iRobot Roomba Plus 515 Combo + AutoWash Dock review

The Roomba Plus 515 Combo is the step-up pick for buyers who want the most automation without leaving budget territory. At $429.99 when we checked, its AutoWash dock empties debris, refills the robot's water tank, hot-washes the two spinning mop pads at 167°F and heat-dries them at 113°F, and iRobot says you can go up to 3 months without emptying bins. The DualClean pads spin at 180 RPM and lift 10mm before crossing rugs, and PerfectEdge extends the brush and pads into corners. ClearView LiDAR maps the home, and iRobot says obstacle recognition handles cords, shoes and everyday mess. Up to 295 minutes of runtime covers 2,000 sq ft, which suits larger homes. iRobot states suction only as 3x more than earlier models, not in Pa. It ranks fourth because it costs $110 more than our top pick and $50 more than the Dreame D30 Ultra CE. We compared documented features and published prices.
