New Dyson 17418-01 DC25 The Ball Animal All-Floor Upright Bagless Vacuum Cleaner Dyson DC25 Animal Ball-Technology Upright Vacuum Cleaner | Purple Conventional vacuums rely on bags to trap dust and dirt. But when you start to use some bagged machines, dust can clog the tiny holes in the bag. Some ordinary bagless vacuums work in a similar way. They use a central filter to trap fine dust, which can clog too. Suction drops, leaving dust and dirt behind in your home. Dyson's patented Root Cyclone technology doesn't rely on a bag to trap dust and dirt. Instead, it spins the air so fast that centrifugal forces up to 100,000 times the force of gravity fling dust and dirt out of the air and straight into the clear bin. And that includes the fine dust that can restrict airflow in some ordinary bagless vacuums. Unlike some other vacuums, Dyson machines don't lose suction. Conventional upright vacuums ride on fixed wheels. But they can make you work a lot harder than needed, with all that back and forth around corners and obstacles. Dyson Ball vacuums ride on a ball, which pivots on itself so you can instantly change direction with just a turn of the wrist. Ordinary vacuums can't always retain all the dust they remove - so some of them vent some of it back into your room in the air they expel. That's the reason for the dusty, electrical smell. Dyson cyclones can capture microscopic particles such as pollen, mold and bacteria.
