The Robovac from Eufy has a 2-in-1 design that vacuums and mops simultaneously, with many high-end features: It auto-empties into the home base when needed, the dust bag stores up to 60 days of debris, and the iPath laser navigation scans your house accurately to build a virtual map. The Robovac has four levels of suction with up to 3000 PA power, plus 3 water flow levels and a 200ml water tank. Climbs over thresholds and rugs up to 20mm thick.
