Hose weights for AquaNaut 250?

[EndlessSummerAZ]

Does anyone here use an AquaNaut 250 with hose weights? I’m trying to be able to keep the Aquanaut and Betta in the pool at the same time. I’ve tried a couple of weights from Amazon and they are too small or too large. No luck finding any Hayward sells.

Some listed are actually floats - used on the leader hose at the cleaner itself to hold the hose upright in the water.
Some of the others are weights - no idea if they will work for your intended purpose.
