I have one of these for post-hurricane / tropical storm leaf removal. I get about a garbage barrel amount of debris in the bottom of the pool two or three times a season and the thing gets them out with about a half-hour or less of work. I don’t know if it will get acorns and it definitely doesn’t get sand (use robot for sand). Depending on the nature and frequency of your debris issue, it might do the trick without breaking the bank. I’ve had mine for two years and it’s still going strong, but it is cheaply made for what it costs. For the amount of work it has saved, if it broke I’d buy another. Put a tennis ball in the bag to help the bag float up, also remove the little brush things from its underside — pointless and they block the leaves from entering smoothly.
