Review on ProTeam 100147: 14 Inch Scalloped Medium Pile - An Efficient Cleaning Powerhouse by Michael Sharp

I purchased this item in September 2017 to replace a similar attachment on my ProTeam backpack vacuum which I use daily at our office cleaning shop. I started using it in January 2018. Today, 05/19/19, I took a picture of how it was consumed. The front comb is completely worn, the rear is not. It has to do with the tilt position, if you're pulling or pushing it toward the floor, carpet, or whatever. I guess that's what the life I'm going to deal with will serve. Anyway, since I have yet to buy a replacement for it, I'm going to make sure that this item isn't that expensive (about $5 for 5 1/2 months). I'm hoping the scallop is more durable or just available separately for front or back replacement so the replacement will be cheaper(?). 2 stars for that. 😩
