additional mop heads for my S5 max I found the squeegee to be a bit more grippy in one direction compared to the original pad. This extra grip prevents the robot from turning on the carpet and takes twice as long to vacuum the room while getting stuck in steps it doesn't have with the original pad. They work great, if only on uncarpeted surfaces, but my house is a mix of carpet and wood. It is not the same as the original seal.
