The catch
Levoit AERO
What you take on is recurring bags, with no documented MultiFLEX-style hinge.
Side by side
Levoit AERO vs Shark PowerDetect Clean & Empty System IP3251: Shark bends beneath the sofa, AERO powers a sofa brush
Quick verdict
AERO is the pick for a lighter listed stick, bagged disposal and an included powered mini-brush. IP3251 is the pick when reaching fur under low furniture and automatic mixed-floor response count for more. Shark’s MultiFLEX wand changes how you get to that spot, and its reusable two-liter base means no replacement bags.
Before you buy
Why, and what it costs you
Over the sofa and under it, the winners differ
The hinge on Shark makes it easier to reach dry hair below the furniture, while AERO’s included powered mini-brush brings motor-driven agitation to the cushions. When your pet spends most of its time on the seat, put the attachment first. When the main nuisance is fur under a low couch, put the wand first.
Where this comes from
Levoit AERO: Powered mini-brush included. Shark PowerDetect Clean & Empty System IP3251: MultiFLEX wand and passive Pet Multi-Tool.

A dock shifts where you handle dust but never spares you from it
Dust ends up in a replaceable bag with AERO. Shark moves it to a reusable bin that you eventually open. In a small apartment, think about where that final disposal will take place before you compare capacity. Neither system makes an unsupported guarantee about dust exposure in your room.
How we worked this out
Levoit AERO: Bagged station. Shark PowerDetect Clean & Empty System IP3251: Bagless two-liter station.
On stairs, the weight of the stick is the figure that counts
AERO’s 4.4-pound figure is for the vacuum itself. Shark’s 18.47 pounds includes its base. Setting one directly against the other would greatly overstate the load carried upstairs. Leave the dock downstairs and judge the cleaning unit and attachment you will carry.
How we worked this out
Levoit AERO: 4.4-pound listed vacuum weight. Shark PowerDetect Clean & Empty System IP3251: 18.47-pound listing describes complete docked system.

Spec by spec
Where they really differ
| Spec | Levoit AERO | Shark PowerDetect Clean & Empty System | In practice |
|---|---|---|---|
| Collected dust | 3.5-liter replaceable bag | 2-liter reusable bin | Decide between recurring bag replacement and tipping the bin by hand. |
| Low reach | No equivalent folding wand documented | MultiFLEX | For reaching beneath furniture, the hinge is documented on the Shark. |
| Furniture attachment | Mini motorized brush included | Pet Multi-Tool in the documented IP3251 kit | In this pair, a small motor-driven brush is established only by the tool AERO lists. |
| Published weight context | 4.4-pound vacuum | 18.47-pound complete system includes dock | Do not set the stick against the whole Shark system to inflate a difference in carrying. |
