I’m really disappointed with my new Roomba

Mine isn't a high-power sucker if that is what you are looking for, but it does the job. I do real vacuum the carpets every week or three to get what Roomba leaves behind.

I have one short-haired dog that sheds A LOT and a cat that also sheds plus I live near a field with crops or cows depending on the time of year which means dust is a factor.

Every once in a while Roomba will leave something behind, but not usually.

Run time for my Roomba is about 1.5 hours before it heads back to base to charge

ETA:  Roomba runs on my hardwood and a 8x10 rug
I don't think it works well on thick carpet

Worst money we ever spent. And my husband wanted to return it, but I wouldn’t let him, so I have to pretend it wasn’t the worst money we ever spent.

But it definitely was.

Hated ours. It required too much babysitting. It’s easier just to do it myself.

I love my Roomba - in fact I have 3 robot vacuums.

That said - they are not regular vacuums and really can’t compare to or replace a regular vacuum.

Mine are used to keep the dog fur under control and to keep the general dirt/dust off the floor. I still vacuum with my dyson stick quite often.

After singing its praises for months, it's kind of pissed me off lately. It keeps dying and forgetting to go dock and recharge or saying it's full when it's not and requires a special wipedown.

It's still great for between vacuums, with 3 cats and a dog, but it hasn't lasted nearly as long as it should have and I think they're too finicky. I do love seeing those fresh vacuum lines in the carpet in the morning.

Not sure if it counts but we have a Shark IQ which is a roomba knockoff. It has a canister so when it’s full it can dock, unload and keep going. It can also ‘memorize’ the room layout so it makes sure to get everything. With 2 cats it saved us when the pandemic started. That said, we have since got a Dyson v11 and it is amazing.

Do you happen to have a shark navigator?  I had one and the brush roller stopped working. Shark really pissed me off when I tried to get it fixed - they told me I needed a part that wasn't under warranty so I purchased that and it didn't work; then they charged me shipping to return it and finally sent the part that was under warranty.  So if it is your brush roller than has stopped, let me know and I'll go pull the emails I have and let you know what you need to do/say to get that fixed.

I received one as a birthday gift.  I had never hinted at wanting one, so I have no idea why he bought it.  I have a really good vacuum and I actually like vacuuming.  

The thing was always getting stuck somewhere under couches or chair legs and I had to keep rescuing it.  If I had been out of a room for too long, I had to hunt for the darned thing because it was no longer making a noise.  It did pick up from the areas that it travelled in, but it was too frustrating to run because you had to sit and babysit it.

This version was years ago, so maybe they have improved them since I had mine.  It ended up not working after a couple of months.  They sent me a firmware update that I had to install and return to them.  It didn't fix it.  I tried a couple of times to get it fixed and the support wasn't very helpful.  I ended up just tossing it.  I probably should have persevered, but I was annoyed that it was taking so much more effort than whipping out my vacuum did.

we had the same experience. The clock could not keep itself straight, it was loud, and it would get stuck somewhere every single time.  Not worth the hassle.

I like ours, but our dog does not and I don't use it as often as I had planned because of that. I have to pick up/sweep all the small pieces she creates with her bones or paper before I can run it. I do like it instead of the vacuum. Ours is in a location that gets bumped and I don't keep up with checking the charge.

DH was the one who just had to have one, which I never understood since I doubt the man has run a vacuum on anything other that his truck interior in over 25 years. I think if you have multiple pets that shed it’s not going to do much for you. We got ours when we had three shedding dogs and it was a joke. It doesn’t get into corners, it fills up really fast, it gets stuck under the same couch every single time so we had to block off whole sections of the room to keep that from happening. Plus it’s noisy as hell constantly thunking around into walls and doors and chair legs so I never liked running it when I was home, but if I would run it when I was gone it would always get lost and I’d have to go on a search and rescue to find it.
