The Problem with Random Patterns
First-generation robots moved randomly, covering 70–80% of the glass per cycle. Missed strips. Streaks. Multiple re-passes required.
How CleanBot R1 AI Path-Mapping Works
The robot scans the window first — mapping dimensions, edges and obstacles — then selects the optimal algorithm from three options.
N-Shape
Vertical sweeps. Optimal for tall narrow windows — sash, floor-to-ceiling panels.
Z-Shape
Horizontal sweeps. Optimal for wide low windows — bi-fold doors, picture windows.
Hybrid N+Z
Combined passes for large or irregular surfaces. Selected automatically above a surface area threshold.
Result
100% surface coverage in 47 consecutive test sessions. Zero missed strips. No re-passes required. Streaks eliminated because consistent overlapping paths deliver uniform moisture and pad pressure.
