The highest suction of any handheld. DC34 delivers 15 minutes of powerful suction – or 6 minutes on MAX power for tackling tougher cleans. It’s powered by the Dyson digital motor, which spins up to 5 times faster than a racing car engine. DC34 has a lithium-ion battery that recharges up to 3 times faster than others, and Dyson’s patented Root Cyclone™ technology for no loss of suction. Root Cyclone™ technology Dyson's patented Root Cyclone™ technology doesn't rely on a bag. 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 vacuum cleaners, Dyson machines don't lose suction. Dyson digital motor Michael Faraday discovered electromagnetic induction, the principle behind the electric motor, in 1831. Yet, despite being technologically advanced at the time, electric motors have changed very little since. Bulky, old-fashioned components and lots of moving parts prone to failure. Dyson engineers spent a decade developing new types of highly efficient digital motors. The Dyson digital motor is smaller, lighter, cleaner and more power-efficient than conventional electric motors. Dyson digital motors use digital pulse technology, spinning at up to 104,000 times a minute (five times faster than a racing car engine). Dual power mode Unique to Dyson, dual power mode gives you two power options. 15 minutes of powerful suction for longer tasks. Or 6 minutes on MAX power for tackling tougher cleans. Lightweight and ergonomic Weighs just 2.9lbs, with balanced weight distribution for easy handling. Hygienic and quick to empty Just push the button to release the dirt. The bin on a Dyson handheld is clear, so you can see when it needs emptying and how much dust and dirt the machine has captured. Lithium-ion battery Releases charge evenly with no drop off. Recharges up to three times faster than others.
