    What customers say
    Generated by BazaarVoice HarmonyAI using customers reviews

    Customers overwhelmingly praise the vacuum for its powerful suction and transformative cleaning results, with many noting it pulls out far more dust and hair than previous models, leaving carpets looking brand new. Reviewers highlight intelligent features like Power Detect, auto-floor detection, lift-away functionality, and anti-hair wrap technology as game-changers that reduce maintenance and enhance ease of use. The sturdy construction and 5-year warranty drive strong brand loyalty, with many customers purchasing repeat units. Some mention weight challenges on thick carpets, and a few report occasional issues with cords or brush performance, though these concerns are far outweighed by positive feedback.

    THE BEST Upright vacuum cleaner
    This has to be THE BEST Shark vacuum cleaner I've owned, and I've owned a few. I'm a guy who loves a good vacuum cleaner as much as I like a clean carpet, and this Shark AZ3900UKT is just brilliant at doing the job. The suction is insanely good, much more than my previous Sharks, and feels like far more than the competition. It's got a ridiculously clever floor head that senses the floor type, and ensures the perfect level of brushing, vibrating and vacuuming to leave it spotless. As well as the brushing, it vibrates the particles free, I guess in the same way car detailers use massage guns to bring the dirt to the surface. You can even see the dirt in the carpet being vibrated out of it ahead of where you're about to clean. The build quality is really good. Strong an sturdy in the right places, and also lightweight so you don't feel like you're lugging it around. In automatic mode, it really goes for it, and the forward pull of the head on the floor can feel like a bit of a workout trying to stop it inhaling the universe, but all this means you get a thoroughly decent clean, in far less time. If you're considering this model, I'd recommend it.

    Best vacuum cleaner for pet hairs.
    I have a Golden Retriever so dog hairs are a problem. This is by far the best vacuum cleaner I have had to tackle this problem. I love the features, such as the “detect” mode and the fact that it’s easy to empty. Because it is powerful it is easy to use and it’s almost a case of guiding it rather than pushing it. However, that is also the only reason I held back on the fifth star, because although pushing it forward is easy it can sometimes be a bit heavy to pull back. Having said that I would highly recommend this cleaner to anyone with pets.

    Awful and feels cheap
    This vaccum is awful, the detect function doesn't work on carpet, it just refuses to work, we have to select thick carpet for it to work, our carpet isn't thick. Took it back as thought it was faulty and the new one is just as bad. The vacuum itself is very clunky, it feels like its cheap. The wire is awful, very stiff and not as flexible as the old one I had, making it hard to wrap up once finished with, again feels cheap. The suction is good but a head ache to use after having to switch off and on just to get it to hoover our carpet.
