The 3-in-1 upright vacuum cleaner concept combines not only the functions of a traditional upright and hand-held vacuum cleaner, but also provides the ability to fully clean surfaces. Let's take a closer look at this concept using the Redmond MultiClean RV-UR390, which is perhaps the most versatile and functional of all the upright vacuum cleaners we tested. However, we will look at the details about the talkativeness of this model later.

* Contrary to popular belief, this is not the time limit after which the device will necessarily break down. However, after this period, the manufacturer ceases to bear any responsibility for its performance and has the right to refuse to repair it, even for a fee.
Equipment
The vacuum cleaner comes in a large gray cardboard box with full color printing. On one of its sides you can see the device in three configurations: for manual cleaning, dry sweeping and floor washing.
Brief technical characteristics of the model are shown on the sides. Here the manufacturer has posted photographs of all accessories.
Having opened the box, inside we found:
- motor unit with built-in battery
- waste container with cyclone filter
- extension tube
- electric brush for dry floor cleaning
- electric brush for furniture
- 2-in-1 brush attachment
- slot nozzle
- body of a washing vacuum cleaner with a tank for clean water
- dirty water tank with fine filter
- extension handle
- charging and cleaning base
- waste bin stand
- DC adapter
- user guide
- service book
The vacuum cleaner kit includes an electric nozzle for sweeping the floor, three nozzles for a manual configuration (two non-motorized and electric), as well as a washing vacuum cleaner body.
At first sight
The motor unit is surprising in size and shape: it looks more like a miniature electric kettle than a vacuum cleaner: a black cylindrical body, a D-shaped handle with control buttons and a “lid” that is an air intake grille.
The black housing houses a motor with control electronics and a non-removable battery. At the rear end there is a round LED display with color indication.
At the rear end there is a round LED display with color indication.
The cylindrical waste container is made of transparent plastic, through which the contents are clearly visible.
Large and heavy debris that gets into the container remains in its lower part, near the plastic tube.
Lighter — it spins along with the air flow around a cyclonic element equipped with steel walls with micro-perforation, which allows only the finest dust to pass through.
A small square HEPA element is responsible for fine cleaning. In front of it is a pre-filter made of black foam.
In the dry floor cleaning configuration, an extendable metal and black plastic tube is attached to the waste bin.
The tube varies in size from 45 to 65 cm and is held in place by a sleeve with a spring-loaded latch.
The hinge of the dry cleaning head allows the structure to bend approximately 45° to the right and left and from 0 to 90° back and forth.
In the front part there is a work area illumination unit, consisting of five bright LEDs.
The attachment rests on two large wheels covered with soft rubber and two small rollers at the leading edge. The velor rotor with a spiral pattern can be removed for maintenance and cleaning by pressing the small yellow latch.
One end of the rotor rests against the bearing, the other against the drive axis. There is only one correct way to install it.
The electric brush for cleaning furniture and clothes also has a traditional design: there are no hinges or any additional devices — only an electric motor and a rotating rotor.
To facilitate sliding over the surface of furniture and clothing, there is a scarlet velor pad on the working side of the nozzle.
The rotor of the nozzle is a design with two V-shaped rows of long, stiff bristles. For maintenance, it is removed from the housing through a hole in the end, which is closed by a round lid in the working position. You can open it with a coin, a large screwdriver, or any flat object.
The non-motorized attachments — the slotted nozzle and the 2-in-1 brush — also have a fairly simple design: we have repeatedly seen similar accessories in other similar models.
A washing vacuum cleaner — somehow it’s impossible to call such an intricate device a “floor cleaning attachment” — consists of a body, two reservoirs (for clean and dirty water) and an electric brush, which is supplied with liquid during operation
The motor block, already familiar to us, is installed in the upper part of the structure. A tank for dirty water with an air filtration system is fixed just below.
There is a shaft running inside the transparent container: through it, a stream of air mixed with dirty water and debris washed off the rotating brush enters the tank. Liquid and dirt remain inside, and air leaves the container, passing through a removable filter.
At the bottom of the reservoir cover there are contacts for the liquid level sensor. When dirty water exceeds the maximum level, protection is triggered and the vacuum cleaner informs the user that the tank is full.
The filter is an accordion made of non-woven waterproof material. It is protected from damage by a fine nylon mesh on a folding plastic frame.
Inside the tank is equipped with a plastic sieve that retains large debris. The dirty liquid is filtered through the holes, after which it can be poured down the drain, and what is collected on the grate is sent to the trash bin.
At the rear of the housing there is a compartment for a clean water tank.
The tank is made of dark transparent plastic and is secured with a latch. It has a filler hole at the top, closed with a hinged plug.
An extension handle with control buttons is attached to the upper part of the body. The round handle is inserted into the housing hole and secured with a latch.
If you need to remove the device for storage or fold it for transportation, the latch should be pressed through the round hole in the housing.
In the floor cleaning configuration, the Redmond MultiClean RV-UR390 is no different in appearance from most cordless cleaning vacuum cleaners.
In the front part of the base there is a recess in which excess water collects during self-cleaning — rinsing the brush. The station is also used as a charger, and two stands can be attached to it to store accessories.
One of them is designed for drying brushes and brushes, the second can accommodate a container for dry waste and one of the attachments.
An adapter is connected to the base, providing the device with a current of up to 0.8 A and a voltage of 28 V.
Instructions
The instruction manual is published in the form of a small A6 brochure on thick glossy paper. The quality of printing, as always from Redmond, is excellent: numerous drawings and diagrams are distinguishable down to the smallest detail.
The documentation for the vacuum cleaner begins with seven pages of illustrations that clearly explain the structure of the device, how to use it and recommendations for caring for it. Once the user studies the pictures, he can understand all the main points without having to read the text.
This information brochure contains sections in two languages: Russian and Kazakh. The Russian-language section takes up six and a quarter pages and includes a detailed description of safety precautions when working with a vacuum cleaner, instructions for proper operation, recommendations for caring for the device, a table with possible malfunctions and tips for eliminating them, as well as technical specifications and warranty information.
In addition, the documentation set includes a service book, also presented in brochure format with the same parameters.
Control
There are two mechanical buttons on the handle of the motor unit. Their purpose is intuitive: the first turns the vacuum cleaner on and off, the second switches power levels. Our vacuum cleaner has two speeds: economical and maximum. With these two buttons, the user controls the vacuum cleaner in floor sweeping and manual cleaning configurations. For the washing vacuum cleaner mode, the control panel on the extension handle works instead.
The top button is used to turn the device on and off. The middle button is responsible for the humidification modes: the first press switches the device to dry cleaning mode, the second activates the water supply to the electric brush.
The button with the image of a drop is active only when the device is installed on the base: it starts the self-cleaning mode.
The top line of the display shows error indicators including dust bin full, no water, turbo brush blocked, sensor problems, and low battery. The second row displays configuration symbols: manual or complete assembly of the device.
The round symbols in the central part represent wet and dry operation, as well as self-cleaning. The last two characters are displayed when selecting the minimum and maximum power.
Large numbers at the bottom of the display display the current battery charge as a percentage, and a colored semicircular scale below them indicates the readings of the air pollution sensor: with a small amount of dust it is green, and with heavy pollution it turns red.
Exploitation
Before use, the manufacturer recommends inspecting the vacuum cleaner, removing packaging materials and checking for defects. However, we ignored this recommendation, since no factory contamination or defects were found on our copy.
Before using for the first time, you must fully charge the battery. The device is charged only in wet mode, so you need to install it on the base station, connect it to the network and wait until it is fully charged.
The device's voice assistant informs you about the operating status, such as the start and end of charging, lack of water, problems with electric brushes and other events. The volume of the prompt sound can be adjusted or turned off completely.
The charge level is shown on the display as a percentage. When the charge reaches 100%, the device reports the battery is ready for use. After this, the vacuum cleaner can be used for wet cleaning or assembled into other configurations.
In manual cleaning mode, the RV-UR390 attracted attention with its ease of operation and lightweight design. There is a slight delay between pressing the power button and the electric motor starting, but you can get used to it. The speed shift button responds instantly.
The compact device allows you to put things in order, clean upholstered furniture, remove work surfaces, vacuum the inside of the system unit or the interior of the car.
The included electric brush effectively removes stubborn stains, such as pet hair on sofas and armchairs. We did not notice any new engineering solutions in the design of this accessory, but we were completely satisfied with its performance.
In the floor sweeping configuration, the device is not much different from conventional upright cordless vacuum cleaners.
In dry floor cleaning mode, the RV-UR390 performed predictably while remaining lightweight, comfortably balanced, and easy to maneuver in the hand. The device has a compact nozzle size, which allows you to effectively clean hard-to-reach areas, and thanks to the longitudinal placement of the motor unit, cleaning under low furniture is easier.
The telescopic extension tube makes the vacuum cleaner convenient to use for users of any height. When folded, even a child can easily use it, and the extended tube ensures comfortable operation even for tall people without forcing them to bend over.
Built-in illumination of the work area is important as it allows you to clean in dim conditions, minimizing the need to turn on general lighting in the apartment. Low-mounted LEDs help you spot and remove even small debris that may not be visible when using the main light.
However, the lack of parking for the broom is a drawback. During breaks, you have to temporarily put the vacuum cleaner down, which can lead to it falling and being damaged.
The base for charging and washing the vacuum cleaner has space for the motor unit and dust collector, but does not provide storage for the brush and extension tube. Therefore, you will have to find additional storage space for these components.
To start wet cleaning, you need to install the motor unit on the body of the washing vacuum cleaner, making sure that the clean water tank is full to the brim and that the dirty water tank is empty and clean. The containers are easy to install, easy to fill and clean, and lock securely into place.
The operating principle of a washing vacuum cleaner is similar to other similar devices. Clean water is supplied from the reservoir to the rotating rotor, covered with a soft cloth, moistening it. Together with the air flow, dirty water is directed into the waste bin, after which the air stream passes through a fine filter and leaves the device.
The difference between wet cleaning modes is that there is only one speed — automatic. The vacuum cleaner automatically switches from minimum to maximum power and back depending on the readings of the built-in water purity sensor.
The dirty liquid reservoir shaft is equipped with a blue LED. In addition to its decorative function, lighting also has practical significance, providing control over the cleaning process. For example, spilling detergent on the floor can cause excessive foaming of the liquid, which in turn can stop the vacuum cleaner from working.
The instructions clearly prohibit adding detergent to the tanks and also recommend avoiding the use of hot water, which can damage the vacuum cleaner.
The vacuum cleaner does an excellent job of cleaning on various smooth surfaces, such as parquet, linoleum, laminate and ceramic tiles, effectively removing dust and dirt. It also handles small carpet areas such as rugs and doormats. However, on soft surfaces it is better to turn off the water supply.
The level of dirty water in the tank is clearly visible, but there is no great need to control it: the tank has the same volume as the clean water tank, and it is difficult to overfill it.
The white separator, which fits onto the central shaft, allows you to filter out large debris: the liquid drained through it can be safely sent directly into the sewer, and the fragments lingering on the grate are suitable for the trash can.
After emptying the tank, it is worth checking for debris on the lid into which the upper cut of the central shaft rests, and if necessary, clean this area.
When tank maintenance is completed, fill the clean water tank, place the vacuum cleaner on the base and use the auto-clean button. In this mode, the device rinses the brush with clean water for a minute and blows through the air tract at maximum power, freeing it from accumulated debris. Upon completion of self-cleaning, the vacuum cleaner will remind you to drain the dirty water from the lower tank again.
The transparent walls of the dry waste container make it easy to control its filling.
Emptying the tank is easy: the small container is easily separated from the motor unit and can be emptied into a trash can without the risk of spilling the contents.
The debris that has accumulated on the cyclone element must be cleaned manually: in this case, you will still have to get your hands dirty.
Although the fine steel mesh of the central element retains most of the contaminants, a noticeable amount still reaches the preliminary foam filter.
Much of the dust remains on the outer surface of the disk, but some passes through it.
After several intensive cleanings, the inner surface of the HEPA element shows noticeable signs of use. Darkening is also slightly noticeable on the outer side of the fine filter, facing the engine.
We rate the overall filtration quality of the Redmond MultiClean RV-UR390 as good.
Care
To care for the device, if it becomes dirty, it is recommended to wipe the body with a damp soft cloth.
The electric brushes of the nozzles for dry and wet cleaning should be cleaned when dirty. To do this, the rotors must be removed from the attachments, any loose threads and hair removed, and then rinsed under running water and allowed to dry completely.
The manufacturer allows HEPA filters to be washed (with water only). After this, they should also be completely dried before being reinstalled. The service life of filter elements is up to 12 months, after which it is recommended to replace them.
At the time of writing the review, we did not find any available consumables for this model, but we assume that over time they will be available for purchase on the manufacturer’s website.
Our measurements
We present the mass measurements of the main components of the vacuum cleaner in the table:
| Weight, g | |
|---|---|
| Main unit with non-removable battery | 800 |
| Dust collector | 295 |
| Extension tube | 405 |
| Floor nozzle with electric brush | 745 |
| Crevice nozzle | 45 |
| Housing for wet cleaning with nozzle and reservoirs | 1140 |
In the configuration for dry floor cleaning (main unit, battery, dust container, extension tube and floor nozzle), the vacuum cleaner weighs 2245 g, in the configuration for floor cleaning with empty tanks — 3145 g. The clean water container, filled “under the plug”, holds 560 ml. Thus, the total weight of the device, filled and ready for wet cleaning, is 3705 g.
The minimum weight of the device in the manual cleaning configuration (motor unit, dust container and slot nozzle) is 1140 g.
We determined suction power when operating a vacuum cleaner without a pipe and nozzles, in two modes. The dependence of suction power on the created vacuum is shown in the graph below:
The suction power we measured was 32.8 aW in maximum mode and 18.2 aW in minimum mode.
When the stand valve is completely closed at maximum power, the overheating protection is triggered and the device turns off: this can be seen in the blue graph.
The noise level at maximum power with an attached floor electric brush is 83 dBA, at minimum power — 80 dBA. This is noticeably higher than the sound pressure level indicated in the passport data. Disabling the motor attachment does not significantly affect the volume, although it does change the tone of the sound. In the most powerful mode, our device is comparable in noise level to an average corded vacuum cleaner.
The battery life of the device depends on the accessories used and the selected power mode. The data we collected is presented in the form of a table.
| Dry cleaning attachment | Wet nozzle | Without attachments | |
|---|---|---|---|
| Minimum power | 19 minutes | 22 minutes | 28 minutes |
| Maximum power | 16 minutes | 18 minutes |
A completely discharged device “feeds” for an average of 2 hours 45 minutes with the stated 4 hours. The charger consumes up to 22.1 W, and a full cycle requires about 0.55 kWh.
Let's summarize our measurements in one table:
| Maximum suction power | 33 aW |
|---|---|
| Duration of operation at maximum power | 16 minutes |
| Duration of operation in manual mode | 28 minutes |
| Noise level | up to 83 dBA |
| Weight in dry floor configuration | 2245 g |
| Weight in wet floor configuration | 3705 g |
| Weight in manual configuration | 1140 g |
conclusions
Redmond MultiClean RV-UR390 is a universal device that combines vertical, washing and handheld vacuum cleaners. It quickly and effortlessly transforms for wet or dry floor cleaning, is convenient to operate and easy to maintain.
When we first got acquainted with the 3-in-1 multifunctional vacuum cleaner, we discovered the concept of the device, which caused a positive impression. Across all three usage modes, we didn't find any unique features or innovations that set this vacuum apart from dedicated models for hand-cleaning, floor cleaning, or sweeping. However, the ability to replace two or three separate devices with one may be attractive to many users.
Among the disadvantages of this model, we can note a not very capacious non-removable battery and relatively low suction power. However, the vacuum cleaner successfully copes with the tasks of keeping the house clean.
Pros:
- universal device for dry cleaning, floor washing and tidying up manually
- convenient control
- automatic power control in wet cleaning mode
Minuses:
- not very capacious battery
- relatively low suction power
