I just purchased the intex sand filter and Im thinking why not get a robot now that I have the power to. The manual vacuum does a great job with the sand pump but I hate messing with the hose and getting it primed. I was thinking of getting pool rover jr, but its as much as I paid for the pool. lol. seems like the hayward aquabug gets good reviews, but my floor is not the smoothest. will the aquabug do ok with a not so smooth floor and will it be a better option. I will be upgrading to a 24' pool this fall so it will need to be capable of handling that.
