The Narwal Flow robot vacuum, which has received a top rating of "5 stars," is currently available for 599.99 euros at Darty.com, just under 600 euros. It is highlighted as the best product in the comparison and has been in the market for a few months. However, in the laboratory, it is priced at 899 euros. The Narwal Flow is equipped with a suction power of 22,000 Pa, which is among the highest in its category, and it features an unusual mopping system designed to remove even the toughest stains on floors. The Narwal Flow is praised for its ease of use, navigation, suction power, mopping capabilities, repairability, and battery life. Its key strengths include the ability to cross obstacles effectively, strong suction performance, efficient cleaning, and easy maintenance. However, some drawbacks include a slower cleaning speed, occasional difficulty in navigating around objects, some confusing app features, and the use of non-recyclable dust bags. Despite these issues, the Narwal Flow is seen as a strong follow-up to the Freo X Ultra and offers improved filtration and overall performance. The Roborock Qrevo Curv 2 Pro builds upon the strengths of the Qrevo series by introducing a more compact and powerful robot. It features an advanced mopping system that uses hot water at 100 degrees Celsius, making it highly effective on greasy and liquid stains. The robot also boasts one of the best suction powers measured and a comprehensive charging station that ensures almost fully automated maintenance, including efficient emptying. However, some flaws from the previous model remain, such as less precise navigation, hesitation when crossing thresholds, and occasional deviation from cleaning paths. While the Roborock Qrevo Curv 2 Pro has some navigational and handling issues, it remains an excellent choice for users who value strong suction power and fully automated mopping. Its improvements in performance and automation make it a compelling option for those looking for a high-end robot vacuum.
