And we also know that the air has to exhaust somewhere. But sometimes the side vents would blow all the hair and dust all over the place. We just need a plastic side shield(Wind Ear) to re-direct the airflow up or back. The airflow will exhaust correctly and orderly. The hair and dust won't blow everywhere after using our wind ear. Make your housework more efficient. Say goodbye to anxiety. * MODEL: This Wind Ear can be compatible with Bissell Pet Hair Eraser Handheld Vacuum, Corded, 33A1/33A1W.
