What are the key differences between a shop vac and a dust extractor, and which one would be more suitable for heavy-duty cleaning tasks?

A shop vac is typically used for general cleaning tasks and can handle wet and dry debris, while a dust extractor is designed specifically for capturing fine dust particles and is more suitable for heavy-duty cleaning tasks that involve woodworking or construction. For heavy-duty cleaning tasks, a dust extractor would be more effective in capturing fine dust particles and maintaining a cleaner work environment.
