This is the blue exhaust filter cover for Windsor Sensor commercial uprights, Windsor part 5007BLU, now also catalogued by Karcher as 8.614-141.0. The cover holds the exhaust filter flat against its housing at the back of the machine. That sounds minor until it breaks: a missing or cracked cover lets the filter shift, and air then takes the path of least resistance around the media instead of through it. The machine keeps running and still picks up, but the filtration stage it was sold on is no longer doing its job, and on a commercial route that means the vacuum is redistributing fine dust through occupied space. Covers get broken by exactly what you would expect on a janitorial machine, doorframes, carts and being set down hard, so this is a routine wear replacement rather than a repair.
Built for
Restoring proper exhaust filtration on a Sensor upright
With the cover in place the filter is held flat and sealed, so exhaust air is forced through the media. A shifted filter is the usual reason a machine that appears fine still leaves fine dust in the air behind it.
Routine janitorial fleet maintenance
Covers are consumable on a route. Keeping spares on the shelf lets a supervisor put a machine back into service the same day rather than pulling it from rotation over a plastic part.
Bringing a used Sensor back into service
Secondhand commercial uprights frequently arrive with the exhaust cover missing entirely. Replacing it is the first step in getting the machine back to its rated filtration.

Frequently asked questions
Does this cover include the exhaust filter?
No. This listing is the plastic cover only. The exhaust filter media is a separate part and should be replaced on its own schedule, so it is worth ordering both at the same time if the existing filter is grey and loaded.
Which Windsor machines does it fit?
It is the exhaust filter cover for the Windsor Sensor family of commercial uprights, including the SR and XP series and the S12 and S15 sizes. Karcher now sells the same part under the 8.614-141.0 number after taking over the Windsor line.
Can I run the vacuum without the cover?
It will run, but you should not. Without the cover the filter can shift and exhaust air bypasses the media, which puts fine dust back into the room. On a commercial contract that undermines the filtration the machine was specified for.
Why is my Sensor still blowing dust with a new cover?
Check that the exhaust filter itself is seated and not loaded, and check the bag and its collar for a poor seal. The cover only holds the filter in place, so a bypass upstream of it will still show up as dust at the exhaust.
Discount Cleaning Products is an authorized dealer and stocks this part alongside the matching filters, bags, belts and accessories for the same machine, so a single order covers a full service visit. Orders are handled by a US-based team that works with these machines every day, and part-number questions are answered by people who can cross-check the fitment before you buy.
