Stuff gets stuck in the hose and never makes it to the canister

I've cleaned out all filters, made certain the roller was clean and turning. When I vacuum, all the stuff gets sucked up and stays in the hose...UGH

You must have a clog in the hose, take the hose off if you can, drop something down one end to see if it comes out the other side, if not then it is clogged. If it does, the inlet down by the brush roll may be clogged.

I cleaned the filter and emptied out the canister from the bottom and now the dirt comes out on my filter and not in the canister?

The first place the "dirty" air enters is the top chamber of the canister where it traps the bigger stuff.

The canister has two clean-out doors so make sure you open them both (top and bottom) or you could have problems.

Nice thing about the Shark as it has a number of clean-out points starting at the base of the hose where it enters the bottom of the vac. to the beater brush (on the bottom of just behind the brush assembly). Good luck!

Vacuum picks up some dirt and debris but not all, and spits some back out?

Some blockage at the pickup or in the hose if it uses one---dirt etc being kicked back out is a clear sign of this----if it has a tube check that first, and if a head with turning brush do not miss looking for a blockage there.

On the back of my lg kompressor vacuum below the retractable cord is a suction plug that keeps sucking in when the vacuum is turned on it is supposed to stay out the increase suction. what is the solution...

Remove the hose fitting on the lower back of the vacuum and you will probably find a large amount of debris lodged in the hose. That hose leads to an opening right behind the main roller brush. If you remove the brush, it is easier to remove any clogs that are inside the hose. Once you have checked that there is no clogs in that hose reconnect the hose and the brush. You should then remove all three filters and wash only the two filters inside the canister. The third filter is a HEPA filter located in a compartment on the lower front side of the vacuum. Make sure you do not wash the HEPA filter.Clean it by tapping it inside a trash can outside the house since a lot of dust will come out of it. Once the other two filters are dry, put them back inside the canister and also jake sure that the canister is empty and clean.

It's lost suction even though we've cleaned the filters. Is there anything else we can clean?

Yes. Remove the hose, disconnect all the different sections and visually check for blockages. Make sure you check the cleaning head as well. If nothing is visible reassemble by adding ONE SECTION AT A TIME and check the suction by switching the power on and seeing if the hose will stay stuck to your hand when you turn it upside down. If you find that the suction dies after re-attaching a particular section, then there is a blockage in that section. Make sure you re-connect all sections of hose fully and correctly.

Try this and report back.

I have lost suction.....what do I do? -with the vacuum and the hose!

Its okay to unscrew where the hose is connect to the area close to the bottom, where the hose bends. That is where there is usually a ball of hair, dust, and whatever. Pull the hair ball out and also clean the roller.

Nothing inn the canister after using,suctione working,bottom roller working,no air leaks from hoses.Also when running awhile it shuts off by itself,have to wait awhile to use again

I'm not sure what vacuum you have, but that sounds like a blockage to me. Thermal shut off kicks in, shutting the motor down, to prevent damage from overheating. After waiting like 1 hour it probably comes back on. Make sure hose, filters, bag (if any) is clean. All "airways" of vacuums need to be clear of any blockages, since airflow is what makes vacuums work.

Bissell Lift-Off Revolution keeps clogging

Sounds like it is partially clogged. That yellow thing you are talking about, twist it and it should come out, clean or replace the filters, then re-install it. Check the hose and make sure there isn't a clog in it and clean any other filter. One problem with this bagless is the filters will clog up fast and need to be cleaned on a regular basis. Another place a clog happens is in the inlet by the brush roll.

1. Make sure the hose attachment is pushed all the way down into its receptacle. It will click softly when it's all the way down.

2. Detach the hose from the machine. Do this by twisting the grey fitting on the back of the machine. (Note: leave the attachment end of the hose plugged into the machine) Turn the machine on. Hold your hand over the hose fitting. If there's strong suction then there is a blockage in the hose.

3. If not, check in the fitting to see if something is stuck in there. On the back of the machine there is a long clear tube that travels down the back of the machine. Sometimes larger peices of paper get stuck in there. If something is in this tube, take a phillips screwdrive, remove the 7 black screws off and remove the blockage. Reassemble and try the machine.

4. There are two filters on this machine. The one that may be clogged and affecting the suction is located below the canister in the front of the machine. Simply pull ouot the tray and reomve the grey foam filter to clean. Rinse it out with warm water then allow it to dry. Replace in its tray then slide the tray back into the machine. The other filter is the HEPA filter and has nothing to do with the suction of the unit. It is an exhaust filter and does need to be changed at least once a year. It filters the air coming out of the machine. The first few times we used ours the whole house smelled "clean". Whne a new filter is placed in the machine that "clean" snmell returns. The filters are $25 apiece at

5. As a maintainence item, remove the canister as though you were going to empty it. Place it on the ground, locate the two buttons (one clear plastic/one blue) on the front and back of the canister and remove the clear plasctic housing. This will allow you to clean the hundreds of little holes on the grey surface of the top of this section. (This looks like a circular colender.) To clean this, use an old toothbrush and scrub the dust and stuff into your grabage can. I do this once or twice a year. (Since I have a Shop Vac in the garage, I use this instead of a toothbrush.)

Hope this helps.
