The Dyson Cinetic Big Ball Multi Floor is a powerful upright vacuum cleaner designed for multi-surface cleaning. The Cinetec series features an active base plate under the cleaner head which self-adjusts for optimal contact with all floor types. While cleaning carpets the plate rises and the brush bar lowers to penetrate different depths of carpet pile, successfully uprooting ground-in dirt and pet hair. A reconfigured brushroll gives 65% more power than previous models. Without needing to bend down or make adjustments to the cleaner head the Dyson Cinetic Big Ball Multi Floor smoothly transitions to hard floors. On hard or delicate surfaces the brush bar retreats to protect the floor while the base plate lowers to create a seal for more suction power. The Cinetic Big Ball Multi Floor uses patented Dyson Ball technology for easy maneuverability. The attachment set includes a Combination tool and Stair tool. The Tangle-free turbine tool is not included with this model. 6 month warranty from Dyson followed by a 2 1/2 year warranty from ABC Vacuum.
