Description from Dyson
DC44 Animal has a detachable long-reach wand, which is balanced for floor to ceiling cleaning. The motorized floor tool has twice the power of the DC35 floor tool, to drive the bristles deeper into the carpet pile with more force. It attaches to the wand or directly to the machine for cleaning awkward spaces. The brush bar has carbon fiber filaments for removing fine dust from hard floors. DC44 Animal has a run time of 20 minutes or 8 minutes on Boost mode. Powered by the Dyson digital motor, DC44 Animal has a fade-free nickel manganese cobalt battery and Root Cyclone™ technology for constant, powerful suction.
