I owned a Roomba in about 2007-2009, an early model with brushes. It died and was revived by dis-assembly and sensor-cleaning several times, but in late 2009 it died the final death.

Enter Roomba 880. I bought it because we were losing the battle against dog hair. I ran it for hours daily the first weekend, basically filling it and dumping it until the battery ran down (several hours) then recharging and rerunning. I would estimate that it took a solid 12 hours of vacuuming the upper level (hardwood & carpet) before it was not filling up within 30 minutes. I was gobsmacked at how much dirt AND hair it was finding and for how long.

Now it's scheduled to run every other morning. Never gets stuck, and it has never stopped for being full since I did a carefully managed first week of cleaning.

I also check the rollers, because long hair can get wound around them. Much less often than with old Roomba, but I want this thing to run forever.

Highly, highly, highly recommended. Especially if you have a shedding dog.

We had high expectations given the price and the 880 exceeded them.
We have two dogs and two cats. My wife was vacuuming
Daily to keep up with the hair but no longer is this the case.
We use the daily schedule and empty the unit daily.
We are amazed how well this unit works. Getting under furniture
And even cleaning the hair that clings onto the bottoms
Of the chair feet where hair tends to cling to the felt protectors.
We have hardwood floors with area rugs and the 880 negotiates all of the areas
With amazing results.
Thank you roomba.

The use of 880 when the room very clean?
