Best for affordable, simple purification in bedrooms or medium rooms. Skip it if you need premium build quality, easy filter access every time, or very quiet high-speed operation.
Pros: air purification performance, noise level
Cons: build quality, maintenance ease
#2
Choose it only for a very cheap, very light vacuum for low-pile carpet touchups. Skip it for hard floors, allergies, large debris, deep cleaning, or homes needing strong filtration.
Pros: Weight, Carpet — Low-Pile Pickup
Cons: Carpet — Medium-Pile Pickup, Overall opinion
#3

Cons: filter availability, replacement experience
