I cleaned canister and filter and put on new belt and it still won't ****, what do I do next.?

all battery vacs work on the same principle
so you have to clean out the hose behind the brush right up to the canister.
Hoover air stick has the same problem so they changed the head so that a removable section can be taken out the hose pulled up and a bottle brush can be used to clean out the hose to the canister and behind the brush
You will have to clean out behind the brush up to the canister to fix the problem

I think you should take it into the shop and have it looked at. I also think you might want to replace the belt in the power head.

some motors have a reset button that has to be pushed to get power back to motor after over heat. it is ussually located near the rear of the motor

Probably a good idea to remove the brush and clean as best you can. Add some WD40 at each end by the plastic clips and turn by hand until they move freely. Reassemble being sure the belt is on properly.

If the usual clog clearing and filter cleaning doesn;t work-> 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.

did u check the filter above the dirt cup?

twist the yellow piece and wash the filter

I had a similar problem. Two things to try. There is a lock symbol on the canister you need to ling it up with the mark on the top (the silver part has a line on it). It can be assembles 3 different ways. Also I over looked the sticker in the back of the canister compartment indicating a filter in the top of the canister compartment. There is an orange lever there to release the filter. Hope this helps.

What is happening is the secondary filters, HEPA and the canister all need to be cleaned. This is vital. What the vacuum repair people are keeping from you is that tidbit of wisdom. This particular vacuum is picky about airflow. Pull the canister, and on the body of the vacuum on top of where the canister sits are the secondary filters. There should be a sticker explaining how to remove them. Clean them throuougly, mine was filthy. Make sure you clean the canister by unlocking it and cleaning out the micro holes and the cone end. Mine was completely plugged. Now brush the dirty side of the HEPA filter with the combo tool. Let the secondary filters dry completely (you can blow dry them on cold) Re-install everything, and the vacuum will run like brand new. I vacuumed the whole house after I completed this maintainence and it works like a champ. Don't return this vac until you clean it completely.
