I have a 28' round AG with cartridge filter. When I bought the pool 4 yrs ago, I also bought a ladybug vacuum. Up until now it worked fine, now all it does is float onto its side after about 15 seconds vacuuming. Does anyone have suggestions on why this is happeneing or possible better vacuuming products?

Also, I want to shop around for a solar cover this season. Does anyone have any suggestions.

Thanks.
