It comes with just two accessories: a crevice tool and a two-in-one upholstery nozzle and dusting brush. Lots of premium cordless vacuums come with several more accessories, including a mini turbo brush - which is handy for giving awkward spots a thorough clean. I put the Shark IZ320UKT through my raw performance tests, measuring suction power in airwatts (AW), which uses a combination of airflow and suction. On Eco power, the vacuum runs at a basic 37.33AW, moving to 61.40AW on standard, which is about average for cordless cleaners. On Boost mode, the vacuum manages a huge 199.79AW; few cordless vacuum cleaners are this powerful, bar the Dyson V15 Detect, which manages an even higher 280.93AW. It's somewhat quieter in eco mode, but both the floor head and motor are still notably louder than some other cordless vacuums we've trialled.

There’s no on-body storage for these tools, although Shark does throw in an accessory bag for you to keep everything in. Shark quotes battery life at up to 60 minutes per battery running on Eco mode without a powered tool. I tested with a powered tool and found that it lasted 61m 28s on Eco power, 33m 58s on Standard and an impressive 17m 58s minutes on Boost. Recharge time is four hours for both batteries. As I said before, it delivers where it really counts, thanks to a powerful motor, large dust capacity and effortless movement around the house.On the whole Dyson vacuums are lighter and more compact than those offered by Shark. And when it comes to runtime of cordless vacuums, Dyson’s models also last longer than Shark. If we compare the Dyson V15 Detect with the Shark Anti Hair Wrap we’ve already mentioned, the Shark model offers 40 minutes run time while the Dyson has a battery life of 60 minutes. Both of these run times are based on using the vacuums on the standard mode but if you use the boost modes, you can expect the battery to drain faster.

I ran my carpet test to start with, placing a teaspoon of flour on the ground. Running the Shark IZ320UKT through the middle I got a clean collection of the dust on Standard power. Next, I ran the vacuum through the top on Eco mode and the bottom on Boost. There’s little to tell between the two, and it’s impressive that the Shark IZ320UKT can clean so well on its lowest setting.You get two batteries in the box, plus a charger that can take both batteries, so you can keep them both topped up all of the time. If you prefer, you can just charge the battery in the vacuum’s body by plugging in the power cable at the rear. However, you can get extra tools if you're willing to spend more. The pet variant (the Shark IZ300UKT) comes with a mini turbo brush, while the IZ320UKT comes with the same turbo brush plus an extra battery, letting you clean for twice as long without recharging. The Shark makes a lot of noise, so it's not a good choice if you tend to vacuum while others are asleep or working from home - even if they're on the other side of the house. Keeping the Shark emptied and clean is simple, too, with one button that releases the collection bin and filter unit from the device and a second button to open the trap door on the bottom to empty it. The filters can all be rinsed in running water and, since the vacuum also comes with Shark’s Anti Hair Wrap tech, you don’t need to worry about detangling regularly, either. This hasn’t transferred across to the pet tool, unfortunately, which gathered quite a bit of tangled hair during our testing. The Shark IZ201UK Cordless Vacuum Cleaner is one of the best vacuum cleaners for pet hairon the market. It has a 0.7 litre dustbin which, while not the largest, is adequate for cleaning most homes without the need to empty mid-way. We also enjoy how lightweight it is, at just over 4 kg.
