The NARWAL S20 Pro is a cordless, self-propelled vacuum mop for hard floors, weighing 9.41 lb with a 0.79-litre clean-water tank and a self-cleaning, hot-air-drying dock. Vacuum Wars measured top-tier mopping, 151 points in its stain test and a combined score of 175 that tied for first, while noting low usable suction and a smaller-than-average tank. Business Insider found it picked up everything from flour to syrup in a single forward pass, cleaned flush to walls and left the brush roll dry after its self-clean cycle, but did a poor job when pulled backwards. It suits buyers who want mopping results close to flagship machines in a lighter package; anyone who cleans with long back-and-forth strokes or has rugs should look elsewhere.
