I have used it to clean under my sisters bed that is not much higher than the Turbopower 2's body and it did just fine, of course the Sebo will, it is as thin as a piece of paper.
I have found the performance of the Sebo to be no better than the Turbopower 2 despite the stronger suction on the Sebo, no it doesn't clean hard floors well but neither does the Sebo really, fine dust yes as it has that squeegee to stop "spit back" but bigger particles, no, it just pushes the stuff around which means you would have to clean the mess up with the hose which would be near impossible with the Turbopower 2 as it's hose is no where near as convenient...
