Dealing with Clogged Canister Vacuum Guide

Following are the steps users can easily follow by themselves when the canister clogged:

  1. First turn your canister vacuum on and have appliance setting adjusted with use of hose. In case if there is no suction power or if power breaks down, there may be some problem with your vacuum power cable. Check for any damage and arrange for replacement if required.
  2. Once you have checked power and have tested suction coming from the vacuum cleaner. Now you can begin solving the problem of clogging by identifying how much suction power has been reduced. We will move forward step by step for assessment of clogging problem area.
  3. Check the hose for any possible clogging. In order to do that you need to detach the hose from vacuum cleaner and held it perpendicular to ground. Hose is usually the area that gets clogged in a canister vacuum. Check with your eye and if you are unsure try passing a solid thing such as coin from hose. Make sure that the size is reasonable to pass through hose. If you find that the coin pass through hose without any hindrance it means that the hose is clear and there is no clogging in this area.
  4. If hose is not the problem area, you can now move to check the dust bag or chamber connection. Whether you have a bagged vacuum or a bagless, in both cases you should check the connection that lies between hose and the place for dust/dirt collection. Try to reach that area and feel for any clogging. If you find that there is some clogging, try to clear it up. If you are unable to clear it with hands, you may use a pipe cleaner with care for clearing it. Twist the hose to make sure that you end up clearing the area completely.
  5. Now that you have tried clearly up, reassemble these parts of canister vacuum to check. Reassemble and turn the power on. If the vacuum is offering complete suction power and is working properly then you have detected the problem area correctly. However even after clearing hose you are witnessing reduced suction power, you need to check further for problem area in your appliance. Be more vigilant and check other areas for possible signs of clogging by following these steps.
  6. Check canister vacuum bags and replace filled ones. Clogging of a canister vacuum can also be because of an over-filled dust bag. A completely filled dust bag would give you reduced suction and thus vacuum wouldn’t capture dirt and dust well. Vacuum cleaner operates with air passing through bag to capture particles. If the pores do not have any space to allow flow of air, your vacuum cleaner will suffer from intense pressure on its motor that hinders suction power and thus working of a cleaner. It is important to check dust bag and filters. If the dust bag is filled more than half of its capacity, it is best to dispose all the dirt and dust before using vacuum cleaner. Filters and bag replacement must be done according to recommendations by manufacturer. If filters and bags are not problem areas, more to next step.
  7. Unplug appliance with the use of a screwdriver and remove cover that holds brush assembly. Place vacuum horizontally and look for any clogging of dirt, dust or hair under the area. Check all these areas with fingers and clear up any accumulated dirt. You can use a pipe cleaner for areas that you cannot clear with fingers.
  8. Now that you have checked the brush assembly and are satisfied with clearing it up. Reassemble it and check appliance again by turning the power on.
