Verdict

The ECOVACS DEEBOT OZMO 920 is a 2-in-1 robot vacuum and mop featuring Smart Navi 3.0 laser mapping technology, a 430ml dustbin, a 240ml water tank, and a 3,200mAh battery that delivers up to 110 minutes of runtime. Key pros include its multi-floor mapping capability for storing up to two distinct layouts, automatic carpet detection that doubles its 1,200 Pa suction power on soft surfaces, and a low-profile 93mm height designed to easily slide under low furniture. However, notable cons include its sub-par mopping depth compared to dedicated units, a relatively small battery capacity for very large properties, and occasional software bugs within the companion application.
