Shark HydroDuo vs HydroVac MessMaster WD161: HydroDuo sprays when asked, while HydroVac also refreshes suitable rugs
Quick verdict

Differences you will notice
Dry crumbs do not always call for a wet floor
When the floor needs sweeping more often than washing, HydroDuo suits repeated small pickups. HydroVac is a washing-led machine. Decide by the job you repeat most, and don't treat the two names as interchangeable versions.
How we worked this out
Dry pickup without spray is documented for HydroDuo. The operating instructions for HydroVac require an adequate water supply for its cleaning cycle.
The same cleaning width does not mean the same range of jobs
The 9.3-inch cleaning path is listed for both, but HydroVac adds area-rug surface refreshing. If you have a washable entry rug, that surface support may be more useful than a matching width or a cordless label.
How we worked this out
This comparison pairs an equal stated cleaning-path width with different documented surface permissions. No pickup-efficiency claim is made.
Going cordless swaps cable routing for a charging window
HydroDuo is listed for up to 30 minutes and about two hours to recharge. HydroVac keeps going from its outlet supply, though its 20-foot cable has to follow the route. Emptying and component cleaning are still needed on both.
How we worked this out
Battery duration, charging time and cable length are each separate manufacturer constraints, and none lifts the limits on water, debris or maintenance.

Decision guide
How to decide
Cordless hard-floor pickup with spray only on request is the job of HydroDuo. A corded washing routine that also refreshes suitable area rugs is the job of HydroVac WD161. The names look alike, but surfaces and water use set the two apart.
Dry crumbs do not always call for a wet floor
When your floor needs sweeping more often than washing, HydroDuo fits the repeated small pickups. HydroVac leads with washing. Decide by the job you repeat most, and do not treat the two names as interchangeable versions. HydroDuo documents dry pickup without spray, while the HydroVac operating instructions require an adequate water supply for its cleaning cycle.
The same cleaning width does not mean the same range of jobs
A 9.3-inch cleaning path is listed for both, but HydroVac also refreshes the surface of area rugs. In a household with a washable entry rug, that surface support may be worth more than a matching width or a cordless label. The comparison pairs an equal stated cleaning-path width with different documented surface permissions, and it makes no pickup-efficiency claim.
Going cordless swaps cable routing for a charging window
Up to 30 minutes of running and about two hours to recharge are what HydroDuo lists. HydroVac keeps going on outlet power, but its 20-foot cable has to follow the route. Both still need emptying and cleaning of components. Battery duration, charging time and cable length are separate manufacturer constraints, and none of them removes the limits on water, debris or maintenance.
