What reviewers found
Dreame A3 AWD Pro 3500
- Notebookcheck: Tested the 3500: covered about 600 m² in roughly 4 h per charge, recharged from 15% to 100% in under 1.5 h, measured about 60 dB at 1 m, and showed a robot lifted error just over 70% on the slope ramp versus the 80% claim. Navigation was reliable but it sometimes touched obstacles lightly. Source
- M3 (4/5): Tested the 3500 on a steep, dog damaged lawn and got a fast, even cut with easy setup and no docking problems. Obstacle detection was reliable for people and pets but is specified for objects above 5.5 cm, so small toys can be missed. Gave it Editors' Choice. Source
Sunseeker X7 Gen 2
- Yanko Design: One week on a 6,777 sq ft Texas lawn with 32 oaks and an embankment. RTK fixed within a couple of minutes, the map held all week, it cut damp St. Augustine evenly, avoided a hose at night and fit through a 28 in gap. Source
- Homecrux: Hands on with five Sunseeker mowers sent by the company. The X7 ran at night, avoided obstacles reliably and left minimal missed spots; the article calls it the X7 Plus Gen 2 in one place and gives no measurements. Source
