Landlord.
Why on earth would you put the Ace etc etc on the floor?
I put mine on a stand and empty through the tap, surely no one puts them on the floor.
My GF sits on a low trolley maybe 10cm off the floor and there is a hole in the center of the trolley so if I ever need to I can reach the element reset button.
the GF et al are supposed to be low down just take a look at the manufacturer's videos.
Of course if you have the height and can use a pulley it all changes and the location of the controls becomes a minor issue assuming they don't get them wet through when you're cleaning.
