A second round of testing was conducted using 120 grams of baking soda. The soil was spread across 40 square feet of floor tile (3 grams per tile). The Qleeno unit was operated on lowest water output, medium water output, and high-water output all with highest water suction.

Methods Evaluated: Qleeno; Mop

After cleaning, baking soda left behind a residual of white streaks. Higher flow helped in reducing the streaking. The wet mop was by far the least effective at cleaning the fine particles from the surface. The high flow with high suction was the fastest and most effective cleaning method evaluated. The medium flow had nearly the same collection efficiency but required a little more time to complete the provided area.

The use of Qleeno with the settings on medium flow and high flow both on high suction was effective in removing soil from the floor with an 85% efficiency and around 1 minute of cleaning for the 40 square feet.
