Hi there,

Well first of all you may check that the charger (adapter) is working or not, you may use a volt meter to check it out or use another charger to make sure....... further you may follow the step below -
1. Remove the battery pack from Vacuum.
2. Hold down the power button for five seconds.
3. Reinstall the battery to reset the system.
4. Plug the Charger directly into vacuum.
5. Charge the battery untill the power light is solid green again and keep the vacuum on the charger for an additional 72 hours (3 days). Important: Do NOT interrupt this charging cycle.
If further you have the same problem it means it's time to change the old battery with new one.

Good Luck!!

Thanks for using FixYa!!

    How do you get the vacuum apart so that you can replace the battery pack? That seems
    to be the real issue that noone has addressed.

Obviously, you need to change out the battery pack - I had the same problem after years of using my KONE. My email to Dirt Devil was quickly answered by a kurt response of "there are no consumer serviceable parts" in the KONE, and Dirt Devil did not offer to do the job for me. Thus the challenge of changing the battery pack was laid down... and conquered. Here's how to do it:

First, buy yourself the cheapest 3/4-inch wide steel tape measure you can find. You won't be measuring anything with it. Cut off four separate 12-inch sections of the tape measure with scissors. On one end of each section, cut an obtuse point.

Now, take your KONE and remove the "snout". Look down at the top of the motor mechanism and you will see four equally spaced indentations in the out edge of the motor/fan mechanism. The mechanism (itself an inner cone) is latched into the outer cone housing by four integrally molded outer lock tabs.

This is the fun part. Carefully insert each of the tape measure sections between the inner motor mechanism and outer housing molded locking tabs. Do this by working the pointed steel tape measure section between the inner & outer parts. I found this is most easily done by working the tape section from the side of the tab, not by stabbing the point straight. Its' a tight fit, but it can be done.

After all four steel tape sections are inserted (I pushed them in about six inches), using your hands only, grip the inner mechanism and firmly try to "rock" the mechanism out from the outer housing. It took me some effort, but after working it a couple of minutes, the inner mechanism popped out.

Use a Phillips screw driver and remove the eight screws that hold the inner mechanism together. Gently work the two mechanism halves apart. You'll see the battery pack, which consists of six rechargeable C-size NiCad batteries tack-welded together. Slip the two wire motor leads off of their battery pack connectors and remove the battery pack.

Now what? Well, I took the battery pack to my local Batteries Plus store. I hope you have one nearby, because you're not going to be able to get a replacement from Dirt Devil. I showed the technician at Batteries Plus the battery pack and got a response of "No problem. Five minutes. $25." Actually, it took him about four minutes to tack-weld a new pack with the wire connectors. It still cost $25 - well worth it.

To reassemble, just reverse all the steps, except you won't need the steel tape sections to put it back together. Just insert the inner mechanism into the outer housing and push.

My KONE now works like new - Good luck with yours.

    Update - to easily remove the inner cone, just push on the motor start button - should quickly slide out.

If you're sure the battery contacts are clean and the battery really is charged, then there is faulty circuitry within the Roomba that would have to be repaired or replaced.

Confirm that the battery is inserted with the metal contacts down so they make contact with the spring terminals in the battery compartment.

Visually confirm that the metal contact plates on the battery pack, and the spring terminals in the battery compartment are clean and shiny. If not, wipe with a clean cloth or paper towel, its OK to use a little water or rubbing alcohol on the cloth, if needed, and then dry it.

Visually confirm that the metal contact plates on the Roomba, and the spring terminals on the docking station's home plate are clean and shiny. If not, wipe with a clean cloth or paper towel, its OK to use a little water or rubbing alcohol on the cloth, if needed, and then dry it.

If you have a volmeter, measure the voltage between the contacts on the battery pack If it isn't something in the neighborhood of 14 volts and is 11 volts or less, the battery isn't fully charged.

Reinstall the battery.

For the moment, please connect the power adapter directly to the Roomba rather than the docking station to eliminate one possible faultly connection.

If the battery wasn't fully charged, or you weren't able to test it, try to charge the Roomba and then retest the battery voltage if you can. If the battery voltage was higher immediately after charging, but didn't get to 14 volts, the charger is good, but battery needs to be replaced. If the battery voltage was unchanged after attempting to charge the Roomba, the charging circuitry may be faulty. If there was no light patterns when you tried to charge it, and it was plugged in to a good outlet, then the power adapter or charging circuitry is definitely bad.

If you have no voltmeter and you cleaned the contacts and tried to charge the Roomba and it works, use the Roomba and then recharge using the docking station and see if it was just dirty contacts or it won't charge through the docking station. If it didn't work, you'll need to figure out if its the battery, the charging circuitry in the Roomba, or the power adapter. If there are no lights when you try to charge the Roomba, then Either the power adapter or the Roomba power circuitry is defective, but without a voltmeter you can't find out which one, and there's no way to know if the battery is good or bad, but you know Roomba wasn't trying to charge it. If there are lights when you try to charge the Roomba, then at least you know the power adapter is good. Unfortunately, without being able to test something there's no way to distinguish between a charger that won't deliver a charge to the battery and a battery that won't accept a charge. If you want to take a guess then a bad battery is more common and less expensive to fix.

Shark won't hold charge


How long are you letting it charge for? It's also possible the battery is defective, or there is a short in the vac.

I bought Dyson DC16 in 2008. Charged full but it only last for 1 minuet. Should I get a new charger? Is Dyson going to send me a new charger?


Your battery is losing voltage too quick. It has probably developed a 'memory'. Dyson claims that their handheld has the best suction out of all the handhelds out there. In order to maintain that claim the circuit board will shut off power to the motor when the voltage drops below adequate charge for full suction.
We need someone who can teach us to bypass that part of the circuit so it won't cut power to the motor or you need to get a new battery.
Shorting the battery like an Aircraft battery then re-charging won't fix it.

Fully charged, filters cleaned, vacuum keeps shutting down in and then starts again only to shut off again. the 6 minute time limit is not used up.
