The all-steel construction of today's NQS models is where the Numatic story started. We learnt from the 250 that the commercial cleaning business was rough and tough but, having said that, the majority of our early machines are still working 20+ years later. After all those years the NQS-250 is better than ever, the all-steel deep-drawn power head incorporates our patented Microtec noise reduction system; TwinFlo' performance is superb - too good sometimes - so we fitted a Hi/Lo control so you can turn the power down if necessary. The Nucable plugged replaceable cable system is standard as is the blower facility and diffuser attachment. Filtration is to our Tritex standard and the container is also a single deep-drawn steel pressing with superb 4-wheel mobility and stability. The standard accessory kit is to the same high standard, even down to stainless steel tubes and full size combination floor nozzle. Without doubt, yesterday's quality standards to which we have added many improved features - resulting in tomorrow's performance standards. The best of both worlds.
