I have a brand new unused 2024 (replacement unit) S1+ M1 and a 2023 yarbo unit (right track motor fail) S1+M1 (modules and parts working)
2024 yarbo core + Snow module + lawn mower module brand new and works out of the box.
2023 yarbo core unit has a failure in right motor track. One could fix it and get it to work. Snow blower and lawn mower module still work. Lawn mower module has new blades.
Pick up only from Plymouth county MA.
