Short answer: for pet hair, look for an anti-tangle brush roll, at least 30kPa of suction, a filter that traps fine dander, and a handheld mode for couches and pet beds. Everything else is a nice-to-have.
1. An anti-tangle brush roll
Long pet hair wraps around ordinary brush rolls and has to be cut off with scissors. Anti-tangle rollers are designed so hair slides off and into the bin instead. This matters more than any other feature if you have a shedding dog or a long-haired cat.
2. Enough suction for carpet
Hair on hard floors is easy. Hair worked into carpet and rugs needs stronger suction. Around 30–35kPa handles most homes. If you have thick carpet or a heavy shedder, 50kPa makes a noticeable difference.
3. Filtration that holds onto dander
Pet dander is fine enough to blow back out of a weak filter. A multi-stage or HEPA-style filter keeps it in the bin. Replace or wash the filter every 2 to 3 months, or more often with several pets.
4. A handheld mode
Most pet hair ends up on couches, pet beds, stairs and car seats, not just floors. A stick vacuum that converts to a handheld covers all of them with one battery.

Tips that make any vacuum work better on pet hair
- Empty the bin before it is full. Suction drops as the bin fills.
- Vacuum high-traffic pet areas a few times a week instead of one big weekly clean.
- Keep a spare filter so you can swap one in while the other dries after washing.
