If the machine switches on and off in quick succession, while making a pulsing noise, it could be an indication to either a dirty/blocked filter or an obstruction in the machine affecting the airflow.
Dirty filter
To maintain optimal performance, the machine’s filter(s) should be washed regularly. Instructions on the filter maintenance, including a step-by-step guide, can be found on our ‘Cleaning the filter(s) on your Cordless vacuum cleaner’ article
Airways obstruction
In the event of an airways obstruction the machine is designed to pulsate. This is an audible feature that not just indicates a restriction of airflow, but also helps in preventing damage to the motor.
This is usually caused by a physical blockage in the machine, where debris has become tapped in one of the following locations.
- The Cleaner head/Accessory
- The Wand
- The Cyclone inlet
The easiest way to identify where this blockage is location, is to visually inspect each of these locations. Start by removing each component from the machine and inspecting it for trapped debris.
Be careful not to pull the power trigger while looking for blockages.
Make sure any blockages are clear and all parts are refitted before using your machine.
Further instruction on checking for a blockage, including a step-by-step guide, can be found through the below resource.
