How To Use Car Vacuum Cleaner In House

It is completely possible to take the car vacuum cleaner to the home for use, which is nothing to question. You only need to prepare a high-quality AC to DC power adapter (that is, power converter) to convert the 110V/220V AC on the wall of your home into a 12V cigarette lighter base. But I have to remind you that in order to ensure that the vacuum cleaner can perform as well as it should, the current output of the adapter must match or even exceed the power of the vacuum cleaner. It usually takes a 10A or 120W converter to support enough suction, and it will not be hot due to overload. This solution is especially suitable for handling some delicate work, such as cleaning sofa seams, window tracks or stairs. In these scenes, the bulky vertical vacuum cleaner is really difficult to use. Of course, before you start, be sure to disinfect the suction head and empty the dust collection box, so as not to bring the old dirt from the car into the house.

Figure Out Power Conversion: AC To DC

With a car vacuum cleaner to clean the room, the biggest threshold is the power supply specifications are not right. The car vacuum cleaner is designed for the car cigarette lighter. It runs 12V direct current (DC), while the outlet at home outputs 110V or 220V alternating current (AC). To overcome this hurdle, you need a reliable AC to DC power converter. This device acts as an interface between the two, allowing your car vacuum cleaner to smoothly draw power from the home circuit. When picking the adapter, be sure to see if it has a cigarette lighter female seat, so that the plug of the vacuum cleaner can be inserted tightly.

How To Choose Ampere (A) And Wattage (W)?

The adapter can’t be bought blindly. The most common mistake made by many users is to find a low-power adapter casually, resulting in soft suction and even burning the motor directly.

120W is the passing line: in order to generate enough negative pressure, the power consumption of those car vacuum cleaners on the market is not small. A 10A (Ampere) or 120W (Watt) converter is basically the industry standard for home use.

Prevent overheating: The upper power limit of the adapter must be greater than or equal to the requirements of the vacuum cleaner. If you use a 150W adapter to drive a 120W vacuum cleaner, it is very stable. However, if you want to use a 60W adapter to drag a 120W machine, the converter will probably shut down automatically or even go on strike directly due to overheating.

Car Vacuum Cleaner In The Best Indoor “Post”

As long as the power supply is stable, the handheld advantage of the car vacuum cleaner is really much better than those bulky big guys when dealing with “local detail cleaning:

Sofa and soft-fitting gap: The slender flat suction nozzle standard on the car vacuum cleaner is simply born to drill the gap in the sofa cushion. It is to suck snack residue and pet hair.

Stairs: No one wants to drag a large vacuum cleaner to climb the stairs layer by layer. After the car vacuum cleaner is equipped with an adapter, the light control feeling will save you a lot of effort.

Window slide rails and dead corners: various special-shaped accessories of car vacuum cleaners are very professional in dealing with narrow slits such as sliding door rails or cabinet corners.

Hygiene And Air Quality Maintenance

The vehicle cleaning tools transferred to the living space, hygiene standards must keep up.

Suction head disinfection: before starting work at home, wipe the external suction nozzle and accessories 1 times with disinfection paper towel. After all, the car may have residual road salt, oil or outdoor dust, do not rub these things on the home carpet or furniture.

Prevent cross-contamination: After taking it out of the car, be sure to empty the dust box and clean the filter.

The role of HEPA filter: Now the car vacuum cleaner is basically equipped with HEPA (high efficiency air filtration) filter as standard. I suggest you check if the filter is in place. This technology is essential for intercepting tiny dust and allergens. Only when the filter is reliable, the air discharged is clean, which is directly related to the respiratory health of your family.
