A vacuum belt almost never announces that it has failed. It stretches, it glazes, it starts slipping on the pulley under load, and the brush roll quietly turns slower and slower until the machine is pushing dirt around rather than lifting it. On a commercial route that shows up as carpet that looks worn in the traffic lanes and complaints that the vacuums are not working, long before anyone opens a machine up. This is the genuine round clear belt for Koblenz commercial uprights, part number 12-0814-01-7.
Built for
- Janitorial contractors running Koblenz uprights on nightly accounts
- Schools, churches and offices maintaining their own equipment
- Scheduled preventive maintenance on a fleet rather than repair after failure
- Any Koblenz upright that has lost brush agitation or smells of hot rubber
- Keeping spares in the closet so a broken belt does not cost a night's work
Change belts on a schedule, not on failure
The useful habit with round vacuum belts is to replace them on the calendar instead of waiting for one to snap. For optimum performance you should change belts at least every 12 months, and heavy nightly use shortens that considerably. A belt that has gone slack costs you cleaning performance every single night it stays on the machine, and unlike a broken belt it gives no obvious signal. Buying several at a time and changing them all at one service interval is the approach most fleet operators settle on.
What it fits
This is the rounded, clear belt used across the Koblenz commercial upright line that takes a round belt, listed for the U210 and U812. Distributors also list the same part number for other Koblenz commercial uprights including the U310 and the U-40, U-75, U-80 and U-90 machines. If you are unsure, pull the old belt and confirm it is round in section and clear rather than flat and black.

Frequently asked questions
How often should this belt be replaced?
At least every 12 months for optimum performance. Machines used nightly on commercial accounts benefit from a shorter interval, because the belt stretches long before it breaks.
How can I tell the belt is worn if it has not snapped?
Look for a shiny glazed surface, a belt that is visibly slack when the machine is upright, or a brush roll you can stop with light hand pressure while the motor runs. A burnt rubber smell is a late-stage symptom.
Is this a round belt or a flat belt?
Round and clear. Koblenz uses this style across its commercial uprights. If the belt you removed is flat and black, it is a different part.
Will it fit a Koblenz U310, U-40 or U-80?
Distributors list the same 12-0814-01-7 part number for several other Koblenz commercial uprights including those models. The listing here is for the U210 and U812; check your machine's parts list if it is not one of those.
Do I need tools to change it?
On most Koblenz uprights the belt is accessible through the brush roll cover and changes by hand. Unplug the machine first and check that the brush roll ends are seated correctly before running it.
Discount Cleaning Products supplies Koblenz replacement parts alongside the bags, filters and janitorial consumables that go with them, with US-based order support.
