How they differ in real use
Built from our wet dry cordless scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the Dreame H15 Pro and the Shark HydroVac MessMaster WD261 made our Top 5 Wet-Dry Cordless Vacuums, at #3 (best premium) and #5. Largest tank capacity at 0.9L reducing refill frequency. 185°F hot water plus a 212°F self-clean cycle improves cleaning on grease and sticky residue. Shark discontinued the HydroVac Cordless Pro XL that previously held this spot: Amazon lists it as "Currently unavailable," with no restock date, on multiple regional storefronts. The HydroVac MessMaster WD261 is Shark's current in-stock successor in the same 3-in-1 vacuum/mop/self-clean line, adding LED headlights and an LED status display, though its 23-minute battery and 0.5L tank are the shortest and smallest in this list.
