If the red and blue lights on the vacuum cleaner are flashing alternately, it Indicates that the vacuum cleaner is in abnormal condition.
This is a problem in the air flow so please check and clean the filter, the bin and the rest of the parts. If the problem persist then you need to restart the vacuum cleaner. To do so please press both buttons during 5 seconds, until all lights are off.
Then start the vacuum cleaner normally.
If this do not solve the problem please contact our team for further support.
