My analysis of this handheld keyboard for cleaning showed that it is an amazing product. The cordless feature makes it easy to move around while cleaning large areas and the ergonomic design ensures that there is no strain on the hands. The keyboard does an amazing job in cleaning even the tiniest corners and crevices, leaving surfaces spotless. The only downside is that it requires charging which can be a slight inconvenience. Overall, an amazing product that delivers on its promise..
