The Dyson Ball Multi-Floor upright is equipped with Dyson Ball technology, this upright vacuum cleaner sits on a ball for easy twisting and turning around furniture and obstacles. Dyson ball technology is exclusive to Dyson vacuums. This version is excellent for pet hair with 245 airwatts of suction. The cleaner head on the Multi-Floor vacuum self-adjusts from carpet to hard floors, which gives you more suction power, and is truly a multi-floor vacuum. The Dyson Multi-Floor uses Dyson’s latest Radial Root Cyclone™ Technology to increase suction power and trap more dirt and dust. The motorized brush bar makes this model ideal for removing pet hair. For delicate rugs and hard floors, the brush bar can be turned off. Dyson’s new lightweight upright ball vacuum is ideal for those who want a powerful vacuum that doesn’t lose suction, but also don’t want to have to work with a heavy floor-cleaning machine.
