Vacuum Cleaner Energy Efficiency

Have you already made your spring cleaning? Even if we are not spoiled by the sun here in Münster, we have rather cloudy and gray prospects, so we can see the spring on the thermometer at least: it will be warmer at last! After the last partial white weeks in March it now seems as if the spring is now getting a real chance. Therefore, spring cleaning. This is a great opportunity for us to look at once, as it is with the energy saving with such a mischievous and clean-up action. In addition to physical energy, the vacuum cleaner in particular requires electrical energy. But how much actually?

Vacuum Cleaner Energy Efficiency

Absorbing Energy Guzzlers?

High quality vacuum cleaners with power supply via cables from Bosch, Miele or Siemens consume between 600 and 3000 watts. So there are differences with more than three times the power consumption between the models. The direct power supply from the socket allows this high consumption, which often also allows a very good suction power, but on the other hand the reason for a very loud operating noise.

There are now also some good vacuum cleaners, which do without sockets supply and usually have a lithium-ion battery. These are connected to a charging station and no cable is needed for the duration of the suction (usually up to approx. 30 minutes). The battery vacuum cleaners are usually very small and because of their cable-free mobility only the most necessary parts, which also has an overall effect on the power consumption: Only about 200 watts of such battery suction.Vacuum Cleaner Energy Efficiency 1

But does such a power consumption fluctuation really make a difference to one year? For an invoice, we start from a use of 30 minutes per week and once from an hour. This results in the following table:

Lots Of Operating Consumption-Few Operating Hours

As can be seen in the table, depending on the use and model, between € 5 and € 35 a year can be saved by using a more economical vacuum cleaner.However, it should also be mentioned that the suction force has not been taken into account here, although it can not be said that a more wattage means more suction force. Since, however, good, new vacuum cleaners cost between 70 and 350 €, it is generally not worth a working vacuum cleaner for a new to throw away. Exceptions confirm however as always the rule: Use for example due to pets its vacuum cleaner much more frequently than only for the weekly plaster and consumes more than 2000 watts, the annual saving can climb over well over 50 € and an exchange thus after a short time save money And conserve energy through less energy consumption.Vacuum Cleaner Energy Efficiency 2

Our conclusion: When buying a vacuum cleaner please look at the energy consumption, there is still a lot of outdated technology in the market for which one long term because of the high power consumption too much money pays.In the meantime, there are good alternatives to some kilowatt centrifugal pumps with the same suction power and quality. However, if you want to save as much energy as possible, a glance away from vacuum cleaners and to other household appliances such as refrigerators, washing machines or dryers or lighting makes sense, it is often worth a new purchase as up to 90% of the energy can be saved (Eg for LED lamps).

And the spring cleaning? Well, he will be coming soon-but he will also give me a good opportunity to check the water number of my vacuum cleaner and my suction behavior.Vacuum Cleaner Energy Efficiency 3
