Robot vacuums have steadily evolved from simple floor sweepers into intelligent cleaning systems capable of handling increasingly demanding household messes. Ironically, even premium models continue to struggle with one persistent challenge, which is dried-on stains that require manual scrubbing after the cleaning cycle is complete. Yeedi aims to plug this gap with S20 Infinity Ultra, a flagship robot vacuum and mop designed around a new stain pre-treatment system called FocusJet Technology.
Unlike conventional robot mops that rely mainly on repeated passes and increased downward pressure, the S20 Infinity Ultra approaches stubborn stains differently. The proprietary FocusJet Pre-Treatment Technology sprays a diluted cleaning solution directly onto dried spills before the mop roller reaches the surface. Using dual high-pressure atomizing nozzles, the system is designed to loosen hardened residue in advance, helping the vacuum tackle sticky kitchen spills and tracked-in dirt more effectively in a single cleaning pass.
The idea behind the system is straightforward; instead of forcing the mop to scrub harder, the robot softens the mess first. This approach targets one of the biggest frustrations with automated floor cleaning, especially in busy households where stains can sit for hours before being cleaned. The technology recently earned the Digital Trends Digital Spotlight Award, highlighting the company’s effort to rethink how robot mops handle deep-cleaning tasks.
The S20 Infinity Ultra also introduces an upgraded OZMO Roller 3.0 system featuring a 27-inch-wide roller mop. The wider roller improves floor coverage while continuously self-washing during operation to help reduce residue buildup and maintain consistent cleaning performance throughout the cleaning session. This self-cleaning design is particularly useful for larger homes where dirt accumulation on the mop can reduce effectiveness over time.
Vacuuming performance is equally aggressive as the robot delivers up to 22,000Pa suction power – handling dust, pet hair, debris, and embedded particles across both hard floors and carpets. To improve whole-home usability, the model includes automatic mop lifting alongside a Mop Roller Smart Cover system that helps prevent wet carpet contamination during mixed-surface cleaning.
Navigation and obstacle handling are managed through AIVI 3D 4.0 intelligent navigation, which allows the robot to map rooms and maneuver around common household obstacles more accurately. Yeedi also includes its ZeroTangle 4.0 technology to reduce hair wrapping around the brush assembly, a feature that can significantly cut down maintenance for homes with pets or long hair.
Edge cleaning remains another common weak point for robot vacuums, particularly around furniture legs and wall corners. The S20 Infinity Ultra addresses this with TrueEdge 3.0 technology designed to improve cleaning precision along edges and hard-to-reach spaces. Meanwhile, PowerBoost Charging Plus restores up to 13 percent battery capacity in just three minutes, reducing downtime between cleaning cycles.
Yeedi S20 Infinity Ultra is now available through Yeedi’s official store and Amazon. The robotic vacuum cleaner is currently up for a promotional price of $899.99 through June 10, after which it will retail for $999.99. Early buyers will also receive complimentary cleaning solution bottles and additional side brushes while supplies last.
Alongside this, Yeedi is expanding its direct-to-consumer strategy through the debut of its new official online store, giving customers access to accessories, replacement components, promotions, and future product releases directly from the company.
