Review on Fast-Cleaning Drill Attachment for Delicate Surfaces – Effortlessly Scrub Fiberglass Tub, Microfiber Upholstery, Automotive Carpet, Boat Seat, Vinyl Floor – 5 Inch Soft White Bristle Diameter by Natasha Williams

I used your brush head with a drill to clean my shower. The bit attached to the brush is screwed on and not permanently fixed. About every five minutes the brush would unscrew itself from the drill and I had to stop and reattach the brush to the drill. To put it mildly, it was annoying. In the end it did a good job but it took so long to finish. I'll glue the bit onto the brush so I don't have this problem I hope. If you're getting these types of complaints, you might want to consider redesigning the brush and head as one piece. Overall, this isn't the worst product I've ever bought, but I won't buy it again, nor will I recommend it to family or friends.
