This model operates more quietly than most, excelling in both vacuuming and mopping while taking care of much of your home's deep cleaning.
Its ability to use cleaning solution is a standout feature; after all, mopping with just water isn't effective. The Yeedi S20 Infinity [at Amazon] is Matter-certified, allowing it to connect seamlessly with any smart home system. Here's why I rate it highly.

Setup Process

Unboxing was easy, with minimal plastic waste.
Unboxing the Yeedi S20 Infinity was surprisingly simple. The side brush was already attached, requiring only minimal unpacking. However, the base station was heavier and required more effort to set up, including installing a base plate.
Though the protective plastic ensured safety during transport, it made unboxing a bit tedious. Overall, unboxing took about five minutes.

The app simplifies feature usage.
Setting up is straightforward. After powering the base station and vacuum, follow the app prompts to connect it to your WiFi. Note that it requires a smartphone for full setup.
Before running, fill the clean water tank and the cleaning solution reservoirs if chosen as extras.
Design and Features of the Yeedi S20 Infinity

Extendable brushes enhance edge cleaning.
The Yeedi S20 Infinity maintains the sleek design of its predecessors, featuring a stylish black and gray exterior with hints of red. Its flat top helps it fit under furniture, hiding the power slider, pairing button, and dustbin behind a removable faceplate.
It includes a compact water reservoir and a unique anti-tangle brushroll that effectively tackles pet hair. The single side brush is angled to push debris forward rather than aside.
The innovative Ozmo Roller 2.0 mopping brushroll extends out to reach edges and operates in a back-and-forth motion, effectively cleaning spills without re-distributing messes.
Control the Yeedi S20 Infinity via the app, which allows for detailed adjustments, including scheduling and voice settings. Its compatibility with Matter means it integrates seamlessly with various smart home systems.
The base station offers significant design improvements, holding multiple cleaning solutions for various spills, while regularly washing and drying the mop. Cleaning solutions must be purchased separately, but the dustbin is a reusable canister, minimizing waste.
However, the water tanks are on the smaller side. The vacuum often washes its mop, necessitating regular filling of the clean water tank and emptying of the dirty one.
User Experience with the Yeedi S20 Infinity
Using the Yeedi S20 Infinity is comparable to other recent robot vacuums. While it has a manual start button, I found the app to be my go-to for scheduling and settings.
Adjusting cleaning parameters is straightforward through a menu, offering flexibility in vacuuming and mopping strengths. The AI mode adapts settings automatically, enhancing user-friendliness.
While I don't recommend relying solely on robot vacuums for deep cleaning, the Yeedi S20 Infinity excels at daily maintenance, efficiently picking up dust, pet dander, and crumbs.
Its quiet operation impressed me further. It runs at approximately 56 dB, quieter than many competitors, although the self-emptying feature can be louder at 76 dB, but only briefly.
The object avoidance system effectively navigates around obstacles, and you can adjust the app settings for wider avoidance, ensuring it doesn't bump into pets.
With a six-inch cleaning path, it mops evenly without leaving streaks. It automatically lifts the roller when moving to carpeted areas, preventing wet carpets.
During testing, the battery life lasted over 254 minutes, and it recharges swiftly, gaining 6% in just three minutes.

Vacuuming Performance
I tested the Yeedi S20 Infinity on hardwood and low-pile carpets using flour, sugar, lentils, and cereal to examine its performance with various debris. While it excelled at picking up dust and pet hair, these controlled tests revealed some limitations.
With 19,500Pa suction power, it effectively captures debris. It performed admirably on both hard and carpeted surfaces, particularly with lentils and cereal, outdoing the Yeedi S14 Plus.
It effectively cleaned edges on hardwood but had some challenges on carpets near molding, which is not unusual for robot vacuums.
Despite its strength, nothing beats manual deep cleaning for stubborn messes. While it struggled with small particles like sugar and flour on hard surfaces, it performed better on carpet, requiring multiple passes on tougher debris.
Mopping Performance
The Yeedi S20 Infinity excels in mopping, outperforming many other models by using a cleaning solution. It's one of the few that offers this feature, alongside the eufy Omni S1 Pro.
The Ozmo Roller 2.0 brushroll mimics traditional mop behavior, providing an effective cleaning surface while utilizing the spinning pressure of round mop pads.
It swiftly tackled mustard and ketchup spills in one pass, though it does struggle with large liquid amounts. It left some lines of residue but overall cleaned the floor well.

Maintenance Insights

The mop roller isn't removable, raising long-term cleaning concerns.
Understanding maintenance is crucial for the robot vacuum's longevity. The brushroll and its housing are easy to remove for cleaning, while the filter behind the mopping brushroll is easily accessible.
However, other components are less accessible, particularly the mopping brush, which may require cleaning after heavy use. Routine maintenance is straightforward, as the base station automatically empties the vacuum's contents upon docking, needing monthly emptying.
The base uses a reusable canister, reducing waste, but the water tanks are smaller than average, requiring frequent refills and emptying due to the mop washing feature.
Comparative Overview
With an MSRP of $1,599.99 at Amazon, the Yeedi S20 Infinity is a premium model, packed with features like high suction and smart home compatibility. Often discounted, it can be found at a lower price.
In comparison, the Yeedi S14 Plus, with an MSRP of $1,199.99, frequently drops to $549.99, providing a solid alternative without smart home support or cleaning solution usage.
The Eufy Omni S1 Pro, priced similarly to the S20 Infinity but often discounted to around $900, also uses cleaning fluid but lacks the suction power of Yeedi's models.
Testing Methodology
Testing the Yeedi S20 Infinity involved extensive use over a week in a busy household with multiple pets. I ran daily vacuum and mop cycles, adjusting settings as needed.
For specific tests, I examined its performance with sugar, lentils, and cereal on both hard surfaces and carpet, also conducting mopping tests with ketchup and mustard.
