• Low-profile design ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.8
  Reviewers highlight that relocating the lidar to the robot’s front keeps the S1 Pro unusually low in height, letting it glide under many sofas and cabinets that taller turret-style bots miss and reducing how often it gets hung up on furniture.
• Streaking / Residue ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.8
  Owners and tests report that the S1 Pro’s roller mop leaves very little streaking or sticky residue, producing a uniform, polished finish and tracking far less mess than pad-style mops even in demanding smear tests.

• Emptying & Mess Control ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.5
  Reviewers find the S1 Pro’s dock reliably empties typical dust and debris from the on-board bin into a high-capacity bag while its self-contained wash tray keeps most of the dirty water and gunk inside the system, so owners mainly see light dirt buildup at the front lip.

  Battery performance is generally strong, and the S1 Pro’s faster-than-previous charging lets it get back to cleaning more quickly between large jobs, improving whole-home coverage.

  Although the S1 Pro has a front camera for navigation and manual driving, it does not offer a live video feed in the app, reducing the privacy concerns associated with internet-connected vacuum cameras.
• Under-Furniture Pickup ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.5
  Thanks to its low profile and front-mounted lidar, the S1 Pro can slide under many sofas and cabinets that block turret-style robots, improving coverage in tight, low-clearance spaces.

• Mop lifting system ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 3.7
  The S1 Pro automatically lifts its roller when it senses carpet and usually keeps small rugs dry, but thicker carpets still benefit from no-mop zones and some users report brief contact at edges or occasional mapping glitches.
