iRobot Roomba 560 Product Manual - Page 7

Cleaning Pattern Roomba is a robot that cleans floors differently than the way most people clean their floors. Roomba uses its robot intelligence to efficiently clean the whole floor, under and around furniture and along walls. Roomba calculates the optimal cleaning path as it cleans and determines when to use its various cleaning behaviors: Spiraling: Roomba uses a spiral motion to clean a concentrated area. Wall Following: Roomba uses this technique to clean the full perimeter of the room and navigate around furniture and obstacles. Room Crossing: Roomba crisscrosses the room to ensure full cleaning coverage. Dirt Detection (selected models): When Roomba senses dirt, the blue Dirt Detect™ light is lit and Roomba cleans more intensely in that area. TIP: R oomba takes approximately 25 minutes to clean an average room and will pass over the same area of the floor multiple times to ensure total floor coverage. TIP: F or most efficient cleaning, clear your floor of clutter and use a Virtual Wall to confine Roomba to one room. For more detailed information, visit: www.irobot.com 7
