About the Shark IZ420UKT
The IZ420UKT is Shark's Stratos stick with the Pet Pro kit. It weighs 2.16kg and has a 0.57L dust cup. The floorhead is DuoClean: one head with two brush-rolls, for carpet and hard floor. Anti Hair Wrap Plus strips hair from the brush-roll as you clean, and LED headlights light the floor ahead. Clean Sense IQ adjusts suction to the dirt it detects, and an indicator on the floorhead shows the change.
Two removable lithium-ion batteries are in the box. Shark's 120-minute figure is for both batteries used one after the other in eco mode with the non-motorised tool. By mode, Shark's support figures are up to 60 minutes as a hand vacuum in eco, 46 on bare floor in eco, 30 on carpet in eco, and 10 in boost on the hand vac. The dual charger dock charges both batteries at once, and a battery can also charge on the vacuum. Charging takes 3.5 hours.
The kit includes a 30cm crevice tool, a multi-surface tool, an anti-allergen brush, a motorised pet tool for embedded hair on upholstery, an accessory bag and an odour puck. Anti-Odour Technology uses a cartridge, and a replacement is sold separately. Shark describes the anti-allergen complete seal as keeping 99.9% of dust and allergens inside the vacuum.
What owners report about the Shark IZ420UKT
There is limited owner feedback for this exact model that we could read. The reviews on Shark's own page are mostly positive: owners call it a clear step up from earlier vacuums, light to push, and longer-lasting on a charge than an older Shark.
The complaints centre on the battery. Several owners say real runtime is shorter than the headline figure, with one reporting 15 to 20 minutes per battery on a medium setting, which fits Shark's own 30-minute carpet figure for eco. A few also report battery charge dropping quickly towards empty.
Other issues are less common. One owner found the floorhead locking mechanism stopped engaging properly after a few weeks, and another saw debris fall out when the vacuum was switched off. Opinion on comfort is split: one owner found the handle uncomfortable and the machine heavy, while others call it light.
Who the Shark IZ420UKT suits
It suits a mid-sized home with pets, where the pet tool and anti-tangle brush earn their place and a second battery means fewer stops. At 2.16kg it is easy to carry up stairs. Buy it expecting around an hour on bare floors and about half that on carpet per battery, not the full two hours.
Look elsewhere if your home is large and mostly carpeted, or if you hate emptying the bin: the 0.57L cup fills quickly, and the Shark PowerDetect Speed Clean and Empty Pet Pro IA3241UKT empties itself. For the longest runtime from one pack, the Bosch Unlimited 10 BCS1051GB is the better fit.

Other cordless vacuum cleaner picks
The other badge winners in our cordless vacuum cleaners ranking.
Every score here comes from our ranking model; no editor sets the order. Most of each score is what the review sites say: the scores their own reviews give each model, and whether their best-of lists name it. For this guide we read Homes & Gardens, Real Homes, T3, Trusted Reviews and Wired. The rest is how happy owners are, held back where few owners have rated a product, and how new it is. Value for money earns its own badge rather than a higher place. We compared 21 models for this guide before settling on these ten.
Brands can't pay to be included or to move up. We last checked these picks in November 2026.
