displayed in the top-right corner, indicating the current status of the battery.
One of the most common reasons the battery light comes on and the car battery stops charging is because of corrosion. Whether the corrosion is on the battery cables or cable terminals, it is still a problem that needs to be addressed. Another common culprit for the battery not charging is a problem with the alternator.
With proper care, your robot`s battery should last at least 2-3 years before it needs to be replaced. Here are some battery maintenance tips to extend battery life and keep Roomba® cleaning at peak performance: Only use iRobot® batteries.
Improved Cleaning Performance: A Roomba with a second battery will have double the running time, allowing it to cover a wider area and pick up more dirt. 2. Better Battery Life: By sharing the workload between two batteries, the life of each battery is extended.
Robot Battery

The iRobot® Create® 3 robot uses a standard Lithium Ion Battery for Roomba® e & i series robots. The battery shipping with the robot is a 26 Wh, 4S Lithium Ion smart battery pack, with a nominal voltage of 14.4 V (12 V min, 16.8 V max).

Charging time under normal conditions is at least 2 hours. For best results, use only the battery type compatible with your robot and ensure that it is an authentic iRobot Lithium Ion/NiMH battery that comes with Roomba or purchased from iRobot authorized dealers.
For the Roomba`s nickel-based (not lithium ion like smartphones) batteries, it`s best to keep the unit charging whenever you`re not using it. However, don`t leave it in its dock for days at a time — lots of vacuuming will keep its battery healthy.
If its battery gets low before finishing a cleaning cycle, Roomba® automatically returns to the Home Base®/Clean Base™ to recharge, providing that it was started from its Home Base®/Clean Base™.
Each eligible product sold at iRobot comes with a limited one-year warranty.
If your Roomba® i Series Robot Vacuum is not turning on or is not able to charge, rebooting your robot tends to solve most related issues. To reboot your Roomba: Press and hold the CLEAN button for 20 seconds. After you release the button, the light ring will show a white clockwise swirl while it reboots.
Most owners believe that running their robot vacuums four times per week is sufficient to keep the floors dust-free. However, if you have children or pets, you should use your robot vacuum more frequently. Daily vacuuming is recommended if you suffer from seasonal allergies.
Con: They can be less reliable and harder to fix

Not only do they need more regular maintenance (cleaning out wheels and brushes, for example), you`ll need to replace the battery every couple of years, and they can be harder and more expensive to fix.

The voltage is universal, 100-240 V.
To reset the battery and restore factory settings on a Braava jet M Series, press and hold the CLEAN button for 20 seconds. Release the button and you should see a white light swirling clockwise around the tank lid.

Battery charge I just purchased a new battery pack insert for my Roomba, Replacement
was a breeze and it now works great. My question is; The last battery I
bought ( not from you) was a full cased roomba battery pack that didn’t
last a year. Roomba says leave the r Roomba charging all the time so
it’s ready when you need it, and that’s nice but I feel that leaving it
charging like that it will kill the battery faster as it is always warm
to the touch. These battery’s should last at least 5
ANSWER : Dave you are correct. You should never over-charge anything like a Roomba, Cel Phone, etc. That will kill a bettery very quickly.

I have iRobot Roomba 4210 and I have a problem with charge battery. The battery is new. When I charging a battery in other iRobot Roomba the battery was full charged. When I charging in my iRobot Roomba the battery was empty. My fast charger is OK.
ANSWER : The charging circuit on the main board is fried. This is a common issue. You need some good electronic repair skills, and equipment, to replace the problem components

Battery temperature sensor.
ANSWER : 1. Battery configuration is incredibly important and must be matched to the requirements of the device.
.2. Battery charging is as much an art as a science. Just slapping any old power supply on a battery pack to charge it is essentially technical sue-ee-side.
.Yes, the car battery folks make it look easy; but many, many millions of dollars and development hours went into that simple-looking technology just for that reason: to make it look easy.
.You may have damaged the batteries and probably damaged the circuit board as well. There is a reason that companies spend millions in development. Unless you have a Master’s Degree in Electrical Engineering, you should stick to factory-designed and -authorised parts.

I purchased a brand new P113 Ryobi charger about 2 years ago. It has never worked. If I put a P104 battery in for a charge, it looks like it works correctly. I push the battery tester on the battery itself, and it says full charge, but when I go to use the bateery, it dies right away. I have tried three new P104 batteries. The batteries charge on my charger at work with no problem. The funny thing is, I don't need a battery in the charger and the charger does the same thing, It runs the test
ANSWER : If you have your receipt, check with Ryobi to see if it is still under warranty. It comes with either a 2 or 3 year warranty, depending on when it was purchased. If it is still covered, get it replaced/repaired. If it is not, buy the P117 charger. $30 at Home Depot. It has a 90 day satisfaction guarantee. If it charges your batteries properly, you’re good. If not, bring it back if you don’t like/want it. My P113 won’t get out of test mode now, or charge Lithium batteries anymore. So I bought the P117 yesterday. Works great, and it’s a lot cheaper than new batteries! And it has a 3 year warranty.

My Roomba Discovery 4210 seems to be dead. Specifically, with or without a battery, and whether on the charging station or plugged directly into the charging unit, I see no lights on the display whatsoever. This unit has a history of killing batteries, but now seems like it is completely dead. I understand that the batteries themselves contain fuses; is there some way to bypass the battery (for now) to verify whether the unit itself is completely dead? I should also note that this is the sec
ANSWER : Hello,

I will advice you remove the batteries from your Roomba Discovery 4210, after removing the batteries, plug the Roomba Discovery 4210 directly with the charger to an AC outlet, see if charges, if it does, it means the batteries are dead and will need to be replaced.

Take care.

Our roomba 560 wont charge have replaced the battery Tested the charing unit with another roomba that all seems ok put the uncharged battery into another Roomba but im guessing it now has a memory as this wont charge in the other hoover. Any ideas what may be wrong
ANSWER : Try cleaning the battery contacts with a little rubbing alcohol or contact cleaner on a foam swab, or a bit of paper towel. Take a litle time, it doesn’t always dissolve instantly. (Don’t use a pink pencil eraser, it would scrub off the plating that prevents corrosion) Clean both contacts on the battery pack and both of the contacts in the Roomba. Make sure the battery is oriented correctly when you put it back in. Also clean the charging base contacts and the corresponding contacts on the Roomba itself.
.I’m not sure entirely sure what you’re trying to recover – the new battery pack, the old battery pack, or the Roomba itself – but since you can swap parts back and forth, you can clearly isolate the problem. The old battery pack might be rehabilitatted if you have the equipment to recondition it, but if it may not work. The new battery shouldn’t have been harmed that easily.

My robot will not charge. Tried multiple resets and new battery from (both suggested by Irobot customer service) but got nowhere. The vacuum did work for a short time (until the new partially charged battery ran out). If I bypass the internal charging circuits and charge directly from the charger (with jumpers)
the robot seems to work fine. Unfortunatey, there is no mechanism to turn off the charge cycle, so this is not practical.
ANSWER : Replace the battery charger

After charging overnight, Roomba only runs about 25 minutes before shutting down with a red light.At this point the battery measures 15.13 volts ( about 1.26 volts per cell ) My hobby experience is that a ni/cad or ni/mh battery nominal charged voltage is about 1.2 volts per cell, and that the recommended end point voltage should be about 1.0 volts per cell. Seems like the battery is ok, butsome kind of voltage regulator is shutting things down prematurely. Is this happening, and , if so, how ca
ANSWER : Reset the Roomba by removing it from the charger, then holding “spot” and “dock” for about twelve seconds. When you let go, the unit will play an ascending series of notes. Then recharge it overnight. If the run time is still short, give Customer Support a call– be sure to have the Roomba with you when you do.
