20 vintage photos of products that show how far we've come in the last 100 years

• The 20th century saw some of the most important inventions that have shaped our world today. 
• Some appliances that were invented include the vacuum, the air conditioner, and the blow dryer.
• The television, the computer, and the cell phone were also invented in the 1900s. 
• But none of the inventions look like what we are used to today. 

The 20th century brought us some of the best inventions in history, including major feats like the personal computer and the first vacuum. 

But looking back at these inventions, each one has dramatically changed over the years. While some of the technologies were made for the kitchen and some for the office, all of them look completely different today compared to when they were first invented. 

Take a look at some of the inventions to see how far we have come. 

Before the invention of the vacuum, people would clean the floors with brooms and mops.

The idea for a vacuum can be traced back to the mid-1800s, when inventors created rotating brushes attached to wheels for easier cleanup. They continued to create more innovative devices to alleviate the work of sweeping, which eventually led to the electric brush in 1911.

The original vacuum cleaner was invented in 1901.

The original vacuum wasn't the most well thought out idea. An inventor named Hubert Booth decided to clean railway carriages by blasting the furniture with compressed air. Of course, once blown out, the dust would settle right back on the furniture.

By 1908, the vacuum cleaner looked more like what we are used to today.

In 1908, the vacuum was redesigned to use suction and capture the dust in a bag. The design was sold to the Hoover company, which still operates today. Vacuums come in all shapes and sizes these days, but the most advanced is the Roomba, which cleans the floors by memorizing the layout of your home.
