Cyclone action is not working

Hello,

When the Cyclone Assembly on the Dyson is not spinning around, it usually means that you are loosing suction somewhere. This can either be caused by a clog, suction leak, or dirty filters. I will give you detailed step by step instructions along with pictures on how you can diagnose this.


Possible Problem # 1. Turn the vacuum cleaner upside down so the brush roller is facing upwards. I found the easiest way to work on it is to put it on a counter top or work bench. On the left hand side behind the roller brush you should see a flexible transparent hose that goes from the motor to the agitator housing. This hose actually has a lot of strain on it when the vacuum cleaner is in the vacuuming position with the handle down. When the first few series of Dyson DC07 models came out, they didn't make this hose long enough, so when the handle was in the reclined position, it would put too much stress on the hose, and cause the hose to actually crack, usually right where the end of the hose that goes into the agitator housing. Examine your hose and see if you have any visible cracks in this hose. If you need to you may just remove the entire hose assembly by pulling on it. It will easily come right out of the machine so you can inspect it better. Here's a picture of where the hose usually cracks:



If you do find a crack in this hose, the this hose needs to be replaced. Here's a direct link to that hose on our GoVacuum website.

Possible Problem #3. Dyson's in general are prone to clogging. There are a few clog ports throughout the vacuum cleaner that were added there due to Dyson prototypes becoming clogged at these points. Here are pictures of how and where to check for these clogs. Simply remove the suction port covers at both of these locations:




Possible Problem # 4. The Dyson DC07 has two filters on the vacuum. The first filer is the pre-motor filter. This filter is located on the right side (if you're standing in front of the vacuum) underneath of the of the cyclone assembly. There is a filter catch that holds the filter and the filter bracket in place. Simply press the filter latch, and remove the plastic circular part that comes off. In side of this plastic part you'll find the pre-motor filter. This filter is washable, but if it hasn't been washed recently, this could be the source of your suction loss.

The second filter in your Dyson is the HEPA filter. The HEPA filter is also known as the post-motor filter, or it's located after the motor. This filter typically doesn't have any effect on the suction, but you should periodically open it up and take a look at it. Despite the bogus claim of a Lifetime HEPA Filter. As you can see in the picture below, this filter gets filthy. When this filter is this dirty, it prevents the air flowing through the filter, which causes the air to look for other ways to escape, causing the dirty air to escape unfiltered. A dirty filter can also take away from the life of the motor. Here's how you can access the HEPA filter.

First remove the dust bin completely from the vacuum cleaner. Take a flat head screw driver, Cyclone action is not working - de80f32.jpghere the dust bin was sitting you'll see a groove. Put the flat head screw driver, and pry this groove off. Here's a picture of that:

Also on both the left and the right side, there are two more grooves that need to loosened before the filter can be removed:



After loosening three grooves, onCyclone action is not working - 2ab58ca.jpgont, left and right sides, the HEPA Filter cover can be removed. Inspect the filter to see if it's dirty. Here's a look at what a dirty filter looks like compared to a brand new filter:
