1. Establish ownership and transfer before collection.
Ask how the seller obtained the mower and whether it is linked to their account. Where the seller controls the original account, use the manufacturer’s normal transfer process. Mammotion’s account-change guidance says to unbind the device before adding it to a different account. Keep the purchase record. Do not assume a factory reset or a receipt will resolve every binding condition.
2. Make a complete accessories list.
Write down exactly what is included: mower, charging station, power supplies, cables, positioning equipment and any model-specific accessories. Photograph labels and connectors. Missing hardware can change the value of a deal substantially, and a similar-looking power supply is not proof of compatibility.
3. Separate cosmetics from function.
Scratches and shell wear are one question; charging, drive, sensing and navigation are another. Ask for known repairs, water exposure, impact damage and storage history. Review the battery disclosures and how any runtime statement was measured. A claimed age is different from a measured condition.
4. Ask for a meaningful demonstration.
A startup screen proves less than an appropriate functional demonstration. Ask what was tested, on what date and under what conditions. Look for charging, movement and an explanation of positioning and setup behavior for that model. Keep clear of moving blades and follow the manufacturer’s operating guidance during any demonstration.
5. Price the complete ownership path.
Add missing accessories, transport, installation, likely repairs and the seller’s actual return terms to the headline price. If the mower remains account-bound, determine the legitimate transfer route and exact eligibility before treating it as usable stock. Account recovery and hardware repair are separate expenses and separate outcomes.
When UnlockMyBot may help.
UnlockMyBot provides a defined remote account-unbinding service for eligible, lawfully owned Mammotion devices. It does not establish hardware health, repair a mower or guarantee every unit is eligible. Review the supported models, requirements and current service terms before buying around that assumption.
Buy a documented machine and a clear transfer path—not just a reassuring power-on video.
