I have a Polaris 360 I am pretty sure. I have noticed my pool sweep is not performing that well. It's moving kinda of "sluggishly" on the bottom of the pool. Sometimes it will float when it goes towards the deeper side of the pool then steel down and continue moving slowly. I have a household sponge on the tail because the piece came off. Could that throw off the balance? It sucks up the debris on the bottom of the pool but not that fast. The tires rotate and are moving at a decent rpm. But I just notice the actual pool sweep is having issues staying on the bottom and picking up debris faster than it should.
How can I fix this?
New tail? New float? New wheel bearing?
