Based on a review by 邦尼幫你 3C 科技 - 開箱評測 (accessed 2026-08-08).
Based on this review alone: buy it if you care about 90 d (degree) hot water and 180 d (degree) steam cleaning for tough stains — just accept steam generation requires some warm-up time (up to 1 minute 10 seconds for full capacity).
The reviewer concludes that as a super-flagship model, the Roborock F25 Ultra Steam Gen 2 delivers on all fronts, combining physical and chemical cleaning methods. It features a 25000Pa suction, anti-tangle shark teeth, AI retractable arm, omnidirectional assist wheels, AI dirt sensor, a trigger for enhanced cleaning, LED lighting, and excellent app customization.
This review provides an in-depth unboxing and testing of the Roborock F25 Ultra Steam Gen 2 floor washer. The reviewer conducts 11 specific 'hell tests' to evaluate its cleaning power, maneuverability, anti-tangle capabilities, and self-cleaning features. It examines both its physical cleaning methods, such as hot water and high-temperature steam, and chemical cleaning capabilities.
This flagship wet-dry vacuum is highly recommended for tackling stubborn dirt, oil, and pet messes, excelling due to its powerful physical and chemical cleaning capabilities. Its upgraded steam module delivers 5000mg/min steam with 5000Pa pressure, effectively dissolving dried-on stains like cooking oil and sauce, a significant improvement over previous models. The AI-powered front-lifting scraper arm ensures superior edge cleaning, successfully removing debris from wall corners that traditional machines miss. If you prioritize deep cleaning for heavy kitchen grease and pet messes, this vacuum is an excellent choice. However, if you primarily deal with light everyday dust, simpler models might suffice.
