1- I have no idea why thickness is what you see this for. It's thin enough to fit under a coffee table, but not under furniture. 2- This Roomba is probably great if you don't have pets. I was advised to name it (you can name your Roomba btw) after something you don't like as it can be expensive to maintain and a bit disappointing at times. So I named mine Mitch McConnell because his sole purpose is to suck. Roomba Mitch McConnell does it literally and figuratively. Several times a week I watched Mitch walk over bare pet hair. it also gets quite constipated. Initially I was very excited to receive trip reports and a happy tone as Mitch McConnell successfully completed the job. But soon these trips were no longer successful without any intervention. Roomba Mitch McConnell (RMM) documentation says it should last around 2 months without needing to replace any parts (which to be honest seems quite an exaggeration). In less than 5 weeks I had to take it apart 3 times. Like the real Mitch, he bounces from one broken promise to the next. In just one month, I was taught to understand that I would probably need to interact with RMM at least twice as often as I thought to prevent his actions from negatively impacting my personal life. I often have to step in at least once or twice when Mitch (Roomba) takes over a task. So far, this is slightly less than human Mitch. but Roomba Mitch McConnell is just getting started. Roomba Mitch also doesn't seem to have the accuracy to destroy its namesake's mid-range by roaming the house in an unpredictable pattern. Will it drive right through the living room floor? May be. Won't it get stuck on a small leg of an exercise bike and send out a warning that it's on a cliff? Absolutely. Despite its shortcomings, I'd say the Roomba adds value to my life and manages to do at least some of the jobs a vacuum is supposed to do - it just doesn't act entirely on my behalf, but rather on its own proprietary, erratic. Mood. However, if you have a pet-free environment, I believe this Roomba can meet your needs - just as there is probably a more suitable environment for human Mitch McConnell than the United States Senate, where his actions have fewer consequences on human life or Wealth. of our nation - for example as a greeter in a civil war museum. try another option. But who knows? In the right environment, you might even find that you could enjoy it. Rumba. Not minority leader in the Senate.
