They are both good machines. I have nothing bad to say about the competition.

The handle arrangement is different. Which you prefer may be personal preference. I hav eonly used the SX-12. I felt very comfortable using it in a baclk and forth motion like a vacuum cleaner. Some have said that SX-12 is easier to use back and forth and the Turbo is easier to swing side to side like a rotary machine. But not everyone agrees with that. Both machines can be used in either fashion.

The SX-12 has two vacuum tubes. I prefer this for better extraction compared to one tube on the Turbo.

Both machines have both type of floor rings, brush or hard plastic. The brush bottom should always be used when cleaning stone. A hard particle, even sand, tapped under the plastic ring could scratch many types of stone floors.

Aside from stone floors, a preference for brush or hard ring tends to depend on how much suction you have and how flat the floor is. The hard plastic rings can suck themselves down to a flat smooth floor. This is not likely to happen with the brush ring.

The machines work almost the same. The Turbo-Hybrid will leave the floor approx 20-30% dryer than the SX-12 (the recovery system inside the dome is different). The replacement parts for both of the units are comparable in price but the Turbo-hybrid parts are just a tad more expensive. I have used every spinner made except the WP one and all of them have their advantages and disadvantages. It all comes down to preference. I currently am using the Mytee one (got a helluva deal on it) and I am actually impressed with it. I like the gun grip and the ability to adjust the handle to different lengths. I am tall and on big jobs the "T" handle would hurt my back after a while.

I have used em all and Turbo Hybrid wins running away. It's lower profile, better construction, vac compensation valve, all make for a better tool. It has superior vac to the others hands down, doesn't matter that the 12 has 2 tubes, it does not have better recovery than the Turbo. I have 2 that I use daily. If you don't use it so often, buy the cheaper tool.

TurboForce is in the lead.

Maybe someone has another brad that they feel should be on the running.

I have only used the Turbo, mainly because of all the good things I read on this site!

Used both, own a Turbo and use it EVERY DAY.......hands down a great tool.

Turbo for me also...

I have the SX-12 and SX-7... I like them both. Never used any other ones.
