Robot vacuums the pentacle of laziness
What do stars have to do with this? :)
************
Lots of items we use could fit that category.
I suspect that you have been victimized by your computer, tablet or phone's autocorrect feature which is the pinnacle of laziness.
We have never had a robot vacuum but my sister swears by hers. I am not sure how a glorified sweeper is capable of picking up a whole lot of dirt... but in my sister's case she has 3 dogs and is happy with the performance of hers. Unfortunately my wife has health problems that prevent her from dragging our upright up and down the stairs in our 3-story home or pushing it across all of our old shag carpet; that is my job.
We have a giant 20 pound fluffy fur ball Siberian cat running around the house who is constantly shedding, so it takes an annoying amount of vacuuming to keep the carpets in this place clean. I am not sure that a robot vacuum would be able to help a lot; if they were not so expensive it might be tempting.
What the pinnacle of laziness is however people who do not keep their homes clean. But, I have to admit if my wife was not such a neatnick our house would be considerably more messy and dirty.
No, spell check is.
