Making Your Decision
When to Choose Levoit AERO
Weight-sensitive users who want ultralight cleaning with auto-empty convenience
The Levoit AERO is the lightest cordless vacuum in our lineup and pairs that with a 60-day auto-empty dock. Suction is modest, but the 4.3 lb weight makes it effortless to use on stairs and above-floor surfaces.
Strengths
- Lightest vacuum in our roundup at just 4.3 lbs
- Auto-empty dock with 60-day capacity
- 70-minute runtime in standard mode
- 5-layer filtration captures 99.99% of particles
Limitations
- Lower 180 AW suction than performance-focused rivals
- Small 0.45L on-board dustbin fills quickly without dock
- Newer brand with limited long-term reliability data
When to Choose Shark PowerDetect Clean & Empty IP3251
Busy households that want hands-off maintenance with powerful auto-empty convenience
The Shark PowerDetect IP3251 pairs strong suction with a 45-day auto-empty dock for true set-and-forget convenience. The weight trade-off is real, but the hands-free maintenance is hard to beat at this price.
Strengths
- Auto-empty dock holds up to 45 days of debris
- PowerDetect technology auto-adjusts suction by floor type
- ~314 AW suction rivals premium competition
- DuoClean head tackles both hard floors and carpets
Limitations
- Heaviest vacuum in our roundup at ~8 lbs
- Bulky dock requires dedicated floor space
- Dock noise can be loud during auto-empty cycles
