Roborock Saros 20 Sonic

The Saros 20 Sonic squeezes flagship power into a 3.1-inch ultra-slim form using RetractSense navigation technology. The VibraRise 5.0 mopping system vibrates at high frequency to scrub dirt from grout and tile seams, matching the aggressive cleaning you'd get from the larger Saros 20. It's the only ultra-slim model that doesn't compromise on deep cleaning intensity.

Homes with narrow clearances below beds or sofas finally get access to flagship technology. If space is at a premium but you refuse to settle for weaker cleaning, this model delivers both the compact footprint and the scrubbing power most slim robots sacrifice.
