Overhead cleaning using just the wand makes the task less cumbersome than with other cordless vacuums.

The removable battery has a handle and is positioned for easy access so it can be removed quickly when it needs recharging.While removing the battery is quick and simple, if you prefer to put the vacuum on a charging dock or plug a cable directly in, this isn’t the vacuum for you. The IZ300UK is much cheaper than the latest cordless Dyson, the Dyson V15 Detect Absolute, but there's no doubt that Shark is pitching its tanks on Dyson's lawn. The carpet brush has the usual bristles, but also has Shark’s PowerFins – strips of stiff fabric that do a great job of flicking particles out of the carpet and into the vacuum inlet.

The two rollers of the DuoClean floor head are hard-working and do a terrific job in a variety of tricky situations.Just like Shark’s cordless sticks, the ICZ300UKT has a removable battery that lifts out of the unit and charges in a separate dock – this takes around 3. You can clearly hear the Shark ICZ300UKT and can’t really hold conversations over it, but it isn’t so loud as to be annoying. The Shark ICZ300UKT made quick work of cleaning the tiles in my kitchen, and while the brush head is quite large, it puts the roller brush out in front so it is able to reach into the underside of cupboards or along skirting boards. I started off by measuring the Shark ICZ300UKT’s raw performance in AirWatts (AW), which is a combination of suction power and airflow.
