How long it lasts
Replace it when the mesh is torn, cracked or worn at the edges, or stays brown or green after a deep clean, Maytronics says; rinse it after every cycle and deep-clean it about once a month.
After replacing: No reset needed. Robots with a filter indicator on the power supply or app clear it after the filter is cleaned and a new cycle starts; the manual for your model has the details.
