PetPal Gear Score

Whether the brush architecture moves hair off the roller or merely resists wrap. Designs that strip hair into the bin during operation, or route it into the suction path with airflow before it reaches the roller, score highest — the roborock DuoDivide center-inlet mechanism, the Ecovacs BLAST airflow routing, the dreame DuoBrush air duct and iRobot's paired rubber rollers all qualify. Passive tangle-free geometry — a brush described as letting hair pass through without wrapping, such as the eufy DuoSpiral and the X10 Pro-Detangling roller — scores a band lower. Every zero-tangle figure quoted in this guide is manufacturer-reported, including the TÜV SÜD certificate eufy cites and the SGS certificate Roborock cites, so neither certificate lifts a pick out of its mechanism band and this factor weighs mechanism as heavily as claimed numbers.

The catastrophic failure mode of a robot vacuum in a pet home, scored on independent evidence first. Vacuum Wars 2026 obstacle-avoidance results carry the most weight — 24 of 24 for the eufy Omni S2 and 23 of 24 for the Ecovacs T90 Pro Omni. Machines with camera or structured-light sensing but no published score sit in the middle. Units relying on top-mounted LiDAR alone score lowest, because that sensor placement often cannot detect low-profile objects. Manufacturer guarantees are not credited unless they cover the exact model being ranked.

How long the dock runs before a multi-pet household has to intervene, measured against a shedding load rather than a generic one. Stated intervals — up to 90 days on the Roomba, 68 days on the Omni S2, 60 days on the Saros 10R, 7 to 9 weeks on the Q7 M5+ — are discounted because manufacturers measure them under generic conditions and say so. Sealed bag systems score above open bins, and any listing that states no interval at all is scored down for leaving the buyer unable to plan.

Granule and fine-clay handling across hard floor and carpet. The Allergy Standards robotic-vacuum standard sets a lower bar for carpet than for hard floor, at 80% versus 90% removal, which is the same physics that makes tracked litter in carpet pile harder to lift than litter on tile. Machines that vacuum carpet dry before mopping hard floors, lift the mop over carpet, and extend a roller or brush to baseboards score highest here.

Whether captured dander stays captured, weighted against the fact that no pick in this guide appears on the certified registry of the one third-party robot-vacuum allergen standard we could verify. Sealed, odor-controlled bag systems score above open bins because the EPA identifies vacuumed dust escaping back into room air as a real exposure route, and the Allergy Standards program treats receptacle emptying as its own tested failure point. Manufacturer capture percentages are noted but not treated as certified performance.

How tolerable the machine is to a skittish cat or an anxious dog. This is the weakest-evidence factor in the model and is weighted accordingly: none of the eight listings publishes a decibel figure, so scoring rests on stated noise engineering such as dreame's shock absorbers and fluid-dynamic design, or roborock's raised-brush quiet return. Where a maker says nothing about noise, this factor scores neutral rather than poorly.
