I am not being paid for this review at all!!! 
I have always used shark products. I read some of the reviews on different websites about this vacuum and was skeptical about buying it at first. Boy am I glad that I ignored the reviews I read. I absolutely love this vacuum. I’ve had it now for 5 months. The hair really doesn’t tangle on the brush at all. I have 1 long haired dog, 1 short haired dog, my hair is pass the middle of my back and same with my daughters hair. I am constantly losing hair. I have had problems with past vacuums with the hair staying on the brush but with this one I haven’t. Read the instructions on how to operate the vacuum and you shouldn’t have any problems whatsoever!!! I HIGHLY RECOMMEND THIS VACUUM
