I tested these pet hair vacuums for a week if not more (I’ve been using both the Dyson cordless and handheld for months now), and I’ve used them on nearly every surface in my house—including the cat trees and behind my two cats’ litter box. When testing began, I lived in a large house with three cats and a dog (more hair in a larger area), and for the latter half of testing, I lived with two cats in a small apartment (slightly less hair in a smaller area with less places for hair to hide).

I also tested every attachment on problem areas like carpeted stairs, crevices of air vents, a high-pile rug, and hardwood floors. Not all pet hair vacuums are created alike, and they vary quite a bit in their effectiveness on different surfaces and with different attachments. I set these up, charged ’em, and vacuumed with them until they died, noting run time, power, effectiveness, and ease of emptying the bin and cleaning the filter.

It seems like a lot of brands will slap the words “pet hair” onto a product and market it as such without really specifying why or how it’s effective for pet hair. Of course, I tested those to see if they put their metaphorical vac mouths where their money was. On the flip side, I also tested some that were well rated for overall efficacy but not marketed toward pets—like the Roborock Saros 10R, a pricey robovac that uses AI mapping and can identify pets nearby and quiet its motor.

Speaking of, vacuums and pets are inherently antithetical. Vacuums are a necessary evil to combat pet hair, but your pets will likely be scared of them. If my cat Basil had opposable thumbs, I know he’d be leaving hate comments on this article. Aside from the robovac picks (which for some reason my cats don’t mind), my cat Basil had a mild cardiac event each time I tested the other vacs on this list. So along with effectiveness and suction, I also took into consideration loudness, as well as how easy the product is to handle.

Generally though, when shopping for a pet hair vacuum, look for suction power, bin capacity, attachments, and type of bristle or motor bar—figure out what’s going to be doing the actual picking up of dust, dander, and pet hair. I found that conical bars like the ones on certain Dyson models work well to not get tangled, and dual brushes like on the Ryobi work together to effectively pick up more. Also read reviews from real people with real, furry pets, but know that no two pets are alike. Take into consideration what kind of shedder you live with, and what type of space needs cleaning; a robovac may not be best for a house with multiple flights of carpeted stairs.
