The battery would have completely drained if you ignored the red led flashing when vacuuming the floor.

And it will not charge until you plug it in for at least 3 hours. So, plugin your Vax ONEPWR into the charger and leave it for at least 3 hours.

When you unscrew the battery pack, you’ll find a series of five 3.7V 1800mAh.

    • If there is a build-up of debris around the brush roll preventing it from turning, then the power will automatically stop and the charge light will flash red. You should remove the brush roll and clean it.

  1. The red light is flashing when I have my battery on charge as it keep cutting out when I tried to clean floor. Roller brushes are clean??

    This is virtually brand new cleaner…

    Please can you fix this yet again

Just rang Vax and they have replaced them free of charge on warranty
