SharkFLEX DuoClean Features

SharkFLEX DuoClean HV390, HV391 and HV392 are latest models of Shark's ultra-light convertible vacuums and they follow the same design philosophy set long time ago. For previous Shark's ultralight convertible corded vacuums, check:

- Shark Rocket HV301, HV302, and HV305 Ultra-Light Upright Vacuums

- Shark Rocket DeluxePro HV321, HV323 and TruePet HV322 Ultra-Light Upright Vacuums

- Shark Rocket HV380, HV381 and HV382 DuoClean Ultralight Upright Vacuums

SharkFLEX DuoClean HV390, HV391 and HV392 come with all the good features of 'old' Shark models, but also include several improvements:

'DuoClean Technology' is a combination of two roller brushes in one main cleaning head. Both bristle brush and soft roller brush operate in unison to clean very fine, small and large particles of dust, pollen, pet hair and other dirt on both carpets and bare floors.

'MultiFLEX Technology' includes folding wand - it folds over for flexible reach and easier cleaning under beds, couches, tables and other objects and obstacles and provide compact, free-standing storage space-saving solution.

'Anti-Allergen Complete Seal Technology' is designed for cleaning up pets hair, pollen and other potential allergens and for keeping them in the vacuum itself. This technology allows capturing 99.9% of 1 micron or larger particles of dust and allergens inside the vacuum. 'True HEPA' vacuums filter 99.97% of 0.3 micron or larger particles and they exhaust practically clean air.

Note that there are several air filtration standards - nonetheless, air filtration provided by SharkFLEX DuoClean vacuums is very good, which is very important for people having asthma, allergies and other health issues.

'Active-Glide Technology' in combination with lightweight design provides a smooth ride over various floor types and good maneuverability around objects, obstacles, along the walls, edges, in the corners etc.

'Noise Reduction Technology' decreases the noise and change frequency spectrum that these units make. SharkFLEX are not noisy vacuums, but they are far from being 'ultra-quiet' units - unfortunately, actual noise levels in dB is not stated by the manufacturer.

sharkflex duoclean 2Other SharkFLEX DuoClean features include:

- a transparent removable dust cup for easy emptying of the picked up dirt. Also, units never lose suction as long as the dirt is below 'max fill line'.

- a brushroll garage for quick and easy access from the top of the vacuum and checking the condition of both roller brushes.

- power cord is 30 feet (~9.15 m) long providing long range using just a single wall power socket. Due to the design, units don't feature automatic power cord rewind system.

- cleaning wand can be removed, converting the units into the handheld vacuums for cleaning stairs, furniture, and other elevated surfaces.

- narrow design is suitable for reaching and cleaning narrow spaces and areas using the quick-release foot pedal to separate the floor nozzle and various available attachments.

- LED headlights are located on the main cleaning nozzle and they help the user clean in low lever conditions, like under the beds and similar.

- units come with 600 W (~5.5 Amps) suction motor providing very good suction in both upright and handheld modes.

- air filters are washable - under normal usage pre-motor foam and felt filters should be washed every month, while post-motor filter should be washed every 8-9 months. Note: never assemble the unit with wet filters and never operate the unit without the air filters.

Note: before assembly and the first use it is good practice to thoroughly read the manual/instructions.

Cleaning attachments although sharing the same or very similar name, they can vary between different generations of the Shark's vacuums. When looking for replacement or new cleaning attachments, be sure to verify that they fit your current model.

Obviously, as time goes by, Shark Rockets are becoming slightly heavier units, but they are also stronger and they come with improved cleaning tools.

Long Story Short: SharkFLEX DuoClean HV390, HV391 and HV392 are excellent convertible upright/handheld vacuums, suitable as the main vacuum cleaners at homes and apartments. Thanks to the novel wand design and available attachments, they can clean more easily areas and the dirt that were previously hard to reach and clean.

'Older' vacuums are still available on the market - they come with lower price tag, especially refurbished models. Nonetheless, they are still very good and practical units.
