The Nitro CMNR-QD Height Adjust Knob (part# C283-3600) is the black control on the CleanMax Nitro commercial upright that the operator turns to raise or lower the nozzle for different carpet pile heights and hard floors. It is the part a cleaner handles constantly as they move between surfaces on a mixed route.

What the Nitro CMNR-QD Height Adjust Knob does
The height adjust knob sets the nozzle and brushroll to the correct distance from the floor for the surface being cleaned — low for short commercial loop carpet, higher for plush pile or hard floors — so the brushroll grooms effectively without stalling or scattering debris. Correct height setting is what lets one machine clean everything from entry mats to office carpet with the right agitation and airflow. Because it is turned repeatedly and takes hand force, the knob and its detents wear over time.
Signs the Nitro CMNR-QD Height Adjust Knob needs replacing
Replace the knob if it is cracked, stripped, or spins without changing the height setting, or if the detents no longer click and hold so the setting drifts during use. A knob that is hard to turn, has broken off, or no longer indexes to its positions should be replaced so the operator can set the correct height reliably.
Installation and fit
Unplug the machine. Remove the retaining screw or clip on the knob, pull the old knob off its shaft, then press the new black knob onto the shaft in the correct orientation and secure it, checking that each height position selects and holds. Twin City Vacuum has sold and serviced CleanMax equipment since 1956, and every part is sourced directly from Tacony. Browse more CleanMax parts, or learn more at CleanMax.
