Mop Pads

How do I know when it is time to replace the mop pads with new ones and the dust bag with a new one?

Wash and replace the mop pads when they’re dirty. I wash and spray mine with diluted bleach and let them air dry. I have a few pairs of spare ones to use so it’s not using the same old pads all the time. It’ll usually send a notification to change the dust bag but you can pull it out and check it yourself like with any vacuum.
