Gets debris out of all but the tightest corners. Good weight to help keep it on the pool bottom. Would benefit from having brushes around the perimeter of the head.Not a very good product. It works but doesn't really cut it. We wound up getting the robotic creepy crawly instead. That actually cleans the pool.I bought this because it seemed lighter then the conventional lead weighted vacum heads! The brushes in combination with a strong vacum make it unwieldly and awkward to push, .it needs plastic wheels to stabilize the [ longer] brushes and make it easier to handle and moveCleaning a pool is not fun but this vacuum brush is user friendly, works effectively. Recommend as a backup to an automatic vacuum.ALWAYS get the one that swivels!
