Vacuum cleaners with self cleaning filter

Self cleaning filter

— this function allows you to clean the main filter from dirt without removing it from the vacuum cleaner and without manually shaking it out.

Self-cleaning is found mainly in industrial vacuum cleaners (see "Product type") with filters of the so-called pleated design. However, the implementation of this function may be different. One of the most popular options is vibration systems, in which, during cleaning, accumulated contaminants are shaken off the filter into a dust collector or a separate container. After that, it can be easily thrown away. And although you still have to partially disassemble the vacuum cleaner, it is still much easier than removing the filter and cleaning it manually. Vibrating systems can be made automatic, switched on according to a schedule (at certain intervals) or by a command from a sensor that detects filter contamination and a drop in suction efficiency.

Another common type of self-cleaning system is blowing out: the vacuum cleaner is turned on in reverse, and the accumulated contaminants fly out through the hose. At the same time, for additional convenience, a special hole can be provided in the body of the vacuum cleaner, where a hose is inserted during filter cleaning - as a result, the “purging results” do not fly out but into the dust collector. Of course, such self-cleaning is activated only manually.
