The Ultenic AC1 Cordless Wet Dry Vacuum Cleaner

Earlier this year, I reviewed a cordless vacuum that simultaneously mopped my floors. This proved to be an easy-to-use device that saved me a great deal of time.

Today I am evaluating a competing vacuum mop from Ultenic. While similar in design to the last model I tested, the AC1 features an intriguing self-cleaning system.

The Ultenic AC1 is 9.5 inches deep, 10.9 inches wide, 44.5 inches tall, and weighs about 11 pounds. Its shell is composed of white plastic with gray accents.

Enclosed within the base is a 2.5 x 10.25-inch roller brush covered with a thick layer of microfiber. This brush mops the floor while pulling debris, spilled liquids, and dirty water toward the vacuum opening.

The main body of this device is fitted with a vacuum motor and a display. It features two removable plastic tanks which are used to store clean and dirty water. A pushbutton-equipped handle snaps snugly into place atop the main body.

Clean water is fed to the roller brush. As this brush rotates quickly, cleaning the floor, the resulting dirty water and debris are sucked upward and stored in the dirty water tank.

The package includes a plastic stand that is fed power via an AC adapter. When the vacuum is firmly seated atop the stand, its 4000mAh battery will be topped up to a full charge. Power is also fed to the stand’s built-in fan and ultraviolet lamps.

After cleaning my floors, I place the AC1 on its stand to recharge. Then I press the self-cleaning button. Water will be fed to the brush during a programmed routine that instructs the device’s motor to rotate the brush at varying speeds. Then the stand’s fan and ultraviolet lamps will slowly dry and sterilize the AC1’s roller brush.

The Ultenic Home application can be used with the AC1.

A motor powers the roller, which washes the floor while sweeping spilled liquids and solids toward the suction input.

The debris is then vacuumed into the AC1’s dirty water tank. Liquids settle at the bottom, but much of the solid waste becomes trapped atop a removable plastic platform that fits within the tank.

A HEPA filter at the top of the dirty water tank allows air drawn through the vacuum to continue to its ventilation point.

A second tank holds clean water. This water is fed to the roller below, allowing the AC1 to mop the floor effectively.

I usually select the Smart cleaning mode, which automatically adjusts suction and water output according to the conditions noted by the vacuum’s sensor. The Max mode will increase suction and water output. In Suction mode, water output is terminated, allowing the AC1 to operate as a wet/dry vacuum.


The roller brush can be cleaned if the AC1 is placed on its stand and the self-cleaning button is depressed.

As water is fed from the clean water tank, the roller rotates at varying rates of speed, scrubbing the already clean floorboard of its stand. The resulting dirty water is vacuumed into the dirty water tank.

Then the stand’s fan and ultraviolet lights begin to operate. During this lengthy process, the microfiber roller is dried and sterilized.


The Ultenic Home Application

This application allows the user to optimize the amount of water dispensed, monitor the cleaning status, and retrieve operational and troubleshooting information.

The Front Porch Test

My sun porch was dirty but not disgustingly so. I added to the problem by scattering a few handfuls of kitty litter.

Then I powered up the Ultenic AC1 and toiled away for 10 minutes, cleaning my floor. The vacuum maneuvered easily, although I did have trouble reaching and cleaning the entire space beneath my chairs and table. This is a common problem with devices of this type. If you lower the handle enough to reach fully under a chair, water will leak from the water tanks. Happily, my wicker furniture is light enough to move out of the way.

Kitty litter can be difficult to vacuum. The AC1 handled it well, although I was required to sweep over a few heavily sprinkled areas a couple of times.

The floor, composed of poorly chosen and improperly fitted laminated wood tiles, cleaned up nicely. However, I would have completed the job more quickly if I had added a capful of the provided liquid detergent to the tank.

This task depleted 75 percent of water stored within the clean water tank. If I were to clean my entire house, I would need to refill this tank—a simple job—several more times.

The dirty water tank was about one-quarter full, and I suspect it would not require dumping until the battery ran down. At this point, the battery level had dropped to 80 percent.


Although the self-clean function will automatically clean and dry the roller, the dirty water tank must also be removed, dumped, and washed.

The first step is to pull off the top section of the tank. While the reservoir will be filled with dirty water, most of the debris will be piled atop the lower platform of the top section. This disgusting mixture can be dumped into a green bin.

The next step is to remove the HEPA filter, wash it, and set it aside to dry. Then clean both sections of the dirty water tank. The tube fitted inside the reservoir can be scrubbed with the round brush provided with the vacuum.

The entire cleaning process can be completed within five minutes.

Overall Impression

Ultenic was generous with supplies; the package included a spare HEPA filter, a spare roller brush, and a decent-sized bottle of detergent.

This vacuum is well designed, and its construction quality is appropriate for home use. Initially, I felt the vacuum’s handle was poorly conceived; however, during my test, its flat ribbed construction did not bother me.

Battery life is good. Although I would have preferred a slightly larger water tank, removing and refilling this reservoir is a simple task. This device is incredibly convenient because it vacuums and washes my floors simultaneously. The Ultenic AC1 cordless wet dry vacuum is recommended.
