Most robots handle 1600-2100 sq ft on one charge. Roborock S8: up to 3200 sq ft. Roomba j7: 2000 sq ft. For >2100 sq ft, choose a model with auto-empty station and large battery. The robot automatically returns to recharge if needed and resumes where it left off.

No! That's the whole point. Schedule it to clean while you're away (work, errands). Recent models (Roborock S7+, Roomba j7) avoid obstacles (socks, cables, pet waste). Just make sure doors to rooms being cleaned are open and there are no small objects on the floor.
