A super handheld vac for small pickups and spots, the Dyson 31 uses Dyson's patented Root Cyclone technology. The highly efficient small and powerful Dyson digital motor does, in fact, create a mini cyclone of considerable power, designed to prevent loss of suction resulting from clogging of the bags and filters. The motor's 3-D impeller spins at speeds up to 104,000 rpm, creating a powerful centrifugal force that separates the dust and dirt from the air and shoots it into the dust bin. It also handles the fine dust that clogs the filter in other bagless vacuums. The Dyson 31 holds a clear debris bin so you can see when it's getting full. The bin is easy to empty—no touching the dirt. Two power modes offer either 10 minutes of standard running time or six minutes at stronger suction for lifting ground-in dirt.
