Query: Medicore Performance with a Design Flop

I bought this unit. It has a medicore performance. However there's a design flop with the unit (wonder why Bissell sells a lot of remanufactured?). The clean water unit will tilt toward you when you engage the paddle to start the vacumming (the clean water unit is attached on the handle of the vacuum so when you engage the unit to start to vacuum, the handle will not stand 90 degree anymore and so does the clean water unit). When the clean water unit tilt toward you, the unit will not spray the cleaning solution. This is easily to fix such by putting the velcro/wire so the clean water unit will not tilt toward you when you engage the paddle to start vacuuming. But I am surprised a big company such as Bissell will create such a design flop. I have not decided whether I am going to keep this machine or not due to the design flop.If they remanufacture these, they should have put the solution to their design flop unless they just too shy to admitt it.
