Earlier quoted context omitted.
I move my vacuum robot up and down stairs as needed. I'm not _quite_ lazy enough to buy a second one for upstairs (but I _have_ considered it, I use an inexpensive Chinese knockoff, not a brand-name-priced Roomba...)
Are the Chinese knock-offs any good? I just looked up the price of a Roomba. $600 AUD to start for the shittiest model :(
