When my children were younger I had them clean up their toys when they were old enough to get them out of the toy box. We always had plenty of books to read, and feel. We also had lots of puzzles, instruments, and ride on toys. The children did not put the toys in the box perfectly, but they put them in the box. When children feel like they have achieved something they want to do it over and over to please you. Learning to do something for themselves. It is a step in the right direction, little steps to do something to participate in cleaning a space they live. Part of being a family is participating in the family dynamics. One aspect of the dynamic is cleaning up after yourself and helping out everyone else. Start them out early, so they have pride in the place they reside.
