UWANT D600 Review: The Wet Dry Vacuum Built Not to Smell

Every wet/dry vacuum I have owned eventually starts to stink. UWANT built the D600 around three separate fixes for that, so I ran it through dried ketchup, a floor covered in flour, and a full house clean.

There is no shortage of wet/dry vacuums right now, and most of them share the same dirty little secret. They work beautifully for a few weeks, and then one day you pull the machine off its dock and it smells. Not the floor. The vacuum. That is the problem this UWANT D600 review is really about, because it is the problem UWANT built this machine around.

The smell is not mysterious. A wet/dry vacuum finishes every job with a damp roller brush sitting in a warm plastic housing, next to a tank of dirty water. That is close to ideal conditions for bacteria. If the machine has no way to clean and dry itself properly, the roller stays damp and the smell is inevitable.

The triple odor system, and why it is three things and not one

UWANT's answer is layered, which is the part I found interesting. The first layer is dual odor-removal sticks that sit in the water itself. The second is an IPX6-rated roller brush you can hold under a running tap without worrying about it. The third is the base station, which washes the roller with 100C hot water, runs a UVC sterilization pass, and then dries it with hot air.

Any one of those on its own would be a marketing bullet. Together they attack the actual chain of events that produces the smell: dirty water, a roller that never gets properly washed, and a roller that never gets properly dried.

The ketchup test

The first real mess I threw at it was dried ketchup on tile, which is the kind of thing that normally means a paper towel, a spray bottle and some scrubbing. I filled the clean water tank, added a capful of UWANT's cleaning solution, and let the machine start in smart mode. Smart mode reads what it is going over and adjusts suction, roller speed and water output on its own.

It came up. Not smeared around, not half-lifted with a pink ghost left behind, but gone. That is where I switched the water output to high for the rest of the floor, because the tile had not been done in a while and the extra water was clearly doing more work.

The flour test, which is the one that surprised me

Flour is a genuinely hard test for a wet vacuum. It is fine enough to work into every seam, and the moment it meets water it turns to paste. I spread it across the kitchen floor and ran the D600 over it.

It cleared the flat tile as expected. What I did not expect was the grout. Flour had settled down into the grout lines, which is normally where you give up and get a brush, and the D600 pulled it out of them. It took more than one pass, but it came out.

The floor was not the interesting part. The grout lines were.

23,000 Pa, in context

UWANT rates the D600 at 23,000 Pa of suction. Worth being straight about what that number is: Pascal ratings are manufacturer-reported and are not measured to a shared standard across brands, so they are a rough class indicator rather than a lab result. With that caveat, 23,000 Pa puts the D600 in the bracket occupied by premium cordless machines rather than entry-level ones, and the way it handled the flour is consistent with that.

It lays flat at 4.72 inches

In dry mode the handle drops until the machine is essentially parallel to the floor, at 4.72 inches tall. That is the difference between cleaning around your couch and cleaning under it. The handle can also be set to float rather than lock, which takes a noticeable amount of the machine's weight off your wrist while you push it, and you can switch it back to a fixed handle if you would rather have it behave like a normal vacuum.

You can rinse the roller housing under the tap

This is the feature I would put second on the list after the odor system, and it is the one people are most likely to skim past. UWANT sealed the motor. When something gets wedged behind the roller brush, which happens on every machine like this, you can take the roller out and rinse the housing directly under running water without destroying the vacuum.

Anyone who has stood at a sink with a wet/dry vacuum, a toothbrush and a cotton swab, trying to get gunk out of a housing they are not allowed to get wet, will understand why that matters.

The base station's four colors actually mean something

Docking is a push. There is nothing to line up, you drive the machine into the base and it clicks in, which sounds trivial until you have used a dock that needs three attempts every time.

The base is RGB-lit, and the color is a status readout rather than decoration. Green is basic self-cleaning. Blue is deep self-cleaning. Purple is UVC sterilization. Red is infrared-assisted hot air drying. You can glance at it from across the room and know where it is in the cycle.

The tissue test

This is the test that decides whether the odor system is real. After cleaning the whole floor, which was properly dirty, I docked the machine and let it run the full sequence: clean, deep clean, UVC, dry. Then I took a plain white tissue and wiped the roller.

Nothing on it. Clean and dry. A roller that comes off the dock dry is a roller that does not have time to grow the thing that smells, and that is the entire argument for this machine.

What I liked

✦  The odor system works. The tissue came back clean and dry after a full floor and a full base cycle. That is the whole reason this machine exists and it delivered.

✦  23,000 Pa is real-world enough. Dried ketchup off tile, flour out of grout lines. Nothing I threw at it needed a second tool.

✦  Push-on docking. No lining anything up at the end of a chore you already did not want to do.

✦  It lays flat at 4.72 inches. Under the couch, not around it.

✦  The sealed motor. Rinse the roller housing under the tap without fear.

✦  Speed. A whole floor in 10 to 15 minutes. We had our church connect group over the night before and the cleanup afterwards stopped being a project.

What I'd change

✦  4 to 6 hours to recharge. The 50-minute runtime is plenty for my house, but if you have a big place and you run the tank dry, you are waiting a long time before the next go.

✦  About 9.5 pounds. That is heavier than some competitors. The floating handle genuinely helps, and it is the reason this is a note rather than a complaint, but you do feel the weight when you carry it up stairs.

Buy it if your last wet/dry vacuum started to smell

That is the specific problem the D600 is engineered against, and it is the problem it solved. If you have hard floors, kids or pets, and you have already thrown out one of these machines because you could not get the stink out of it, this is the one to look at.

Look elsewhere if you have a large house and no patience for charging

A 4 to 6 hour recharge is the one spec that could genuinely bother someone. If your floor plan needs more than about 50 minutes of continuous cleaning, a corded machine will annoy you less.
