A:Answer Hi there, this is Kelly with Dyson. The Dyson V11™ Animal vacuum has an integrated digital motor which spins the brush bar up to 60 times a second. It drives stiff nylon bristles deep into carpet to remove dirt, and carbon fiber filaments capture fine dust on hard floors. Both machines offer three cleaning modes for a variety of household tasks, so you'll have the right balance of power and run time where you need it. This model also has an LED display and will allow you to switch between your 3 power modes: Eco, Auto and Boost. The V11™ Outsize comes with a full-size cleanerhead and a larger dust bin. Having a shedding dog, you might find greater benefit to having that larger size bin; it would for sure mean less emptying for you.
Best wishes,
Kelly
