Spectra S2 vs Medela Pump: Comparison

spectra s2

Pump Type

Spectra S2 is a hospital grade pump, which means it has a heavy duty motor and is able to be used by multiple users (with new attachments parts, like tubing and flanges). This pump can also be used multiple times a day without stressing the motor. The S2 also comes as a double electric breast pump but you can also easily use it as a single pump.

On the other hand, theMedela Swing Maxi Double is a portable double electric pump. The motor is not the heavy duty strength and durability of the S2, but it does have the exta feature of being portable, with a rechargeable battery.

Older versions of the Medela Swing only offered single breast pump capability, but the new Medela Swing Maxi Double is now a double electric breast pump.

If you prefer a single electric breast pump, Medela also offers the Solo Single Electric Breast Pump which is the same as the Medela Swing Maxi Double but in a single version. This can be cost effective.

The Medela Swing Maxi Double is the upgraded version of the Medela Swing Maxi Flex, which is almost exactly the same, except the new Medela Swing Maxi Double is rechargeable, while the Medela Swing Maxi Flex required 6xAAA batteries to be portable.

Weight and Portability

The Spectra S2 breast pump is a lightweight product and weighs 2.9lbs pounds. You also need to plug this device in the wall before using it.

But Medela Swing Maxi Double takes things to the next level because it weighs only 325g, which is less than a pound. Is it also rechargeable with a USB cable, making it highly portable.

Safety Features

Spectra S2 transfers milk straight to the bottle from your breast, thanks to its closed system. Resultantly, it keeps the breast milk from going through the tubing. It makes the breast pump more hygienic and you won’t need to clean this breast pump between pumping sessions.

Spectra S2 also comes with backflow protection that prevents the breast milk from going into the motor

Medela Swing Maxi Double is also a closed system breast pump, which prevents milk from entering the tubes and the motor.

Having a closed system pump is important because it’s really hard to clean milk from the tubing that leads to the motor, which is unhygenic. Without a closed system pump, you also run the risk of milk entering the motor which will ruin your pump.

Luckily, both of these pumps are closed system!

Runner Up
Medela Breast Pump | Swing Maxi Double Electric | Portable Breast Pump | USB-C Rechargeable | Bluetooth | Closed System
  • INCREASED MILK OUTPUT: Express 18% more milk* than a traditional single pump thanks to our 2-Phase Expression technology that simulates baby’s natural sucking pattern

The bottles, breast shields, flanges, and tubing of both breast pumps are made of BPA free plastic materials for your baby’s safety.


Spectra S2 offers three different settings that you can use.

  • Cycle speed
  • Vacuum strength
  • Massage mode/expression mode

This breast pump also comes with an LCD screen with a timer, night light, and push buttons to activate different settings.

On the other hand, Medela Swing features 2 phase expression technology and provides you with a one touch let down mode. You can also choose a maximum comfort vacuum setting if you want faster milk expression. Unfortunately, you don’t get an LCD screen, timer, or night light with Medela Swing.

The vacuum and strength settings are not able to be changed independently, so as you increase the speed, you also increase suction strength.

Suction Power

Spectra S2, being a hospital grade breast pump, offers the maximum suction power of 270 mmHg. You can also choose from 12 different suction levels so that you can select the most comfortable option to express breast milk.

Medela Swing isn’t a hospital grade pump and its maximum suction power is up to 245 mmHg.


Both of these pumps are quiet at just 45db at the maximum vacuum level, which is similar to the noise level in a library.

Accessories and Features Included

It’s one of the areas where Spectra S2 lacks as it doesn’t come with any cooler or a bag. You’ll need to buy Spectra S2 Plus Premier to get some extra bottles, a cooler, and a bag. The standard Spectra S2 package, however, comes with a couple of wide-neck bottles, one 12V AC adapter, tubing, two backflow protectors, two 28 mm flanges, two 24 mm flanges, and duckbill valves.

I’ve linked up the full package in all of the links on this page, but if you would prefer just the pump without any of the optional accessories, here is that package.

Medela Swing Maxi also doesn’t offer a cooler bag and if you need one you might like to buy a breast pump carry bag.

Ease of Use

Medela Swing comes with one touch let-down button and different buttons to select your preferred settings for comfort and faster milk flow. You’ll need to tweak it manually each time as it can’t store your settings.


The Spectra S2 is quite a bit cheaper than the Medela Swing Maxi Double, even when looking at the full package with bag and cooler included.

Spectra s2 vs Medela Maxi Double: Pros and Cons

Spectra S2

What we love

  • Hospital grade breast pump
  • Comes with a closed system
  • Lower priced
  • Offers display screen
  • Quitter operation than Medela Swing
  • Offers both expression and massage mode
  • Comes with separate buttons for vacuum speed and suction

What we don’t

  • Doesn’t offer a battery option
  • A bit heavier than Medela Swing

Medela Swing Maxi Double

What we love

  • Extremely portable
  • Comes with a battery pack
  • Flanges and breast shields are separable
  • Comes with a closed system

What we don’t

  • More costly than Spectra S2
  • No separate adjustment option for vacuum speeds and suction speeds
  • Doesn’t have a digital display


Overall, we think that the Spectra S2 is a better all-around breast pump than the Medela Swing Maxi. However, there are a few situations where you might prefer the Medela.

  • You need it to supplement a second pump
  • You are going to be pumping away from home and need a rechargeable battery
  • You aren’t concerned about usability
  • You don’t need hospital grade features

Overall, we recommend the S2. It’s slightly cheaper, but is hospital grade and can be resold after use.

If you are after a hospital grade pump with a rechargeable battery, it is worth looking at the Spectra S1, which is the battery version of the S2.

However, if you just need a breast pump that’s easy to carry and can run on battery, then the Medela Swing breast pump is still a great breast pump and made by a reputable company.
