How does an above ground automatic pool cleaner work?

Do auto or robotic home and above ground pool vacuum cleaners work?

• The home one I saw at Costco.com is the : iRobot Roomba Scheduler Vacuuming Robot; does it pick up dog fur from carpets? http://www.costco.com/Browse/Product.aspx?Prodid=11234685&cm_mmc=BCEmail_307-_-FOCUS-_-2-_-Norelco The pool vacuum is here that we are looking at: http://www.costco.com/Browse/Product.aspx?Prodid=11115401&search=pools&Dx=mode+matchallpartial&Mo=74&cm_re=1_en-_-Top_Left_Nav-_-Top_search&lang=en-US&Nr=P_CatalogName:BC&Sp=S&N=5000043&whse=BC&ViewAll=75&Ntk=Text_Search&Dr=P_CatalogName:BC&Ne=4000000&D=pools&Ntt=pools&No=48&Ntx=mode+matchallpartial&Nty=1&topnav=&s=1

• Answer:

  I have the home vac (the Sage - which is designed for pet hair) and LOVE it. Now, I only have a cat - not a dog but it works great!!! This is my 2nd Roomba & I am hooked. I too, am looking into the pool vac. So far, have read great reviews. Good luck. P.S. Roomba support is wonderful & if not satisfied, return policy is great & easy.
