Is the Shark robot vacuum actually worth it?

How the Shark's grid pattern actually cleans a room

Here's what I'd want to know first: most robot vacuums clean the way a distracted person cleans, bumping around in loops until they've covered enough floor to call it done. The Shark's Matrix Clean mode does something different. It moves in a straight-line grid, back and forth across the room, then repeats the pattern from a slightly offset angle. That overlap is the trick: two passes at two angles catch the crumbs a single bounce-and-hope pass leaves behind, especially along baseboards where targeted edge airflow pulls debris out of corners instead of skating past them. The suction has to keep up with that route, and it holds steady across carpet and hard floor without you switching a mode. Once the run is done, it returns to its base and empties itself into a sealed bin that holds up to sixty days of dirt, and that's the part worth knowing: you stop thinking about the vacuum between empties, not between cleanings. If the battery runs low mid-room, it docks, recharges, and picks the grid back up exactly where it left off, so a big open-plan floor doesn't end up cleaned in two disconnected halves.
