Pudu Robotics' BG1 tops this ranking with the highest overall suitability score in the set. Built for heavy-duty hard-floor cleaning, it pairs a sweep-and-scrub system with AI-based spill and stain detection, LiDAR-plus-3D-VSLAM navigation and fleet coordination, aiming it at large logistics, retail, manufacturing and healthcare facilities. 

VIGGO's SC50 Pro Plus, built by Beijing Idriverplus, takes a close second place. It combines a 24V/60Ah battery, 72 L of combined water capacity and five vision sensors with 2D and Mid-360 3D LiDAR, targeting complicated small-to-medium commercial interiors that demand tight obstacle awareness and a fast, roughly 50-minute recharge. 

Scores reflect the supplied ranking methodology (Robot24 commercial cleaning robot dataset), not independent field-test results. Specifications are manufacturer claims; definitions of cleaning width, coverage rate and tank capacity vary by manufacturer and are not independently verified. A named deployment case study for BG1 is available from Pudu Robotics. 

Assessment: BG1 tops the ranking while SC50 Pro Plus is a close second, and both share the same top cleaning role of hard-floor scrubbing and mopping. BG1's edge shows up in raw scale: a 344 kg platform with 75 L of clean water, AI-driven spill and stain detection, and fleet coordination built in from the start. SC50 Pro Plus counters with a lighter 180 kg footprint, a denser sensor suite — five vision sensors plus dual LiDAR types — and a notably faster roughly 50-minute recharge. The choice likely comes down to facility scale: BG1's coverage and tank capacity favour very large sites, while SC50 Pro Plus's agility and quick charging suit tighter, more complex floor plans. Neither robot's IP rating or price is publicly disclosed, so procurement teams would need to request those figures directly from the manufacturers.
