Can you tell from just looking at this when it is/when it is NOT vacuum'ed?

No, you can't tell by looking at it. However there is an audible clicking noise when the air is out of the bottle, so that's how you can tell the air is vacuumed out. The point of it becoming harder to pump varies based on the amount of wine/air left in the bottle. It isn't difficult, though, just provides a bit more resistance.

No. It clicks when it's vacuumed. I like to pump it a couple more times/clicks. THis clicking is a new-ish thing. My 20 year old VacuVin I just pump til it resists. I feel like the new one doesn't pump enough out, but what do I know? I never have the wine sitting around for more than another day or 2, so just a cork would probably be enough to hold most wines.

It's very easy to pump when you start. After about 5 seconds you can't hardly pump it because all air is out.

There is no visual evidence but you hear an audible "click-click" when air is removed. When I pull the stopper it makes a hissing sound like opening a fresh can of soda

No it's open. It's so you can change the light bulb easily. We just stick the vaccume hose in the open area to clean.

Yes. The frequency depends on hours of use and how much dust and dirt is in the air. Inspect it and if it is dirty replace it.

Yes, it has turned off/on. Look down at left side of the canister with big red button (Brush Roll). Check Quick Guide book.

It depends on your specific situation. You should check it at least every six months for excess dirt. Have a professional do it if you are not capable of checking it yourself. Mine lasts about a year with light use in a small house.

This vacuum is at another location and I would have to look at it again. Sorry I couldn't help!

It has been running as long as I vacuumWhich is maybe 30 minutes or so.It has never run out yet.

No. I have been running it for almost 2 years. Cleaning it a few times year, it still seems to hold up great.

There is a groove on the inside. It wasn't really problematic when cleaning it except that I had pay a little more attention to it.

Hmm? Im not sure? I have had mine for about 6 months, and so far, its been the best vacuum i have ever owned...good luck to u:)

The first thing I would do is check to see if the bag is full. Secondly I would check to see if anything was clogging the hoseAnd if neither of those work I would take the vacuum to a place where they repair Mieles for a complete check up.

You aren't supposed to look directly into it. Plus, you only use it for a limited time- I only use it for 15 minutes at a time. So, it really isn't much of an issue for me.

You will know it is dirty when you notice demolished airflow from the vents. As a rule of thumb, I clean mine once a month.

If you make a point to smell it, it still has that odor. But I don't notice it on a daily basis, nor do I notice it when I'm handling it for use. I bought mine in August to give you a sense of the wear on it. The odor has dissipated a little since I bought it, so I assume it will continue doing so over time.

I believe it's glued on. you could vacuum it with a hand tool, use a lint roller or wipe with a lint mitt.

I can't say for certain if its a closed system or not, but I haven't seen/ noticed dirty air. This is a great vacuum.

no unless you use the ohm meter function to check continuity. That could tell you if it's open or not.
