Nilfisk-Alto and the Nilfisk ALTO WAP SQ550 wet and dry commercial vacuum cleaner packet of 5 paper dustbags they also fit some Festo, Hilti, Makita and Stihl branded vacuum cleaner.
They're no longer available, I suggest using SKU 60910 or SKU 302000565 or SKU GARAF1055S there's not much difference!
WAP is a very popular brand in RSA
