Office cleaning robots: calculating the real return on investment

A robot vacuum cleaner can reduce the cost of regularly cleaning large areas, but it rarely replaces an entire team or service. Most often, one part of the process takes over: nightly vacuuming, scrubbing the corridor or maintaining a repeatable route. Therefore, the payback should be calculated based on the hours actually saved, not the entire cleaning budget.

Step 1: describe the process before the robot

Record area, frequency, number of hours worked, total rate and additional activities. Separate floor cleaning from emptying bins, cleaning toilets, corners and surfaces above the floor.

Step 2: measure autonomy, not just speed

The declared number of square meters per hour does not include blocking, charging, water refilling and trips to the station. In the pilot, measure:

• number of missions completed without intervention,
• actual covered area,
• robot preparation and cleaning time,
• number of downtimes,
• result quality and number of corrections,
• service response time.

Step 3: Calculate the total cost

Add financing, installation, mapping, materials, energy, parts, inspections, connectivity and operator time to the price or subscription. If a device requires an employee to spend 30 minutes a day, this is a real cost, even if it does not appear on the supplier's invoice.

Example model

Let's assume that the robot including implementation costs about €20,000 and is to be used for five years. A simple division gives about €4,000 per year, but you have to add service, materials and the cost of capital. If the annual total cost is about €6,500 and the device takes on work worth about €10,000, the potential gross benefit is about €3,500. Only then do you need to take into account the risk of failure and quality.

The robot should not be compared to the employee's net salary. The correct point is the total cost of the activity - including absenteeism, management and equipment - but only for the work that the robot actually takes over.

Purchase or RaaS?

The subscription reduces the initial outlay and may include service and a replacement device. Purchasing gives you more control, but transfers the risk of residual value and failure to the company. For the first implementation, a paid pilot or a contract with the option to exit may be reasonable.

When is the robot in the best conditions?

• large and regular surface,
• ability to work outside busy hours,
• few thresholds and random obstacles,
• frequent, repetitive cleaning,
• local service and quick device replacement.

Cost of quality

If the robot requires frequent corrections, time savings are reduced and user dissatisfaction increases. The indicators should include not only the surface area, but also the number of complaints, the result of the cleanliness test and visible traces of work.

Change in work organization

The robot can perform flooring at night, and the staff can focus on sanitary facilities and details. The project should include training and a new division of tasks. Automation without changing the schedule often does not provide the full benefits.

Data Value

Some systems report area covered, time and errors. Data can help control an external service, but only if it is reliable and available for export.

Conditions of the pilot agreement

• specific route and number of test days,
• success criteria,
• cost and cancellation policy,
• liability for damages,
• service response time,
• final report with meters.

RoboMorrow Evaluation

A robot pays off when it reduces a specific number of man-hours with acceptable quality and a low number of interventions. The promise of "cleaning automation" without pilot data is not sufficient for an investment decision.
