SPARTA Blue Plastic Grout Brush, Triangle-Shaped Scrub Brush with Scraper for Cleaning Tiles and Grout, 9 x 7 x 7 Inches...

But it should have come with its own pole. It kept unscrewing from the broom handle I used.

Good price and quality.

Product: Sparta Polyester Tile and Grout Brush 9 Inches White (Pack of 4) The brush end is almost as long as broom and the width of the bristles may be slightly thicker than that of a broom. The bristles are flat cut flat, so basically, it's too wide and flat cut to actually get into the grout or corners. Bristles are very stiff so good as a general scrub brush. It does have a screw-in spot to put a broom handle in. I think this is more likely for industrial type use because it was difficult to use in our house on floors or bathroom grout/tile. Sad 'cause there are 4 in a pack!

This is super handy! When I ordered it I thought it was hand-held only but no, it has holes for you to screw in a handle making this extremely useful, especially to clean hard to reach grout that goes from floor to celling in my master shower that has 18' walls. The bristles are stiff and really get in there for scrubbing. They are also long enough to get into corners and hard to reach spots. With the 4 pack you get one for every need.

The actual bristle area covers just under 9 inches by 1 inch and when new are stiff and cut through the grime without too much use of force. I hopefully the life of the bristles lasts for a reasonable amount of time. Surprisingly it weighs quite a bit at 11 ounces. Unless it's a small area, using it handheld may get exhausting quite fast. It is much better and more comfortable with a threaded handle.
