Auto-fill dock is a major convenience, with many citing weeks of mopping before refills in average use. A few find the reservoir awkward to handle/refill, but the concept and day-to-day automation score highly.

Water-system evidence is mixed: the dock has clean and dirty tanks, but some reviewers mention smaller tanks or refilling hassle.
