Weight and Portability

The Spectra S2 Plus weighs only 3.3 pounds making it a very lightweight breast pump that you can easily carry while traveling. However, it doesn’t come with a rechargeable battery and you’ll need to plug this pump into a wall outlet to start pumping. The package comes with an AC adapter to power the pump

Medela Freestyle Flex on the other hand comes with a USB rechargeable battery that keeps you from going into the hassle of buying a battery pack again and again. It also allows you to use the pump while traveling.

Because of the additional battery and multiple bottles, it weighs 5.09 pounds making it heavier than Spectra S2. You also get a USB cable and power adapter with your package to charge the built-in battery.

Settings and Modes

Spectra offers the following three different modes in the S2 model:

  • Vacuum strength
  • Cycle speed
  • Massage or Expression mode

You can select these settings by using the available buttons. Spectra S2 also features an LCD screen that provides you with all the information about the selected settings. Other than that, it also offers a timer option and night light for convenience.

Medela Freestyle Flex comes with a modern design and offers a digital touchscreen LED display to select the desired setting. It also flaunts a night light and timer option. You can also connect it to the Medela Family App to automatically track your pumping sessions.

Safety Features

Spectra S2 comes with a closed system to keep the milk from reaching the pump’s tubing. Not only does it make the pumping experience more hygienic but it also makes it easy to clean. This electric breast pump is also equipped with backflow protection to prevent the milk from reaching the pump motor.

Medela Freestyle Flex also comes with a closed system and overflow protection that eliminates the chances for milk backflow. It also allows you to use the pump in any position you want.

All the components of both breast pumps including flanges, breast shields, and tubing are made of BPA-free materials for enhanced safety. Both the companies offer replacement parts to purchase if you need and they are also BPA-free.

Ease of Cleaning

Spectra S2 not only offers hospital grade performance, but it’s also very easy to clean. It comes with built-in memory to store the preferred settings that you can select on the go. The fewer pump parts also make this breast pump super easy to clean and it also offers quieter operation than Medela Freestyle Flex.

Medela Freestyle Flex is also simple and easy to clean as you only need to separate three different parts that include the connector, membrane, and breast shield. You can use a dishwasher or hand wash all the parts except tubing for cleaning.  

Tip: It’s advisable to wash all the components after each pumping session.
