Shark PowerDetect Corded Upright Vacuum Cleaner with DuoClean Detect, Reverse Clean, Hair Wrap Plus, Anti-Allergen, Anti-Odour, Pet, Crevice & Multi-Surface Tools, Portable, 750W, 1.3L AZ3900UKT

Can't comment on longevity as I have only had it a week but by far the best hoover I've ever owned! I've used Henry's for years but never found them great for pet hair and a really dirty carpet, this by far surpassed my expectations and leaves the carpet looking new. Lifts the pile and thoroughly cleans it. On the first use I couldn't believe there was that much dirt left only having hoovered the day before with my old Henry. The power and suction is far superior and it's very easy to use. Even though expensive, I think it's great value for money and you certainly get what you pay for. Highly recommend.

Oh my word! This vacuum has a mind of its own! Will hunt down any dust or dog hair and will suck it up! I have had a shark for a few years and this one is like a Lamborghini of cleaners! Very powerful, vacuum lines on carpet that has been down years and the pile is now like new. Honestly the best thing. It is heavy and pulls away looking for the dirt but I think of the arm workout I am gaining from it!

I spent a lot of time reviewing various vacuum cleaners before I decided on the Shark AZ3900UKT. I was after the AZ4002 but this is not available in the UK thanks to Europeean directives.Purchased AZ3900UKT from Amazon and delivered just two days later.Firstly, I was very impressed with the packaging Outer box is very sturdy, opened to find an inner box which was also very sturdy. I was very pleased when opening the inner box to find absolutely no plastic. Everything was neatly wrapped and protected with either paper or cardboard – all of which can be recycled.Assembly was straight forward and everything fitted together with a pleasing solid ‘click’. The only thing that foxed me initially was the cover for the odour eliminator which seemed to be missing – I didn’t realise it was inside the tin already fitted to the actual odour eliminator cartridge…Doh!The accessories included the following:• Shark 8" Crevice Tool• Shark Pet Multi-Tool (two part)• Shark Anti Hair Wrap Pet Power Brush – this was a pleasant surprise as it is not stated on the Shark Website but is on Amazon where I finally purchased it.All reviews (and on Amazon product description) prior to purchase stated that the power wattage is 750W (wattage is not shown on the Shark website) so I thought I was purchasing it at 750W. However the box states 600W and so does the Owners Guide and on the unit itself, so this was a little concerning that it might be under-powered. Shark – Has the wattage been reduced? Comment please Shark!First use: I thoroughly vacuumed the bedroom carpet (which was already clean) with my aging Dyson so was not surprised with little debris in the tub. Then I went over gain with the Shark (Default Detect mode) – I was astonished at the extra debris it collected on what I thought was an already clean carpet!. On this mode, the vac does want to pull away forward but not a problem and actually makes the operation easier – contrary to some of the reviews that I have read.The reverse cleaning works really well and was one of the reasons I selected this machine in order to double the efficiency and shorten the cleaning time.I then moved on to hard floors – laminate and tiles still with Detect mode selected. It automatically slowed the rollers and altered the suction. This was also really effective. Running back then to Carpet, the Detect mode auto switches back to carpet mode. In all honesty, I can not see me often moving away from ‘Detect’ mode very often apart from cleaning my lightweight rugs.The 1.3L dust/Debris bin is not as large as on either of my two Dyson machines but this is not a problem – just empty it a bit more often – and it compacts the debris better than my Dysons anyway.Lights: I considered lights on a vac as rather gimmicky, but how wrong I was! The front headlights work extremely well on both dual and single edge detect. Also, the LED on the handle is fabulous when using it in lift-away mode. I have changed my tune!The Anti-Odour cartridge doesn’t really do anything (for me anyway) – I can’t detect any residual perfume (even when its on max) after vacuuming, perhaps my sense of smell is degraded.The ONLY Bad point is the quality of the cable – it is too stiff and I think the flexible union where it joins to the main shaft will degrade in quite a short time – I hope I am wrong - I think that Shark should improve this aspect and make the lead more rubberized and flexible.All in all, the Shark AZ3900UKT is a quality (but pricey) vacuum cleaner that performs very very well.So far, very pleased.

Having been a loyal Vax customer for 15 years, we thought we would have a change. We had a pet Vax vaccum, about one year old, cats, low carpets, used the Vax earlier today and assumed job done. We used this Shark in the same room upon arrival. Look what the Vax missed! It is easy to assemble , but I would say, having every part wrapped in paper is excessive. The ring pull on the odor capsule also snapped on opening. However, the somewhat power assisted drive moving this around the room and the output is very impressive on face value.

Firstly, this arrived within two days of ordering and it was packaged really well and all recyclable. No plastic, and all the packaging is either cardboard or brown paper and one element is inside a metal can.This vacuum was bought as a replacement for my decades old trusty Dyson which had seen better days and I was beginning to find difficult to lug upstairs. I was surprised to find this model was also quite large and I considered returning it. However, because it has the clever lift-away function I decided the size and weight was not really a deal breaker. I tried it first on my living room rug (which I had already vacuumed) and the amount of dirt that this machine lifted was, to my shame, astonishing. So it’s definitely staying. The suction is excellent. Too strong really for the couple of very deep piled rugs I have.It has a useful high tech detect function that changes colour from white to purple to indicate how much debris is present and I like the lights on the front that lets you see the dust on hard flooring.The lift-away function makes vacuuming the stairs a breeze and I just leave the lift away section at the top of the stairs while I collect the motorised floor head attachment from downstairs so I’m not having to carry the whole thing up and down the staircase.The dust emptying is very similar to the old Dyson and no replacement bags are needed.The power cord is very long but it is unusually stiff.I’m very happy with the purchase.

It picks up everything and makes the carpets look much better. We like that it has an auto setting so it will adjust to whatever flooring you’re cleaning.My only concern is it’s quite heavy, good when going forward but hard to pull back.Otherwise we are more than happy with it.

My new Shark only arrived this morning but I've already been round the house with it! Its an absolute beast of a machine and you can feel the suction on the carpet! The amount of dust it removed is embarrassing especially as I only hoovered yesterday with my much older Shark! Would definitely recommend. Really easy to put together and quick to get started. The only negative is it's heavy! So if you want a lightweight hoover this one might not be right for you!

One of the best vacuum so far in the market, strong suction pulls all the dust from carpets and has all the new technology.
