I purchased the D7 in March and just last week it stopped working (the laser just wouldn’t work) mid cleaning. Luckily I have an older Neato that has been demoted to the basement so we can still get the daily vacuum. But I will say I run the D7 everyday on turbo mode and while it is louder it picks up all the hair and everyday mess that goes on in a home with 5 kids and a dog. I love the no-go lines and honestly if it weren’t for it crapping out mid cleaning I would easily give it a 5 star but for receiving it 3/28/18 it’s a little soon to be having issues. They were great about getting it in to get it fixed and I can’t wait to have it back.
