Big improvement over prior generations, could be what you're looking for.
So, robot is going to robot, right? Various idiosyncrasies involved with this. First of all, the refurb is working great. No discernible issues with that status. But more or less issues with robotic vacuums.
First though, the positives:
1. Much smarter than roombas of yore. With app integration, you can have it map out a home, and tell it to intelligently focus on specific areas. I told it to clean the living room yesterday and it went straight there to clean up Christmas tree needles.
2. App is pretty good. Robot is scary good at mapping out your home and providing a user editable/label-able map you can use/reference going forward.
3. Base vacuum - when it works - is a great feature so you don't have to incessantly empty the bin from the robot directly
Negatives:
1. Legacy robot vacuuming annoyances. Robot *still* needs to stumble around in a grid fashion, bump into things, is loud, and can get easily clogged requiring intervention.
2. You need to keep a dedicated floor docking area clear for the robot's ingress/outgress. This is easier said than done, when other vacuums are shoved in closets or mounted on walls.
3. Clogs, clogs, clogs. Both robot and the base are susceptible to clogs that require human intervention. I'd really appreciate more Dyson-like engineering which makes it super easy and tool-less to empty common trouble areas.
4. Consumable parts are not cheap, whether just the base debris bags, replacement brushes, or filters. I wish it didn't feel like a racket. Cheaper 3P options are proliferating, but they aren't as good, and frankly Roomba seems to engineer against 3P options (e.g. bags).
Anyway, this generation of robot is leaps and bounds better than the last time you checked into this (likely pre 2012). They are still loud and clog often, but clean better and more intelligently. At the end of the day, if you have a good manual vacuum, it's still way more efficient to just vacuum a room and be done with it. But if you like the idea of scheduling cleanings, or you want to maintain a property remotely, or you absolutely hate vacuuming, this is an interesting option.
