Flooring first
A vacuum that works well on carpet may behave differently on hard floors.
Upholstery matters
Furniture and stairs can make small powered or fabric tools more important than raw floor-head specifications.
Maintenance burden
Hair wrapped around brush rolls can increase routine maintenance, so tool-free or accessible designs can be useful.
Avoid medical promises
A vacuum may reduce visible hair and particles but should not be treated as a medical treatment for allergies.
