What should I look for in a budget cordless vacuum under $150?

Look for a self-standing design, an anti-tangle brush, and a removable battery, plus real reviews rather than just a high Amazon star average. The Tikom V500 and Levoit LVAC-200 draw the strongest budget consensus, while reviewers warn that many near-identical 55KPa Amazon listings have soft, ineffective brush rolls and weak quality control.
