ROI Comparison
Same operating assumptions across every robot — the only difference is price. Set your numbers once to see which pays back fastest.
Annual labor displaced (per robot): $50,000
| Metric | Walker S1 | Xiaomi CyberOne V2 |
|---|---|---|
| Investment | $75,000 | $150,000 |
| Payback period | 18.0 mo | 36.0 mo |
| Net savings (5 yr) | $175,000 | $100,000 |
| ROI (5 yr) | +233% | +67% |
Estimates labor-cost displacement only — not a full total cost of ownership. Actual ROI depends on integration, maintenance, training, downtime, and task fit. Converted currencies are indicative; USD is the price of record.
