Verdict

The iRobot Roomba Combo R111840 is a 2-in-1 robot vacuum and mop designed for hard floors and carpets, featuring a 450 ml dust bin capacity, 3.22 kg weight, and a compact 8.2 cm height that helps it clean under low furniture. It utilizes logical row-by-row navigation, a V-shaped brush roll, dual vacuuming modes, and a microfiber mopping pad supported by three customizable washing modes. Main pros include its efficient surface cleaning, ease of use via app and voice controls (Alexa and Google Assistant), and the ability to vacuum and mop simultaneously. However, notable cons include its outdated NiMH battery technology, occasional difficulty returning to the charging dock, and the lack of advanced smart mapping or customizable keep-out zones.
