Cordless stick vacuum or robot vacuum for a primary cleaner?

The mainstream consensus across the reviewers we read is that a robot handles maintenance cleaning but a cordless stick is still needed for deep cleaning, stairs, upholstery, and pet messes. Several r/VacuumCleaners contributors note that even premium cordless models like the Dyson V11 are best treated as a primary or secondary depending on home size, not a single-vacuum solution for large carpeted homes.
