The high quality of the vacuum cleaner VCC301 is confirmed by its energy class A. This reflects the ratio of energy consumption to the efficiency of the device. Class A means that the vacuum cleaner has very high cleaning performance with low energy consumption, which also results in significantly lower electricity usage even with frequent vacuuming. The DpuHF class A indicates that the vacuum cleaner collects up to 111% of dust on hard floors. This value is typically higher than 100% for the most efficient models, as the device also picks up dust from surfaces next to the suction nozzle. The performance class A is the highest for all home models on hard floors. The second designation, DpuC, D provides information about the device's efficiency in vacuuming carpets. The VCC301 model collects up to 83% of dust from all types of carpets and rugs with a single brush stroke, which is especially appreciated by those with dust allergies, as this is the main source of dirt and allergens. The quality of the VCC301 vacuum cleaner is evident not only in how well it captures dust but also in the clean air that is expelled from the device. The emission class A of the VCC301 model guarantees dust- and pollen-free air in the room being cleaned. The excellent performance of the device is underscored by the use of the latest HEPA-H13 filter, which retains up to 99.97% of pollutants, including dust, bacteria, protozoa, and fungal cells. The air expelled from the vacuum cleaner while using the VCC301 is as clean and safe as possible for you and your loved ones.
