Reality check
A demo shows what may be possible. These points help judge whether the product fits day-to-day use.
Works well when
- Predictable delivery, cleaning or guidance routes
- Sites with elevators, doors and handoff rules defined
- Repetitive work where staff can handle exceptions
What to check
- Navigation around guests, children and temporary obstacles
- Charging, cleaning and refilling requirements
- Actual handoff behavior when the route is blocked
Not a magic solution
- A substitute for hospitality and human judgment
- A guarantee of lower labor cost without workflow changes
- A safe choice for an untested public environment
