A Must-Have Cleaning Tool!
This grout scrub brush has quickly become one of my favorite cleaning tools in the house! The long handle makes it so easy to scrub floors and shower tiles without bending or straining my back. The bristles are stiff enough to really get into the grout and lift dirt, but they don’t damage the tile. I’ve used it on my bathroom floors, shower, and even other tough spots around the house and it works amazing every time. It makes deep cleaning feel so much easier and faster. If you’re serious about keeping your home spotless, this brush is definitely worth it. Highly recommend!

Good size
I bought this to get in between the wall and appliances in the laundry room. Perfect fit. Very firm bristles and seems durable. Easy to use and hang up. I’d buy it again

Good shower/tub scrubber
Easy to put together and cleans well. However, leaks brown water from the joints.

Didn't expect it to be this good
The brush was easy to put together. The head swivels, which I like and I have other cleaning tools that swivel as well. It is not a fixed head, which is good when you need to get into tight places at different angles. The unit was completely sturdy. No breaks, no missing pieces. I had no problem whatsoever with the way it was made and the way it was put together. Be aware that this is a very stiff brush. The bristles feel like metal, so don't use it on surfaces that can scratch. If you do want to use it on painted surfaces, like baseboards, try wrapping it in a microfiber cloth to clean. Then test in a hidden area first to make sure the bristles don't go through the microfiber and scratch up the paint. I have both ceramic and porcelain tile in my bathroom and the white grout has been looking pretty sad for a while, despite cleaning one-by-one with bleach and magic erasers every few weeks. It used to take hours to clean the tiles and all of the grout between the tiles. When done, some of them looked better and some didn't. I filled up a bucket with hot water and added some Dawn Powerwash spray, which is a great grease-cutting detergent with added alcohol (probably isopropyl). If you don't have that product, add some good grease-cutting dish soap and with a bit of isopropyl alcohol, which is very cheap. There are "recipes" online that you can use for measurements. Then I dipped the brush in and started working it up and down the shower walls, focusing as much as possible on the grout lines. I did a quick wipe with a damp microfiber cloth to make sure the scum was completely gone off of the tiles. If I could still feel soap scum in those spaces where it tends to collect, I went over it again. Then I rinsed the walls by aiming the showerhead at them as much as possible. If you didn't overdo the soap, a quick wipe with damp microfiber should do the trick. Or, let it air dry and see how it turns out. If it's streaky, just go over with a damp microfiber, rinsing occasionally. For the shower floor, I sprinkled Comet with bleach on the damp shower floor, because it's tougher to get the white floor to look clean. Then I let it sit for while and took a break. When I returned, I wet the floor, then scrubbed with the brush and rinsed. No more hands and knees! Yay! After everything was rinsed and dried, this was the cleanest my shower looked in a long time. It took less time, which meant I could focus more effort on cleaning the fixtures and the bottles of body wash and shampoo. It all came together beautifully. It was clean, fresh, and shining after it was done. I almost can't wait for the next cleaning. :-) Ok, that might be a bit of an exaggeration, but I don't hate it as much as previously. I let the brush dry completely and took it apart and stored it back in the box. It takes up very little room and I don't have a lot of storage space for full-sized cleaning implements. Putting it back in the box and then into the closet worked well for me.

Tile floor looks like new!
This brush is excellent! Using it on grout between floor tiles and it works like a dream. I have light grey grout and it cleans up perfectly. Spray with your regular cleaner, let it sit for a minute and scrub away. Sturdy bristles and Amazing!

AMAZING FAST results and very DURABLE + 3rd Trimester pregnancy proof!
I am obsessed with this new cleaning tool! We have stubborn floors with grooves and ridges in them that have been needing a good scrub that a mop simply wont fix. Ive gotten on my hands and knees scrubbing with other products and sponges and ended up with back pain, wrist pain, and arm pain . This scrubber is amazing and i have had 0 aches or pains from cleaning since using it. I am in my third trimester of pregnancy with body pains here and there and back pain. However, when im scrubbing the floors, there is a knob that moves with the bristles, so no matter which way you hold it, it scrubs! And it cleans well. The bristles are hard, rough and durable which is perfect for removing tough stains and getting the hard areas. I love this! I hope it lasts me a long time.

Better if your grout is almost flush
This is a well-made product and addresses a need, but didn’t do the job for me. The bristles are stiff as they should be and tapered at the ends, but my new shower stall (rental) has smaller tiles varied in size and the grout is lower than it should be for this to be effective cleaning grout. I missed the return date as my move was delayed. I’m going to try using it on my balcony (occasional bird droppings). I think it would also be fine for patio tiles. The recommendation to purchase came from a housekeeper. Didn’t work for me, but maybe with a different tile grout ratio.

Excellent grout scrubber
This is what I have needed. Worked like a dream! And I didn’t get blisters thanks to the cushioned handle.
