We never had a pool before we purchased this house, excited that we purchased the previous owners aquabot we thought cleaning the pool would be easy. It was, toss in the robot, and it did the work, but then we had to clean that horrible bag! It was disgusting, so I knew someone else had to feel the same way as I did, so I looked on line for a disposable bag. I'm so glad I found Nasty Bag! It allows me to truly enjoy my pool, the bag fills up, I toss it away...Thanks Nasty Bag!
