The screens on cyclonic units can also be messy and difficult to clean. These units allow dirt to pass through the motor fans which can reduce their operating life.

A cyclonic vacuum unit does not have a filter or disposable bag that air passes through. These units have 1 or 2 cones that create a "cyclone" inside the unit. Heavier debris is forced to the outside of the can and drops into the dirt can. Lighter debris and air stay towards the center, pass through the motor fans and are exhausted. Cyclonic units must always be exhausted to the outside because some light dust is exhausted. A screen protects the motor fans from any large piece of debris that could damage the motor. This screen needs to be cleaned periodically

What would happen should your motor start suffocating? Within 30-60 seconds, it would rev up to a screaming decibel level, and a lot of back pressure would build up.

It would start violently vibrating and quite possibly fall right off the wall, and if it landed on anything flammable like cardboard or paper...well, you'd have a problem on your hands. It could potentially cause a catastrophic failure and most likely will destroy your whole central vacuum unit. The motor is considered the "brain" of the unit, and just like humans if the brain is not getting enough air it will die. It could turn into a fire safety nightmare. There's always the possibility, so taking the proper steps now will save you from any problems later.First, to make the initial venting opening, you have to drill a 2 1/4" hole from the inside of your house to the outside. Another big problem with outside venting is flooding.
