A microfibre duster on a telescopic pole, for the surfaces that are technically within reach and practically never get cleaned: the tops of door frames, ceiling fan blades, picture rails, tall shelves and the back of a wardrobe top.
The handle extends and locks so you choose the length for the job, then collapses again to a size that fits in a cupboard rather than leaning in a corner. Shortened right down it works as an ordinary hand duster for skirting boards, blinds and the gaps behind a radiator.
Microfibre is the point of the head: the fine strands hold dust against themselves instead of flicking it into the air to settle again ten minutes later. Give the head a shake outdoors when it loads up, and wash it when shaking is no longer enough.
