Had it been mains powered I would have said give it at least a fortnight in the airing cupboard with the filters, dust container, etc. removed. The lower voltage of cordless appliances mean there is less potential for moisture-caused short circuits, motor damage, etc. The trouble with something like a vacuum cleaner is water drawn into the motor and then it is immediately switched off, the interior of the vac becomes an enclosed space. Placing the unit somewhere warm could evaporate the water but because there is little or no throughput of air that trapped moist air simply condenses into air and water droplets when the warmth is removed and overall improvement is minimal. You could fit the battery and switch on now and there probably would be no damage but if it was mine I would partially dismantle it and give it another couple of days somewhere warm...

Warm air is normal! If very hot so its able to burn your skin then that is not normal!

With portable tools, domestic appliances, etc. the power cord is the first thing to suspect as internal breaks in the conductors are not unusual (usually occurring close to one end or the other). The next thing to suspect is the switch...

I really love this vacuum. I have been using it since my kids were born. It's very good especially in my family where I have two severely allergic kids. I still remember how scared I was when my first born had this crazy anaphylactic reaction and he couldn't breathe. We rushed him to the hospital where they gave him a shot of epinephrine. After that we made an appointment with a child allergist. After an initial examination he agreed that it looked like allergies rather then asthma so he collected some blood and sent it to a private lab (You can check them here: https://www.intolerancelab.co.uk/intolerance-2 ) About a week later they called us in and told us that our son was allergic. It has been a struggle to keep him from ever experience something like that again because he's a kid and wants to explore. But we managed. And this vacuum has been very helpful too.

Switch or cord. Call hoover to get it replaced under warranty

I have never seen a reset button fitted to a vacuum cleaner - mostly the safety device is either a self resetting bimetal breaker or a thermal fuse. Likely failed to start due to a coincidental failure. Sometimes dust and fibres can work their way into the bimetal breaker but mostly it is an internal break in the power cord or a faulty switch. The circuit must be checked with a trusty multimeter and that will require the appliance to be at least partially dismantled.

Have a close look at the head itself, sometimes some debris can get caught in the opening behind the brush. Hard to see, but it only takes some thing like a matchstick size object to become lodged in there and collect a bit of paper or something... Regards Geoff

Possibly dirty filter
