Low furniture and hard floors, with no app or account involved

A 2.85-inch-tall robot vacuum that slides under furniture a taller model cannot reach. It has no Wi-Fi, no app and no map: it navigates by bouncing off obstacles and is driven by an infrared remote. eufy rates it at 2000 Pa in Max mode, with about 100 minutes on hard floors in Standard.

  • Maker FAQ: Bounce navigation, no mapping; boundary strips not supported
  • Manual: 2000 Pa in Max mode, 0.6 L dust collector, 14.4 V 2600 mAh battery
  • Maker page: 2.85 in tall, passes under 2.87 in, climbs a 0.63 in threshold
  • Maker FAQ: about 100 min Standard on hard floors, 60 min BoostIQ, 40 min Max
  • Manual: filters cleaned weekly and replaced every 2 months; 12-month coverage
