Thanks for your review, however, I think you've been a bit harsh on the product!
Although not as tough as it's predecessor, the bent tube on the GM200 - GM500 series, this particular bent tube was designed with ergonomics and comfort in mind, ahead of functionality.
However, the machine you have could be around ten years old, and for the part to give out, during more extream cleaning, rather than vacuuming floor and carpet, I don't think it's too bad!
Nevertheless, your review will help others decide if replacement of the part, or replacement of the machine is right for them!
Keep your reviews going!
Thanks, Andy :)
