A robot vacuum seems like a very frivolous purchase, until I ask you the question, "When did you last vacuum your house?"

You only need to spend a week with a robot vacuum doing scheduled passes on your floors to realize just how very necessary these smart home devices are- you'd be both amazed and disgusted at how quickly the waste bin fills up even when there is no visible contamination on your floors. This is how it goes when you don't have a robot vacuum- you look at the floor, you say "oh, it's not that dirty, I'll vacuum tomorrow", and this goes on for a few more days until you finally get around to it. Meanwhile, if you'd had the robot vacuum on scheduled cleanings, you would've emptied a full waste bin 3 times already chocked full of crumbs, hair, dead skin cells, and more, without even knowing that your floor was really dirty.

The best part of it all, is they don't cost an arm and a leg anymore. Sure, you can spend that much if you wish, but I got my Shark S87 used on LetGo for about $150. That, and all of the consumables are easily user-replaceable on this model. A kit of spare sweeper-arms, rollers, etc. can be found for about $20 on amazon.

The wandvac costs about $100 alone and is very handy for a quick once-over of any corners the robot didn't quite reach, or any surfaces that are up higher in your home, such as the couch cushions. This is the complete home cleaning set and I recommend it to everyone, until the next generation of robots with more advanced features reach similar price points for used examples.
