Regarding your lawn size, while a 250 square metre lawn could technically be handled by the Mini 500, you might actually want to consider the YUKA Mini 600 instead. Here's why:

- Less frequent charging: The larger battery capacity means fewer charge cycles, which reduces wear on the battery over time
- Less strain on the battery: Working closer to a battery's capacity limit puts more stress on it, whereas the Mini 600 would handle your lawn with ease
- Better long-term battery health: Running at a more comfortable capacity typically extends overall battery lifespan
- Future-proofing: If you ever need to cover additional areas or have irregular lawn shapes that require more coverage, you'll have the capacity

Regarding iNavi: Yes, the current YUKA Mini range does come with iNavi navigation technology.

Kind regards
