Aspria Premium Central Vacuum Attachment Group CV6855Our CV6855 includes everything you need to clean all surfaces in any size home. The perfect upgrade to a builders grade attachment kit, the CV6855 Premium truly lives up to its name, Premium. Suitable for cleaning all carpeting types and every hard floor surface the Aspria Premium CVS attachment kit will clean homes of every size from small condo to multi-level mansion.

Our Premium CVS attachment group is built upon the base component of any good carpet cleaning CVS: the powered brush. While a central vacuum power unit's suction motor can have as much as 5 times the power of a portable vacuum cleaner, when it comes time to deep clean carpets and rugs it is the electrically driven power brush that will contribute nearly 70% of the total cleaning performance. Not by coincidence, our Premium CVS attachment group includes one of the best power brushes available anywhere, the Wessel-Werk Model EBK340-QDC Power Brush.

Aspria Premium Central Vacuum Attachment Group CV6855 The common term "German Engineering" is only common because Germans know how to engineer like the Swiss know how to build a watch. The EBK340-QDC Power Brush is everything we have come to expect from the minds of German engineers at Wessel-Werk, surpassing both functionality and styling of the domestic power brush fare.

The Wessel-Werk EBK340-QDC has been in use for over a dozen different nameplates of canister and central vacuums both foreign and domestic for over 6 years. Finally, after a long wait (and some begging) the EBK340 has become available to the central vacuum market in the Aspria CV6855 Premium Attachment Kit. The measure by which all other power brushes should be judged, the EBK340-QDC has the power and features needed to clean carpeting of any type, and of any quantity.

There are many special components that lend themselves to the EBK340-QDC's phenomenal cleaning ability. Perhaps most importantly, the EBK340-QDC uses the most reliable power transmission system in use today: the Geared Belt Drive. Transferring the full power of the brush motor to the spinning brush (and furthermore to your carpets) is what sets this power brush apart from the others.

The geared belt (sometimes called "cogged" or "toothed", colored red in the photo below) far surpasses traditional flat belt products because it does not rely on the stored tension of rubber to transfer the motor's power to the brush roll. Aspria Premium Central Vacuum Attachment Group CV6855 Both motor and brush roll are geared and matched to the belt, which provides tensionless power to the roller for faster speed, consistent motion and the highest reliability for cleaner carpets with less effort.

Spinning the brush fast is one of the most important factors of power brush carpet cleaning. Faster brushes increase the bristle contact to the carpet fibers for better brushing action. It also increases agitation to bring embedded soil to the surface, at the same time creating an auger action that reduces the tendency to spatter, unlike slower brushes that tend to spread dirt around before it can be pulled into the vacuum's air stream.

This single feature and benefit is so important we have devoted an entire article to the subject along with a in-depth look inside the EBK340-QDC, see the article EBK340-QDC: GEARED AGAINST THE MACHINE.

Never Fail Belt System
If you have ever used a vacuum for any amount of time you will have most likely also replaced its belt, probably more than once, and perhaps several times. Most vacuums and power brushes use a flat belt made of rubber. The geared drive system of the EBK340-QDC uses a fiberglass reinforced toothed belt similar to that of an automotive timing belt with embedded fiberglass strands for superior strength.

Aspria Premium Central Vacuum Attachment Group CV6855 The geared belt of the EBK340-QDC is also the widest we have seen in a vacuum power brush and will last for many years, most likely never requiring replacement with normal use. Driven by a powerful full size brush motor with lifetime lubricated ball bearing shaft, the EBK340-QDC comes ready to work. The entire geared belt drive system is protected with a patented motor protection integrated circuit that will detect any problem in the brush before it can cause damage and will shut power off to the nozzle. No longer does vacuuming up the dog's chew toy mean you have to drop everything and run to the vacuum store for a new belt.

With the EBK340-QDC you need only remove the obstruction, plug in your vacuum and start cleaning again. Equipped with two top mounted LED indicator lights you will always know when your brush is operating correctly as with a green indicator, or when the brush action has stopped as signaled by a red light.

With some older vacuums the brush roller belt runs in "dirty air", the same path where vacuumed debris travels to the bag. The EBK340-QDC's belt rides in its own clean path, away from paper clips and staples. And because the geared belt system does not rely on large flat surface contact to drive the brush you have more space under the nozzle for cleaning brushes, plus better edge cleaning on both sides.

Aspria Premium Central Vacuum Attachment Group CV6855 The EBK340-QDC also gives us many other great features including the auger bristle arrangement that brings the dirt and debris to the center of the nozzle where it is pulled into the wide throat. Developed in an airflow testing facility, the EBK340-QDC's airflow dispersal pattern guided by a unique housing design applies even and consistent suction across the entire cleaning path.

The EBK340-QDC has other features that directly effect the use of the nozzle including the full tilt/swivel QDC connector. Allowing for a full range of motion, the nozzle connector will tilt completely back to the floor and swivel fully from left to right, allowing easy nozzle driving by the user. The nozzle connector locks into the upright position for quick parking while in use, so you can easily pause your cleaning to answer the door or move an object from your cleaning path.

Aspria Premium Central Vacuum Attachment Group CV6855 The parking feature also stops the power brush automatically, restarting again when the handle is released into the normal cleaning position. The EBK340-QDC is also wrapped in a full non-marring bumper to protect both the nozzle and your furniture without leaving marks on your baseboards.

The nozzle's bottom plate is equipped with four independent wheels. Two front "helper" wheels assist in transferring the nozzle from one surface to another, easily navigating transitions including thresholds. Set on independent and lubricated steel axles the rear wheels are over-width for smooth movement on even the thickest of pile carpeting. Differing from other nozzles, the EBK340-QDC rear wheels and axles are connected together and rotate within the nozzle's main body, similar to the rear wheels of an automobile.

No more squeaky wheels, no wheels "snapping off" their plastic mounts. Furthermore the bottom plate is void of floor damaging protrusions with all metal screw heads recessed and wheels that are covered with a soft vinyl tread. The EBK340-QDC is well at home on hard surfaces too and great for vacuuming mattresses to remove dust mites safely and easily. Aspria Premium Central Vacuum Attachment Group CV6855

Leave it to Wessel-Werk to enhance every part of the Power Brush, even the headlight. Overlooked by other manufacturers, a vacuum systems headlight can be a source of frustration for many. With a headlight on the power brush you can see the path ahead and illuminate dark areas such as under beds and behind doors or in closets - avoiding objects on the floor and shining light on spots that need to be cleaned. While other power brushes still use a regular glass bulb with a thin filament that burns out the first time the vacuums nozzle is bumped too hard, Wessel-Werk uses a fluorescent bulb that burns bright and is not subject to stress breaks. The florescent element also lasts much longer than regular bulbs and generates less heat during use. While not as critical as motor or belt design the fluorescent bulb is a welcomed advantage in the EBK340-QDC.

The EBK340-QDC is constructed with precision components, which are balanced for vibration and noise, lending to quiet use of a central cleaning system. Even the power brush body is balanced for truly straight tracking and the wide 13.5" (340mm) cleaning path remains highly mobile thanks to the full tilt, swivel connector. The EBK340-QDC is an outstanding asset for any CVS system, and will greatly increase the carpet cleaning performance of both new and older CV Systems.
