The different brushes available allow you to clean in hard to get places. It also saves your arm from muscle cramping. Cleans all different dirty areas from different materials.

I thought these were trash, tore apart after a few minutes of use, but that was because I was using an impact drill, use a regular drill NOT Impact one. Once I switched to a drill the brushes lasted longer than my battery. Was using a Milwaukee M18 Impact Driver, but once I switched to a Milwaukee M18 Drill Worked as described, I could push down as hard as I wanted on the drill and the brush kept spinning and never got hot and tore off from spindle. So use only a drill and not impact driver

Ordered black version. It helps get in small cracks without all the elbow wear and tear. However, with extender it wobbles A LOT. It requires to add a wee bit of pressure to keep it stable. Used it with a shorter extender and worked a wee bit better. It has made cleaning easier though.

I used this and a hands brush b/c some areas needs more pressure and the brush would stop moving if you pushed down hard. But, it did half the work for me.

These work great, my only complaint is they are not abrasive enough to remove tough stuck on stuff, but I am using them to remove thick dust and dirt it works perfectly and is definitely better than a scrub brush and elbow grease. Would buy them again but if you are buying them to remove years of build up these will not do the job they are not abrasive enough.
