I myself own a vacuum cleaner of the type 2101 for about 2000.Und who had already schlucken.Ertragen something he had a house construction or my horticultural operations example. as leaf blower or when I live out cut pieces in boxwood my passion that remains on zusaugen.Der body (filter unit) is great, but the plastic with which the filter is enclosed, is brittle rather not empfindlich.Entspricht the level of Kärcher.Wenn I price developments see, I once about since there is the Euro 11 Euro bezahlt.Ist already fierce right? Since 2000, nothing has been the quality verändert.Und now for cleaning! I 1.benutze a hand brush with stiff Kunststoffborsten.2.Ausklopfen: only with the closed side slightly anschlagen.Ich'm assuming times from (please do not take offense), that not everyone is a compressor hat.Erst from outside, then inside ausblasen.Und now about Nassreinigung.Ich not doing well should not dissuade zuraten.Man only observe what has been sucked in advance and if the filter is not completely dry, the factors are the filter verschleißen.Nicht early to mention the thorough Reinigung.Um the all prevent I have said a nylon ladies tights, specifically a nylon ladies socks überzogen.Gibt it in every supermarket already for 30 - 50 Cent.Macht much aus.Einfach zuppeln to the socks and further geht's.Natürlich not spared large Reinigung.Der cleaning interval thereby verlängert.Für coarser work as planing, sawing, etc. I have a rough dirt-ash filter vorgeschalten.Es comes a lot zusammen.Probiert it from the Nylonsöckchen.Ich would me of a comment freuen.Übrigens, I have this product not in Amazon gekauft.Ich am in the fortunate position (relationship) this filter at an agricultural machinery trade favorable to erwerben.Bis now I'm done well with my filter maintenance.
