Layer 1: 6,500Pa Gravity-Lock Suction
Same suction force used in industrial vacuum lifters that hold 80kg glass panes. Creates a holding force many times the robots 1.1kg weight.
Layer 2: 500mAh Backup Battery
Maintains full suction for 30 minutes if mains power cuts. No other robot in this price range has independent power backup for suction.
Layer 3: Suction Alarm
Pressure sensors monitor grip continuously. Alarm triggers before any movement risk if grip weakens.
Layer 4: 150kg Safety Tether
Mechanical last resort connected to window frame. Has never been the thing that caught a robot — suction handles it. But it is there.
Layer 5: Four-Corner Infrared Edge Detection
Detects window edges, frames and handles on all four corners. Will not drive off the edge of the glass.
Layer 6: Obstacle Avoidance
Routes around frames, trickle vents and fixtures in real time.
Layer 7: Gyroscope Stabiliser
Corrects tilt up to 10 degrees. Keeps suction seal flush on thermally expanded glass.
Layer 8: High-Friction Silicone Pads
Secondary friction contact independent of the suction motor.
