DC26 has a 5-stage filtration process:
1. Outer cyclone: as the air enters the clear bin, large dirt and debris is separated from
the airflow.
2. Shroud: the air is then directed up through the shroud, which acts as a fluff and hair
separator.
3. Inner cyclones: smaller/microscopic dust particles are then separated from the airflow
in the inner cyclones. The air flows out of the cyclone assembly and into the duct, before
reaching the pre-motor filter.
4. Pre-motor filter: traps the last remaining particles of microscopic dust, allowing only
clean air to pass through.
5. Post-motor filter: finally, as the clean air passes through the motor, it collects carbon
dust particles from the motor brushes. The post-motor filter traps these particles before
the air is then exhausted back into the atmosphere, thoroughly clean.
DC26 Filtration
The dirty air flows through the wand and hose and then continues up the inlet and into the clear bin.
The filtration process starts in the clear bin. Larger debris is separated from the airflow. The air is then directed through the shroud
and on into the smaller cyclones in the cyclone top. The air then travels down the exhaust duct before continuing through to the pre-
motor filter via the pre-filter door. It then travels into the motor housing and out through the post-motor filter, where it is exhausted
into the atmosphere, thoroughly clean.
This section illustrates the direction of airflow through DC26.

The pre-filter separates particles

Machine cutting out: thermal cut-out
If the customer is advising that the main vacuum motor power has cut-out*, complete the checks below.
*Cutting out is when the machine loses power whilst in use. If the machine becomes blocked, it may overheat and will stop due to
a thermal cut-out (fitted to the motor). The customer should follow the simple blockage checks below and allow a minimum of 30
minutes before re-using their machine.
Unplug machine. Separate extension
tube from floor tool by pressing the
release button.
Check floor tool for blockages.
Separate the wand and hose. Check
the wand for blockages.
