The red light by the on and off switch turned on . what does that mean

Hi. It’s either the Main Body or Battery that’s faulty. It’s rare for the main body to fail and quite common for the battery to fail.



Red = flashing 1 to 10 times means needs a new body

Red -= flashing 11 or more times means needs a new battery

Means it it full of cat/dog hair and needs emptying...

Need more info. By not working do you mean the motor is not running, the beater bar is not turning or is the red light in the rainbow unit itself.

red means dead, needs new battery

That can mean the bag is full.

YELLO and RED mean danger - clogging, not brush turning, overheating, .... it is time to RESET -- turn it all off and let it sit for half hour - that is what the manual says, check the brush that is not clogged up and check the inlet to the hose and where the hose goes into the body from the head unit where the brush is - make sure those not clogged either. Turn it on, push the RESET button on left back side of head unit by the switch that changes height. The reset button is like a circuit breaker - stops unit when overheats, starts when reset. Yello is ERROR, and fix it before it turns red and stops all the way. Cheers!!!

Clean any debris from around the brush bar. If this doesn't solve the problem you may need to take it to a qualified repair person

Hi.

If the red light is solid, that means that the Roomba is near to full discharge. If the light is flashing red, then the Roomba is completely out of charge.

If the Roomba is fully charged, then there may be a fault.

Here full list of light codes:

Pulsing Amber - Charging
Green - Fully Charged
Amber - Partially Discharged
Red - Almost Fully Discharged
Flashing Red - Fully Discharged"

There is no bag in the vacuum, or the bag is not placed in the vacuum correctly.

In the lower corner of the bag holder near the door is a little black switch, this switch must be pushed in for the vacuum to run. This is a safety so you cannot clean without a bag in the machine.
