Surprising Benefits of a Dual Motor Breast Pump (Like the Cimilre S7 Dual Pro)

June 11, 2025
Share

Chances are you’ve heard about dual motor breast pumps – but what does that actually mean for you? Let’s break it down.

What is the difference between double electric and dual motor breast pump?

When you hear double electric being used for most breast pumps, you may be wondering what the difference between double electric and dual motor is. Double electric means you can pump from both sides at the same time with an electric breast pump. Any pump that allows you to pump both sides at the same time is considered double electric. Most double electric breast pumps have one single motor, which require both sides to operate at the same speed and suction level.

Enter – the dual motor breast pump. With two motors, you can control the suction for each side independently or use one setting for one side and another setting for the other side. This gives you flexibility to fine tune pump sessions to what your body needs to optimize output without sacrificing comfort.

Benefits of a Dual Motor Breast Pump

Whether you’re dealing with a slacker boob or just want a breast pump with independent suction control, a dual motor breast pump like the S7 Dual Pro Rechargeable gives you a finer level of control, which, in turn, gives you a few (surprising) extra benefits:


Independent control over each side


Every boob is different. With a dual motor breast pump, you can control the settings on each side based on what feels right. Whether one side is more sensitive than the other or one side needs a little more oomph, a dual motor breast pump lets you tailor pump sessions for each side.


Focus on slacker boob


Having one side produce more milk than the other is completely normal. In fact, studies show that as many as 90% of lactating parents produce more on one side. That said, some breast pumps are better for uneven milk supply than others. With a dual motor breast pump, you can optimize sessions to get the most out of both sides. Even if you label one side a slacker boob.


Adjust settings along your journey


Babies, bodies, and boobs change throughout your journey. It’s helpful if your pump can too! With a dual motor breast pump, you can adjust settings through your breastfeeding journey.

Stronger double pumping suction

Most single motor breast pumps lose suction when double pumping. With a dual motor breast pump, the suction remains the same whether you are double pumping or single pumping. Because two separate motors are used, you can even leave both tubes plugged in whether you are single or double pumping.

S7 Dual Pro Rechargeable Bonuses

The S7 Dual Pro Rechargeable gives you dual motors to independently control each side. It also gives you a few more award-winning bonuses:

  • SYNC Mode – If the thought of having two different motors gives you a little sensory overload – fear not! We get it. Not everyone wants motors that are, well, out of sync. That’s why the S7 Dual Pro Rechargeable has SYNC mode, so each motor can work together simultaneously or independently, whichever your preference.
  • Adjustable cycle speeds. Three cycle speeds per level to be exact! Having adjustable breast pump settings, more specifically adjustable cycle speeds, or how fast the nipple is being pulled into the tunnel, can make all the difference. Not just in comfort, what feels better for you, but also in how it works. It allows you to make your pumping experience get closer to the way your baby feeds from your chest. Comfort meets efficiency.
  • Super cute and functional. With a sleek, ergonomic handle that doubles as a night light, and light weight design, the S7 Dual Pro is perfect for late night and early morning pump sessions, or to take with you wherever you go. It even looks like a cute purse!
  • Complete with Cimilre’s resources. We are on a mission to get your journey off to the right start. That includes making sure you have the right size breast shield. Breast shield size is crucial to pumping success! Use our Breast Shield Sizing Guide with printable ruler to measure. If you feel like you need a little help measuring, we got you with our Virtual Sizing Consults with a CLC. You can even Get the Right Fit with a 3rd set of breast shields free if the sizes in the box don’t fit.
