The vacuum cleaners feature an electronic keypad with LED indicators to monitor performance of the main and HEPA filters. Using an optional HEPA filter the vacuums are able to capture 99.97 per cent of particulate, including matter as small as 0.3 microns.
Nilfisk has also equipped the vacuums with manual filter shakers to allow for quick cleaning, oversized handles for easy transport and accessory storage trays and cable holders.
The two-motor S2 has a 50 litre collection container and the three-motor S3 is available in 50 and 100 litre capacities. Nilfisk has equipped the 100 litre model with liquid and solid level LED sensors that automatically shut the vacuum down when maximum capacity is reached.
