My Letro JetVac has done great service for about 18 years. But its no longer available, and parts are drying up. What's a good replacement? Here are the specs on my setup.

Pool: 18X36, about 25,000 gallons.
Square shape, radiused corners, one set of steps that would occasionally hang up the Jet Vac, but its auto reverse would un-stick it.
Shallow end, 3.5 feet, deep end, 6.5 feet.
Gunnite.

The main stuff we need it to pick up are some smaller leaves, and insect parts and worms.

We have a 1.5HP booster pump to run the Jet Vac.

We teach swim lessons every day in the summer, so a clean pool is important, and we don't want to vacuum every day. We run the Jet Vac for about 2 hours every morning before lessons, and it does real well. We only vacuum to get sand up about avery 2 weeks.

So what will replace the Jet Vac? One guy told me Pentair Legend. Is that it? Or is there something better?
