You're standing in an aisle (or scrolling online) staring at two robot vacuums that both promise to change your life, and they're priced closer than you'd expect. The Yeedi S20 Infinity Ultra is the newer kid on the block—sleek, feature-packed, and often $200–$300 cheaper. The Roborock Qrevo Curv is the established name, backed by years of customer reviews and a reputation for just... working. So which one actually deserves a spot in your home?
The Yeedi S20 Infinity Ultra is for budget-conscious people who like cutting-edge tech and don't mind being early adopters. The Roborock Qrevo Curv is for folks who'd rather pay a little more for proven reliability and the peace of mind that comes with a brand that's been perfecting robot vacuums for over a decade.
In this post, we'll break down cleaning power, navigation smarts, mopping ability, noise levels, app experience, and real-world value so you can make a decision that actually fits your home and your gut feeling.
Yeedi is a newer Chinese robotics company that burst onto the Western market with aggressive pricing and impressive specs—think of them as the Tesla of vacuum brands. Roborock, also Chinese but with a longer track record, has become almost synonymous with robot vacuums for millions of households worldwide. Both the S20 Infinity Ultra ($599–$699) and Qrevo Curv ($799–$899) are premium models with mopping, advanced navigation, and app control. Yeedi is famous for packing features into lower price tags; Roborock is famous for making vacuums that just don't fail.
Cleaning Power: Who Wins at Actually Picking Up Dirt?
Both vacuums use suction power measured in Pascals (basically a unit that tells you how hard the vacuum sucks), and both are rated around 10,000 Pa—think of it as
Navigation: Finding Your Way Through the Maze Without Getting Lost
The S20 Infinity Ultra uses LiDAR (a spinning laser on top that reads your room like a bat reads a cave with sound waves) and has been refined quickly. The Qrevo Curv also uses LiDAR but adds Roborock's years of software tweaks, so it navigates like it's walked your home a hundred times already. In real terms: both will map your rooms cleanly, but the Roborock feels slightly more confident on the first run.
Mopping: Wet Floors and Peace of Mind
Both vacuums mop and dry their mop pads with hot water (the S20 heats water to about 55°C, the Qrevo to similar temps). The S20 is newer and shows off this feature more aggressively in marketing. The Qrevo has more proven track records from people who've been using it for a year or more, meaning fewer surprises. If you have a small kid and want zero risk of puddles, the Qrevo's caution might feel safer.
Noise Level: Can You Watch TV While It Works?
The S20 Infinity Ultra runs at roughly 67–69 dB, while the Qrevo Curv sits around 65–67 dB—both are about as loud as a busy office or a vacuum you could half-yell over. The difference is honestly too small to matter for most people. If silence is your dream, neither is the answer, but both are acceptable for daytime use.
App and Smart Features: Which Doesn't Make You Want to Throw Your Phone?
The Yeedi app is newer and feels slick—it's like someone designed it last year instead of three years ago. The Roborock app has more bells and whistles and years of user feedback baked in, so it rarely surprises you badly. Yeedi's app might crash occasionally as they push updates; Roborock's won't crash but might feel slightly dated. For a beginner, the Roborock app's stability probably matters more than Yeedi's design.
Value and the Elephant in the Room: Is Cheaper Always Better?
The S20 Infinity Ultra undercuts the Qrevo Curv by $150–$200, which is real money—that's a nice dinner or a month of streaming services. But 'cheaper' often means 'fewer people have owned it long enough to report year-two problems.' Roborock's premium partly pays for customer service that actually picks up and a parts ecosystem so mature you can find a replacement brush at 11 p.m. on a Sunday. Yeedi is getting there, but they're not quite there yet.
So, which one should you buy?
Here's the honest truth: both of these robots will clean your floors better than you ever did manually. The Yeedi S20 Infinity Ultra is genuinely impressive for the price and works hard to prove it has nothing to apologize for. The Roborock Qrevo Curv costs more because you're buying peace of mind, established support, and the comfort of knowing thousands of real humans have already lived with this thing for 18+ months without major regrets. Neither is a bad choice; you're really choosing between 'new and thrifty' and 'proven and reassuring.'
So here's the nudge: if you're the type who loves being an early adopter and doesn't mind researching solutions online, grab the Yeedi. If you'd rather have one less thing to worry about and sleep easily knowing that customer service exists, the Roborock is your friend. Either way, you're getting a genuinely smart robot vacuum, not a gadget that'll collect dust in your closet.
