Cordless Wet Dry Vacuums FAQ
What is a cordless wet dry vacuum?
A cordless wet dry vacuum cleaner like the Aero Pro clears dry debris and mops up spills on sealed hard floors, with no cord to manage. Inside, a spinning roller wipes the floor while suction pulls the dirty water straight into a separate tank, so it never gets pushed around or smeared back onto the floor. Our guide explains what is a wet dry vacuum, detailing the tanks and roller, as well as how wet and dry pickup functions side by side.
Can you use a cordless wet dry vacuum on carpet?
No. It can only dry-vacuum your carpet. The wet function stays on sealed hard floors like tile, vinyl, sealed wood, and laminate, since carpet fibers and padding trap water that the machine can't pull back out. On carpet and rugs, switch to dry mode, and it picks up debris like a standard vacuum. If your home has both, the H15 Pro CarpetFlex is a good pick. Carpet gets dry pickup, hard floors get a wet mop, all in one pass through the house. Our multi-surface cleaning guide covers which settings to use on each floor type.
How does a cordless wet dry vacuum work?
A roller at the base spins against the floor to loosen and wipe up mess, while suction pulls debris and dirty water off the surface. Clean water sits in one tank and feeds the roller. The dirty water and grime collect in a separate tank that you empty after. That's how the floor gets mopped with clean water instead of dirty water that's already been used.
Does it replace a separate mop and vacuum?
For sealed hard floors, yes. One pass vacuums up dry debris and mops up the wet mess, so you don't need a separate mop and vacuum. The one job it does not do is deep-clean carpet. For carpets and rugs, it vacuums dry. Heavy carpet extraction requires a different machine.
How long does the battery last?
Up to 60 minutes on a full charge on the Aero Pro and H15 Pro CarpetFlex, which covers most single-level hard-floor homes in one go. That's in Quiet mode, the setting most homes run day to day. Switch to Turbo for stubborn spills, and the extra suction will shorten the runtime.
Is hot water mopping better than cold?
If you're dealing with grease and dried-on spills, yes. Cold water tends to push that kind of mess around instead of lifting it, while hot water breaks it down, which makes a real difference in kitchens and pet areas. That's what a vacuum like the H15 Pro Heat, which mops at 185°F, is built for. Cold water still does the job for everyday dust and light spills, so if that's mostly what you're dealing with, you may not need the heat.
Which Dreame cordless wet dry vacuum is best for pets?
Pet households require a cordless wet dry vacuum with a brush that does not tangle and is able to freshen up after accidents. The Aero Pro's TangleCut™ 2.0 roller cuts hair off as it spins, so long fur does not wrap and jam the brush, and its 194°F hot self-cleaning keeps the roller fresh between runs. If your home features both rugs and hard floors, the H15 Pro CarpetFlex is a great option — strong suction picks up pet hair from low-pile carpets and it moves seamlessly onto tile or wood for wet cleaning.
