Verdict

The Hoover HG2 Hydro Pro is an ultra-slim 2-in-1 robot vacuum and mop featuring a powerful 5,000 Pa suction motor and precise Point-Laser Navigation squeezed into a low-profile chassis measuring just 8.3 cm in height. Notable characteristics include its dual functionality with a 250ml dust bin and 300ml adjustable water tank, paired with a self-emptying base station that provides up to 60 days of hands-free maintenance, and smart control through the HG Robots app. Key advantages include an above-average runtime of up to 160 minutes per charge and its exceptional ability to slide beneath low furniture, though its overall tech package is less advanced compared to premium alternatives as it can struggle with complex dynamic environments, occasionally miss spots, or fail to accurately bypass small obstacles.
