The self-propelled unit offers nearly effortless maneuverability in both forward and reverse, while three distinct air channels lift and trap dirt, keeping it from scattering back into the carpet, so dirt ends up in the cleaner not on the floor. With red and green lights, its embedded DirtFinder system indicates areas that may need more cleaning attention. The green "clean" light remains on while vacuuming except when the detector senses a larger amount of dirt; red "dirty" light illuminates to suggest additional vacuuming in the area until the light changes. Even more, it provides a deluxe stretch hose, a complete on-board tool set for above-floor cleaning, and a pet-hair tool with rotating brushes that effectively removes stubborn pet hair and dirt from upholstery and carpeted stairs. Other thoughtful details include non-marring wheels with bearings for lower push effort on carpet and safe use on bare floors, custom cleaning controls for moving from carpet to bare floors with ease, and an ergonomic D-grip handle for added comfort and control. The cleaner also comes with fingertip on/off power control, five-position height adjustment, edge-cleaning bristles, a headlight, and a 31-foot power cord.
