Aquatic All-Purpose Cleaning Brush Set - Medium Stiffness Blue Brushes - Long Reach Extension Attachment Kit - Aquarium Cleaning Products - Fish Tank Cleaner Brushes - Boat Scrub Brush - Hull Scrubber

Even on surfaces that look clean this product will scrub off dirt, soap scum, and grime that you can't even see until you rinse. Great way to prep surface for regular sealing. If you use the drill on high speed it can be a little hard to control with the large flat brush ... you'll need to use both hands. A large shower only took about 15 minutes to thoroughly clean.

Purchased several different sets. Bought these for a myriad of different cleaning purposes - from cleaning wheels to my grill grates. Seem to be higher quality than the rest of the kits available on Amazon. Would buy again.

Use for cleaning shower. Works well. I don’t really use the circular one though

I really liked these brushes and they are well made

I use these for car detailing and they are excellent. The longer cone brush is perfect for cleaning cup holders and underneath seats and hard to reach places. The bristles are hard enough but not too hard for cleaning carpeting and other surfaces in my car. I'll probably go with the white brushes in the future because they are even softer. But these are fine and I used them everyday.

I used these on my shower to remove soap scum. It did remove some but not a lot of it. I was disappointed about that. I gave it a three star because it does a good job on the toilets, and floors. Each brush held up well. If you have caked on soap scum due to hardwater, this doesn't work well. If you don't have hardwater/calcium issues it will do a good job.

I never get to use it my wife loves this device for cleaning the sink tub other random items.

Tried these brushes to clean my tub and my gas stovetop. Worked really well to clean the stove with the smallest brush. Got up baked in areas that I could get before. Used the large flat brush for the tub and it helped some but not fully. I think it is more of a cleaning solution problem than a brush problem though. Only negative I will give so far is the extension piece is subpar with sloppy fitment. Wanted it to help make sure I didn't get my drill wet but the slop will wear you wrists out quickly. Didn't have any issue with just the brush just had to be somewhat careful.
