Samsung Jet 90 Complete vs Dyson V15s Detect Submarine​

The Samsung Jet 90 Complete and Dyson V15s Detect Submarine​ are both cordless stick vacuums compatible with purpose-designed mopping floorheads. The Samsung's Spinning Sweeper attachment uses rotating microfiber pads to scrub away stains. In contrast, the Dyson's Submarine head features a single wet roller, along with separate reservoirs for clean and dirty water. Both floorheads are sealed off, as the vacuums they're compatible with aren't designed to suck up liquids. While both designs offer similar stain-clearing performance, only the Dyson vacuum's head can actually lift away small amounts of liquid, thanks to its separate dirty water reservoir. When judged entirely as vacuums, the Dyson also pulls slightly ahead—it's a little more powerful, has a longer battery life, and is equipped with an automatic power adjustment system.
