The SkyVac Internal 27. This vacuum is the ideal solution for mid-scale commercial cleaning projects at a height. At 1000ws and 3,800 LPM air flow, it's more powerful than a standard household vacuum, making it capable of tackling stubborn dust on air vents, beams, window ledges and electrical tracts. Working from the safety of the ground with lightweight carbon fibre suction poles eliminates the need for high access equipment, such as ladders and scaffolding. A compact and effective system engineered for everyday commercial use. The Internal 27 features a powerful vacuum head mounted on a polypropylene drum with a 27 litre capacity. Lightweight at just 7.8KGs, the vacuum sits on a robust trolley with two multi-directional front castors and two oversized rear wheels, making it easy to use and manoeuvre.
