I only know the Roomba. I have 4, lol. My first one 7yrs ago was from a thrift store. Then picked one up at Costco to have one upstairs and downstairs. Then picked up another at a yard sale for 20$. I have them set to run while we are at work monday wed friday. We have hardwood floors and they do a great job and fill their bins just about every run and now only use the central vac about once a month. They can be fussy but i am very handy and have taken them apart a few times, even the gear box. (not that difficult) ...then picked up a spare on e-bay for about the cost of a new battery. So three are all the same model. I've only purchased two replacement batteries in all this time. The main complaints i see are those that have way too much junk on their floors. Dirty clothing and such. And they will get stuck on rug fringe. They shut themselves off when stuck on something...usually a shoelace. No different than picking up for a regular vac. They are not for everyone nor do they replace your vac with much better suction, but after a long day at work, no-can-do listen to a vac or physically feel like running one. Gave one to parents and in-laws a few years ago. My dad runs his almost daily in their bedroom for his allergies. Had to show him all the quick cleaning tips. The first error codes seem to frustrate so many and why they are showing up at thrifts and cheap on ebay. (fine with me!) I enjoy taking things apart and studying. They do get lost on occasion and have to go look for them, but make it back to re-charge 9 out of ten times and will lock itself in the bathroom...one starts off in the bedroom, the other in the liv rm. They seem to meet up in the kitchen for a bit, then off on their merry ways. (DH's office is off limits, as it is aways a mess and door shut) We no longer have dust bunnies as they take care of it before they have a chance to form.

I have a Neato. His name is Rocky. This is my second Neato -- the first one gave up the ghost after about a year and a half which was disheartening. I have 2 dogs (one is a fur exploding shepherd mix) and 2 hairy cats. We run ours daily while we dog walk, and I'll say it replaces 80% of the need to vacuum. Maybe my cleaning standards are low, lol. Mine has no wifi and I don't use the scheduling feature; I just push the start button and let him go. The Good: The front corners and the little side brush are effective at getting into corners and running along the baseboards. The dirt hopper is large and it STILL gets filled each time I run it. I got the pet model with a rotating brush and it is very good at getting pet hair on both rugs and hard floors. It sits low to the ground and can get under pretty low clearances The Bad: He does get stuck a fair amount. We live in an old house and have black floor grates for our furnace...these tend to trip him up. He also gets tangled on long rug fringe, but not short fringe. He's temperamental and we have had to reboot him and calibrate the battery a couple of times. Overall, I wish he was less finicky but I can't imagine life without him. House cleaning is my least favorite chore and he makes a world of difference. I expect the robots will keep improving over time, and I fully expect to replace mine with another when this one goes. I'm hoping someone invents a dusting robot too.

I’d like to purchase one of these. Since my back surgery and hip surgeries, mopping the floor is difficult for me. We have all hardwood floors. Do any of you have any experience with these and could provide some advise?

There have been several posts about robotic vacuums. Here are the results I found. Personally, I've used them for years and prefer the Roomba. I'm not convinced that the rubber rollers on the newer Roomba do as good a job as the brush rollers on carpet. I tend to use my older Roomba (brush rollers) on the carpet, but it doesn't have the suction power of the newer Roomba.
