CNN Underscored is constantly testing products—be it flashlights, photo printers, or food dehydrators—to find the absolute best in each individual category. Our testing process is rigorous, starting with spending hours researching to find the best products in each category. Once we create a test suite of products, we test and re-test each product multiple times in real-world settings over the course of several weeks or even months.
This year we’ve already tested several hundred products – from PS5 games to smartphone apps to wireless speakers – to find the best products you need to improve your life. Here are the winning products from March.
Best robot mop overall
Compact and inexpensive, the iRobot Braava Jet 240 is simply the best robotic mop for the money. While it doesn’t have the smarts of more expensive models and can’t do double duty as a vacuum cleaner, its efficient design and simple, pattern-based navigation system delivers a great clean.

A good choice for music lovers
If you’re willing to splurge on a stylish pair of headphones with true audio-grade sound (and can live without features like active noise cancellation), the Master & Dynamic MH40 are well worth the investment.

Excellent little wireless speaker
The Era 100 produces more sound than the Sonos One without increasing the volume too much and delivers impressive sound for a small speaker. Adds Bluetooth and the option of external sources through a line adapter. But the price went up again.

Room-filling sound from a single speaker
The Era 300 makes it easy to enjoy immersive spatial sound; With spacious sound, you’ll feel like you’re listening to more than one speaker. With its clean bass and deep bass, it sounds good with regular stereo music, too. It’s packed with features, but you pay a premium for the privilege.

A unique rowing experience with a clean and intuitive interface
The Hydrow Rower is a stylish premium rowing machine that pairs itself with a $44 per month All-Access membership. Yes, it provides a full-body cardio and kicking workout, but we loved how rowing gets back to its roots with live lessons filmed in real places. It may be pricey, but if you want to feel like you’re rowing on water, this home gym rowing machine is for you.

A classic trail runner with better traction
Fans of the Lone Peak series will love the new seven models for their wide width and improved grip, while newcomers to this shoe may be surprised by its lack of cushioning and no-drop design. Either way, the Altra manages to deliver another great sneaker, with no-slip laces and just the right amount of breathable mesh.

A near perfect bottle with a few imperfections
It’s not perfect, but the HydraPak Flux+ 1.5L Collapsible Bottle has an impressive flow rate and rugged exterior, making it the best dog on the bottle market with built-in filters. The difficulty of keeping it clean, especially in the long term, prevents it from being an ideal choice.

A helpful sleep aid that focuses on calm breathing
Dodow sleep aid is a unique and useful device. It helped us fall asleep faster and more consistently. It’s not hard to learn to sync your breath with the light, and once you get used to the process, you’ll feel the results. Just inhale when it expands and out when it contracts.

Attractive multitasking bedside helper
Hatch Restore 2 is a comprehensive sleep machine that uses light and sound to help you fall asleep faster and stay asleep longer. The companion app gives you access to a library full of colored lights, white noise, sleep stories, and guided meditation. But where the Restore 2 really shines is its awesome sunrise alarm, which wakes you up gently and more humanly than your average alarm clock.

Countertop oven suitable for busy cooks
The Tovala Smart Oven Air Fryer delivers simple, freshly prepared meals for one person, Wi-Fi connected, and one-touch cooking. A great budget toaster oven if you order meals, it jumps to a higher-priced, less useful buy if you’re more interested in cooking from scratch. However, if you’re looking to save time and energy, this countertop oven beats frozen and supermarket foods.
