Dyson V15s Detect Submarine Wet Dry Vacuum
Verdict
The Dyson V15s Detect Submarine is an outstanding cordless vacuum with top-tier suction, tools, and smart features, plus a uniquely strong mopping head for dried-on stains and everyday hard floor maintenance. Its weaknesses with large wet spills, debris pickup while mopping, and the proprietary submarine head mean it is best for people willing to vacuum first and use the mop as a second step. If you will use both functions regularly and can live with the price and compatibility limits, it is a superb all-in-one cleaning system.
