shark ionflex duoclean 2Shark IONFlex DuoClean and 2x DuoClean vacuums come with main cleaning nozzles featuring so-called DuoClean Technology. A DuoClean Technology basically combines bristle brush and soft roller into one cleaning head and enables cleaning of the fine dust and small and large particles on both carpets and floors with a fewer nozzles passes, improving the cleaning and reducing required time to do the same task.

Note that both bristle brush and soft roller are of 'classic' design - they are not of tangle-free or similar design, thus must be periodically cleaned, which can be done rather quickly thanks to the design of the main cleaning head.

Models IF200, IF201, IF202, and IF205 come with a single battery, while models IF251 and IF252 come with two lithium ion batteries and a charging cradle.

One of the very interesting features of Shark IONFlex DuoClean vacuums is so-called MultiFLEX Technology. This technology enables the vacuum to fold over for very compact, free-standing storage, requiring very little space and a small footprint. More importantly, it also provides flexible reach to clean surfaces that would otherwise be very hard to clean like under beds, furniture, couches, tables, etc.

Thanks to so-called Smart Response Technology, Shark IONFlex vacuums come with a range of power settings for both main cleaning nozzle and for the suction strength. These power settings enable cleaning of various surface like carpets, rugs, various bare floors, upholstery etc. balancing between performances, length of operating time and protection of cleaned surfaces.

In simple words, these vacuums come with a surface settings and suction settings.

Surface settings: carpet setting (for cleaning high pile carpets - both brush rolls spin faster to pick up deeply embedded dirt from the carpets) and floor setting (for cleaning bare floors and area rugs - both brush rolls spin slowly for gentle cleaning of the hard floors and delicate rugs. The Soft Roller traps fine dust and large particles, while the brushroll picks larger debris and directs everything into the suction channel).

Suction settings: extended runtime (low setting - for everyday cleaning) and max power (high setting - for heavy duty cleaning and cleaning of stubborn messes).

Maximum operating time thus depends on the surface settings (if main cleaning nozzle is used) and suction settings. Operating time varies from approximately 15 minutes (maximum suction, carpet setting) to 40 minutes (extended runtime, non-powered cleaning attachment, like crevice tool or similar).

Although 15 minutes doesn't sound much, these vacuums can clean rather large area during this time. Also, it takes around 3.5-4h to fully charge fully drained battery. Battery is rated at 25.2 V and provides 11.9 Amps for maximum power of 300W, which is comparable with the best and strongest cordless vacuums on the market. However, we where unable to find actual AW (Air-Watts) rating - that would enable real-life suction comparison between Shark IONFlex vacuums with other similar cordless (and corded!) vacuums - nonetheless, suction is very good, comparable even with lighter corded vacuums.

To get accustomed with your new unit, it is highly recommended to thoroughly read the manual/instructions that come with the vacuum.

Duster Crevice Tool are two cleaning tools in one. The crevice tool extends the reach and enables the cleaning of small and narrow spaces, while the dusting brush cleans a multitude of surfaces by agitating the dust and other small particles, which are then picked by strong air flow into the vacuum cleaner.

8” Crevice Tool is design to clean tight spaces and areas. Also, it helps clean edges, baseboards, corners, ceilings, between car seats, bed cushions etc.

Anti-Allergen Dust Brush is cleaning tool specially designed for removing fine dust, allergen particles, pollen and similar small debris from various areas, including the most delicate surfaces. This tool is very important for people having asthma ans similar health issues.

Motorized Pet Tool is deep-cleaning motorized compact brush, designed to remove deeply embedded dirt, hair and allergens, from multiple surfaces, including smaller carpets, sofas, stairs, and similar areas where main DuoClean cleaning head is too large to be used comfortably.

Pet Multi-Tool is actually two tools in one, designed for cleaning tough pet and other messes. First tool is a stiff bristle brush intended for cleaning stuck-on debris. After cleaning with stiff bristle brush, remove the bristles and clean the mess with upholstery tool which is designed for removing stubborn pet and human hair, lint and similar debris from furniture, upholstery and similar surfaces.

MultiFLEX Under Appliance Wand is a type of pivoting wand which can be extended to clean under and on top of the appliances, furniture and similar object.

Of course, Shark offers many more cleaning attachments and kits, suitable for various types of dirt, surfaces and situations and they all can be ordered later, if required.

Shark IONFlex DuoClean Weight: without accessories, these units weigh 8.7 pounds (~3.95 kg) in upright vacuum cleaner mode and around 3.5-4.5 pounds in handheld mode, depending on the attachment used.

Unit is designed and light enough to be easily used and to be able to maneuver around the furniture and other obstacles.

Air filtration is good, but these vacuums are not true HEPA vacuum cleaners. Filters are washable and if required, they can be ordered and replaced.

Note: never assemble and use the vacuum without the filters or with wet filters. For more about maintaining and using your unit, check manual/instructions.

Dirt cup is transparent, enabling the user to see the amount of vacuumed dirt. Dirt cup is emptied easily and quickly - since the volume of the dirt cup is 0.33 liters, when vacuuming heavily soiled floors, expect to empty the dirt cup often.

Note: when amount of dirt reaches 'Max. Line', stop with the vacuuming and empty the dirt cup.
