Work great for my projectThis is excellent for light pressure cleaning.Not effective on auto carpets.Grungy boat cockpit is what I bought it for, and it worked awesome!...but tried it on a dirty carpet...too soft..which is advertisedGreat look, perfect fit, delivered 2 days prior to stated date. Damn, what could be better.There is no possible way to measure this and get even close to to 6-1/2”. The widest part of the plastic body, which is wider that the brush itself, doesn’t even measure 5”!! Where do they get off saying & advertising 6-1/2”?? The brush is decent enough and if it wasn’t for the ridiculous size discrepancy I would given it 5 stars. They are just blatantly lying.Use this to clean the tires of my vehiclesI bought this to wax the non skid in my boat. It has saved me a ton of time on boat clean up. Taking friends and my kids and their friends out fishing they make a mess of the deck and some things don't clean up easily. After waxing the Non-skid everything washes off with ease. Shoe marks, fish blood, bait mung and food wash right out. The wax does not last very long three maybe four trips and you should reapply to keep the cleanup easy.Bought this to clean the anti slip on my boat. Ran it at a slow speed with a non chlorine based cleaner. Between the two they got all the grime out of the gaps without damaging the fiberglass. It is soft yet still cleans. I ran this on a PorterCable random orbitalI will buy another when this wears out.I have not tried the brush yet but when opening the package I found the screw loose inside. It appears the cover holding it inside the brush broke off. There appears to be no sign of the missing cover inside the packaging so I can only assume it was purposely shipped that way. I’m giving this a 3 star review since the brush appears to be what I expected with the minor annoyance that I’ll have to glue the screw inside to make it easier to assemble and keep the part with the brush.Made everything I had to do to prerpare my non skid surface, take off the backing plate and than realized the bolt attachement to attach the brush to the polisher was missing. On the pictures, it’s clearely included. Very very very annoying and I’m very disapointed with it... I lost a lot of time, will have to re-deap clean my non skid to do it with the raplcement oneNot happy at all.VERY DISAPPOINTED.THE PRODUCT CLEARLY HAS THE THREADED ADAPTOR INCLUDED IN THE PHOTOS ON AMAZON.THE PHOTOS OF THE PRODUCT ARE CLEARLY MISLEADINGIT CAN NOT BE USED WITHOUT THE ADAPTORIT WILL BE RETURNEDEs de cerdas algo suaves y es difícil de retirar de la pulidora por ese motivo casi no lo usoUn producto excellenteGood brush..but..screw top has limited fit ups.
