The attachment works fine. I made an error and ordered this one rather than one like my original brush which had a metal plate on the bottom. The original one was good for carpet as well as hard floors. I currently have carpeting and plan to replace it with tile flooring. This brush will work very well once I change my flooring to all hard surface flooring.
This brush is OK - not the best I've used before. It glides quietly and easily but I found it missed some crumbs and you have to go back to pick them up. (NOTE: Spreading your suction over 14 inches will reduce effectiveness.)
May cover a better area however I find it leaves dirt behind on hardwood floors. (MD NOTES: 14-inches is wide. If your system doesn't have really good power then this brush is not too effective. Try the 12-inch models.)
I like this fine, however, I wish I had gotten a shorter one. This doesn't fit under some of my furniture.
This brush is larger than the original brush, so I think it does not have the power to vacuum up as well as the smaller brush or maybe the wheels hold it off the floor and it doesn't pickup as well as the smaller brush.
nice width but tends to push stuff arond with the front brush, probably needs greater gaps in front
