Many would say that you would have to buy another new vacuum cleaner which cost a bomb, BUT you must understand that if you do not trade-in your pro-aqua for a more established company like delphin who have been in this business for more than 12 years, you'll only lose it all when the machine...
1. Call other companies like Rainbow or Delphin. (preferably delphin)
2. Arrange for a demo. (it may sound funny, like a sales approach, but trust me)
3. Make use of the free cleaning and ask for as much discounts as possible
4. Show them your pro-aqua and say you have no use for it.
5. Request...
I am sincerely sorry for those who purchased the Pro-Aqua vacuum cleaner, because now your warranty isn't useful anymore. Any problems with your motor and that's it. Money down the drain. But I have a solution for everyone who share this problem.
