Midea 12175000A47381 sponge filter for P5

Midea 12175000A47381 — cordless stick vacuum sponge filter for the P5. A stick vacuum filter does two jobs: it keeps fine dust inside and protects the motor from abrasive grit. Clogged, it first eats the suction, then heats the motor, and only after that does the cleaning result give it away — which is why it is changed by the calendar rather than by how it looks.
