Does catch hair.  Live in a household with 2 women and the tub was getting clogged.  Trust me you would rather use this then pay a plumber. It doesn't really seal to the tub but it does work!

Had to replace our other one hat finally wore out from 2 dogs and 6 years. We have 2 short hair dogs and the hair just flies off with this. Keeps our house from being covered in tiny hairs.

Catches hair great. Makes water backup just a little bit.

It literally catches every single hair you throw at it, and doesn't let anything down the drain. A couple of downsides: when it gets too full of hair, water can't really get through, so you need to be diligent and wipe out the hair at least once a week (it's mostly my wife's hair in mine). Additionally, it gets a little grimy after a few months, but I found that soaking it overnight in a bleach solution removed all the grime easily. Highly recommend, it works wonders!

Works for my five year old and my adult
Brother. Still hair gets everywhere but at least not on my kids back/shoulders which is the reason I got it. He likes it a lot more.

I have bought this product two separate times ( a few years apart ), and each time it seems to do a GREAT job catching moths  and fruit flies, but doesn't seem to attract many house flies. We have placed them strategically around our kitchen area with not much luck. It comes with a push pin inside to mount to the ceiling which is nice.

Works great. I just placed it over the tub drain and mechanical drain plug.  It catches hair like crazy and is easy to clean!

The Hoky Sweeper works great for quick pick-ups, including cat and dog hair.  I had a similar one years ago and it works just as well as that one.

The Eureka vacuum is compact, light-weight and has good suction. I have long brown hair that constantly falls out - in the bathroom and throughout our studio apartment (with hard wood floors). We moved in 1 month ago and have been using a dustpan to sweep all the hair and dust. No more brush tangled with my hair! The Eureka vacuum sucks up my hair without a problem. It is perfect for our small place and it contracts down to a toy-sized vacuum cleaner. The only downside is that it is pretty loud for such a small thing so no vacuuming at night.

Works great...but a little too great...it picks up EVERYTHING in my house. fan on in the living room? picks it up. Front door opening while in a bedroom with the door closed? picks it up. If you have a PERFECTLY sound proof room its great but don't move at all itll pick up any fabric ruffling

I love the TubShroom! I've always "shed" a lot when I wash my hair* and have clogged many a shower/tub drain in my day. I've tried a number of different over-the-drain hair-catchers over the years. But they all get gross quickly and still let a lot of hair through. The last one I had collected so much shampoo and soap residue that it became clogged and we were soon standing in a few inches of water during short showers.

The TubShroom catches the hair as advertised. And it's almost as easy to pull the hair off at the end of my shower as the videos show. There is some residue that collects so I should be doing more regular wiping down than I have been, but it seems like that will come off easily too.

My biggest complaint** is that my dog thinks the TubShroom is a chew toy. So she'll occasionally jump into the tub and pull it out to play with when she doesn't think she's getting enough attention. She bit off (but did not swallow) a piece of the first one we got, so it no longer fit securely in the drain. So we reordered and got an extra this time. Hopefully we'll keep her from chewing it apart again, but we're prepared just in case we need it!

*My completely non-scientific theory for why I "shed" so much more in the shower and less around the house than the other women I've lived with my hairs "fall out" all day long just like everyone else. But they are held in place by the gel to style my curls and somewhat by the curls themselves. So it's not until I wash the product out and finger-comb my hair that the hairs are released and free to fall to the floor.

**Not something they can actually fix!

Picks up all my cat hair, all the dust and the food outside of their bowl. It does get very loud but that's not really a problem to me. It is a bit fat but it's still compact, i keep it in my closet. It picks up most hairs but there's some that needs some help to get unstuck, that's where the red mount comes in. It has little rubber things that help those hairs get loose once you brush it.

Our dog sheds a lot.  Bob goes under our furniture and cleans up the dog hair so it keeps the house much tidier because there is less hair that moves around between cleanings.  Love that I can set Bob to goes off on his own even when I am not home. It has a dust bin big enough to pick up all the dog hair in our entire house in one sweep thru.  Other products need to be emptied multiple times during their cleaning cycle.

I have a ragdoll cat that his hair normally floats everywhere...this brush traps the hair and does not allow it to fly all over the house...plus he loves it!!!

This didn't work well any way I've tried picks up some hair but not much. Is there a secret to it?

Awesome way for a pet owner like myself to prevent buildup of dog hair mountains and other dust bunnies.  Not a full replacement for a regular vacuum, but the Roomba is very good at picking up hair, dust, debris and other small particles. Just remember to empty the canister after each cleaning, and regularly inspect (and clean when necessary) the brushes and filter. Love coming home to a clean(er) apartment after letting Roomba do its thing!

We have three feline fur-children and one canine fur-child, and they all shed like their main purpose in life is to cover the furniture with fur.  After lots of research on many different sites, including Amazon, I decided to get this vacuum (mainly for pet hair, but also because toddlers = crushed goldfish crackers if you're not careful).

It's a bit louder and whinier than I was expecting, but HOLY COW does it pick up fur!  I was shocked (and slightly grossed out) by the fur it picked up off our duvet cover, which we keep covered with ANOTHER blanket precisely to reduce the fur balls that the furrballs leave behind.  (So much for that solution.)

It's also great at handling the random messes kids leave around, such as the aforementioned cracker crumbs.

We'll be keeping this one around for a while.
