We assess the cleaning performance of each vacuum cleaner, compare it to the competition, and then rate it. This score shows how well each cordless vacuum cleaner picks up dust from in between the crevices that you find between traditional floorboards. This comes sealed in a can about the same size as a gourmet cat food tin, and slots into the floor head, releasing a pleasant odour as you clean, much in the same way as the similar system in the Henry Quick. Other nice touches with this vacuum include the headlights on the DuoClean brush roll head, which are fantastic for getting under cabinets, beds and other furniture to capture dust.

Shark has placed the controls well: there’s a power button and mode control right where my thumb goes. The detail of some added flexibility in a stick vacuum is an exciting notion for a cleaner as reluctant as myself, as well as the pledge that this has Shark’s “best ever hair pick-up”.We used the Stratos with both the narrow crevice tool and the multi-surface tool to thoroughly remove hair, dust and dander from sofa upholstery. With the CleanSense mode selected on the vacuum cleaner, it can adjust its power according to the mess, which is good for battery life, as the vacuum cleaner only uses as much power as it needs. Based on how well this vacuum cleans, that amount of time is more than enough to clean an average-sized house, and you wouldn’t need a plug-in cleaner. And, with Flexology, you can bend the wand to reach under low furniture such as beds, sofas, and coffee tables.

This test is particularly important for serious allergy sufferers who want to remove all of the fine dust and allergens they can from their home. We cannot fully attest to whether the anti-allergen Complete Seal is really comparable to it in our tests. If you want to find out more about Dyson cordless vacuums, you can read our comparative review here. If too much hair and fluff has tangled itself around the brush rollers, it can decrease your vacuum’s suction power . If necessary, you can then easily remove the rollers on the Shark Stratos to thoroughly rid them of any dirt.

When the vacuum senses more debris, it'll amp up the suction power used, and the bar will illuminate to reflect that. Anti Hair Wrap Plus removes long, short and pet hair from the brush-roll as you clean so you don't have to. Thanks to two Lithium-Ion batteries, you’ll get up to 120 minutes of power – plenty of time to clean a typical home from top to bottom.

Type This is a cordless stick vacuum cleaner that can stand up by itself thanks to Shark’s Flexology tech. On my first use, to my shame, the suction was so effective that even after just five minutes, the Stratos' dust bin was filling up. It's also more affordable and might be more reliable in the long run (by comparison, our reviewer's Dyson Outsize broke down 10 months into using). After cleaning with the Shark Stratos anti-allergen dusting brush, our cupboards are now also free from dust.Please note this also supports the refurbished models IZ400UKREF, IZ400UKREFB, IZ400UKTREF, IZ400UKTREFB, IZ420UKTREF and IZ420UKTREFB. Our reviewer Millie Fender said in her Shark ICZ300UKT Anti Hair Wrap Cordless Upright Vacuum Cleaner review‘one of the best things about the Shark ICZ300UKT is how powerful it is on carpets. This is mainly due to the two rollers on the left and right of the floor head and the movable joint.
