Shark Anti Hair Wrap Cordless Stick Vacuum Cleaner with Flexology [Twin Battery] IZ251UK is rated 4.9 out of 5 by 20.
Rated 4 out of 5 by from Great Vacuum but heavy I must admit that I was sceptical at first that this could clean better than a corded vacuum but the amount of dust picked up the first time I used it was amazing. Anti hair wrap works very well, three long haired girls in the house used to put all previous hoovers under pressure and I was always cleaning out the brushes. The only downside to this vacuum is the weight of the motor and battery. All the weight is at the top and it takes getting used to and it made my forearm ache the first couple of times I used it. Twin batteries are useful as they don’t last as long as advertised. The motor brush reduces run time. All in all, I’m very happy

Rated 5 out of 5 by from Love it I have had every make of vacuum some good some awful but not one that I could title as great, until now. I love the cleaner, pleasure to use goes from hard floors to carpet in an instance grabbing all dirt, bits & anything else with no effort at all. Love dual battery pack, gives you loads of cleaning time, folds up to nothing if takes hardly any room in the cupboard. If I have a gun to my head and had to find something I would say it is a LITTLE heavier than some vacuums but nothing that makes me need muscles like Arnie, but vacuuming now takes minutes whereby before with others I needed to go over floors quite a few times or bend and pick up what the vacuum turned its nose up too. Price I paid was fab, so from this you know I have not been given this machine to try out I put it with my own cash and every penny was well spent.

Rated 5 out of 5 by from Amazing!! Loving the cordless vac Thought I would give it a few weeks before I wrote my review..just to see if I was in a false sense of excitement about my new shark!! Well I arent!! It is as good as it was from the first day! So much easier than having to carry a very heavy vac up the stairs plug it in etc!! It’s fab!! I love every feature and Even my 12 year old son now vacs his room!! Result!! The various attachments make it so adaptable and car friendly too!! The fact you also get two battery’s is great as you never have to be out of charge!!

Rated 5 out of 5 by from Fantastic cordless vacuum from Shark Having used another brand of corded vacuum for over 20yrs I am wondering why I waited so long to switch to a cordless Shark! It has not only great suction ( a choice of three options - hard floor, carpet and a boost to choose from), but it is very light and manoeuvrable. The battery has a great life, and being supplied with two means that you always have one to hand that is charged. It has a number of tools that come with the Shark that are really useful to get into the small nooks and crannies in your house - and car. It folds in half when not in use so its easy to store - and the headlights are a useful addition as it goes really easily under furniture so you can see what you are vacuuming up which has previously been more challenging. All this and its quiet - so now there is no excuse not to have clean floors even when my daughters alseep! I love it and wouldn't hesitate to recommend this cleaner to others. Go on do yourself a favour and get a Shark Cordless stick vacuum cleaner.

Rated 5 out of 5 by from Excellent run-time! This vacuum is great. We previously had an older Shark cordless stick vacuum and the run-time on this model is nearly double our previous cordless vacuum! I also love having one battery in the vacuum and a second on charge ready to swap over whenever I need it. Anti Hair Wrap is a great feature too. I'm no longer finding myself cutting the hair out of the brushes with a pair of scissors!

Rated 5 out of 5 by from Modern and sleek vacuum! My first impressions of the Hoover is sleek, modern and aesthetically pleasing. It is all round, a wonderful piece a kit. I wasn't sure about it as I only recently heard of the brand a few years ago, but I was pleasantly surprised. The power is remarkable on all surfaces. It offers two settings, both allow excellent retention for your desired floor, whether that be carpet, wooden or laminate flooring. The mechanics of the design allow for smooth rolling and flexibility to get into every corner of an ever changing living quarter. It turns into a hand held device and comes every some great accessories to adapt to different surfaces. It's great for in between the sofa and even the bed sheets. It comes with two batteries, so when one finishes, you can easily swap it out. The battery life is itself, it quite impressive. You may find yourself empting out the contents often; however this is expected considering it is a cordless machine. The weight is slightly heavy, this makes it tiresome after sometime, although it helps with Hoovering. The hair catching feature is one the best things about the hoover as I never really got that from any other previous one I've owned. So, all in all, I'm really happy with the product and I have my guests jealous, so much that they even offer to do some chores (hoovering) when they are round!

Rated 5 out of 5 by from Best Buy I brought this hoover to treat myself after Christmas. I’m so glad I brought it, best suction, battery life seems good enough and I love all the different parts for hoovering different places around the house. Also having 5 years warrenty is great!

Rated 5 out of 5 by from Hoover of the future We have had this hoover for a couple of weeks and we could not be more impressed. It is compact, light weight, easy to put together and simply the most powerful hoover on the market. It picks up all the small particles of dust and dirt that our previous hoover failed to find leaving the carpets and rugs looking brand new again. The upholstery attachment is a great addition keeping the sofas looking pristine while also being gentle on the velvet fabric. We waited for the launch of this particular model as it features the anti hair wrap. The days having to cut hair from the hoover rollers are now long gone. I could not recommend this hoover highly enough.
