The word walis means broom or to sweep.
Tingting refers to the thin sticks that are bundled together to make this broom.
In fact, the word “tingting” is often used to describe a very thin person, sort of like how “thin as a reed” is an idiomatic expression in English.
For smoother surfaces, Filipinos don’t use a walis tingting but instead a walis tambo.
You can buy a walis tambo online in the Amazon marketplace!
