Shark Clean & Empty Cordless Handstick Vacuum with Auto-Empty System - White/Navy (BU3521) is rated 4.7 out of 5 by 35.
Rated 4 out of 5 by from Would recommend! Great vacuum... Easy to use, very comfortable to hold. Good to maneuver and has good suction. The self emptying function is a winner. Great for our little house but does need charging regularly and would struggle to do the whole house in 1 go. Would definitely recommend for the price though!

Rated 5 out of 5 by from Best decision I can't believe it to me so long to buy this? It's light, it's easy, doesn't 'sound' like it's super powerful yet picks everything up with ease, I have pets so vacuum everyday with this and it does my whole 3x1 house on one charge. I have stairs and this makes it so quick and easy to vacuum each step. Getting under cabinets and tables is amazing. And the self empty feature...I always thought this was a bit gimmicky but I'm SOLD! My advice would be to buy it.

Rated 5 out of 5 by from Makes vacuuming a BREEZE !! Makes vacuuming and maintenance a breeze!! I struggle badly with allergies and live in a one bedroom home. This has made vacuuming a breeze, and not having to empty it is a treat, and means I don’t get allergy symptoms when vacuuming. I have been vacuuming almost every day since I got it because it’s so fast and easy. Absolutely love and recommend. Not sure how long charge lasts, I only need it for about Qo minutes at a time :)

Rated 5 out of 5 by from Quality stick vacuum that won't break your bank We had a d***n brand vacuum before but it was getting old so it was time to buy a new one. We thought we'd give the Shark Clean and Empty Stick Vacuum a try. It works wonderfully - sucks up dirt quite well and then it empties itself. Magic! Most of all, it's 1/3 the price of the one we had before. Extremely pleased with our purchase. Definitely highly recommended!

Rated 5 out of 5 by from Perfect, one go machine! Absolutely love this vacuum! Does the whole house in one go & the self clean is amazing. Has a "night" feature which stops the seelfclean function, until turned off. Compact and perfect for my somewhat small landry. & i love that the motor automatically sensors hard floors and carpet. Once moved from hard floors it automatically switches to turbo.

Rated 5 out of 5 by from Amazing vacuum you will enjoy cleaning again. Love it that much that I actually enjoy vacuuming. Its so easy to set up and use, i really do like the way it emptys by itself and dont have to empty the basket eveytime like other brands. It powerful and picks up everything.
