Robotic cleaning is attractive because it cuts water and labour, but it also adds something the original mounting structure may never have been designed for: a heavy, moving load that sits on the modules and rails.
The robot's weight is only the starting point. What matters is how that weight reaches the structure.
Why the headline weight is not enough
A robot can load the array through wheels, tracks or discrete contact points. A wheel that lands midway between supports produces a different response from the same weight spread along a row. Start-stop motion, travel path, parking positions and maintenance loads add further effects, so ask the supplier for contact geometry and operating limits for the specific model, not a brochure figure.
Compatibility is not only about strength. Rail geometry, clearances, deflection, vibration and alignment with module edges all decide whether the robot can run without damaging the array or itself.
- Obtain model-specific loads, wheel layout and installation requirements.
- Confirm contact positions, travel route and parking locations.
- Check clearances, local member effects and support spacing.
Following the load through the existing structure
The review should trace the added actions from rails to secondary members, primary frames, connections and foundations. If original calculations or drawings are missing, say so and decide what measurement, inspection or testing will fill the gap. If reinforcement is needed, check the method against the existing structure and the installation sequence.
Hold procurement until the structural interface is understood. A similar-looking replacement can have different contact geometry, so equivalence should be verified rather than assumed.
- Compare the robot data with the actual mounting system.
- Document any reinforcement or operating restrictions.
- Record approvals and manufacturer constraints.
- Reassess if the equipment is ever substituted.
