How do window washers reach the 60th floor?

Video · 1:52 · Crafty Clover explains, from A Million Whys Book 25

Window washers ride on platforms that hang from cables attached to a rig on the roof. They wear safety harnesses connected to strong anchor points. Some buildings have tracks and machines that move up and down the glass. Washers clean with soapy water and squeegees. They do not work when it is windy or stormy, because safety comes first.

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How do window washers reach the 60th floor?

The Big Idea

Who cleans the windows on the 60th floor? Brave, well-trained window washers! Let's see how they stay safe.

Platforms

Step one: Platforms. Window washers ride on platforms that hang from cables attached to a rig on the roof. The platform moves up and down the building.

Harnesses

Step two: Harnesses. They wear safety harnesses connected to strong anchor points. Some buildings have tracks and machines that move along the glass.

Cleaning

Step three: Cleaning. Washers clean with soapy water and squeegees. They do not work when it is windy or stormy, because safety comes first.

A Closer Look

Let's take a closer look! A roof rig holds the cables. Cables lift the platform. A harness keeps them safe. A squeegee cleans the glass.

Quick Facts

Quick facts! Some buildings now use drones and robots to help clean. No work on windy days. Washers train carefully. Washing all the windows on a big tower can take weeks.

Think Like a Scientist

Now, think like a scientist! With a grown-up, squeegee a ground-floor window. Clean one half with soapy water. Clean the other half with plain water. Which half looks cleaner? Never lean out of an upper window.

Outro

Window washers reach high floors on platforms hanging from roof rigs, clipped into harnesses at strong anchor points. They clean with soapy water and squeegees, and never work in wind or storms. Science is amazing! Remember, every big discovery starts with a small question. Keep looking, keep learning, and keep asking why!
