FAQ

 
My vacuum doesn't have good suction. What do I do?

  1. The safety screen(lint screen) or electrostatic screen (if applicable) may be dirty.  The electro-static screen can be cleaned by vacuuming, tap water rinsing, or dousing in an ordinary detergent solution.  NOTE:  before replacing the electro-static screen be sure it is DRY.
  2. The dirt canister or bag may be full.
  3. If you recently replaced the plastic bag in your cyclonic unit, make sure the bag is touching the bottom of the can and is flush against the sides of the can. The bag may have a hole or tear in it.
  4.  Make sure the dirt canister is attached correctly. Replace the dirt canister by slipping the rim of the dirt canister over the lip of the top can until it is seated against the rim gasket. Then while holding the canister in place with your knee* (see Figure 1a), fasten the two latches. Do this by hooking the top lip of each latch over the rim of the top can and then press straight in on the bottom of the latches until they lock.
  5. The exhaust vent (if applicable) may have an obstruction.
  6. The hose may be clogged. (see below)
  7. There may be a clog in your tubing. (see below)

How do I know if I have a clog in my hose?

 Connect your hose directly to the dirt canister.  If the hose has normal suction, you do not have a clog in the hose.  Reduced suction when connected to the dirt canister means a clog in the hose.

How do I get a clog out of my hose?

Starting at one end of the hose and working towards the other end, press the hose to try and feel for the clog, when you find it, press down on the obstruction and gently knead it.  This may break the clog up so it can pass through the hose.

Remove the hose from the inlet, push a DRY garden hose though through the vacuum hose to push the clog out.

How do I get a clog out of my tubing?

Check inside each inlet, occasionally, an object gets stuck directly inside the fitting and you can remove it with your fingers.

Plug the vacuum hose into each inlet.  Put your hand over the end of the hose to create a seal, then pull your hand off the hose.  Do this a few times and it may loosen the clog and send the obstruction to your dirt canister.

Try running a plumbers snake though the inlet to push the clog out.

Can I use my central vacuum as a wet vacuum?

 The only way you can use it as a wet vac would be if you purchase one of our wet pick up kits.

What can I do if my power unit won't come on?

  Check the breaker in your electrical panel.  Also check the reset button on the canister.

How do I know my unit model number?

 This is located on a white or silver label.  The model number will generally starts with S, P, or SR.  If your unit is in a corner and you cannot view the label try using a small mirror to view the label.

What hose and brush are compatible with my vacuum?

This is a common misconception.  Your hose and brush compatibility depends on the type of inlet and wand(s).

Will any of the attachments fit my old hose/wands?

Any straight suction attachments (air turbine brushes, dusting brushes, etc.) will fit old hoses and wand.

My hose is shorting out. Do I need to buy a new hose/electric brush?

Check the connection between the handle and top wand for arching.  If that looks fine, check the hose for exposed wires.

How can I tell the difference between pin jack and microswitch valves?

Open the valve door and feel the top of the valve hole.  If you feel one ball bearing then it is a microswitch valve.  If you feel two brass pins then it is a pin jack valve.
