Head-to-head
Levoit AERO vs Shark PowerDetect Clean & Empty System IP3251: AERO powers a sofa brush, Shark bends beneath it
The short answer
Choose AERO for its lighter listed stick, bagged disposal and included powered mini-brush. Choose IP3251 when reaching fur under low furniture and automatic mixed-floor response matter more. Shark’s MultiFLEX wand changes that access, while its reusable two-liter base avoids replacement bags.
Before you choose
The reasoning and the trade-offs
Above and below the sofa point to different winners
Shark’s hinge helps reach dry hair below the furniture. AERO’s included powered mini-brush helps with motor-driven agitation on the cushions. If your pet spends most of its time on the seat, prioritize the attachment. If the main nuisance is fur under a low couch, prioritize the wand.
What this is based on
Levoit AERO: Powered mini-brush included. Shark PowerDetect Clean & Empty System IP3251: MultiFLEX wand and passive Pet Multi-Tool.

Its reusable base still needs dust disposal, and the included pet tool is not a powered mini-brush.

How we reached this conclusion
Levoit AERO: Powered mini-brush included. Shark PowerDetect Clean & Empty System IP3251: MultiFLEX wand and passive Pet Multi-Tool.
A dock changes where you handle dust, not whether you ever do
AERO collects it in a replaceable bag. Shark transfers it to a reusable bin you eventually open. For a small apartment, consider where that final disposal will happen before comparing capacity. Neither system makes an unsupported guarantee about dust exposure in your room.
How we reached this conclusion
Levoit AERO: Bagged station. Shark PowerDetect Clean & Empty System IP3251: Bagless two-liter station.
Stairs make the stick weight the relevant measurement
AERO’s 4.4-pound figure is a vacuum figure. Shark’s 18.47 pounds includes its base. Comparing those directly would greatly overstate the load carried upstairs. Keep the dock downstairs and judge the cleaning unit and attachment you will actually carry.
How we reached this conclusion
Levoit AERO: 4.4-pound listed vacuum weight. Shark PowerDetect Clean & Empty System IP3251: 18.47-pound listing describes complete docked system.

Meaningful differences
What changes the fit
| What changes | Levoit AERO | Shark PowerDetect Clean & Empty System | Why it matters |
|---|---|---|---|
| Collected dust | 3.5-liter replaceable bag | 2-liter reusable bin | Choose recurring bag replacement or manual bin tipping. |
| Low reach | No equivalent folding wand documented | MultiFLEX | Shark has the documented hinge for reaching beneath furniture. |
| Furniture attachment | Mini motorized brush included | Pet Multi-Tool in the documented IP3251 kit | Only AERO’s listed tool establishes a small motor-driven brush in this pair. |
| Published weight context | 4.4-pound vacuum | 18.47-pound complete system includes dock | Never compare the stick against the whole Shark system to exaggerate a carrying difference. |
What you give up
Every choice has a cost
If you choose Levoit AERO
- The station requires replacement bags and permanent floor space.
If you choose Shark PowerDetect Clean & Empty System
- The bagless base eventually releases more dust during emptying than a sealed bag.
