• 🤖 Mi Robot Vacuum-Mop P (STYTJ01ZHM) — Requires unlocking the bootloader through Mi Home.
• 🤖 Dreame D9 / D10 — They are running through DreameHome, but a modified version of the software is needed.
• 🤖 Viomi V2 / V3 — Compatible with Xiaomi firmware, but there may be problems with sensors.
• ❌ Mi Robot Vacuum 1S / 2C — closed loader, flashing is impossible without a soldering iron.

For models from 2023 to 2026 (such as the Xiaomi Robot Vacuum-Mop 2 Ultra), the process is complicated by the Secure Boot protection, and their firmware requires additional manipulation of the Mi Home server or the use of workarounds through the Mi Home server. ADB.
