The best robot vacuums for pet hair, ranked by specs

Loose fur on hard floors is easy for any robot. The real test is hair worked into carpet pile and upholstery edges — that takes lift, and lift is what the pascal (Pa) rating measures. In our tracked set the spread is huge: from 5,000 Pa to 25,000 Pa.

As a rule of thumb from our data: under ~4,000 Pa is hard-floor territory, 4,000–8,000 Pa handles low-pile carpet and moderate shedding, and 8,000+ Pa is where embedded pet hair in medium-pile carpet starts to come out reliably.

• Shedding season changes the math — a bin that lasts a week in July can fill daily in spring.
• Suction also drives edges and corners, where fur drifts and collects.
• Brush-roll design still matters — see each model's product page for owner-reported hair wrap.

Pet hair compacts poorly and fills a robot's onboard dustbin two to three times faster than ordinary dust. A self-emptying dock turns daily bin trips into a monthly bag swap — in our set, the models flagged “Yes” in the self-empty column are the ones to shortlist.

Two pet-critical behaviors don't appear in any spec table: obstacle avoidance for pet accidents, and how much hair wraps around the brush roll. Both are camera/software and brush-design questions, not suction questions — so we don't score them. The owner-review counts on each product page are the best public signal we have.
