I would not get it
It depends on what is important to you but I would not get it for a couple of reasons. First, it's bagless, I'm not sure if it actually has a dirt bin that you empty or if all of the dirt goes in to the cone filter, but as stated above, it can lose airflow quickly, very typical problem with bagless vacuums. The other reason I would not get it is the hose end is nonstandard, at least on current models. Depending on how old this one is, that may or may not be the case, but if it is, you will be limited in what attachments you can use.
