Seems like a bad battery. The Roomba detects that there is a battery present so the battery must be at fault.

@ in one dirt devil light keeps blinking


Hi! The model number you provided M085845 is a corded vacuum that does not need to be charged. If you have a battery operated product, the indicator light will begin to blink after being plugged in for 12-14 hours or more. Try unplugging the charger for a few minutes. Hope this is helpful. If you still have questions please reach back out to us here of Fixya, Facebook.com/dirtdevil or Twitter @DirtDevil. Thanks!

When I put the battery on the charger the light on the charger stays on for little awhile the it starts to blink, but when I try to use the battery it is not charged. So I am not sure if I need a new


Hi there! It sounds like you have our Linx stick vacuum or hand vacuum model. Plug only the charger into an outlet, the blue light on the charger should flash once. If the light on the charger flashes once then the charger is fine. Try resetting the battery by following these quick steps below.

1. Remove the battery from charger or cleaner
2. Unplug the charger
3. Insert the battery into the vacuum and turn the unit on for 30 seconds (even if it has no power)
4. Remove the battery
5. Plug the charger into an outlet, make sure the light on charger blinks blue once.
6. Insert battery into charger

The light should be a solid blue, indicating the battery reset worked. If so, allow the battery to charge for 3-4 hours, completely deplete battery on your next use and re-charge. If the light on the charger is still blinking, your battery will need to be replaced. I have included a link where you may go to purchase a replacement battery if needed. Hope this helps!

Why doesn't my battery charge? Why doesn't the charger's light come on?


Hi Suzanne! Follow these steps to check that your charger and battery are working properly.

1. Unplug the charger for at least 30 seconds.
2. Plug the charger back in. The blue light on the charger should flash once.

If the blue light flashes once this is an indication that the charger is still functioning properly. If the blue light does not flash, the charger will need to be replaced. Follow this link to order a replacement charger. LiNX Battery Charger

3. Place the battery in the vacuum and turn it on for 30 seconds. (even if it does not turn on or powers off)
4. Turn the vacuum off.
5. Remove the battery and place it in the charger.

If the light on the charger is solid blue this is an indication that the battery has been reset. Allow 3-4 hours for the battery to fully charge. The blue light will start to blink slowly to indicate the battery is fully charged.

If the light on the charger is flashing blue or there is no light at all this can mean that your battery needs to be replaced. Follow the link to order a replacement battery. LiNX Lithium Ion Battery

Hope this helps!

Sounds like it could be a bad battery pack that's not accepting a charge.

Mint Plus Turbo Charging Cradle won't function properly


Cradle and contacts are fine. Cradle circuit is nothing but a reed relay and few wires, relay closes on proximity to robot's body, therefore no voltage on contacts before robot is close to cradle.
There is a thermistor inside of battery, and mine was bad. I removed it and now I am charging the battery from my bench power supply at about 220 ma current, overnight, and it works. Probably the solution is to get a new replacement battery, but the one with the thermistor inside (OEM), easily recognized by the third wire, and all should be fine, assuming that nothing else is wrong with charging circuit or power adapter (12v/1A)
Hope this will give you some ideas of where to poke.
Once successful, please post your solution.

Should the red light on my 15.6v dustbuster turn green when it's fully charged? It doesn't.


I had the same issue, then i just found the manual, in charging part, it says:"The charging indicator will be lit as long as the
appliance is connected to the plugged-in
charger."
Also it says:"While charging, the charger may get warm, this is
perfectly normal and safe. It can remain on
charge indefinitely without damage or danger. It
is not possible to "overcharge" the battery cells
with the charger provided"

It could be the power button itself. If you have a Roomba remote, try using that to power on the robot.

Battery not charging


The charger may be bad. The red light shows that power is applied to it. So usally, unless the light itself is bad, no red light, no power.
