Although extremely easy to use as the Air Ram K9 is very light compared to other big name cleaners it is extremely flimsy. When receiving the vacuum I expressed concerns to my husband about how long it would last. 7 weeks down the line the pivot neck has jammed and I am unable to use this. The design is very poor. Gtech, after a number of emails have sent me a new part and assure me this will resolve the problem. Time will tell. It is clear from numerous threads on the internet this is a common problem. They also expect the customer to take apart the vacuum and remove the battery to install the new part. Truly shoddy service given they are aware of the issue. I seriously would advise anyone to think twice about purchasing one of these. Very disappointed.
