How to keep objects in space from floating?

In space, anything can float anywhere because there is no gravity. This has caused many problems to life in space, and people have also thought of many ways. For example, the rotation of the space station produces centrifugal force, resulting in artificial local "gravity." For garbage, vacuum adsorption is used to prevent dirt from floating in the spacecraft. There are also methods of making "gravity" with magnetic shoes. Of course, the most important thing is the living habits of astronauts, not throwing things casually. This is the most important thing.
