Won't charge but still flashes on also will run for 30 seconds

Category moved from 'Cars and Trucks' to 'Vacuums'.

If it was running okay before it went on charge and doesn't now, it is likely to be an electronic fault. They make it so that you can't run the vacuum whilst it is being charged. Try removing the battery for a few hours.

This means the batteries are no longer able to be charged and have to be replaced.

Suspect the battery has died and needs replaced Reviewing The New Logitech Wireless Trackball M570 Pc Mouse AmanStino

It's only a few months old though! And I have lost the receipt. Looks like I'll be buying a new one, thanks though.

1) replace again the batteries by new ones and completely charged.
2) test the charger if if functioning properly, can be faulty, and not charge well the batteries.
3) test the power supplies inside from the scuba, to due some short circuit drain the batteries.
God bless you

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.

If you have a 400 series Roomba, try removing the battery, then holding down the power button for ten seconds, then recharging the unit before you run it again.

If you have a 500 series Roomba, don't take out the battery-- just press and hold the "spot" and "dock" buttons for about fifteen seconds. The Roomba will play a tune, and you can then charge it and try running it again later.

First drain the battery completely and then take out battery and charger and hold power button for 30 seconds and then clean the roomba with compressed air take out all compartments and blow air thoroughly everywhere especially near the wheels where the wheel sensors are. Leave battery to charge for full day and try to run.

Like all batteries after a while they go bad/will not hold a charge. especially the kind that is always plugged in/always charging, like electric shavers, cordless vac and so on.
