What reviewers found
Dreame Z1
- CyberShack (8.6/10): Ran 160 to 180 min in standard mode. A 20 m2 floor, 24 m2 wall and 24 m tile line test took 80 min and used 47% of the battery. Charged in 4 to 5 h and weighs 12.1 kg. Source
- The AU Review (3.5/5): Ran just under 3 h and charged in about 4 h. Strong suction, but missed tight corners, sometimes left debris on walls, moved slowly, and the remote and app connection were weak. Source
Ecovacs Ultramarine P1
- The Hook Up: Ran 2 h 9 min and covered 99% of the floor, 81% of walls and 38% of stairs and bench. Reached the coping at the waterline, captured silt well with the floss filter and leaked zero particles, but has a small bin and climbed the 8 in shelf enough to raise concern it could climb out. Named budget pick for sand, silt and pollen. Source
- EFTM (87%): Cleaned the test pool spotless in about 90 minutes and climbed walls and a two tier step. Charging from 5% to full took 3 h 40 min. Flipped upside down once after a wall climb. Source
