Below is a more detailed info on the differences between the Baby Buddha vs Spectra S9.

Baby Buddha vs Spectra S9: Differences

Let’s dive in a little deeper about the difference between Baby Buddha vs Spectra S9 Plus.


Both the Spectra S9 vs Baby Buddha has a built-in rechargeable battery, which means you can use it without having to plug it into a socket.

If however, you’re running out of battery, you can plug both breast pumps and pump away!

The Spectra S9 can be fully charged for 3 to 4 hours. When fully charged, it allows you to pump for up to 2.5 hours.

You can plug the Spectra S9 into your car charger, using its own 9-Volt Portable Car Adapter. that comes with the breast pump set.

The Baby Buddha, on the other hand, needs 5-6 hours for its first charging time then a maximum of 4 hours every other time. 

Charging it fully will give you approximately 1 hour of pumping or at least 4 to 5 pumping sessions. Just don’t overcharge its battery so you can use its battery life usage of 800-1000 hours of pumping.

You can also use and charge the Baby Buddha at the same time via a micro USB car plug while you’re driving. The micro USB cable is just a simple one that you can easily replace it if you lose it.


The Baby Buddha is a tad more expensive than the Spectra S9 Plus.

Which I think, is worth the price, given that the Baby Buddha’s suction power is so much stronger than the Spectra. Plus it’s so much smaller too!


Baby Buddha is usually covered by your insurance but just to be sure fill-up the form in this link to kickstart the insurance process and confirmation.

For the Spectra S9, check here if your insurance covers the said breast pump.

Suction Strength

The Spectra S9 Plus suction can be adjusted to a maximum of 260mmHg and at Level 10.

Its suction power has a mixed review, with some moms saying it’s powerful enough for them, while some are saying they can’t get empty out their milk using this pump.

In contrast, the Baby Buddha’s maximum suction mode is at 307.5 mmHg which is higher than the Spectra S9.

A lot of moms actually commented on its powerful suction, which most said is stronger than Spectra’s and can empty out their milk every time.

However, that suction strength is also a disadvantage, as most moms complained that it’s too painful at times, even if it’s only at the lowest setting.


Spectra S9 has a very gentle and comfortable suction compared to other brands. Most especially compared to the Baby Buddha breast pump.

The BabyBuddha breast pump has an extra-soft cushion to prevent nipple soreness but most moms mentioned that the long pull on this system is really so painful.

Some moms even said some blood came out while using the Baby Buddha and some wanted to cry out from the pain!

Even the lowest of settings can be quite intense for pumping but one mom recommended switching first to let down mode 1 or 2. This can give you a letdown without the very uncomfortable long pull.

Other moms mentioned that it’s not as gentle but you’ll eventually get used to the suction power of the Baby Buddha.

Saved Settings 

Spectra S9 can’t save the last pumping mode setting you used as it always reset every time you turn it off.

This can be a hassle, especially if you’re a sleep-deprived, overwhelmed mom with a clingy newborn.

So you must remember or at least write down the most efficient mode for you, so there will be less wasted time adjusting it when pumping.

Baby Buddha saves the last setting but remembers to always adjust it to the lowest mode or to the most comfortable one BEFORE pumping. Since its suction can be quite powerful and painful.

Hospital Grade

The Baby Buddha is considered a hospital-grade breast pump. 

The Spectra S9 is not. It has a less powerful motor and is only for personal use. Which means you can’t share it nor resell it.

Similarities of BabyBuddha vs Spectra S9 Plus

Now let’s take a more detailed look at the similar features of the Spectra S9 vs S2.

Closed System 

Both the Spectra S9 Plus vs Baby Buddha are closed system breast pumps, with Spectra’s backflow protector and Baby Buddha’s anti-backflow design.

This means, milk cannot go up the tube and into the motor, which can cause mold or can contaminate your milk.


Both the Spectra S9 vs Baby Buddha is BPA-free, meaning there’s no toxic ingredient in their parts that can harm and induce negative health effects.

Universal Voltage

Both the Baby Buddha vs Spectra S9 Plus can be used in another country, with the use of a travel adapter.

The Spectra S9 has an input: 100V-240V / 50-60Hz while the Baby Buddha can handle 120v-240v.

Adjustable Pumping Mode 

Both the Spectra S9 and Baby Buddha have 2 pumpings modes with varying adjustment levels.

The 2 pumping modes are the following:

  • Massage mode – stimulates letdown (mimics suckling baby)
  • Expression mode – to be used after letdown

The Spectra S9’s massage mode can be adjusted from level 1 to 5. Its expression mode can be adjusted until level 10. 

It doesn’t have any suction speed control though but you can easily switch modes and switch your settings on the Spectra S9 Plus.

The Baby Buddha’s massage mode can be adjusted up to level 5 and has a range of 60mmHg – 112.5mmHg.

Its expression mode can be adjusted up to level 9, with a suction range of 67.5mmHg – 307.5mmHg. Its maximum is stronger than a Spectra!

This is the strongest feature of the Baby Buddha – its powerful suction, which can give you better output at a shorter time!

However, it can take some time to get used to it, as most moms mention that the suction can be quite painful. 

So always make sure to set it at the lowest level letdown or massage mode BEFORE using it. It will increase the level every 45 seconds until it reaches level 5 or the maximum stimulation mode. Yikes!

But if you manually change the level, the automatic stimulation mode will turn off.

Some moms wish the Baby Buddha has a lock setting, as the trackball can be quite sensitive. It can bump your mode into a higher setting while you’re moving around. So be very careful, unless you want to get a painful tugging surprise!

Turns into Single and Double Pump

Both the Baby Buddha and Spectra S9 Plus can be used as a double or single pump.


Both the Spectra S9 Plus and Baby Buddha are small and portable breast pumps, which are very convenient to bring to work, travel, or vacations.

The Spectra S9 Plus weighs .5lbs or 0.23kg while the BabyBuddha is lighter and more compact, weighing only 0.04 kg, and is even smaller than an iPhone!

You can even hang the Baby Buddha around your neck and keep your hands free to do work, clean the house, do chores or take care of your baby.


Both the Baby Buddha vs Spectra S9 comes with their own complete set of accessories. 

The Spectra S9 Plus breast pump includes:

  • (1) detachable power cord prongs 
  • (2) Spectra bottles
  • (2) Spectra backflow protector
  • (2) Spectra duckbill valve
  • (2) Spectra tubing
  • (2) Spectra flange 24mm

I highly recommend checking out Spectra’s flanges fitting guide here, so you can buy it together with the whole breast pump set.

Get also a carrying case, as it doesn’t come with the kit. One with an insulated cooler to store the bottles and ice packs is better to have.

Make sure to check when to replace Spectra parts below:

  • Valve Membrane: Replace every 2 – 8 weeks, or when you notice a decrease in suction.
  • Duck Valve: Replace every 2 – 3 months, or when you notice a decrease in suction.
  • Backflow Protector: Replace every 3 – 6 months.
  • Breast Flange: Replace every 6 months.
  • Tubing: Replace should moisture ever enter the tubing.

Some moms have managed to use other brands with the Spectra, such as:

Just take note that it might void your warranty if there are issues or malfunction which you can get from using other brands.

Now let’s take a look at the Baby Buddha breast pump kit. It includes:

  • (2) Sets of Duckbill Valves
  • (1) Pair of Silicon Diaphragms
  • (2) Bottles
  • (2) Bottle Bases
  • (2) Bottle Storage Caps
  • (2) Bottle Hygiene Covers
  • (2) Pump Covers
  • Three detachable tubes (for easy cleaning) & T-connector.
  • USB Charging Cable (charge to full in 4 hours)

Remember to also get the right flange size for your Baby Buddha, together with the whole set. You can check out their fitting guide here.

You can also use other brands with the Baby Buddha. The company even shared the accessory hacks on their website!

Take note of when to replace Baby Buddha parts below:

  • The silicone diaphragms should be replaced every 8 weeks
  • The duckbills should be replaced every 4 weeks
  • Tubing should be replaced every 6-12 months depending on condition.


Some moms said that the Spectra S9 is relatively quiet while other moms mentioned that it’s too loud for them.

Baby Buddha has also the same mixed feedbacks, with some saying it’s very quiet while others say they’re not comfortable pumping at work because of the noise it makes.


It’s mixed feedback again for both the Baby Buddha vs Spectra S9 when it comes to washing and cleaning it.

Some moms said that the Spectra S9 is so much easier to clean while others are saying it’s quite difficult, as the flange piece does not come apart easily.

Other moms find the Baby Buddha easy to clean but some moms find it a hassle because it has a lot of parts, so cleaning takes longer.


Both the Spectra S9 vs Baby Buddha has a backlit display, a feature that’s useful to pump in the dark.
