Overview

The S20 Ultra is a 2024 MOVA all-in-one dock robot with a vibrating mop pad instead of spinning pads, and it is on the Valetudo list with relatively easy rooting that leaves warranty seals intact. In October 2026 MOVA US offers it only as a refurbished unit, and Amazon had no new stock, so new buyers are steered to the S70 Roller, a slim 90 mm roller-mop robot that is not rootable. For a rootable MOVA still sold new see the P10 Pro Ultra.
