I have a house of 120 sqm and to date I bought all conceivable products for the household. I had heard of Swiffer products in general, and in particular Duster duster. I used it, I have needed just 2 dusters to clean the furniture throughout the house, without shaking the duster. He removed all the dust. And it is not redeposited faster than using cleansers. Congratulations Swiffer. I recommend, money and energy saving because cleaning is faster to do this.
