try completely cleaning it out and clean the filter or get a new one. sometimes when my vaccuum has low suction theres dirt clogged in the hose or the vaccuum itself. try cleaning it out and if that doesnt work try and see if the settings are messed with (if there are different settings of course)

I love the Dyson (DC07), but after 7 or 8 years it lost suction and needed some attention beyond filter cleaning. After much online research I found the few bits of advice that for me were the holy grail. After all of the standard stuff, clear clogs, clean filters etc..... In this order: 1) Remove & empty the canister, ***important****-leave the canister bottom lid open. 2) remove the three star screws at the top of the canister. It'll take a bit of pressure to pull the top up, there's a rubber seal. When you pull it up there will be a rod running down into the canister, leave it be, just pull up the top high enough to clear out any debris. 3) Put the top back on aligning the screws, when you lower it make sure the bottom of the rod engages with the hole at the bottom center of the canister, this is why you left the bottom lid open. Put the three star screws back in. 4) Turn the canister upside down, lid open, and keeping in mind this is thin plastic, gently tug upwards on the four fins that surround the bottom rubber seal. This part is held in by friction, so work your way around the four fins gently pulling until you work the ring they're connected to free. This will give you access to the inside of the canister. 5) remove the round perforated section by tugging upwards on it, set it aside with the fin part. 6) Take the canister to a laundry tub or large sink and holding it bottom up fill it with hot/warm water. Grasping the center section shake it vigorously and turn it upside down while shaking and a bunch of sh*t will come out. Repeat several times. 7) Dry thoroughly, you might use a hairdryer held to the center tube, but only if you can switch off the heat and use air only. Make sure its 200% dry, water will kill your machine 8) clean and replace the round perforated section 9) replace the fin section, I'd suggest pulling the round rubber part off of the fin part and setting it in place on the canister first, then follow with the plastic fin part. If you don't do it this way the rubber won't seat properly and the bottom lid won't close. 10) Close the lid, replace the canister, and staaaaaart suckin like it's brand new.

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.

you should check the round filter casing on theleft and the right side of machine to make sure they are snaped in right also the clear hose on the bottom sumtimes comes unhooked.

replace belt clean / replace the filters especially the one on the front just below the tank and there's another inside the upper tank it twists off

you might have a clog, to try and unclog the lines, you need to unplug the unit, and remove the bag compartment. Then take a shop vac using the hose attachment hold it into the attachment door where there is low suction and try to draw the clog out the way it went in.

Check where there is suction...is there good suction at the hose...at the back of the vacuum. Knowing where there is good suction will help you know where there might be a clog or any resistance. Bissell also has a fairly good customer support line...I believe the phone number might be on the vaccuum possibly in the back.
