Baby Bottle Washers Review: Baby Brezza and Momcozy

After welcoming my first baby, washing bottles became a point of contention in my marriage. I preferred to toss them into the dishwasher (highly recommend this basket for holding nipples and other feeding accessories) but often forgot to run it. My partner preferred to wash them by hand but rarely had the time. It felt like there was never a clean bottle when we needed one, and we weren’t very, ahem, kind to each other about it. Fast forward to having our second baby in 2024, and baby bottle washing machines were finally a thing. Spoiler: they‘re so life-changing that we put one on Babylist’s list of the year’s best new products. And I tested two of them.

The first one I tested, the Momcozy Kleanpal Pro, instantly restored my marriage to a happy union. We became so obsessed with (and dependent upon) it that we got greedy—and wondered whether there was another bottle washer out there that could make us even happier. So I brought home the Baby Brezza Bottle Washer Pro, set it up next to the Momcozy and took notes for over a month. I tracked everything from machine cycle time and bottle cleanliness to ease of use and noise levels. 

In short, they’re pretty comparable and both amazing. But the little details will make one better for you, depending on your family’s lifestyle and needs. (The Momcozy has all the features my partner and I love, while the Baby Brezza is my friend’s favorite thing ever, because of her family’s needs.) Here’s what I learned while reviewing them side by side.

Functionality: Which baby bottle washer works better?

Both the Baby Brezza and Momcozy wash, dry and sterilize—in a little over an hour and a half total. When I timed them, the Baby Brezza was slightly faster (1 hour, 35 minutes) than the Momcozy (1 hour, 45 minutes).  

They’re both equipped with pause buttons, so you can easily add or remove items once the machines have been powered on. (A handy feature when you stumble upon a rogue pacifier on the floor, etc.)

And the Momcozy has a rapid cycle wash option (19 minutes), which we often use in the morning, when we need to clean the overnight bottles before packing up milk for daycare.

In terms of which is more effective, both products clean very well. I rinsed breastmilk off all bottle parts (including nipples), pump parts and pacifiers before loading them into both machines—and everything came out spotless, every time. 

The Momcozy completely dries the bottles, too. In the Baby Brezza, though, I often found water sitting atop the bottoms of the bottles after a cycle was over (like you would in a dishwasher).

Load capacity: How much can I fit in the baby bottle washers?

The Baby Brezza and Momcozy both have two-tier designs that can hold up to four bottles on one level and accessories on another level. 

The Baby Brezza has a designated area for tall bottle parts, like those inside Dr. Brown’s bottles. It’s a thoughtful design, but we found that the bottles themselves would sometimes topple out of the Baby Brezza while loading it.

The Momcozy held our bottles (Pigeon) in place more securely; my Spectra pump parts also fit better in the Momcozy.

Water usage: How much water does it take to run bottle washers?

The Baby Brezza and Momcozy models both use less than a gallon of water to wash, dry and sterilize each load. For context, standard dishwashers use about 4 to 6 gallons per cycle. If you’re interested in conserving as much water as possible, opt for the Momcozy, which requires just 2.5L (compared to Baby Brezza’s 3L).

It’s worth noting that both brands recommend using purified or distilled water in order to avoid mineral residue, particularly if you have hard water or well water. For testing purposes, I used tap water (from a well) for over a month and had no problems.

Size: How much counter space do I need?

Both bottle washers are similar in width, but the Baby Brezza is considerably longer from front to back, and the Momcozy is a bit taller. After measuring your space, you’ll want to make sure you have room for these dimensions: the Baby Brezza is 18”D x 9”W x 15”H, while the Momcozy is 13”D x 10”W x 16.5”H.

The Baby Brezza has wheels on the bottom, so you can easily slide it towards the sink (a handy feature when filling the clean water tank or dumping the dirty water tank) and then back to a power outlet (to plug it in and turn it on). Even if you don’t want to slide it across the counter, you will need to access the back of the unit in order to remove the dirty water tank from the bottom, so you will want to have enough room to at least spin the machine around.

The Momcozy only has one water tank (for clean water), which can easily be removed without moving the machine. But in order to operate, the unit itself needs to be positioned in a place that can reach both a power outlet and the sink (or a bucket) at the same time: instead of draining dirty water into a tank (like the Baby Brezza), the Momcozy is equipped with a drain pipe that runs out of the back of the machine.

Price: How much does each bottle washer cost?

Both units cost the same amount: $299.99. It’s a lofty expense, which was easy for us to justify since we go through so many bottles each day and completely loathe washing them by hand. (P.S. This would make a great registry group gift!) 

Both brands also require brand-specific detergent tablets (as opposed to using standard dish detergent). The tablets are significantly smaller in size than what you would put in a regular dishwasher—and both brands’ are billed as fragrance-free, non-toxic and hypo-allergenic. The baby bottle washer machines come with 60 tablets each, and the refills also cost the same amount: $19.99 for 120 tablets from both Momcozy and Baby Brezza.

FYI: For testing purposes, I tried using the Momcozy tablets in the Baby Brezza machine and vice versa, and I experienced no issues.

Noise: Which baby bottle washer is louder?

While both machines put out a certain level of white noise, the Baby Brezza is noticeably louder. 

When our baby was placed in a bassinet close to the kitchen, he tended to sleep through the Momcozy cycle, which sounds like his favorite white noise machine, but would startle a bit when the Baby Brezza was running.

Final Thoughts

We continue to love using our Momcozy and can’t recommend it enough as a nice-to-have item. But if you wouldn’t be able to reach the sink with the Momcozy’s drain pipe while the machine is plugged into a power outlet, you should opt for the Baby Brezza—which is a great option, too!

If you’re reading this as a gift giver, a baby bottle washer would make a fantastic gift for any family—particularly single parents or households where one parent is often away (traveling or at an office). It’s like having an extra set of hands around the house, aka more free time for taking a shower or enjoying a nap or marveling at a tiny human while…feeding him a bottle.
