Is SLAM navigation worth it for a home bigger than an apartment?

Yes — SLAM navigation turns a robot vacuum from a random bumper-car into something that cleans methodically, row by row, wall to wall. In larger homes or multi-pet households, it saves time because the battery goes into cleaning, not wandering. For a small apartment, random bump navigation is fine; for anything bigger, SLAM is the difference between “it ran” and “it cleaned.”
