I'm enjoying my new Mi Robot Vacuum, just received last week after a recent Ozbargain post. Performance has been great, my only problem is that I have 2 sofas that are just high enough for the vacuum to go under, but they will eventually get stuck. The virtual walls (magnetic strips) are the obvious solution, by my sofas are sitting on a rug. I have heard that the magnetic strips can work from beneath a rug - anyone had any experience with this? I guess the strip needs to be on the floor (ie can I affix the strip to the underside of the sofa?)
Update: I ended up using these rubber castors from Bunnings - they do the job and aren't too expensive. https://www.bunnings.com.au/castor-cup-square-tic-41mm-sq-br…
Try and find out if it works for you
Correct. and if it doesn't work under the rug, then put it on top of the rug, just under the sofa. It doesn't need to be stuck down.
