Just so frustrating! I have only got the instruction manual for the rurbo brush but not the rest - either lost when moving or was never there?
The vacuum suction became really bad so I've changed the bag today - and yes it was full, but that still didn't help much. Then I've noticed that the 'Clean Air' large blacj filter is very dirtu/dusty and needs changing. Was very pleased to find the spare white insert in box - that's the insert. But for love no menoy I can't open the pesky box! just WHY does it have to hard?? I've triewd in the end to prize the top thin part with scissors and have broken a couple of plastic thin dividers between the circular bits/net. Still can't open. A few granules came out - not sure if I now spoiled it or is it just dirt.
If anyone can give me a clue? I ve gone on to hoover without the air fresh filter - suction is great but not sure if it's ok to do that, and also the ( just changed) bag indicator shows red.
