Vacuum line can be rubber, PVC, or silicone. Vacuum hose is capable of handling 25psi, and is designed for vacuum, windshield washer fluid, and radiator overflow use. Vacuum line is just rubber, no cords. It is good for basic non-volatile fluid transfer and air.
Scope out all the vacuum lines under the hood. Then start the engine and spray each connection with a light stream of water. If a connection sucks in the water, you`ve found your leak. A vacuum leak can cause a rough idle, high rpm, poor gas mileage and even trigger a check-engine light.
At idling speed, an engine at sea level should show a steady vacuum reading between 14 in. and 22 in. Hg. A quick opening and closing of the throttle should cause the vacuum to drop below 5 in., then rebound to 23 in. or more.
Because standard household piping is typically ½ inch in diameter, most homeowners only need a standard garden hose size of ½ inch in diameter. A 5/8 inch diameter garden hose size may also work for you, but you`ll likely be adding unnecessary weight with this size hose.

.A clog in the hose, UR or canister. Detach hose. Drop small coin in one end and lift hose causing it to roll out the other. If it does, no clog in hose. Drop same coin into hose opening on power head. If it rolls out, no clog in PN.
.Broken fan blades, UR. Needs to be taken to shop for repair/replacement.

.You can try holding the wand end of the hose directly to the CV in port and turning the machine on. This provides essentially the same action as the previous method.
.If neither of these work, try a combination of the two. Or using a shop vac, hold the wall end to the exhaust of the vacuum and the wand end to the in port of the shop vac. Turn shop vac on and the obstruction should come out.
.Borrow a good strong shop vacuum if you need to.
.If these methods fail, take it to an authorized Aerus Electrolux store and have the service tech try to clear it. Care must always be taken when trying to clear an obstuction with a long object, especially if it’s pointed. I’ve seen many hoses that have shorted out and even caught fire due to the wiring accidentally being “nicked”.
