Fur on the rug and fur on the stairs: one vacuum rarely wins both. Rugs get the Shark Rotator Pet Upright, daily floors the Roborock Q7 L5, and the couch, stairs and car the BISSELL Pet Hair Eraser.
Head to head, need by need
Heavy shedder: Shark on carpet, Roborock on hard floors
The Shark has a self-cleaning brushroll built for pet hair with no hair wrap, so long fur doesn't wrap the roll. The Roborock pairs 8,000 Pa suction with dual anti-tangle brushes and runs daily, before the hair piles up. Carpet-heavy home: Shark. Mostly hard floors: Roborock.
Stairs and the car: BISSELL wins
Cordless, with a rubber nozzle made for pet hair on upholstery, so it goes up the stairs and out to the back seat. The Shark is a corded upright, heavier to carry upstairs. The Roborock stays on its floor.
Small apartment: Roborock plus BISSELL
A daily Roborock run keeps the floor clear, and the BISSELL takes the couch and bed. You skip the upright.
Rug: Shark wins
The Shark is made for carpet in heavy-shedding homes, with a sealed system and HEPA filter. The Roborock handles carpet too, but a rug that holds fur is the upright's job. The BISSELL is not for floors.
Rugs and carpet: Shark. Daily floor hair: Roborock. Couch, stairs, car: BISSELL. Heavy shedder with a couch: Roborock or Shark, plus the BISSELL.
