Main trade-off
Tineco FLOOR ONE S5
No supported carpet or area-rug cleaning.
Head-to-head
Choose Tineco S5 for cordless hard-floor washing with automatic adjustment as dirt changes. Choose corded HydroVac WD161 when you also want to refresh suitable area rugs or avoid battery charging.
Before you choose
HydroVac is the useful choice when your hard-floor route includes a rug whose care instructions allow wet cleaning. S5 cannot take over that rug step. Keep the expectation narrow: WD161 refreshes surface dirt, so a soaked carpet or deep stain still calls for a different cleaning method.
What this is based on
This follows the manufacturers' different surface permissions. It is a task-coverage distinction, with no claim about matched stain-removal performance.
Main trade-off
No supported carpet or area-rug cleaning.
Main trade-off
The 20-foot cable must reach around the actual room layout.


Compare Tineco S5 and Shark HydroVac WD161 for cordless hard-floor washing, outlet reach and suitable rugs. See how Auto mode and Stain Boost change the routine.
The useful split is cordless, sensor-led hard-floor washing versus a corded washing route that can include suitable rugs.
Winner by situation
S5 removes the trailing cable. Check whether HydroVac's 20-foot cord can follow the route.
S5 cannot cover the whole mixed-surface task. WD161 supports area-rug surface refreshing.
HydroVac avoids a depleted-battery pause. Both still need water and dirty-tank care.
S5 adjusts through Auto. HydroVac lets you select Stain Boost for a local mark.
Do not infer a dedicated dry-vacuum mode from either product's wet-and-dry label.
These are floor-washer choices. HydroVac's rug support is surface refreshing.
What matters in practice
HydroVac is the useful choice when your hard-floor route includes a rug whose care instructions allow wet cleaning. S5 cannot take over that rug step. Keep the expectation narrow: WD161 refreshes surface dirt, so a soaked carpet or deep stain still calls for a different cleaning method.
This follows the manufacturers' different surface permissions. It is a task-coverage distinction, with no claim about matched stain-removal performance.
S5 suits short, separated hard-floor jobs when moving a plug would interrupt each one. HydroVac suits a longer session when an outlet is accessible and you do not want to plan around charging. Neither specification tells you how many rooms one water fill will finish. Repeated passes and tank emptying still interrupt the job.
The comparison combines cordless S5 operation and its Auto-mode runtime with WD161's 20-foot cable and documented water requirement. Runtime is not a floor-area rating.
S5's Auto mode can change the wash while you move between a cleaner hallway and a dirty kitchen. HydroVac gives you a button for extra solution at a specific mark. That makes the choice about preferred control. The Shark's doubled solution delivery does not establish twice the cleaning result, or a win over S5.
Tineco documents iLoop adjustment of suction and water flow. Shark's 2x claim compares Stain Boost with its own normal solution delivery, not with another cleaner.

Tineco, FLOOR ONE S5
An automatic hard-floor washer for everyday crumbs and spills, with a dirt sensor that adjusts the wash as you move.

Shark, WD161
A corded hard-floor washer that also refreshes surface dirt on suitable area rugs, with an extra-solution setting for local marks.
Meaningful differences
| What changes | Tineco FLOOR ONE S5 | Shark HydroVac MessMaster Corded | Why it matters |
|---|---|---|---|
| Supported surfaces | Hard floors only | Sealed hard floors and suitable area rugs | HydroVac can add a rug-refreshing step to the route. S5 stays on hard floors. |
| Movement between rooms | Cordless | 20-foot power cord | S5 avoids moving a cable around doors and furniture. HydroVac needs an outlet route that reaches the work. |
| Power planning | Up to 35 minutes in Auto | Outlet-powered, no battery charging | S5 requires a charged battery. HydroVac removes the charging wait but still needs water and dirty-tank stops. |
| Cleaning-level control | iLoop Auto plus selectable Max | Normal wash plus Stain Boost | S5 responds to detected dirt. HydroVac lets you select extra solution for a mark. |
| After-use care | Self-clean cycle and roller air drying | Dock rinse plus tank and component care | Self-cleaning does not mean either machine puts itself away dry and empty. |
What you give up
Recommendation switch
Choose Tineco FLOOR ONE S5. S5 combines cordless movement with dirt-sensing Auto mode.
Choose Shark HydroVac MessMaster Corded. WD161 supports that additional surface and runs from an outlet.
What matters in practice
Start with the surfaces you actually wash, then choose the power and control routine that fits the route.
List the kitchen, hall and entry mat separately. S5 covers the hard-floor part. WD161 adds supported area-rug refreshing, but the rug's own care label still decides whether wet cleaning is appropriate. If your main problem is deep carpet staining, neither of these floor-washer briefs establishes the extraction capability you need. Do not buy extra surface claims that your own rug cannot use.
Trace the path from an outlet around the table and through doorways. HydroVac's cable has to follow that path. For S5, consider how often you start cleaning with the battery charged and whether your routine fits its Auto-mode limit. A cordless body removes cable handling during the job, while the corded model removes battery charging from that job. Water and debris still need attention on both.
Both machines offer a self-cleaning or rinse routine, and both still leave you with dirty water and wet components to manage. Allow space for the roller to air dry and follow each machine's tank and filter instructions. The wet-and-dry label describes messes collected during washing. This comparison does not establish a dedicated water-free vacuum mode for either model, so keep that requirement separate when shopping.
