Spilled a bowl of cereal and milk? In the past, that was a two-step disaster: vacuum the solids, mop the liquids. In 2026, you can clean it all in one pass with a smart wet/dry vacuum.
This category is exploding, led by the luxurious Tineco Floor One S7 Pro and the dual-roller powerhouse Roborock Dyad Pro. Tineco focuses on a weightless, premium experience with a massive LCD screen. Roborock focuses on raw mechanical scrubbing power with its unique multi-roller design. Which one cleans the sticky mess better?
The Drive: SmoothPower vs. Muscle
These machines are heavy (filled with water). How they move matters.
Tineco S7 Pro (The Self-Driving Car)
It features the SmoothPower bi-directional self-propulsion system.
How it works: The wheels have motors. If you push forward, it drives forward. If you pull back, it assists you backwards.
The Feeling: It feels weightless. You can drive it with one finger. It is incredibly easy to maneuver, even for elderly users.
Roborock Dyad Pro (The Manual Push)
It relies on the rotation of the rollers to help pull it forward.
The Feeling: It pulls forward strongly, but pulling it backwards requires effort. It feels heavier and more substantial in the hand compared to the Tineco.
The Cleaning: Single vs. Dual Roller
Roborock Dyad Pro:
Features Three Rollers (one long front, two short rear) rotating in opposite directions.
The Benefit: The counter-rotation lifts dirt and liquid faster than a single roller. It is a beast at picking up large spills (like a broken egg) in one second. It also offers true edge-to-edge cleaning on both sides (1mm gap).
Tineco S7 Pro:
Uses a single high-speed roller with MHCBS Technology.
The Benefit: It constantly scrapes the dirty water off the roller with a floating scraper blade, ensuring you are always washing the floor with fresh water. The "MHCBS" system leaves the floor drier and streak-free compared to Roborock.
The Intelligence: iLoop vs. DirTect
- Tineco (iLoop Ring): The giant 3.6-inch LCD screen has a ring that turns from Red (Dirty) to Blue (Clean). It adjusts suction power and water flow automatically. It is the best visual feedback in the industry.
- Roborock (DirTect): Also has a smart sensor to adjust power, and it features an Auto-Dispenser for cleaning solution. You fill a cartridge once, and it mixes the detergent automatically for months. Tineco requires you to pour a capful manually every time.

FAQ: Can it clean carpets?
Can I use it on rugs?
NO. These are strictly for hard floors (tile, wood, laminate). If you run them on a carpet, they will soak it with water. Tineco basically acts as a wet mop.
Does it leave the floor wet?
Tineco: Leaves a very thin film that dries in 1-2 minutes.
Roborock: Leaves slightly more water due to the double rollers, but still dries much faster than a traditional mop.
Buy Tineco Floor One S7 Pro if: You want the Rolls-Royce experience. The motorized wheels make it effortless to use, and the LCD screen guides you through everything. It is the best choice for large homes.
Buy Roborock Dyad Pro if: You want the best cleaning performance for the price. It handles edge cleaning and large debris slightly better than Tineco, and the auto-detergent dispenser is a huge convenience feature.
