Answer: Use the following steps if your Powerforce® Helix has no or low suction: The dirt tank should be empty and the inner cyclone should be clean. Remove the tank by pressing the “Empty” button located on the handle. Over a trash bin, press the empty latch on the bottom back of the dirt tank to empty the tank. To remove the inner cyclone, grasp the squared end of the cyclone and twist it to the unlocked position. If necessary, wash the cyclone and allow to completely dry before reassembly. With the cyclone still removed, lift up on the "pull for filter" tab on the dirt tank to access the filter. Remove the foam filter. If necessary, wash the filter and allow to completely dry before reassembly. Replace the cyclone by inserting the tabs into their mating slots in the dirt tank and twisting to the locked position. The cyclone will click into place. Replace the filter and snap shut the top and bottom lids of the dirt tank. Test for suction. If there is still no or low suction, there may be a clog in the hose. Detach the hose where it attaches to the lower hose. Detach the other end of the hose by twisting left and pulling out. Run a broomstick through the entire length of the hose to clear any clogs. Stretch the entire length of the hose section by section to inspect for holes or cracks. Also inspect the lower hose for holes or cracks. If a hole or crack is found, a new hose needs to be ordered. Next, inspect both ends of the hose for cracks in the plastic. If a crack is found, a new hose needs to be ordered. With the hose still detached, unplug the vacuum and remove the screw on the lower back of the vacuum holding the lower hose in place. Pull the lower hose flat to the ground and check for clogs. If a clog is found, insert a broomstick to clear it. Reinsert the screw to reattach the lower hose. To reattach the long hose, first align the tabs on the clear end with their mating slots and twist right to lock in place. Then, reattach the black end of the hose and test for suction.
