Device works and provides a passable suction. Assembly even for artisanal rivets like me feasible. The cleaner is like most of his peers not very handy and emptying the collection bag could have been much better resolved. Cable sucker also all share a fundamental problem: the cable. It sucks terribly.
Instrument can not just suck, but also blow and that makes it pretty neat.
For larger areas or muddy leaves not the right solution, but that is likely to apply to most wired devices.
