My in-laws and sister both have dogs who shed everywhere all the time, so I have extensive experience using both of these products at their homes. Here’s a bit about each to help you decide which one might be right for you!
The roller is super quick, cheaper, and more compact than the vacuum (so, good if you have a small space), and easily picks up mountains of hair from couches, chairs, and other upholstered furniture! It does require a little bit of elbow grease in the form of semi-rigorous rolling up and down, as the gif above shows. You open up the back to empty the hair out when you’re done, and it’s ready to reuse, and literally lasts for years, even with daily use. I’d say it takes about four minutes total to pick up all the hair from a regular size couch.

The handheld vacuum is like a turbo-charged upgrade to the roller: all you do is pick it up, turn it on, and run it over the piles of hair to make every last bit vanish! Since it’s a vacuum, it’s bigger and heavier than the roller, but I’m a five-foot-three thirty-something and have no issues using it with just one hand. You’ll probably want a convenient but hidden spot to store it on its charger, which keeps it ready to suck up pet hair at any moment. It has three specialized attachments but the motorized brush head is the key for most upholstery! And like most handheld vacuums, no bags are required; you simply press a button to open the dust compartment and empty it. I can vacuum my in-laws large sectional with this in about two minutes!

TBH, there’s not a bad choice here. Either way you go, you’ll have SO much less pet hair in your life!
