The Roomba Plus 505 Combo is a premium robot vacuum from iRobot with powerful suction, a mopping function, and smart obstacle detection. Its design is similar to the 405 and is available in black and white. Due to its LiDAR unit and camera, it is slightly taller, making it challenging to navigate low furniture. The AutoWash dock empties the dust bin, cleans and dries the pads, and supplies the robot with fresh water. The transparent reservoirs are less aesthetically pleasing, but functional.
In use, the robot navigates accurately and reliably detects obstacles such as cables and shoes. Up to 7,000 Pa of suction effortlessly removes dirt and pet hair. Only deep-pile carpets are challenging. The rotating mopping pads with PerfectEdge reach right up to the baseboards and clean effectively, but can sometimes be too wet—the water level is not adjustable, despite marketing promises.
The app lacks integration with older models and is slow and sometimes error-prone. You can, however, see live where the robot is and what it's doing. Settings aren't always logically placed, and some features like No-Go Zones are missing.
In short, the 505 Combo offers plenty of comfort and technology, but it also has some quirks. Those who can live with those will get a smart and powerful robot that's especially well-suited for busy households.
