The Little Wonder High Performance Vaccuum clears and collects stones, bottles, cans, debris and other material that would normally have to be swept up by hand, saving valuable time and man-power resources. The nozzle height automatically adjusts - no need to stop the engine and change height settings to avoid 'scalping' and 'digging in' on rough terrain. The unique Debris Collection bag - dust direction system reduces clouding and redirects dust away from operator. The bag itself is very easy to unload. The Little Wonder High Performance Vaccuum's advanced impeller design and welded steel housing reduces noice for "smoother air flow".
