Blow by , on canister

Check the ball is free in the centre of the head. Check the seal on the canister. Although yours is Craftsman, they all work the same.

If any moisture has entered the vacuum at any time then this will cause a musty smell. Does the primary filter have discoloration or a yellowy stain on it? this usually indicates moisture has been present at some stage. Replacing the filter may help or you can place a small sachet of air freshener beads (glade) in the bottom of the canister under the bag. This will give a pleasant smell whether vacuuming or blowing.

If there is a hose or an exhaust port, attach that to the input valve of the mattress and make sure you seal the connection. You may have to use some duct tape. Turn on your vacuum after you use a clean bag or canister.

Yes, this uses a Bag. AF482 Starbag from Cleanstar.

if the bag is not in properly or damaged it may blow thru.

it is supposed to blow out the other hole. in order for a vacuum cleaner to suck things up, it also takes in air. That air passes thru a filter leaving the debris inside the canister, and then exits thru the other hole.

The Guardian Canister vacuums have a blow port under the filter. So you need to remove the filter (on the Guardian Ultra, you have to open the top of the vacuum) by lifting it up the forward. Then disconnect the hose from the normal suction end of the unit and plug it into the blower port. Now turn on the vacuum. If the hose is clogged, position the other end of the hose at the suction port.

For the Guardian canister, select the high, medium or low force for the motor. Then blow the dust out from under the furniture or use to fill an inflatable. Turn off the vacuum and replace the hose in the usual position and replace the filter when done.

If you are still unable to get the unit to blow out when connected to the exhaust port after attempting to clear the hose, separate the hose, wand and handle. Look down the hose for any object that might be creating a one-way valve. Remove the foreign object.Do the same with the other parts of the unit. Also replace the vacuum bag. If the bag is sufficiently full, the airflow will be reduced through the bag to the exhaust and cause the problem you describe.

The Electrolux Guardian Canister Vacuums are part of the Aerus line. The manuals for the vacuums are available here: http://www.aerusvacuums.com/support/manuals/index.cfm . The Guardian Ultra is in the current model section. The Guardian is listed in the Older Model drop-down menu.

I hope this helps.

(many canister vacuums have a blower mode when you connect the hose to the exhaust (after the bag) instead of the suction side of the unit.)

You should have two ports on the shopvac. One that is basically your vacuum and one you can use as a blower. Your hose will fit on both connectors. So yes, it would both **** and blow. This is called a "blow-through" system.

There is a round plate or cap on the side of the motor unit. this is removable to attach the hose to blow.

yes, andrea.....if only it could **** as hard as it can blow!! mine blows so hard that it blows all my fridge magnets off my fridge!!

Take off the round flat water seal, carefully, you will have to glue it back on, remove those screw to take off the bottom piece.
