Reason 1: Clogged Filters The most obvious reason your Dyson keeps saying filter needs cleaning is that the filter is clogged. Over time, the filter can become blocked with dirt, dust, and debris, reducing airflow and triggering the sensor. This is especially true if you have pets, allergies, or live in an area with high levels of air pollution.
If your Dyson vacuum is not working after cleaning the filter, the filter might still be wet, and the Dyson vacuum won't work until the filter is completely dry.

Dyson cordless vacuum filters are engineered to capture microscopic particles. Over time, these can build up in the filter and reduce performance. By washing it at least once a month, you can help maintain suction power.
In this video, I will try to confirm that, in this case, the displayed filter error is caused by a software problem. After replacing the Dyson V11 filter, the cleaning alert may remain due to a sensor reset issue. To reset, power off the vacuum, then press and hold the trigger and power button simultaneously for 10 seconds until the light blinks.
Regularly wash the filter every month and let it dry completely before reinstalling. Persistent alerts can indicate sensor malfunction or firmware glitches. Here's How to Fix It? If your Dyson vacuum cleaner has stopped working after you have cleaned the filter, probably the filter unit is still wet.
The issue might also surface if the filter is not installed properly or the motor head has failed. The device won't function if the filter has worn out. If your Dyson V10 is not working after cleaning the filter, check that the filter unit is attached correctly.
It's also possible that the filter is still wet after cleaning because it hasn't been given enough time to dry thoroughly, or that the motor head has failed after sucking in water from that wet filter. It now needs its pre-motor filter washed after every use and is covered in fine dust every time I take it out. My theory is that the cyclones aren't filtering out the fine dust properly, therefore sending it straight to the filter.
I recently called Dyson about the issue and they sent me a new filter under the guarantee. Even the best vacuum cleaners need regular care, and knowing how to clean a Dyson vacuum properly can save you from premature replacement.
