Faulty Bosch vacuum cleaner (SW2 - Brixton)

Please read !

This vacuum cleaner is faulty, sometimes it works and sometimes it just goes dead. If you give it a thump it sometimes comes back to life, but sometimes not !

Perhaps it has a loose connection inside, so I’m looking for someone who is good at fixing electrical items that can take it and hopefully fix it and keep it going

It comes with 4 x new Bosch vacuum bags too

Thanks for looking :-)
