Dyson hand held series:
If you live in a one bed room or smaller, then it’s ok. Or if you are planning to do a bit of vacuum everyday, then it might be ok. The thing is it only lasts about 15 to 20 minutes, or just enough time to clean one room. Then it would take hours to charge. It cannot operate while plugged in. If you plan to clean just once a week, and want to clean more than 1 room with your free time, then don’t get Dyson. I have one, and I like it’s cleaning performance, but I just don’t have the energy to clean everyday.
Most of them can self-charge which is great. I don’t think the stressing out the pets criticism is all that valid because my Dyson V8 scares the crap out of my cats anyway. If a robotic vacuum runs around all day, the cats probably will get use to it sooner.
My only issue with robotic vacuums is that… they still cannot recognize poop… or puke.
If you have pets, then occasionally they would have stomach issues and poop ends up on the floor. That’s already pretty bad, but not as bad as a robot vacuum dragging it to cover your entire floor with it. The same goes with puke.
