Absolutely amazing vacuum, light weight in comparison to traditional vacuum. Slow to charge, but charge lasts quite awhile. Daily use in small one bedroom apartment, charge lasts about two weeks. Great attachments, easy to disassemble for cleaning purposes, great suction.

One of the Best Wireless Vacuums You Can Buy
If you’re considering a wireless vacuum cleaner, this is hands down one of the best investments you can make. It delivers powerful performance, especially on carpets, picking up dirt impressively well. The battery life is long enough for practical, everyday cleaning, and the whole unit is lightweight and easy to maneuver. What really stands out is the thoughtful design and ergonomic build — everything feels intuitive and well-balanced. Based on my experience so far, it’s a purchase I feel confident about and would recommend to others.

good quality
The Vacuum cleaners did good job on daily cleaning work. For my flat which is only 369 sqft, it can completely the work in one-time full charge. However, if I want to do extra cleaning, then I need to charge it again. All about this vacuum is good, except the battery is kind insufficient. But if you live alone or having a small apartment then this is the most affordable and valuable vacuum cleaner I recommend.

Don’t waste your time and money
As a user of proper vacuum cleaners I was skeptical about cordless vacuum cleaners. Unfortunately my experience proved true. As soon as I got it I tried to vacuum a strand of hair and wouldn’t come. I felt like I am holding a fan not a vacuum. I tried vacuuming the tiles, I had to go over the piece of crumble four times to pick it up. Then I tried to vacuum my carpet, the vacuum showed red light and shut off and the battery which was full became zero. This is a toy not a vacuum.

Excellent for pet hair
Just received this shark hoover. It is so powerful and picks up everything. It’s easy to use, a little heavier than others I’ve had but I’ll get used to it. Great at picking up dog hair and dust. Highly recommend it.

Great suction but ….
The vacuum is effective and light enough to use easily. It lifts all manner of fur and cat litter. I find that fur collects in the gutters in the vacuum head though and gets trapped in the little rollers on the vacuum head. So it feels that while it’s targeted at pet owners, some important aspects of fur management have been missed.

What I received was an opened box with a used item inside.

I bought this to keep the area around my rat cages clean, because love to kick their bedding (hemp and wood shavings) everywhere, requiring vacuuming at least once a day, and my previous vacuum wasn't keeping up with what it needed to suck. No such trouble with this Shark though! It sucks up hemp chips and wood shavings like a champ! The auto-sense works perfectly and adjusts the power necessary in that area with no issues. It grabs up a lot of pet hair too, just as described. I've attached a video of some excess debris in the middle of a cage-clean today to show how well it goes! It also picks up and filters an insane amount of dust! Looking at my previous vacs, you wouldn't know how much dust was lingering about in carpets, on upholstery, curtains, etc. This Shark gives my air purifier a run for its money as far as dander and dust-filtering goes. The little air pod it came with leaves the air post-vacuum with a nice, fresh sent as well. The folding part of the tube makes for both easy storage, and a cinch for getting under anything that has a 90° angle, which is perfect for someone who has a back condition like me - no more bending and hunching and getting down on the floor! The main head also has a very versatile axis that makes it easy to manoeuvre and get into places that used to be fiddly or troublesome. I have extremely long hair that passes my bum and I swear I shed more than my long-haired, double-coated Pomeranian cross, but I have had zero issues with tangling in the vacuum head, which has been a blessing compared to my previous vacs, which have needed hair build-up to be chopped off the roll every few weeks. Quite literally, the only con I can think of is the tank size. However, that's no problem to me as my house is small and I have multiple bins about, so I don't mind emptying it as I go. The one-button empty mechanism is a blessing and I'm glad I no longer have to fiddle with the tank. All in all: amazing vacuum! Does everything it claims and exceeded my expectations. This is my first Shark and given many Dyson quality problems in the past, I don't think I'll be going back. Good job, you've converted me.
