The video shows a man wearing a face mask and blue gloves driving a large, blue floor scrubbing machine through a tunnel. The machine has the name "TENNANT" on the front and "T17" on the side. The tunnel has a brick ceiling with recessed lighting and a tiled floor. The machine has flashing red lights on the back, and is leaving a streak of clean floor behind it. The man steers the machine as it slowly progresses through the tunnel.
