The SharkFLEX DuoClean Corded Ultra-Light Upright Vacuum is convertible, lightweight, bagless upright/handheld vacuum cleaner, with novel wand design and DuoClean cleaner head. Models HV390, HV391, and HV392 are basically the same vacuum cleaner, differing only in available attachments. These units can be used as the main vacuum cleaner in smaller (and not just smaller) homes and apartments.
SharkFLEX DuoClean Corded Ultra-Light Upright Vacuum Features and Specifications
SharkFLEX DuoClean vacuums feature Shark’s DuoClean Technology (hence the name, of course), which is a combination of a bristle brush and a soft roller. Such combination clean various types of dirt and debris like fine dust, hair, small and large particles on both carpeted surfaces and bare floors.
SharkFlex Duo Clean Corded Vacuums: Tech Specs And Features
Part of the name. This feature enables the unit to fold the cleaning wand for flexible reach to clean under the furniture, appliances, beds, couches, tables and other similar, often rather hard-to-reach areas.
- Also, MultiFLEX Technology helps with compact, free-standing storage – when folded, HV390/HV391/HV392 vacuums require very little space.
Anti-Allergen Complete Seal Technology
In order to help people with pets and with health issues, SharkFLEX DuoClean comes with so-called Anti-Allergen Complete Seal Technology.
- Such technology helps the unit to capture and filter 99.9% of dust, dirt, pollen, and other potential allergens, 1 micron or larger in size.
- While the DuoClean main cleaning head helps with cleaning the floors, all three models come with cleaning accessories that help remove various dirt from furniture, upholstery, and other surfaces commonly found at home.
Obviously, the SharkFLEX models are not true HEPA vacuums (although this depends on the standards, too), but air filtration is very good.
- SharkFLEX vacuums come with several mechanical filters. Filters are washable and you can reuse them.
- Pre-motor foam and felt filters should be washed every month under normal usage.
- They should be removed from the unit, rinsed and then air-dried completely for at least 24 hours.
Post-motor filter should be washed every 8-9 months under normal usage. Again, it should be rinsed and then air-dried completely for at least 24 hours.
Note: Before putting the filters back into the unit, be sure that they are completely dry. Also, don’t use unit without the filters in place.
This feature together with the lightweight, ergonomic design provides a smooth ride over various floor surfaces. They also offer easy maneuverability, regardless if the unit is in upright mode or handheld mode.
- The SharkFLEX vacuum is powered with 600 watts (5 Amps) motor, providing strong suction.
- The motor comes with overheat protection; if the unit is clogged, airflow is decreased and the unit can simply turn the motor off. If this happens, turn the unit off, unplug it and check for potential clogs in the system. Let the unit cool off for at least 45-60 minutes before turning it on again.
- The power cord is 30 feet (~9.15 m) long and helps the user clean a large area without the need to change the power outlet.
Note: The cleaning wand extends the reach of the unit even further, helping to clean surfaces from the floor to the ceiling.
Obviously, due to the dimensions and design, there is no automatic power cord rewind mechanism.
Noise Reduction Technology
Shark’s so-called ‘Noise Reduction Technology’ reduces the noise during vacuuming.
- Although the unit is reported by many users as ‘not loud’, ‘quiet’ and similar, actual dB levels are not specified by the manufacturer.
Transparent Dust Cup
The transparent dust cup lets the user monitor the type and amount of picked up dirt.
- It is easy to empty – we recommend you to empty the dirt cup after each use.
- The dust cup capacity is 0.4 dry quarts (~0.44 l) to the ‘max fill line’.
Transparent Brushroll Garage
SharkFLEX DuoClean also features a transparent brush roll garage providing the user with quick and easy access from the top of the vacuum.
- Both stiff bristle brush and soft roller are of excellent design and help pick-up even pet and human hair, regardless of the length, however, they are not ‘tangle-free’ design.
- Their visual inspection is very important for maintaining the cleaners.
- When hair gets entangled, bristle brush and soft roller must be cleaned – which can be done rather quickly, just follow the instructions in the manual.
Note: SharkFLEX DuoClean are easy and simple to use vacuums, however, before the first use (and before assembling), read the manual/instructions.
The main cleaning head also features bright LED headlights – a great aid for cleaning in low-light conditions, like under the beds and furniture.
Note: If the LED headlights are flashing, brushroll garage is not closed properly.
Design and Convertibility
SharkFLEX vacuums easily convert to a handheld vacuum to clean areas like stairs, edges, furniture, and similar surfaces.
The unit’s slim design allows the user to reach various elevated surfaces like bookshelves, ceilings, windows, etc. and to clean tight and narrow spaces and areas.
- Unit dimensions are (H x W x D) 49 x 10.125 x 9.375 inches (~124.5 x 25.7 x 23.8 cm).
- The unit weighs 9.8 pounds (~4.45 kg) with the power cord, but without cleaning attachments.
In handheld mode, the unit is even lighter, but the total weight depends on the used cleaning attachment.

SharkFLEX DuoClean HV390/HV391/HV392 vs. Shark DuoClean Rocket HV380/HV381/HV382
All SharkFLEX DuoClean HV390/HV391/HV392 convertible vacuums follow the design philosophy of Shark DuoClean Rocket HV380/HV381/HV382 vacuums, but SharkFLEX vacuums come with several improvements.
Main Similarities and Differences between SharkFLEX DuoClean and Shark DuoClean Rocket Vacuums
- They are all powered using 600 W (5 Amp) motors via 30 feet (~9.15 m) power cords,
- They are all ultra-light convertible upright/handheld vacuums with DuoClean main cleaning head,
- The Shark DuoClean Rocket comes with a larger dust cup (0.91 vs 0.4 dry quarts) than SharkFLEX DuoClean vacuums. Since the dust cup can be easily emptied, it is not a big issue, it just can be a little bit annoying when cleaning very dirty floors and larger messes with SharkFLEX vacuums.
Available cleaning attachments depend on the model.
Also, if required, cleaning attachments for both SharkFLEX DuoClean and Shark DuoClean Rockets can be ordered separately.
The main difference (main improvement) between these vacuums is MultiFLEX Technology, which enables SharkFLEX vacuums to reach and clean areas that Shark DuoClean Rockets have issues to reach and clean. This feature is very important for homes with many potential obstacles and objects like tables, chairs, appliances, beds, sofas, stairs, corners, etc.
The models in the SharkFLEX DuoClean HV390/HV391/HV392 convertible vacuum series evolved from the Shark Rocket DuoClean HV380/HV381/HV382.
- They have good suction, very innovative flexible cleaning wand and other improvements, good air filtration, long power cord and come with very useful attachments.
- SharkFLEX DuoClean vacuums also cost slightly more than Shark Rocket DuoClean vacuums.
