This is my first pool and my first pool cleaner. From the beginning I have hated the Pentair Legend Platinum I have running with a booster pump. When it was new we had a lot of trouble with the hose getting stuck between the body and the wheel so that it would stop moving entirely. Every few days it seemed the thing was stuck again. After a couple of years I got used to it and it's part of my routine to untangle it now. But as of late the hose drags under the body even when it's moving. As a result the backup valve (I believe that's what the piece is called) gets rubbed against my pebble plaster which acts like a sandpaper. At this point the metal screws are all but worn out and there's actually a hole on the side where now water leaks out. The tail is also highly worn out at the tip from rubbing against the pebbles. I have gone through dozens of those foam covers but they don't last even a week against the rough pebbles.
Despite all the trouble I've had, I'm thinking of buying replacement parts to get it working again solely based on the fact I don't have the money for a new cleaner, plus the fact that when it is not stuck the Legend picks up even the oak nuts that we get once a year (and I mean a couple hundred nuts in the pool per year!) which are fairly heavy and hard to scoop up with a net from the bottom of the pool.
All this being said, I have some pressing questions/concerns. Has anybody else has these problems with the Legend? In particular, I've long felt that either the backup valve did not have enough pressure to keep the hose tightly away from the wheels, or that not enough of the floating buoys were installed. I do have two extra buoys with 2 extra lengths of hose that were not installed by the pool builder. Also, I have noticed the backup valve turns the water on and off with a mechanical "timer" so that it's not always on. I assume this is normal or intended, but I have wondered if there are "always on" backup valves and if those would be better for keep the hose away from the wheels.
Lastly, the question I'm almost afraid to ask. Seeing as how my pebbled plaster is rough on knees, knuckles and especially cleaners, is there a type of cleaner that would be more appropriate for my type of pool? I don't really want to buy a new cleaner but if I'm fighting a losing battle I guess I'd like to know.
Sorry for the long post. I've been brooding on this for years.
