Pros & cons

Dreame Z30

  • 310AW max suction — the highest of any stick near its price
  • Smart dirt detection automatically boosts power on dirty patches
  • Green dust-reveal lighting shows what you'd otherwise miss on hard floors
  • 0.6L bin is larger than the Dyson flagships'
  • Strong reviewer results on thick carpet and pet hair, with a deshedding tool included
  • 2-year warranty and a street price often under $300
  • Max mode drains the battery in roughly 10-15 minutes
  • 4-hour recharge is slow if you run it hard
  • No dock or auto-empty — manual bin dumping
  • Dreame's US service network is thinner than Dyson's
  • 90-minute runtime claim only holds in Eco with non-motorized tools

Dreame R20

  • 190AW is far more suction than anything else near this price
  • Soft-roller head pulls pet hair off hard floors without tangling
  • Blue illumination makes invisible dust obvious on hard floors
  • 90-minute Eco runtime with roughly 2.5-hour recharge
  • LED display with dirt-level feedback and mode switching
  • Very light in hand at 3.75 lbs
  • Weak deep-carpet performance — not the pick for carpeted homes
  • Hair wraps on the V-brush carpet head
  • High-pitched motor whine bothers some owners
  • Max-mode runtime is a fraction of the 90-minute rating
  • No app or spare-battery ecosystem
