Are you talking about a pool cleaner? Look for something with "low flow" ability, like the Sta Rite Lil Shark - it will work on VERY low flow, it will also clean a smaller pool like that in a snap! They are suction side cleaners, have an adapter that just gets pushed on for those type pools and you put it in your suction/skimmer opening (the suction side screen/cap has to come off) If your pool has one of those over the wall skimmers with it, this is used INSTEAD of the skimmer in the suction hole. I would guess the vac head could be used the same way, using the telescoping pole attached to it to move around. I like the automatic cleaners because I'm lazy - used the Lil Shark on our 18' round intex we had for many years before our big pool.
