    The vacuum cleaner offers strong suction power that effectively cleans carpets and floors, including picking up significant amounts of dirt and pet hair. The auto-detect technology adjusts suction based on the surface. While some users experienced issues with the filter, power cord, and stability, the majority of customers are highly satisfied with the product's performance.

    Makes a chore out of a chore
    I find it quite difficult to use. It self propels into furniture and is I really heavy to pull back. The on/off button has a delay. The power cord is stiff and unwieldy. It has an upholstery tool that doesn’t fit properly on the unit and makes it impossible to “lift away” when in situ. An enjoyable chore has become more time consuming and difficult to do.

    Great vacuum
    [This review was collected as part of a promotion.] My first Shark vacuum wasn’t disappointed picked up so much more than I’d expected

    Bit stiff
    We've had ours since June '25 so just shy of a year and the cable has split already where it loops around the cable tidy loop thing on the handle. The cable is extremely stiff and has very little give in it. I suspect the cable will eventually split in multiple places where it loops round. Also the extendable hose is not very extendable - when you detach the handle, you only have a small amount of length you can move the handle before it pulls the vacuum over. Apart from that tho, the PowerDetect feature, and the floor surface sensor is brilliant. Works so much better than our previous Dysons
