How fast does this rotate (how many revolutions per minute)?

I bought mine for my granddaughters for this Christmas. It has one 'on-off' button on the side and it has never rotated. It only lights up in the middle which is very pretty, but it does not rotate. Maybe I was sent the wrong model?

It does rotate and it comes with an adapter. There is a switch that makes it rotate or keep it stationary.

It does not rotate in a full circle.It vibrates and it kind of goes left and right very fast. It works similar to the original sonic tooth brushes.

I do not count its round per min, however it has the same speed whether you put load on it or not. It is a pretty strong motor. Its speed is around a normal robot you used to see on the YouTube videos. It's not too slow, but certainly not fast. I have not try to detach the wheel, since it looked like it is pretty well glued. But I think you can detach it by force!!!

The motor speed depends on the frequency. It is 940 rpm at 60HZ. if you bought recently, it could be 1450 rpm at 60HZ. The drum rpm should be 135- 140 rpm.

Hi mark. Without knowing " how fast is enough" for what you are doing, I would hazard a guess that there is a problem with your grinder. They should have a max rotation of about 10,000 rpm max.

I needed to send this one back. The first time I used it it didn't work. It ran at first and quit shortly after I began mixing. Since I used it with the outlet near the sink I did a test and no change. I tried it in different outlets but that didn't make a difference. Not sure of the speed, sorry.

The face spins continuously making a revolution in about 10 seconds. Love it!

Just timed mine, with almost new batteries (don't know if that matters). and at the fastest speed it take about 41 sec. for a 360 rotation. At the slowest speed (as it is completely variable) it takes 1 min and 46 sec. Used a stopwatch with a Nikon D800 camera and a heavy (14-24mm) Nikon Lens. Hope this helps.

It should rotate automatically. When both of the ones I had quit turning, there was not an option to get it going again.

It's pretty slow. Not sure exact numbers, but probably 10 Revolutions Per Minute. I thought I wanted faster, but once a couple of the lights were hitting it right, 10rpm was just fine.

I don't know how fast but it is pretty quick for having smooth tires, but I personally would buy a set of tires with a little tread, it spins tires alot without it

Standard rotation left to right as well as up and down. The unit is not frozen in one position

I believe three speeds of vibration with rotation. I am an Esthetician and I love this system for cleansing!

It turns back and forth. It does not make complete revolutions. Remove the head and bush up on the bottom brush and you will see how far the top round brush turns back and forth.

I've never timed it to the minute. It seems like 10 mins. Hope this helps :) I bought it over a year ago and still using it!

It is well balanced and cranks easily. You tyrn it at one revolution per second, so it's a slow turn. I am 75 years old. If i can do it, anyone can.
