DREAME Z30 Cordless Vacuum (310AW, 90-Min Runtime)
Most of the flagship cleaning experience, none of the flagship sensors, and a battery spec the expensive brands should be embarrassed by. The value pick of the category.
Best for: Apartments, condos, and rational buyers who want strong suction and long runtime without paying for lasers and LCD screens.

Legitimate large-room HEPA cleaning with a strong owner track record. The open questions are price against equal-coverage rivals and the long-term filter bill.
Best for: Allergy and asthma households, pet owners, wildfire-smoke regions, and anyone who wants one purifier serving a big living area instead of several small units.
