The latest trend in robot vacuum cleaners is the use of a washing or cleaning roller, a feature inspired by traditional stick vacuum cleaners. Ecovacs, a leading brand in the field, was among the first to adapt this technology, initially using it in high-end models like the Deebot X8 Pro Omni before introducing it in more affordable models like the Deebot T80 Omni. In response to this innovation, Mova launched its first robot vacuum with a roller, the Z60 Ultra Roller, last year. However, it was found to be less effective than its competitors, especially given its premium positioning. As a result, Mova reworked its design and introduced the S70 Ultra Roller at CES 2026. Priced below 700 euros, the S70 Ultra Roller aims to bring roller cleaning technology to a broader audience. The key question is whether it truly offers top-tier performance at a budget-friendly price or if it sacrifices too much to keep costs low. The Mova S70 Ultra Roller features a refined and minimalist design, a notable improvement from earlier Mova models that were often criticized for their unattractive look and basic features. The base includes two water tanks: 5 liters for clean water and 4.5 liters for dirty water, both integrated into the body of the station. These tanks come with handles for easy transport and are highlighted by a gold-colored insert, adding to the product’s sleek appearance. A removable cover on the front conceals a 3.2-liter dust bag and a detergent reservoir. Unlike Mova’s more expensive models, this one has a single compartment, making it less adaptable for different floor types like wood and tiles. The cleaning roller, fully removable and located at the bottom of the station, is designed for easy cleaning. The robot itself has a classic circular shape, but its design is more refined. On the upper part, two quick-access buttons do not hide a sensor. Mova has replaced the traditional LiDAR dome with a laser dToF (direct Time-of-Flight) sensor, fully integrated into the front of the robot. This design, supported by two metal bars, gives the robot a futuristic look. Below this, a trio of 3D and LED sensor cameras helps with positioning and obstacle detection. This setup allows the robot to maintain an ultra-thin profile of 9 cm, enabling it to easily navigate under low furniture. The bottom of the robot features a 27 cm cleaning or washing roller that can extend laterally by 4.4 cm. The S70 Ultra Roller uses a rubber brush roller with integrated blades to cut pet hair and prevent tangles. The side brush is extendable, allowing the robot to reach dust in corners and tight spaces. The build quality appears solid, though the plastics used are not overly thick, which aligns with the robot's mid-range positioning. The Mova app is rich in customization options, making it user-friendly. During setup, the app helps connect the robot to a WiFi network and guides the user through the initial mapping process. The robot uses its sensors to recognize and name different rooms, though it may occasionally misidentify spaces like a kitchen as a dining room. Once the map is created, users can edit it, rename rooms, set cleaning sequences, and define virtual walls. The app also allows for personalized settings, such as adjusting suction power, mop water levels, and the frequency of mop cleaning. The CleanGenius mode automatically adjusts cleaning parameters based on floor type and dirtiness, but users can also adjust these settings manually for greater control.
