You wash the sweatshirt and it comes out still wearing the dog. Hair in a wash does not rinse away, it moves. One furry pair of pants goes in and the whole load comes out furred, and you finish the job by hand with a lint roller.

Start with the rating, because it is why this one gets explained instead of recommended. Three and a half stars from more than sixty one thousand people. That is the lowest rating on this shelf. It is still here anyway, so here is the honest version.

It rides in the wash with your clothes. Hair that comes off the fabric collects on it instead of staying in the load. It does not plug in. You get two of them. That is the entire mechanism, and it is the entire claim.

The thing it beats is the lint roller, and it beats it on labor, not on results. A roller works one garment at a time, after the wash, with you as the machine. This works on the whole load while the load is already running. If your problem is one jacket on the way out the door, keep the roller. It is faster.

The limit is in the number. Three and a half stars across that many people means a large share of them did not get what they wanted from it. Buy it expecting less hair, not no hair. And it is a laundry product and nothing else: the couch, the bed and the car seat are still yours, and that is where the next load of hair comes from.

So do not buy it to solve pet hair. Buy it to make one load at a time less furry, and only if it actually goes in with the wash every time. It counts on the days it is in the machine and does nothing on the days it stays in the drawer.
