Prime Day ended and the Roborock Saros 10R got cheaper, not more expensive. Cheaper. Amazon has it at $899, a further reduction from its Prime Day price and $700 off its $1,599 standard price, for a 3.14-inch ultra-slim robot vacuum and mop with 22,000Pa suction, StarSight Autonomous System 2.0, FlexiArm corner cleaning, 60-day hands-free operation, 176°F hot water mop washing, and a built-in RGB camera for pet monitoring. Prime membership still needed.
3.14 inches thin, under every sofa that previously won
Standard robot vacuums sit between 3.5 and 4 inches tall because the LiDAR tower that handles navigation protrudes above the body. The Roborock Saros 10R eliminates that tower entirely with StarSight Autonomous System 2.0, which integrates all navigation sensors into the flat 3.14-inch profile using structured light, a 100-degree Vision Module, and VertiBeam Lateral Obstacle Avoidance. The result is a robot that slides under beds, sofas, coffee tables, and cabinets that have been accumulating dust undisturbed for as long as the current robot vacuum has been leaving them alone. If there’s a piece of furniture in your home with a gap between 3.14 and 3.5 inches, every other robot vacuum has been ignoring everything under it. This one hasn’t.
The FlexiArm Riser Side Brush extends beyond the robot’s body to reach corners and wall edges, sweeping dust from spots that the fixed side brushes on standard robots physically can’t access. The Zero-Tangling DuoDivide Main Brush handles pet hair and long hair without the wrap that stops cheaper robots mid-session, and the anti-tangle omnidirectional wheels eliminate the other tangling point that most robot vacuum maintenance involves. The AdaptiLift Chassis navigates obstacles up to 4cm high including thresholds and U-shaped furniture legs, and the Dual Spinning Mops lift automatically when carpet is detected to keep rugs dry without mode switching.
The 10-in-one Dock 4.0 handles auto mop removal, 176°F hot water mop washing, 131°F hot air drying, 60-day automatic dust collection, auto water tank refilling, and auto detergent dispensing without requiring any input between cleaning sessions. When heavily soiled areas are detected, the dock activates auto re-wash and re-mop cycles for those specific zones rather than applying uniform cleaning intensity regardless of what the floor actually needs. The built-in RGB camera enables two-way video calls and one-click pet search from the Roborock app, and the Hello Rocky voice assistant handles cleaning commands without a phone or internet connection.
$700 off and still getting cheaper the day after Prime Day
The Roborock Saros 10R launched at $1,599 and has never been close to $899 before this week. The further price reduction the day after Prime Day ended is the specific detail that makes checking today more interesting than it was yesterday: Amazon didn’t reset to standard pricing when Prime Day closed, it went the other direction. Whether that reflects a deliberate extended promotion, inventory pressure, or a pricing decision made without announcing it publicly, the number is real and the deal is the deepest this product has ever reached.
At 22,000Pa of suction, 3.14-inch clearance, corner cleaning via FlexiArm, 60 days of hands-free operation, and 176°F self-washing mops, the Saros 10R is the robot vacuum that most competing models at any price can’t match on the combination of profile height and feature depth simultaneously. The furniture it fits under is furniture that has never been cleaned by a robot vacuum before.
