BINGO loop – Advantages

Mandatory in the German VDI standard=Association of German Engineers guidelines (VDI Norm 4709-5.2.2). For decades, central vacuuming
systems have been using a “90° short safety elbow” or “safety tee-piece” behind the inlet valve to prevent blockage.

Expert Tip 1
Never install an inlet valve or a retractable hose system without a 90° short safety elbow. Otherwise blockages are easily possible
and under some circumstances your central vacuum system may become unusable. BINGO loop is the only retractable hose system
with 90° short safety elbow / safety tee-piece.

Behind the bingo door you will find a complete suction equipment. Hose with on-off switch on the handle, 3-in-1 nozzle in the handle garage and the telescopic wand.

The bingo loop hose pull-in / pull-out is based on softpull technology. It can be used in any length, at any point without annoying mechanical “locking”. The retraction is easily and conveniently by closing the suction port on the handle.

Only with BINGO loop: The hose can be completely pulled out of the pipe. This opens up completely new perspectives for planning.
It can be used throughout the house for the big “Saturday cleaning” like a “normal” central vacuum system. We recommend hose lengths of 8 to 10 meters for optimum hose handling.

The BINGO loop is closed by a convenient, smooth-running plastic door (left or right opening).

When used by hose extension with slide switch in the box. For external use of the hose with on / off switch on the handle, via low volt wiring as proven for decades.

The bingo hose has optimum sliding properties thanks to a smooth, wear-free, firmly braided special braid cover (tested for 40,000 retracting and pulling out cycles). The smooth braid offers little adhesion of dust and lint.
The hose can be easily wiped with a damp cloth if necessary. Even 12-metre-long and longer hoses slide easily out of the hose depot. Also 5 hose depot bends are possible without further ado.

The outstanding lubricity of the BINGO hose means that the hose can be comfortably operated with any type of central vacuum systems in the FAWAS range.

The hose retraction pipe is reversible from both sides, as both pipe openings are located in the wall box and are accessible. 100% safety is guaranteed on the one hand by the safety tee-piece according to VDI = Association of German Engineers guidelines 4709 and on the other by the fact that both pipe ends are in the BINGO box. If necessary, the “ring line” could be cleaned with paper kitchen towels.

Expert Tip 2
Only a reversible hose retraction pipe provides 100% safety.

Disadvantages and problems

Irresponsible is the construction of a straight entrance of the hose without handle and without 90° short safety elbow into the pipe system.
There is no safety factor in front of the pipe system. Long parts can get into the pipe system, can block it or even make it unusable.
Therefore e.g. in Germany BINGO loop ist the only retractable hose system approved according to VDI* standard.
*the norm of the Association of German Engineers 4907.

Behind the flap is nothing except an open hose! It is laborious to get the accessories somewhere and stow them away again. It is difficult to pull the hose out of the small box and mount the handle. While the hose is being pulled out, the telescopic wand brought along with the handle usually falls over. Therefore it is often then “sucked” only with the hose (with deeply bent back). But be aware: large or long parts that disappear in the hose, fly freely into the pipe system, can lead to blockages on the first tight elbow in the pipe system and in certain circumstances make the system unusable.

The hose must always be locked to suck. If then moved out too little, you have to go back to the wall, unlock, continue to pull out, lock, then only suck on again. This is very user-unfriendly.

The hose can not be used outside the hose retraction pipe. That is, often 15 meters long hoses are installed. As long as hoses are very hard to pull out and unwieldy! If more than 10 meters are pulled out, there is a large hose on the ground before unlocking, which is difficult to control when pulling in. For larger areas or more floors additional retractable hose systems or additional hoses are required. In the end very expensive.

The conventional retractable hose system is behind an up or down opening flap. When opening, the finger joints have wall contact.
The wall gets torn and dirty over time. Opening downwards, the flap hits the wall inadvertently.

The standard offer has a on/off-switch in the wall. A wireless handle is only optional at a considerable additional cost. Wireless connection has only a few disadvantages with the central vacuum cleaner. Range limitation. Battery consumption. Damage prone when the telescopic wand falls over.

Variant 1 – Unhygienic and laborious:
Hose is covered with a knitted hose sock. This “sweater” gets dirty very quickly on the floor because it attracts dust and lint. Removing and covering for washing is not possible with this system. The hose is very difficult to pull out of the retraction pipe because of great frictional resistance – the suppliers themselves warn in their installation instructions: “For 12-metre-long hoses, only 3 large bends may be installed, otherwise the hose will be too heavy to pull out of the retraction pipe.” With only 3 bends the straight stretches are infinitely long and very difficult to install, very difficult!

Variant 2 – Damaged furniture and floors preprogrammed:
Hard-hitting PVC hose without knitted sock. Totally undebatable in the living area.

Only expensive, strong units (recommended 2-motor devices with an unreasonably high power consumption today) can overcome the very high frictional resistance of the drawn on the hose “knitted hose sock”.

From the hose start it goes directly without any precaution in the pipe system into direction of suction. This allows the system to block at
one of the tight elbows, which are installed in the course of the pipe system. Since the area of the hose intake is not reversible, the system
may in certain circumstances become unusable.
