I jus received the E20 model and started to try it out. It works well. But then I downloaded the phone app for android and found out the vacuum can only communicate with the phone using 2.4g wi-fi, but my wi-fi router/gateway only uses 5g, so I cannot use all the functions to control the vacuum from either of my phones.
This forces me to return the vacuum.
I would like to know of another model comparable in price and function to the E20 but that can use a 5g wi-fi signal, but am having trouble finding it in any advertised listing.
I like the vacuum, but since the E20 can only communicate using 2.4g which is outdated, the vacuum is useless to me without access to all the functions.
So again, which models can also use 5g wi-fi?
