Spectra S1 vs S9: Differences
Let’s dive in a little deeper about the difference between Spectra S1 vs S9 Plus breast pumps.
The Spectra S1 Plus is considered a hospital-grade pump because it can be used by other women (provided they have their accessories) and also because of its powerful motor.
The Spectra S9 Plus though is not a hospital-grade breast pump. It has a less powerful motor plus you can’t share or rent this to other people.
Motor (Suction Power)
The Spectra S1 has a powerful pumping motor, allowing you to pump less for more milk.
Its suction rate goes up to 270mmHg.
It has some complaints though about its weakening suction power after using it only for only several months.
The Spectra S9‘s suction in comparison can be adjusted to a maximum of 260mmHg.
But its suction power has also some complaints and mixed reviews about how they can’t empty their milk while using the S9.
Built-in LED Light
The Spectra S1 has a night light with 2 modes, which is convenient to have especially when you’re pumping the dark.
The Spectra S9 Plus doesn’t have a night light but it does have a backlit display.
The Spectra S1 can remember your last pumping mode, which is an awesome feature to have, so you don’t need to keep on adjusting the setting at the start of every pumping session.
The Spectra S9 Plus doesn’t have that feature though, so it can be a little bit of a hassle to keep on adjusting to your preferred setting.
The Spectra S9 Plus is very easy and convenient to bring on travels and vacations, as it’s very light and portable, weighing only .5 lbs or 0.23kg.
While the Spectra S1 Plus weighs at 3 lbs or 1.36078 kg, way heavier than the S9.
The shape and color are obviously different between these two, with the Spectra S1 having a more heavy-looking design, while the Spectra S9 has a sleeker and slender look.
The Spectra S1 Plus is slightly pricier than the Spectra S9 Plus.
Which can be worth the price, given that the Spectra S1 has a more powerful motor than the Spectra S9.
Similarities of Spectra S1 vs S9
Now let’s take a more detailed look at the similar features of the Spectra S9 vs S1 Plus breast pump
Both the Spectra S1 Plus and Spectra S9 Plus have a built-in rechargeable battery, allowing you to pump on the go, anywhere.
You can also use both pumps while plugged.
You can fully charge the Spectra S9 Plus for 3 to 4 hours, which will give you a pumping time of at least 2.5 hours.
The Spectra S9 Plus can also be charged in your car using its 9-Volt Portable Car Adapter.
The Spectra S1 Plus, on the other hand, charges fully for 3 hours and its battery lasts a bit longer than the Spectra S9, at 4 hours.
Both the Spectra S1 vs S9 Plus have very gentle suction and according to most users, both are more comfortable to use compared to other brands.
Both the Spectra S1 vs S9 are closed system breast pumps, meaning they each have a backflow protector – a barrier that ensures milk doesn’t go up the tube and into the motor, for safety and hygienic purposes.
Both the Spectra S1 vs S9 have the same voltage of 100V-240V / 50-60Hz, which allows you to use it in another country, with the help of a travel adapter.
Adjustable Pumping Mode
Both the Spectra S9 Plus and S1 Plus have 2 adjustable pumping modes – Massage and Expression mode.
The Massage mode is initially used to stimulate a letdown while the Expression mode is used for regular pumping or after the Massage mode.
For the Spectra S1 Plus, the Massage mode’s suction can be adjusted from level 1 to 5.
Its Expression mode suction can be adjusted from level 1 to 12 and has 5-speed settings.
The Spectra S9’s Massage mode can be adjusted from level 1 to 5.
Its Expression mode is from level 1 up to level 10.
But the Spectra S9 doesn’t have any speed settings, which means you can’t control how fast or slow the pumping mode can be.
For some moms, these personalized settings can be quite heaven-sent, as you can adjust the suction strength to mimic your baby’s nursing.
However, some new moms might find the level and range of settings overwhelming.
If you just want to pump at the quickest time possible and it’s your first time, you have to keep on adjusting the pumping settings, until you find the setting that works best for you.

Both Spectra pumps automatically turn off after pumping for 30 minutes.

That means you can ask away any questions you have about nursing, pumping, or even caring for your baby by just setting up an appointment and talking to one of their lactation consultants.
