Eufy has been steadily refining its robot vacuum formula, and the S1 Pro represents a genuine leap forward. The headline feature is the HydroJet roller mop system—a self-cleaning, 11.4-inch roller that spins at 170 rpm and constantly refreshes itself with clean water from a dual reservoir. This isn’t a damp pad dragging dirt around. It actively scrubs floors and rinses the mop inside the station between passes, so you’re not just redistributing grime.

The 8,000 Pa suction handles carpets and hard floors with authority, pulling debris from deep pile without hesitation. The 3D MatrixEye obstacle avoidance is genuinely useful, navigating around shoes, cables, and pet bowls without getting stuck. The 10-in-1 UniClean Station automatically empties the dustbin, washes and dries the mop with hot air, and refills the robot’s water tank. You can go weeks without touching it.

One honest limitation: the station is large, so you’ll need dedicated floor space. And while the corner-to-edge cleaning is improved, it still won’t reach into tight corners as well as a handheld tool. But for daily maintenance on mixed flooring, the S1 Pro delivers a level of hands-off cleanliness that few competitors match.
