    Great and handy for main floor cleanup

    [Employee of bestbuy] This vaccuum is lightweight but capable. The self emptying dock is awesome and functional. The smart sense in the vaccuum head actually works and changes the motor speed / force when switching from our hard floors to the carpet in the office. The battery more than lasts for a conplete sweep of the main floor (roughly 1000sq ft) and only goes down about 20%. We have three dogs that love to play outside and, frankly, bring the outside inside. It handles it all.

    Amazing!

    This vacuum exceeded all expectations. We have a fluffy dog part german shepherd and the amount of fur is crazy. This vacuum gets used 2 to 3 times daily. Flat surfaces it will run longer. When Ivacuum carpet its about 15 minutes of solid vacuuming before battery runs down. Tile and lvp floors it will run 20 to 25 minutes. Literally the only down side to this vacuum is a design flaws that most have complained about in other reviews. Inside the dirt/dust collector is a wierd plastic piece that small micro dust gets collected in. Especially sand. (Because Florida) Well thats great if you could empty the small section. Its trapped. One way in and no way out. Ive had the vacuum almost a year and that small plastic pocket is still full, no way to empty. It doesnt hurt the overall functionality its just annoying and an eyesore. Overall even with this known issue this vacuum has been a lifesaver. This was purchased to use as a lightweight mobile alternative after a surgery.

    Super Shark

    Very light weight and glides super easily. I love the fact that there are 3 different speeds and there's no need to change settings for different floors. The vacuum senses when vacuuming carpet and hard flooring automatically.

    Good, but weird design choice

    The vacuum functions really well, and i have no complaints about it or the empty system. However, there is a really odd feature in the cannister that catches dust and dirt. However, there is no way to empty this and clean it out. You just have a permanent and annoying monument to the vacuuming you've done. Still recommend, but this design choice has me questioning that.

    Lightweight, gets under furniture easy

    Hair doesnt get stuck so much like the previous shark vacuum. I still keep the previous shark as a back up and for certain accessories this one didnt come with. Like an extended tube attachment for vacuuming the car, corners, or other areas a but difficult to reach. Its still too early to say if i like it better than my old one but i am certainly enjoying some of the new features like auto clean ejection and im still learning how to use it. Charging is different. Instead of 2 battery packs charging by a cable you just have a little station you set it into and it charges instantly. Overall good for a small house. Clean my carpet really good at getting the dust out
