I have the vacuum cleaner bag type SP6 for my older vacuum cleaner "Bosch Logo BSG62023 Pro Parquet 3" bought because I've found in retail, no matching dust bags more for this model. This bag fits perfectly, instantly snapped firmly into the holder in the vacuum cleaner and does not slip like other bags that do not fit this model.
The number of pieces in the product description and product image has me a little confused at first, but the dealer sent correctly. With a minimum order of 2 x 20 vacuum cleaner bags I received a delivery of 4 packages of 10 each, that's okay. In each package 2 times 5 bags are bundled.
