Thank you for all of your replies. This really helps. Thanks!

If I'm in the room I leave it on, but if I'm going to leave the room I turn everything off, because I am prone to being distracted and before I know it, it'll get left on all night.

I have my sewing machine, lights, and iron all on switches that are controlled by my Alexa. I can turn things on and off individually with my voice, and I have grouped all of them together in a group named "Everything" - so when I'm leaving the room I can just say, "Alexa, turn off everything" and the whole room gets shut down. I love it, it's so "Star Trekky".

I don't unplug my machine, but I have it on an expensive surge protector AND a UPS ("uninterruptible power supply" - basically a battery back-up and power "cleaner") so it is very unlikely my machine would get hit by surge. I want to get a whole-house surge protector added at the box; I hear they are not very expensive and I like as many layers of insurance as I can get!

A sewing machine repairman told our guild of a computerized machine left unplugged on a serge protector that blew the serge protector and the sewing machine during a lightning storm. I leave my machine on when I am making something, but always unplug it at night or if there is a thunder storm coming.

My machine is a Janome MC 14000 that can be set to power down after a specified number of minutes has passed without activity, so I wouldn't need to turn it off for pressing or pinning, etc. However, I turn it off when I leave the studio.

Surge protectors are for different voltages. We got several very high voltage protectors. Put them on TV, PC, microwave, sewing machines. A tree fell on a line during a storm and fryed everything in the house; phones, clocks, micro, tv,etc.... The whole house surge protector would have made a difference.

Same with the ECO button

For those that unplug, do you unplug from the machine side or the wall side?

I will leave mine on while I do a quick press, but when I'm done for the day or a longer period of time I shut it off and unplug it because we have a lot of thunder and lightening storms here in Florida & I wouldn't be able to afford another nice machine like this one!

I leave mine on when I am working with it, sometimes leave on when I go up to make the munchkins lunch. Off at night. I do unplug iron every time I step away...heard all the rowenta stories! I wonder, does the machine "count" the time it is on or the actual sewing time?

I leave mine on for hours at a time, even when I know I won't be back for maybe an hour or more. Doesn't seem to hurt it but of course the machine has one of those "machine hours" so its not really exact in how many hours I'm on it but I don't care that much about that.

I turn mine off--don't like to because I have to change the stitch length and any other settings that I have changed. Don't have a eco mode.
