No, it’s in case you get locked *in * your car, so you’re already in the car and can plug it in. 
Good point, try $99.
The Flobee will give you the best haircut you can get. But it requires a canister vacuum cleaner. My wife got rid of our canister vacuum soon after we got Flobee.
I failed to mention the Filter Queen she bought at great price from a door to door salesman. It had plugged up hoses endlessly and the belt had to be put on weekly.
My solution for to expensive to make ice cream was I threw the damn thing out. I purchase ice cream for way less, and I couldn’t ever make the Breyers Fried Ice cream stuff, or the Culvers good stuff. I don’t know why people are concerned that I won’t make ice cream ever again.
She really doesn’t have any sales resistance.
So, gonzo, how has this lack of sale resistance affected your marriage, if you don’t mind my asking?
My instinctual revulsion to behavior like the OP describes would not have allowed me to marry her in the first place. There’s NO WAY a tendency to behave like that would have remained hidden from me.
I pay no attention. She defends every purchase like she is saving money or providing an important service we did not know we needed.
It sounds like you are the right guy for her.
I used to have a wife who was unable to delay gratification. I got her to agree that we wouldn’t buy consumer items with a credit card, so if we wanted to buy something nice we had to save for it. Her inability to wait meant that we ended up with a house full of crap. We would pick out a nice table that might cost $1000, and three days later I’d come home to a delivery truck in the driveway unloading some crap teak-veneer-overprice-at-$350 POS. Same thing with TV’s, artwork - everything.
My dad moved from the family home to a small condo and had to give up some furniture and art that wouldn’t fit, and I realized at that moment that there wasn’t a single thing in my house that my kids would ever want if I died. Not a single heirloom.
After the divorse, I had the hugest garage sale and got rid of most of the things I owned. I made over $1000 and bought a coffee table and some lighting. I didn’t have real dining room furniture for almost two years, but I do now, plus a nice TV, computer, mattress ($1200, not $8K), etc. That garage sale was very theraputic.
What is it about a canister vacuum specifically that is required? I would’ve thought all you would need would be a vacuum with a hose. My upright has a hose. Would it not work?
Why is it that “upright” and “hose” that close together sounds dirty?
Hmmmm…
I think that I have too much sales resistance. I seem to have an inherent distrust of people trying to sell me stuff, so my knee jerk reaction is always “No, thanks!”. I could be on fire and still instinctively shoo away a fire extinguisher salesman. I don’t know where this comes from.
How’s about I go out shopping with your wife, and when a salesperson pops up, I’ll jump in between them and put all of my years of “No!” to good use. I’ll do this for the bargain rate of 10% of the price of purchases she would have otherwise made. Whaddya say? 
It says it needs a canister type. May be the volume of air required.
