Input:
I purchased  this because of the light weight, I am 80 and have arthritis resulting in shoulder replacement surgery recently.  The problem is; the carpet attachment is impossible to use, I've never seen a carpet attachment like it.  I have carpeted stairs and my high school grand-daughter had a very hard time trying to vacuum it. I would have rated it sooner but only recently got clearance from my Dr. to do house cleaning. I would not recommend this if you are going to use it on carpet.

Options:
A: very positive
B: positive
C: neutral
D: negative
E: very negative
Answer: D: negative
