The vacuum hovers and scrubs the same piece of floor for a while (almost 30 seconds sometimes) to make sure whatever stubborn grime is getting the extra attention it needs. Depending on the size of the stain, the whole vacuum will also swing back and forth in a half circle to come at the stain from more than one angle (the same idea as Shark's Matrix Cleaning system in previous vacuums).

Quadtrees are everywhere spatial data exists. Mapping services use quadtree-like tile pyramids to serve map tiles at different zoom levels (Bing's quadkey system, for example, addresses tiles as base-4 paths). Game engines use them for collision detection and visibility culling. Geographic information systems use spatial indexes to store and query spatial datasets. PostGIS uses GiST indexes (R-tree-style) for spatial queries on geometries, while PostgreSQL's core supports quadtree-like SP-GiST indexes for certain data types like points.
