So yesterday I noticed that I did leave one thing out on my roller post. Sometimes you’ll see vacuums with the description “Two Brush Agitator”. This can be misleading if you’re not familiar with the terminology. but this does not mean that your vacuum comes with two rollers.
What this fancy wording actually means is that the roller has two rows of bristles on the actual roller, instead of one. It does not mean that your vacuum has two rollers. If you look at the picture, you’ll see that the top one has one row of brushes, as opposed to the bottom two brushes.
There used to be a few vacuums that had a double roller design, but none that I know of right now have this. I believe there were some incidents where the two rollers were getting caught on the same item at the same time, causing some damage to the machine.
For those of you new to my blog, here's the original post.
