The iRobot Roomba Plus 515 is a compact, powerful robot vacuum and mop combo built for larger homes that demand longer runtime, stronger suction, deeper mopping, and more precise navigation — stepping up from the entry-level Roomba Plus 415 with 22,000 Pa of suction, up to 295 minutes of runtime covering 2,000 square feet on a single charge, heated mop pad washing at 167°F (not just heated drying), PerfectEdge technology for true corner and baseboard cleaning, and ClearView LiDAR mapping that saves up to three floor plans for multi-level homes. If the 415 is for apartments and smaller spaces, the 515 is for full-sized family homes where a robot needs to run longer, clean deeper, and maintain itself more thoroughly.

The AutoWash™ Dock with heated wash is the headline upgrade over the 415. After every cleaning run, the robot returns to its dock where the system automatically empties debris into a sealed bag that lasts up to 90 days, then hot-washes the DualClean mop pads at 167°F — not just rinsing with room-temperature water, but actively washing with heated water that helps dissolve grease, kill bacteria, and eliminate the odors that accumulate from mopping kitchen floors, pet messes, and high-traffic areas. After washing, the dock heat-dries the pads at 113°F so every clean starts with a fresh, dry, sanitized pad. The dock also auto-refills the robot's onboard water tank for the next session.

The 22,000 Pa of power-lifting suction — a meaningful 10% increase over the 415's 20,000 Pa — pulls dust, debris, pet hair, and fine particles from both hard floors and carpets with the intensity needed for homes with multiple pets, kids, and high foot traffic. Four adjustable suction levels let you customize intensity: lower for quiet overnight runs, higher for deeper weekend cleans. Dual tangle-free rubber extractors capture pet fur and long hair without wrapping or clogging.

PerfectEdge™ technology is a significant cleaning performance upgrade. Extending brushes and mop pads physically reach out beyond the robot's body to sweep along baseboards and push deep into corners where standard robots leave dust and debris untouched. Combined with the 46% slimmer body design (compared to the Roomba Plus 505), the 515 reaches under more furniture and cleans closer to walls than its predecessors.

DualClean™ mop pads spin at 180 RPM while SmartScrub™ applies 2× deeper downward pressure on stubborn spots — breaking down dried food, muddy paw prints, and sticky kitchen splatter. Four cleaning modes provide full flexibility: vacuum only, mop only, vacuum and mop simultaneously, or vacuum first then mop for a thorough sequential clean. The robot automatically detects carpets and lifts its mop pads before crossing rugs to keep them dry.

ClearView™ LiDAR navigation creates precise maps of your home — saving up to three floor plans for multi-level houses — with obstacle recognition that navigates around shoes, cords, toys, and everyday clutter without getting stuck. You can set repeat cleaning passes for high-traffic areas like kitchens and entryways through the Roomba Home app. Voice control via Amazon Alexa and Google Assistant lets you start, stop, and direct cleaning hands-free.
