Product Description
 With dramatically improved navigation, cleaning coverage, vacuum pickup, and particle filtration, the Roomba 550 vacuuming robot picks up     amazing amounts of dirt and debris with the simple touch of a button. The powerful unit features innovative spinning side brushes that grab dirt and dust from corners and along wall edges, as well as two high-speed, counter-rotating brushes that pick up pet hair, cat litter, food crumbs, and other debris from floors. The vacuum sucks up the debris and deposits it into a large, easy-to-empty bagless dustbin, and its improved fine-filtration system traps dust, pollen, and other allergens inside the unit, reducing infiltration into the living environment. For added convenience, the vacuum's cleaning head automatically adjusts to transition from wood, tile, and linoleum to carpets and rugs, while improved anti-tangle technology ensures it won't get stuck on cords and rug fringe. If the unit begins to pick up a cord or carpet tassel, it will automatically reverse the direction of its brushes to extract the item. A gentle-touch bumper system senses obstacles so the vacuum automatically slows its approach, gently touches the obstacle, then redirects to continue cleaning under or around the object. Because it cleans under beds, couches, and other hard-to-reach areas, it actually vacuums more of the floor than a standard upright. The vacuum also senses dirtier areas and spends more time cleaning them, and it uses built-in cliff sensors to avoid stairs and other drop-offs. In addition, invisible barriers can be set using the unit's Virtual Wall Lighthouse system. To mark off-limit areas, simply place a Virtual Wall at a doorway or other opening and adjust the infrared beam setting to the distance of the opening. The unit automatically detects the beam and will not cross it.

• Virtual Wall Lighthouses - restrict the Roomba from off-limits areas
• Offers the latest technology and up-to-date innovations - more efficient, more coverage and better cleaning performance 
• Works on wood floors, carpet, tile, vinyl and linoleum
• Determines when to use its 4 cleaning behaviors: spiraling, wall following, room crossing and dirt detection - helps decide appropriate cleaning method for conditions
• Spiraling - cleans a concentrated area
• Wall following - uses this technique to clean the full perimeter of the room and navigate around furniture and obstacles
• Room crossing - criss-crosses the room to ensure full cleaning coverage
• Dirt detection - senses dirt and lights up the Dirt Detect light, cleaning more intensely in that area
• 3-stage cleaning system
• Side brushes sweep wall edges and work their way into corners
• 2 counter-rotating brushes work like a broom and dustpan to scoop up dirt, hair and debris
• Picks up remaining fine particles while the filter traps dust and other small particles; cleans rugs and carpets to remove dirt, dust and pet hair
