Not as young as I used to be.
I have a CMX-20, this is the slow speed model that has the power module.
The only way to get it up steps is to carry it.
It does a fantastic job, but I got a contract on (lets just say... a lot,) of two bedroom apartments, and all of these are on the second & third level.
Some are on the fourth.
No elevators in these units.
If I need a rotary, I want it to be easy to take upstairs, & lighter than the CMX-20.
Thanks
PS: Maximum length of hose is only 100-150', which is still easy for my LRV machine.
