Xiaomi Roborock Robot Cleaner S5 — A reliable cleaning assistant, but even the most advanced equipment sometimes needs to be rebooted. S5 There are three types of reboot: soft reset (reset), hard reboot (forced reboot) and full factory reset.

Before embarking on a reboot, it's important to understand whether it's really necessary. - Roborock S5 — It's a smart device with its own operating system, and sometimes its brakes are not due to hardware problems, but to software failures:

- 🔋 Inadequate battery behavior – quickly discharges, fails to charge to 100% or shows an incorrect charge level.
- 📱 Mi Home app crashes – no commands from the app are executed, vacuum cleaner status is not updated.
Most often these problems arise due to:
- 🖥️ Software glitches after firmware update.
- 📡 Conflicts with the router (for example, when changing the Wi-Fi password).
- 🔌 Unstable power during charging.
- 🧹 Overheating after prolonged cleaning.
⚠️ Warning: If the robot is making uncharacteristic sounds (squeaking, knocking) or not rotating brushes, the problem may be mechanical.
