βοΈ External Motor vs. Wearable Pumps: What You Need to Know
Hereβs something important:
π¬ Pumps with external motors will always be more powerful than hands-free models β and this applies to all brands, not just Primo Passi.
Why? External motors are:
-
Physically larger and more stable
-
Capable of delivering higher, more consistent suction
-
Designed for long-term and frequent use
Wearable pumps are more compact and portable β perfect for flexibility and discretion, but with slightly less suction due to space limitations.
β¨ Itβs all about what matters most to you:
Choose a pump with an external motor if you want:
βοΈ Strongest suction
βοΈ Greater control over modes and power
βοΈ Better performance for regular pumping
Choose a wearable pump if you want:
βοΈ Hands-free comfort
βοΈ Discretion and mobility
βοΈ Lightweight, on-the-go use
Thereβs no one-size-fits-all solution β just the right pump for your routine.
