Bissell CrossWave HydroSteam Strainer for 3515, 3518 PROCLEAN Verify your X7 or X8This genuine Bissell CrossWave strainer (Part #163 4581) fits HydroSteam wet dry vacuum models in the 3515 series and model 3518. The strainer sits inside the dirty water recovery tank and screens out hair, lint, and larger debris so the collected mess is trapped and the recovery path stays clear. A clogged, torn, or missing strainer lets debris pass through where it can restrict airflow and reduce suction, or makes the tank harder to clean.
