Ultimate Maintenance Guide to Make Your Delphin Equipment Last a Lifetime

You have made an excellent decision by incorporating a water-filtration-based cleaning system into your household routine. This type of technology not only transforms the way you remove dust from your floors, but it also purifies the air you breathe, creating a much healthier environment for your entire family. However, being a highly engineered machine that dispenses with traditional paper bags and filters, it requires a completely different care approach than conventional appliances.

The secret to making your investment pay off for decades does not lie in expensive monthly technical inspections, but in the small habits you apply before, during, and after each cleaning session. Equipment that uses water as its main barrier against dirt is in constant contact with moisture, fine dust, dust mites, and all kinds of organic waste. If we do not manage this mixture correctly, we can face performance issues, unpleasant odors, or premature wear of moving parts.

Through this detailed guide, we will walk you step by step through all the necessary routines to keep your appliance in impeccable condition. From properly managing the tank to the meticulous cleaning of the separator motor, you will learn to interpret the signals your machine gives you to know exactly what it needs. Get ready to master the art of preventive care and ensure your filterless air purifier works with the same power and freshness as the first day.

The water tank: the main barrier against dirt

The bottom container of your equipment is the battlefield where the real magic happens. Unlike traditional systems that push air through tiny pores that end up clogging, here water physically traps the particles. This means that everything you pick up from your carpets, mattresses, and hard floors ends up floating or sinking in this tank. Therefore, the golden, unbreakable, and absolute rule is to empty this tank immediately after finishing your cleaning session.

Leaving dirty water stagnant inside the container is the most serious mistake you can make. When dust, dead skin cells, pet hair, and food crumbs mix with room-temperature water, a perfect breeding ground for bacteria and fungi is created. If you let this mixture sit overnight, you will notice a strong musty smell the next morning. Furthermore, heavy sediments will settle at the bottom, creating a layer of mud that will stick to the plastic walls, making cleaning much more tedious.

To keep the tank spotless, empty the dirty contents into the toilet or a suitable drain. Next, rinse the container with warm water and use a soft sponge or microfiber cloth with a few drops of mild soap to remove any greasy film left on the walls. If you live in an area with hard water, you will likely notice white limescale marks over time. To remove them naturally, simply fill the tank with a mixture of water and white vinegar, let it sit for about twenty minutes, and rub gently. Finally, dry the container completely with a clean cloth before storing it.

Comprehensive care of the L-Lamella turbine

If the water tank is the stomach of your machine, the L-Lamella turbine is undoubtedly its heart. This small but powerful part spins at thousands of revolutions per minute to create the centrifugal effect that separates clean air from dirty water. Its aerodynamic design is what allows the equipment to run without losing suction power, ensuring that not a single drop of contaminated water reaches the electric motor. Keeping this turbine free of obstructions is vital for the safe operation of the appliance.

After several cleaning sessions, especially if you have vacuumed large amounts of fine dust, ashes, or long hair, it is normal for small particles to stick to the turbine's slots. To clean it, you must unscrew the central nut that secures it to the motor shaft. Do this carefully and make sure not to lose the nut. Once the part is removed, take it under the tap and use the stiff-bristled brush that is usually included with your equipment. Scrub in the direction of the blades, making sure to clear each channel so air can flow without resistance.

A freely breathing motor is a motor that does not overheat. Cleaning the turbine is the most effective preventive step against electrical breakdowns.

Do not underestimate the impact of a dirty turbine. If dirt accumulates unevenly on one side of the part, an imbalance will be generated during high-speed rotation. This will cause abnormal vibration throughout the machine's head and a much louder noise than usual. In the long run, this constant vibration will wear out the motor bearings, resulting in a costly repair. Get used to visually inspecting the turbine every time you empty the water and wash it thoroughly at least once a week or after heavy cleaning.

Accessories, brushes, and hoses: ensuring airflow

The performance of your cleaning system does not depend solely on the central motor; the accessories are the tools that channel that power to the surfaces of your home. The motorized electric brush, designed to beat and vibrate on carpets and mattresses, is one of the components that suffers the most daily wear. Loose threads, long lint, and human hair tend to wrap tightly around the rotating roller, reducing its effectiveness and straining its small independent motor.

To perform proper maintenance on this head, disconnect it completely from the power supply. Take fine-pointed scissors and look for the longitudinal groove that runs along the roller. Cut along this line to section all the tangled hairs and then remove them with your fingers. Also, check the small side wheels to make sure they spin freely and are not jammed with lint. Keeping the brush clean not only improves dirt pickup but also protects the internal drive belt from breaking due to excessive tension.

The main hose also requires periodic attention. Over the months, fine dust can stick to the corrugated inner walls, slightly reducing the diameter and trapping odors. There is a fantastic trick to make it look brand new: fill a bucket with clean water and a little mild soap. Turn on your machine and vacuum all the water from the bucket directly through the hose. This torrent of water will act as an internal pressure wash. Then, vacuum empty air for a couple of minutes to completely dry the inside, thus preventing any trace of stagnant moisture.

Aromatherapy and purification without the risk of bad odors

One of the great advantages of owning this type of technology is the ability to aromatize and purify the air in your home while you clean, or even while running statically in a corner of the room. By adding a few drops of essential oils to the water tank, the air expelled by the machine will flood your house with fresh and relaxing fragrances. However, the incorrect use of these additives can cause complications in the system if proper precautions are not taken.

It is crucial to use only water-soluble essential oils or aromatic extracts specifically recommended by the manufacturer. Very dense or resinous pure oils tend to float on the surface of the water and stick to the tank walls and the separator turbine. Over time, this oily film will trap dust, creating a dark, sticky paste that is extremely difficult to remove and can alter the balance of moving parts.

If you decide to use the air purification function statically, make sure to monitor the water level. When the machine runs for several hours straight, some of the water naturally evaporates. If the level drops below the minimum mark, the filtration system will lose effectiveness, and the motor could run dry. Refill the container with fresh water when necessary and, at the end of the aromatherapy session, do not forget to empty and rinse the tank just as you would after vacuuming the floor.

Smart storage and preventive maintenance

The moment you store the equipment is just as decisive as the moment you use it. Many people make the mistake of fully assembling the machine once they have emptied the water, placing the motor head directly on the empty tank. Although the container may seem dry, there is always a level of residual moisture left in the plastics and internal ducts. If you seal the system tightly, that moisture will be trapped, creating a favorable environment for mold and rusting exposed metal components over the long term.

The correct way to store your system is separately. Place the clean, dry water tank in its usual spot, and rest the motor head next to it, or if you must place it on top, make sure it is slightly tilted or resting on a cloth to allow air to circulate freely inside. Likewise, coil the power cord loosely. Avoid wrapping it too tightly around the machine, as constant tugging at the base of the plug can break the internal copper filaments, causing intermittent electrical faults.

Lastly, even if you are extremely meticulous with cleaning at home, it is advisable to schedule a preventive technical inspection every two or three years. A specialist will be able to open the sealed head, check the condition of the motor brushes, verify the internal acoustic insulation, and lubricate the bearings. These small professional interventions, combined with your excellent daily care, are the ultimate guarantee that your purifier and vacuum will work flawlessly for decades.

Fatal mistakes you must avoid at all costs

To close this guide, we will review those everyday actions that, often out of ignorance or rushing, can drastically shorten the lifespan of your appliance. The first common mistake is vacuuming construction dust, plaster, or cement without taking precautionary measures. These materials are extremely fine and absorb water quickly. If you vacuum large amounts without changing the water in the tank frequently, a solid, heavy mud-like mass will form, which can saturate the turbine and completely block airflow.

Another common mistake is the use of conventional foaming detergents inside the water tank. Never add traditional floor cleaners, dish soap, or carpet shampoo to the container. High-speed suction will agitate these products, creating a massive amount of foam. Unlike liquid water, lightweight foam can bypass the centrifugal turbine barrier and be sucked directly into the electric motor, causing an immediate short circuit and irreparable damage to the motherboard.

Finally, take care of the physical integrity of the machine while moving it around the house. Avoid pulling the hose to drag the equipment over high obstacles, door thresholds, or thick cables. Although the rolling base is designed to follow you smoothly, sudden jerks can crack the hose connection or even tip the appliance over if the tank is very full. Treat your equipment with the same gentleness and respect you would treat any high-end device, and it will reward you with a spotless home day after day.
