Multifunctional Cleaning Kit 9-in-1 CL3

The head has a rectangular shape instead of a round bundle of bristles, so one pass covers a whole row of keys. The bristles are soft and densely set, so they collect and carry dust away instead of scattering it across the desk. Reach is handled by an extendable rod that fits into the head: without it you hold the head like a pencil for work on a small area, with the rod extended you guide it like a small broom at a distance from the surface. For a laptop keyboard right in front of you the head alone is enough, while the rod pays off with a keyboard lying on a desk, an external monitor or a shelf full of gear, where you would otherwise be cleaning in small sections with your hand right above the surface. The top side of the head carries a microfiber cloth: once the dust is swept away, just turn the brush over and wipe the display or the laptop lid without reaching for another cloth. For the deep gaps between the keys of a mechanical keyboard the head is wide, and those are handled by the earphone brush and the pen tip from the same kit.

The pen has a thin metal tip on one end and a flocked sponge on the other. The tip picks compacted dust out of a phone's charging port or out of the recesses in a wireless earphone case, where bristles cannot reach. The sponge collects fine dust and grease from surfaces where metal would scratch: the speaker grille or the seating surface of a charging case. In a port, guide the tip along the walls of the connector and without pressure, so the contacts stay untouched.

Folded up, the kit measures 153 x 55 x 14 mm and weighs 26 g. Those fourteen millimetres of thickness decide where it fits: besides a drawer, also into the side pocket of a backpack or into a laptop bag next to the machine itself. The body is made of black ABS plastic and the individual tools are stored back inside it, so no loose pieces are left in the bag. The kit contains no electronics and no cleaning liquid, so it needs no charging and no refilling.
