The manufacturer recommends that you clean the Xiaomi 1S filters after every 3-5 cleaning cycles. But how do you know if it's time for an unscheduled maintenance?

1. Suction force decreases. The vacuum cleaner has become worse at collecting garbage, especially fine dust or animal hair, which means that the filters are clogged and the air is difficult to pass.

2. Unusual sounds: If the robot starts to hum, whistle or make intermittent sounds, this is a sign that the engine is working at an increased load due to clogged filters.

3. Smell after cleaning. Stagnant dust in the filters can be a source of unpleasant odor that spreads throughout the room while the vacuum cleaner is running.

4. Frequent app errors: If Mi Home has a notification like “Clogged filter” or “Check cleaning system”, don’t ignore them.

5. Visible dirt. You just open the lid of the trash can and look at the condition of the filters, and if they're covered in dust or there's a bunch of wool on the prefilter, it's time to clean.

If you notice at least one of these signs, don't delay cleaning. Clogged filters not only worsen the quality of cleaning, but also shorten the life of the vacuum cleaner.
