Hi,
We are sorry to hear that you are not happy with your purchase.
This machine does have a runtime of up to 20 minutes, as stated on our website, this timeframe is calculated when using the machine as a handvac with the crevice tool attached, unfortunately, using the machine with the powerhead attached will lessen the runtime as this will require more charge to operate.
The main cause of dust and debris dropping out of the machine is a blockage, this can occur in the head, rod, canister and filters of the machine.
Maintenance instructions for the machine can be found on pages 11-13 of the user manual provided.
If you are still experiencing issues, we would recommend taking the machine and charger into your nearest store, with proof of purchase, for inspection and to discuss available options.
Regards,
The Godfreys Team
