Xiaomi Robot Vacuum S40C offers 5,000Pa of suction across 4 power modes, paired with LDS laser navigation that scans your home in 360° to plan efficient, accurate cleaning routes.

Its 520ml dustbin and 260ml water tank — with 3 adjustable water output levels — reduce how often you need to empty or refill, and the vacuum can climb steps up to 20mm for smoother coverage across your floor plan. Battery capacity comes in at 2,600mAh.

As the most affordable robot vacuum in Xiaomi's current lineup, the S40C keeps laser navigation and basic mopping while dropping the higher suction and self-cleaning dock of pricier models. It's a sensible entry point for anyone trying robot vacuums for the first time without committing to a larger budget.
