The Dyson Ball Animal 2 is widely regarded as the best Dyson model for pets thanks to its high suction power (270 airwatts), lifetime washable HEPA filter and dedicated pet hair attachments. The Big Ball Multi Floor 2 is a lighter, less powerful alternative (245 airwatts), but is still effective on hard floors and thin carpets.

Compared with the Miele Cat & Dog (including the Miele Dynamic U1 Cat & Dog and the Miele Complete C3 Cat & Dog), the Dyson Animal 2 is lighter, bagless, has a washable HEPA filter and offers high suction power for pet hair. The Miele, on the other hand, is a heavier, bagged hoover, with better allergen filtration thanks to the bag, but without a traditional HEPA filter, and better manoeuvrability in cluttered spaces. The Miele is also renowned for its robustness and efficiency on hard floors and thick carpets, thanks to a height-adjustable suction head and a power adjustment system.

In short, for pet hair:

- Dyson Ball Animal 2: better suction power, washable HEPA filter, bagless, lighter, pet accessories.
- Miele Cat & Dog: hoover with bag, better allergen filtration, heavier, easier to handle in cluttered spaces, adjustable suction head, robust.

The Big Ball Multi Floor 2 is a more compact and less powerful version of the Animal 2, so less optimised for pet hair, but still effective for general use.
