Yeah i found apple snails in my experience were only good for one thing... eating all the plants you painstakingly placed in your tank...
For cleanup crew, some type of freshwater prawn might help? but it will also depend on what stock you have in your tank as you don't want the shrimp picking off your fish either... otherwise, ammano shrimp may help a little?
