Dust?
Aye, where does it come from?
Ours, as a holiday home, so is shut up tight for up to five months.
On going back, as I go round getting the water and leccy set up, opening shutters etc, wife is busy in her wheelchair wiping every horizontal surface she can get to with neutral wet wipes.
We have THREE Vax cylinder vacuum cleaners, all bought second hand, one which was bought for parts and I fitted a new motor, all have cloth emptyable, washable bags and a supply of clean filters.
They are excellent for any renovation work, although the suction is so powerful that if I don't pick up big bits, they can block their hoses.
Three?
They are so heavy we have one for each part of the house.😄
And guess who has to do the hoovering?😁
