Close call. D1 and BellaBot Pro trade wins across the matrix.
Readiness, uptime, navigation & connectivity
Price accessibility and ROI clarity
Payload, speed, runtime & labor replacement
Environment fit, footprint & long-term upside
Multi-floor security patrols in facilities with stairs, slopes, and cluttered outdoor perimeters (warehouses, construction sites, utility substations)
Large 100–200 seat casual-dining chains during dinner rush—reduces server travel time, enabling 1–2 additional table turns per evening at $150/check.
Both are credible picks. Decide on cost and supplier proximity, not capability — the gap is small.
