why does it go off after just a few minutes of use?

Hmm.. unsure .. ours goes for a while - we leave it charging when not in use, so it's always ready to use, and goes a fair length of time for us to clean up a250 square ft space rather well before starting to sound like it may be dying out. It's also a couple of years old, so I suspect the rechargeable battery is aging. Maybe you got a lemon?

Mine does not go off after a few minutes. As long as it is charged, it will do pretty good. I've never ran it till it died, usually use it for quick spills and what not and it does great

Short battery charge life. Shark customer service (if you can call it that) is terrible. Their replacement parts are so expensive, that it's not worth it. I would never purchase another Shark product.

I have a different model shark. After having similar problems with a short battery charge life, I researched online. Apparently many people have experienced short charge lengths. I still have mine because when it works it works fine. If allowed to charge a long time, charge will last longer.

No, its set for a certain amt of minutes and turns off after time runs out.

It should continue the cycle after a few mins. I'd contact the manufacturer to clarify.

As I can recall....it's been a while since I had it...it goes off for quite some time. BUT...you pretty much have to be within a few feet of it to hear it going off. That's why I sent it back.

Yes it does stay on for just a short period of time but not more then a few seconds.

It shuts off after a minute of beeping and then counts forward. Sometimes this is nice because I'll be called away to do something after I've set it and can come back and see that it's gone off and then counted up to 2 minutes or whatnot, and know that it went off 3 minutes previously.

It beeps for about 1 second then the spray goes off. It all happens in less than 5 seconds.

It eventually goes off, but not immediately. It's always still on when I leave the kitchen, but not on the next time I enter the room.

I'm sorry but ours doesn't do that at all. It works perfectly and only comes on as needed to get the room to temperature. I've never noticed it coming on for 2 seconds or less and going off, etc.

There is an auto off feature. You probably accidentally activated this feature.

I can say this it will shut off after a few minutes or so.Any otherissue's I would call the company thy worked good with me!

Not that I've ever noticed. It automatically turns off after a minute or two, so there really isn't enough time to "warm up" even if it might have done it with more time.

Yes, ours did that as well. You get used to turning it off a few seconds before you want it to stop!

It has a timer. It'll only run for that set amount of time then it'll turn off. That's normal.

Haven't had it long but the monitor goes off after a few minutes when running on battery.

It goes off for about a minute, then shuts off. Best timer I've ever had and I've had lots of them.

Hard to say without seeing it. Double check your wiring and your settings. It could be a loose wire, for example, or maybe the sensitivity is turned up too high. I set up the sensitivity on mine to come on right as you walk through the door. Also, if you have the time turned all the way down (test position), it will stay on for like 30 seconds and then shut off. That's the shortest setting. If it's coming on and off in shorter intervals than that, there is likely an issue with how it was connected.
