What are the different Cleaning Modes of the Roomba 500 series?
The Roomba 500 series has three cleaning modes and will clean based on the cleaning mode you select. Clean Mode (all models) Roomba automatically calculates the room size and adjusts its cleaning time appropriately. Spot Mode (all models) Roomba will spiral approximately 3 feet in diameter and then spiral back to where it started, intensely cleaning a localized area. Scheduled Cleaning Mode (Models 550 and above) When a cleaning time is programmed, Roomba enters scheduled cleaning mode. When Roomba is scheduled to clean, it will occasionally flash its next scheduled cleaning time to indicate it is scheduled. At the specified time, Roomba leaves its Home Base, cleans, and then returns to the Home Base to recharge when its done. NOTE: When using Roomba with Virtual Wall Lighthouses™, Roomba will clean for approximately 35 minutes per room.
