Willow Go vs. Willow Wave: Which Wearable Pump Fits Your Lifestyle?

Quick answer

Choose the Willow Go if you want an electric, hands-free pump with hospital-grade suction for regular, full-volume pumping sessions. Choose the Willow Wave if you prioritize ultimate portability, discretion, and simplicity for occasional or on-the-go relief. The Wave requires no charging and is completely in-bra, making it a practical backup or travel companion.

Deciding between the Willow Go and the Willow Wave comes down to how you plan to pump. Both are wearable and fit inside your bra, but they serve different roles. The Willow Go is a full-featured electric pump designed for daily, efficient pumping. The Willow Wave is a manual pump built for flexibility and travel, with no cords, tubes, or batteries.

In this comparison, we'll break down the key differences—from suction power to portability—so you can pick the pump that matches your lifestyle. We'll also share tips for getting the most out of each, including how to clean and travel with them.

Electric vs. manual: How they differ

The most significant difference is power source. The Willow Go is an electric wearable pump with hospital-grade suction, designed for efficient, hands-free pumping. It connects to the Willow app, letting you track sessions and control settings. The Willow Wave is a manual pump that relies on your own hand pressure—no charging, no app, no cords.

This makes the Wave incredibly portable and discreet. It fits completely in-bra, so you can pump while walking, working, or traveling without needing an outlet or a private space. The Go, while also wearable, requires charging and is better suited for longer, more established pumping sessions.

• If you pump multiple times a day, the Go's electric suction saves time and effort.
• For occasional relief or travel emergencies, the Wave's simplicity is a huge advantage.

Comfort and milk flow

Both pumps prioritize comfort, but in different ways. The Willow Wave features a 24mm flange made of soft silicone, designed for a smooth fit and optimal milk flow. Its 5 oz capacity with a splashguard and easy-pour spout helps prevent spills. The Willow Go is engineered for comfort and efficiency, with customizable tubing that tucks neatly into your bra for discretion.

The Go's hospital-grade suction can be adjusted to your comfort level, which is helpful for moms who need a stronger pull. The Wave's manual control lets you set the rhythm and pressure yourself, which some moms find more natural. Neither is inherently better—it's about what feels right for you.

• Consider your nipple sensitivity and preferred suction strength when choosing.
• The Wave's soft silicone flange may be gentler for tender breasts.

Portability and travel

When you're on the go, the Willow Wave shines. It's compact, requires no charging, and is completely in-bra—no air horns or tubes to manage. You can toss it in a diaper bag or purse and be ready for a quick pump anywhere. The Willow Go, while wearable, needs to be charged and is slightly bulkier due to its motor.

For travel, the Pump Anywhere Bag is a great companion for either pump. It holds your pump and keeps milk cold with a removable cooler, and it can be worn as a backpack, crossbody, or shoulder bag. This versatility makes it easy to carry your pump and supplies to work, on a flight, or on a road trip.

• Pair the Wave with the Pump Anywhere Bag for a lightweight travel setup.
• If you're flying, the Wave's lack of batteries means no charging worries.

Cleaning and maintenance

Both pumps require regular cleaning to maintain hygiene and performance. The Willow Go is top-rack dishwasher safe, making cleanup easier. The Willow Wave's silicone parts are also easy to rinse and air dry. For thorough cleaning, the Dapple Baby Pump Cleaning Kit is designed specifically for Willow pumps, using plant-based ingredients to remove tough milk residue.

Proper cleaning extends the life of your pump and ensures milk safety. Replace parts as needed, especially valves and flanges, to keep suction optimal. Always follow the manufacturer's instructions for cleaning and sanitizing.

• Use the Dapple kit for a deep clean on the go or at home.
• Check parts regularly for wear and replace them to maintain performance.

Trade-offs at a glance

• Suction power: The Willow Go offers hospital-grade suction, which is more efficient for full milk removal. The Wave relies on manual pressure, which may be less consistent but gives you full control. If you have low milk supply or need efficient pumping, the Go is the better choice.
• Portability: The Wave is ultra-compact, requires no charging, and is completely in-bra. The Go is wearable but needs to be charged and is slightly bulkier. For travel or occasional use, the Wave wins on convenience.
• Cost and simplicity: The Wave is a manual pump, so it's generally more affordable and has fewer parts to maintain. The Go is an electric pump with more features and a higher price point. If budget is a concern or you prefer a low-tech option, the Wave is a smart pick.
