Roomba Robotic Floor Bagless Vacuum\015 Hello, I found a roomba discovery without a battery and charger, just the robot. I made a battery package with 12 x 2450 AA NiMH energizer cells that I had and connected them to the roomba it’s alive! but now I want to charge the batteries using the roomba. I have a 24 volts 1.3 amps power supply and I connected it to the roomba. When it is connected the roomba doesn’t start (I thing this is normal please confirm) but the problem is that when i messure the battery contacts tho check if the batteries are receiving charge, there is no voltage. Also there is no indication of any led that the roomba is charging..I was thinking that the roomba is not sending charge to the batteries because it is not receiving the temperature sensor signal (can be this possible?).So:.This voltage it’s ok to supply the roomba an charge the batteries?.Do I have to see any indication when the batteries are charging?.Can I simulate (with a resistor or someting) the temp sensor?\015

How to Identify and Fix Common Vacuum Problems ?

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

The infrared sensor at the very front of the Roomba allows the vacuum to bounce light off an object to detect its presence, even if it`s cleaning after dark and there`s limited natural light.
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.
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).
While Roomba is cleaning, it avoids steps (or any other kind of drop-off) using four infrared sensors on the front underside of the unit.
An example of a sensor used in some robots is called LIDAR (Light Detection And Ranging). LIDAR is a technology that uses a laser to measure distance. Lasers illuminate objects in an environment and reflect the light back.
With proper care, your robot`s battery should last at least 2-3 years before it needs to be replaced.
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.

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.
The standard sensors are located on the robot vacuum`s bottom and bumper.

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.

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

Can you take the Swivel Sweeper battery pack apart to replace the batteries with new rechargeable batteries? Batteries look like AA or AAA, but it appears that the battery pack is sealed. Is there any way to get it apart:?
ANSWER : Yes you can if you have a way to cut through the plastic outer case,(I used a Dremel rotary tool). Inside you will find six double A Ni-mh batteries. I found eight of these for sale on ebay for around ten bucks,then all you do is solder some wire to the batteries like the original battery pack and tape up the case and charge.

The battery charger flashes red when the battery is inserted for a charge – does this mean the battery is no good? If so, where can I purchase a new battery and at what cost? Thanks in advance.
ANSWER : Blinking red means it is charging. it will stop blinking when it is fully charged.

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.

Front wheel problem
ANSWER : I would send it to protechrobotics. they will test all your components and let you know what needs to be done. if the repair is more than it’s worth–they will help you out too.
