The only vacuum with no filters to wash or replace. Strong suction. With extra tools.Dyson Cinetic tips oscillate at up to 5,000 Hz, separating the microscopic dust that clogs all other vacuums. Other manufacturers make big, bold claims about their vacuums never losing suction, but the reality is they do. They can't generate centrifugal forces high enough to separate the smaller particles of dust and dirt. Instead, they rely on filters to capture these particles. However, dust quickly builds up on these filters, clogging the pores and blocking the airflow - causing the vacuum to lose suction. Even regularly washing the filter can't remove all the dust. So no matter what they say, all other vacuums will lose suction. The Dyson Cinetic Big Ball vacuum, on the other hand, is the only vacuum that doesn't lose suction. And that's because Dyson Cinetic science has revolutionized vacuum cleaner technology - it captures the microscopic dust that clogs all others. Dyson Cinetic tips oscillate at up to 5,000 Hz, separating the microscopic dust that clogs all other vacuums, and preventing dust building up and blocking the airflow. In fact, dust separation is so efficient that there's no need for a pre-motor filter, so it doesn't lose suction.No dirty filters to wash or replace. The only vacuum with no filters to wash or replace, so there's no loss of suction. Dust separation in vacuums containing Dyson Cinetic science is so efficient that there are no dirty filters to wash or replace.Self-adjusting cleaner head Seals in suction across carpets and hard floors. The motorized brush bar with stiff nylon bristles drives deep into carpet to remove ground-in dirt. An active base plate automatically adjusts the cleaner head height to seal in suction across carpets and hard floors. This ensures that even the microscopic particles between floorboards are sucked up into the vacuum. The motorized brush bar with stiff nylon bristles drives deep into carpet to remove ground-in dirt.Ball technology. Steers easily into difficult places with a simple turn of the wrist. Ball technology - a dynamic turning circle. Fixed wheels are not designed to turn corners. But a ball can turn on the spot. As the ball's axis is tilted, its turning circle tightens - allowing full and accurate steering control. The vacuum's key components have been engineered to fit inside the ball itself. This gives the machine a streamlined profile, allowing access to tight spaces and lowering its center of gravity to make it lighter in the hand.Designed for homes with pets. Tangle-free Turbine tool removes hair from carpets and upholstery. The Tangle-free Turbine tool is the only turbine tool that doesn't tangle. Counter-rotating heads with brushes remove hair from carpets and upholstery, so there's no brush bar for hair to wrap around. The flexible heads bend to maintain contact across uneven surfaces, and they're positioned so that the brushes reach to the front and sides of the tool - drawing hair and dirt in from all directions. Whole-machine HEPA filtration ensures that allergens are trapped inside the machine, not expelled back into the home.Carbon fiber soft dusting brush—Ultra-fine carbon fiber filaments improve pick-up of fine dust from hard surfaces. Its thin profile fits into small crevices and an angled handle makes it easy to use.Reach under tool—A paddle-shaped profile, robust bristles and flexible construction enable dust and dirt removal from the most hard-to-reach parts of your home.Multi-angle brush. Twists into different positions and angles for easy high-reach cleaning. The Dyson Multi-angle brush twists to give multiple angles to remove dust, dirt and allergens from hard to reach surfaces such as cupboard tops, door frames and lampshades.
