Working Hard to Clean the Pool

We have a robot that cleans the pool. All we have to do is drop it into the pool and plug it into an outlet; and voila. In the old days, my sisters and I would have to spend at least one hour with a pole and vacuum head that was connected to the filter. We needed to hover the head over the dirt and it would get sucked up. We needed to vacuum each inch of the bottom of the pool. We all hated that job, but we were lucky that we had an above ground pool.
