75mm Diameter Stainless Steel Cylinder Wire Tube Pipe Cleaning Brush 1Pc

I purchased this brush to clean the underside of my mower. It seemed to be working very well as you can see in the picture of the mower but after about 20 seconds I noticed bristles flying out all over the place. It appears that the twisted helix body of the brush was unwinding and losing its grip on the bristles, which then fell out. Maybe the seller would say the brush is not meant to be used in a drill but there is nothing about this in the product listing. Also, I asked a question before purchasing to see if there was an extension I could use with my drill. The seller said no but did not say anything about not using it in a drill.
