Before cleaning with Roomba, clear the
floor of loose objects. If you don't vacuum
over it, don't use Roomba over it (e.g., rug
tassels, power and blind cords).
Roomba will clean based on the cleaning
mode you select. Roomba has four
cleaning modes:
Clean mode - Roomba automatically calculates the room size and adjusts its cleaning time
appropriately. Roomba may clean for up to 60 minutes.
Max mode - Roomba will run until its battery is nearly depleted, up to 120 minutes and will
then return to the Home Base.
Spot mode - Roomba will spiral approximately 3 feet in diameter and then spiral back to
where it started, intensly cleaning a localized area.
Scheduled Cleaning Mode - When iRobot Roomba receives a cleaning time from Scheduler,
Roomba enters Scheduled Cleaning Mode.When Roomba is in Scheduled Cleaning Mode,the
Status light will blink amber.Roomba will leave it’s Home Base at the specified time, clean for
up to 60 minutes, and return to the Home Base to recharge at the end of the cleaning cycle.
