Cleaner with a walk-behind autoscrubber vs Autonomous floor scrubber
Estimativas modeladas pela Whirrwork, não fatos. Metodologia · Histórico de acertos
On these numbers it is close: decide on the things that are not cost. The robot would sit idle most of the time; it pays off at higher volume or longer hours. Payback is longer than three years, which is longer than many robot contracts and some robot companies.

What the spreadsheet misses
- Segurança
- Fewer slips while floors are wet if the robot cleans after hours; a 300 kg machine near shoppers needs working sensors and sensible routes.
- Qualidade
- Robots are consistent on open floor and log what they cleaned. They miss edges and spot spills unless someone follows up.
- Flexibilidade
- A cleaner handles bathrooms, bins and the unexpected; a scrubber scrubs.
- Edge cases
- Cluttered, changing layouts (pallets left in aisles) kill robot productivity fast.
- Customer experience
- Usually neutral to positive in stores; noise at night is a non-issue.
- Jobs and redeployment
- The common pattern is redeploying cleaners to detail work rather than cutting hours one-for-one; plan the redeployment before the robot arrives.
- Regulamentação
- No licence needed. Check lease terms for damage liability.
