Strap keeping nozzle skirt taut for better sealing.

Acoustic silencer reducing overall sweeper noise levels.

Sensor detecting surface dampness before line marking or binder spraying. Prevents wasted material on non-adhesive wet substrates.

Gauge showing skirt wear limits.

Small roller at the front of the suction head that follows surface contours. Prevents the head from digging into uneven tarmac.

Field test using graded sand to determine macro-texture depth. Required on UK trunk-road surface-dressing sites to verify skid resistance.

Individually controlled valves for neat start/stop of spray lanes.

Heavy-duty clip securing flexible suction hoses to duct flanges. Stops vibration-related leaks under high vacuum pressure.

Fixed points used to align long lines.

Valve isolating bar for maintenance.
