Flexology bends to reach and clean under low-lying furniture and folds for compact, freestanding storage at the touch of a button. It’s an improvement over the basic LED lights on the battery (the three show the rough power left) although not quite as advanced as the Dyson V15 Detect, which shows battery power remaining in minutes. First, there’s a new DuoClean floor head, which is designed for even better pet hair pick-up, while preventing hair from getting wrapped around either the hard floor roller or carpet brush. This applies to the following SKUs IZ300, IZ300UK, IZ300UKT, IZ300UKTQ, IZ320, IZ320UK and IZ320UKT. The model reviewed here comes with Shark’s TruePet attachment (the T in the name) – a mini motorised head for use in the vacuum’s handheld mode.

The brushes won’t need much cleaning because the anti-hair wrap guards should stop any hairs from getting tangled up in the rollers, but you might still want to give it a once-over every now and then. This floorhead is the new version with PowerFins, which are designed to agitate dirt in carpet better, making the vacuum cleaner more efficient and effective. Most of our test carpet appeared visually clear of flour, except for a small amount that wasn’t collected near a carpet wrinkle. Fully extended, its dimensions are 260 x 245 x 1,180mm (WDH), and there’s a hinge in the middle of the extension wand that lets it fold down to 690mm in height for storage or be used for cleaning under low furniture.You get three different speed settings, changeable via the handy control panel by the handle, as well as the option to swap between carpeted and hard floor settings. There’s little to tell between the two, and it’s impressive that the Shark IZ320UKT can clean so well on its lowest setting. Enjoy up to 120 minutes run-time† with this twin battery model, charging the removable batteries wherever suits you. With up to 60 minutes of runtime each, we reckon you’d only need to charge them about once a month, depending on how often you use your device.

There are three power modes to choose from (Eco, Standard and Boost), plus you can choose between carpet and hard floor modes, which adjust the speed of the floor head.

Again, not a huge issue, but it’s annoying when it gets jammed under there as I’m cleaning the floor nearby.Shark’s impressed before with its Flexology cordless cleaners, which give you easy storage and simple under-furniture cleaning.
