Roborock S7 Max Ultra

The Max Ultra and the Pro Ultra both offer excellent cleaning capabilities, but there are some key differences to consider. The Max Ultra is slightly heavier at 12.3 kg compared to the Pro Ultra's lighter 4.8 kg, which might matter if you need to move it often. In terms of noise level, the Pro Ultra is slightly louder at 68.5 dB compared to the Max Ultra's 67 dB, which may be noticed in quieter settings. Furthermore, while both have self-docking and app control features, the Pro Ultra has the added advantage of being specifically adapted for pet owners and has double side brushes for more efficient cleaning. The charging time is a notable distinction as well, with the Max Ultra taking 4 hours to charge compared to the Pro Ultra's longer 6-hour charging period.
