Breaking point on the purpose of buying new rubber hose!

After a few years to buy a new center because water hose was defective for oral irrigator!
When a new device, the battery is quickly empty, which is a disadvantage when driving on vacation. So I take old and new toothbrush from Braun with !!
Now again, although oral irrigator is hardly used, the tubing is broken for oral irrigator. Irrigator can be openable only by force, but not repair itself. Stopgap would: Insert tube in the nozzle! But that holds only a few days because of the hose at a different location is defective again and a further reduction is no longer possible!
Is this dumbing down of the customer, so he buys a new, yet kurzlebigeres device every few years?
Anyone who knows a better device or another solution!
