Which STM32 MCU would be suitable for a smart commercial floor-cleaning machine?

[floorcleaning]

Hello,

I am exploring the possibility of developing a smart floor-cleaning machine for commercial environments.

The initial concept may include:

• Motor control for brushes and wheels
• Water-level and pressure sensors
• Battery monitoring
• Obstacle detection
• Bluetooth or Wi-Fi connectivity
• Basic usage and maintenance logging

My background is in the floor-cleaning industry rather than embedded-system development. Our current business website is https://floorcleaningsydney.com.au/, which provides context about the types of floor-cleaning work and environments the machine may be used in.

Which STM32 MCU family would be a practical starting point for this type of prototype?

Would an STM32G4 be appropriate because of its motor-control features, or would another STM32 family be easier for an initial prototype?

I would also appreciate recommendations for a suitable STM32 development board and motor-control expansion board.
