Haven't used it yet but it's sturdy and well made. The handle is 5 screw-together pieces and the handle wall thickness is enough to place some serious pressure on the brush head; I believe the the threaded connections may help handle rigidity as well. Since some other reviewers commented about the handle "unscrewing", I placed a drop of "blue" threadlocker on each connection except the brush head and hand-tightened each (with clean hands) as much as I could. The product description of the brush head was vague. "Thick, Durable Bristles" means bristle thickness like a heavy wire brush with much more density (about 3 - 4 more total bristles per area) and the bristle material is synthetic to prevent scratches. "angled" means the bristles are cut at an angle on each side of the head to form a "V" lengthwise in the center - exactly what I was hoping for! Better photos could have helped and right now I don't have an option to post a photo but if I do after the next click, I will!

The brush is very effective for straight-line grout. However, (1) the brush cannot work corners, and (2) the handle loosens easily making retightening a regular nuisance!

Able to clean well

I love this, cut my grout cleaning time in half! So much easier then squatting on floor with a hand brush.The brush head is metal....it reminds me of a pool algae brush, it's full of metal tines. The whole head swivels and tilts so you can use it in any direction.The pole assembles by screwing pieces together. This is not quite perfect as I had to stop to repeatedly tighten various pieces. I am not lowering my rating because I do have arthritic hands and it could just be that I can't tighten them enough to get them to hold. I'd prefer pieces that would snap together.It takes a fluid...water or cleaning product....I had great results with both as it just needs a liquid to raise the dirt up and then I'd use a rag to pick up the water/dirt.I do wish that they'd give you some of small tray the shape of the brush head to use to pick up cleaning water. I tried a bucket but it doesn't fit into a circular shape. I then just poured water onto the floor and that was a mess. So then I got a kitchen food container that was rectangular in shape and that worked.My grout gets cleaned regularly so it didn't take a whole lot of "pushing" or "effort" to get this to work. I'm 65 and don't have much of that anyway, lol.I'm very pleased, much easier.

The media could not be loaded. No more wet sore knees scrubbing grout!!!This new brush it stiff, pointed in the middle, has a flexible head for perfect angle, plenty long for most any height.I like clean grout, but I don’t love scrubbing it but now it’s just not that bad.This brush is plenty stiff to get the job done, I found it easy to first web my floor then scrub so I don’t have to keep dipping it into my water bucket.My grout looks brand new now, and that’s a great feeling:-)

The media could not be loaded. Don’t look to close at my floors:) Slate is so hard to keep clean. I sprayed my grout and let the cleaning solution sit for 20-30 mins. I honestly forgot while I was cooking. This grout tool is easy to use and clean. It’s sturdy. It works!
