The only complaints that I have are:
1) I have mine set to notify me when it's done cleaning. Sometimes it will do it immediately after it's done, while other times the notification might come two or three hours after the fact. Still other times, not at all.
2) I have to clean the vacuum more frequently than I would like. That means: cutting out hairs from the "side brush" on the front of it, cutting hairs out of the "main brush" that sucks up most of the debris, and wiping the sensors clean. In fairness, I'd probably have to do the same sorts of thing with the rollers on a normal vacuum cleaner after a while too, though.
3) There's been a handful of times over a 2-ish year period where it'll go to the other room to start cleaning, and while a normal trip might take 15-20 minutes, it'll claim to be done in about 5 minutes. I suspect that blankets may have fallen on the ground or something, so it became too "blocked" to be able to clean properly, but it could be some kind of software error.
Check your mobile's app settings/battery optimisation? Sounds like the app doesn't keep running properly in the background
Exactly. We changed from some fancy one that my boss gave me to a cheap one that you operate with an old-school (can't believe I'm saying that) infrared remote. It doesn't "think". It just works like our other reliable dumb machines - diswasher and washing machine. We don't own a regular vacuum cleaner as I just do a regular sweep with a broom when we want a thorough job done.
All other home tech gadgets friends and family have acquired live in limbo land stored in the back of the draw or on top of the cupboard, never opened or tried once but got stuck downloading some stupid app. But we can't just throw it away yet, as there's guilt around acquiring that smart tech thing in the first place even though we know there's already so much e-waste.
