In the area of customer service, mobile service vacuum cleaners are practical tools for special applications such as printers, computers or photocopiers, as they do not collect static charge, so damage to the devices can be avoided. Powerful motors ensure strong suction, and they are maintenance-free. This saves time and money. Stable filter cartridges are also practical, as they can be replaced simply and cleanly. Even the smallest dust particles don’t stand a chance of escaping to make the surroundings dirty. Fuses prevent the vacuum cleaner becoming damaged due to overheating.
