Get the Narwal Freo X Ultra robot vacuum and mop for only $499.99 ($900 off)This offer is available from Amazon, and it comes in two stages. Narwal Freo X Ultra Narwal Freo X Ultra Our floors have never looked cleaner Powerful suction, anti-clog dirt channels and brushes, LiDAR and laser sensors, and a convenient self-cleaning base station make the Narwal Freo X Ultra one of the best robot vacuums we've seen for home users. A successor, the Freo Z Ultra, has replaced the Narwal Freo X Ultra. The Narwal Freo X Ultra has a mighty 8,200Pa suction power. I feel like the improvements don’t justify the price increase, as the Narwal Freo X Ultra is still an amazing robot cleaner.
