The 
		Cleanup feature lets you remove unwanted geometry from a polygon mesh (for example, zero area faces or zero length edges). You can also tessellate faces that may be valid within Maya, but not in a game console, such as concave faces, or faces with holes. 
	 
Tip: Select the 
		Remove Isolated Components options before performing a mesh cleanup to remove orphaned components that are created during modeling operations. 
	 
Note: Because the 
		Cleanup feature has the ability to merge vertices and collapse zero length edges, there may be situations where the 
		Cleanup feature can output non-manifold geometry. This can occur when you set the 
		Cleanup options to perform multiple cleanup operations on a mesh in a cascading way. If this situation is likely, it is recommended you run the 
		Cleanup feature multiple times and turn on the 
		Non-Manifold Geometry option in the 
		Remove Geometry section only on the last iteration.
