Because a lot of bags fewer vacuum cleaners are quite a simple design where dirt can easily be stucked into a chamber that contains the main filter, their suction relies heavily on keeping that filter clean.
The basic design of the Nilfisk Combat Filter is very similar to a car air filter. It is essentially a cylinder shape with the filter material being folded over many times to increase the effective size of the filter. This folding produces a series of V-shaped valleys in the filter. These valleys are where the dirt collects and begins to restrict the airflow.
The Nilfisk Combat Vacuum has a fundamental semi-self cleaning mechanism, but it is only useful if you use it each time you empty the dirt chamber. If you look at the top of the dirt canister, there is a large dial hold the chamber still and give the dial a few turns over a bin. What this does is like flicking the inside of the filter to help dislodge the dirt.
The most efficient way to prolong the life of the Nilfisk Combat Filter is to subscribe to Nilfisk Combat maintenance and get the machine checked up on a regular basis and repaired when necessary. If you can still see dirt and debris on the filter, you may also need to clean in between the folds of the filter with a tiny brush. The brush is efficient, and as a vacuum technician, we have done these hundreds of times in the past.
If the filter is blocked, we do ask the customer to purchase a new one or give it a good clean themselves. What we found out is that if the dirt is not coming out by tapping it, then it will be difficult to get them out.
The thing you have to remember is that this filter is the one that allows lots of fresh air into the motor to keep it cool. If the air is not getting through because of a worn or blocked filter, it will cause the motor to run hotter than it was designed to. This will, in turn, result in it wearing out the carbon motor brush much sooner than expected. The cost of repairing Nilfisk Combat filter is certainly less than the cost of replacing the motor or the whole machine.
Here at Vacuum Doctor, we have been servicing these machines in the last couple of years, and in 80% of Nilfisk repairs the problem was caused by poor filter maintenance.
