Our Amazon history includes ECOVACS DEEBOT N79S vacuums in July 2018 and April 2021. For years, it was one of the most appreciated devices in our house. With mostly hardwood floors, a shedding dog and two children, there was plenty for it to do. It ran frequently and took a recurring task off our hands. By August 2026, we had replaced it with a cheaper robot from another brand, but I still thought well of the work the N79S had done.
- Repeated purchasesN79S vacuums appear in our 2018 and 2021 order history.
- Keeping them goingReplacement batteries and a brush-and-filter kit were part of ownership.
- A different next purchaseBy August 2026, a cheaper model from another brand had taken over.
The job it earned its place doing
The N79S was good on our hard floors. My assessment of its carpet cleaning and pet-hair pickup was more qualified: okay. It had limits, including furniture and stairs, but the work it did on the floors was useful enough that we kept using it and eventually bought additional units.
I valued the repeated cleaning. A robot vacuum could get on with a boring household job while we did other things. In my August ownership notes, I described the time it saved as its best feature. In a house that needed regular cleaning, that was a meaningful contribution.
Learning what ownership involved
I found it fairly reliable, with a manageable amount of maintenance. Part of being satisfied with it was developing reasonable expectations: what it could clean, how long it would remain useful, and what maintenance could extend that useful life.
The battery was the wear item that stood out. Our records include compatible replacement batteries in 2021 and 2024, plus a brush-and-filter kit in 2021. We replaced batteries to keep machines going longer. That bought some additional use, although a replacement battery could only extend the life of a machine so far. Keeping it working was part of the ownership experience.
The features I actually used
I almost never used the app. I sometimes used the remote, and I did not use Alexa integration or voice commands. Those features were peripheral to the way the vacuum fitted into our house. Its value came from doing the floor cleaning, repeatedly, with relatively little attention from us.
Why my next purchase changed
In August 2026, I said the N79S had become more expensive and that we had moved to a cheaper model from a different brand. The replacement was doing the job well enough that I would not have bought another N79S at that point.
That buying decision came after years of useful service. Multiple purchases and replacement batteries reflected how much we had appreciated the older machines. For our household, the N79S had been good value, even though I eventually chose something else.

A useful appliance can still lose the next purchase
The change to a cheaper robot does not erase what the N79S did well in our house. It earned repeated use by taking a frequent, unappealing job off our hands. Replacement batteries and another purchase make sense within that history: I valued the cleaning enough to keep the machines working.
The next buying decision had a different comparison in front of it. By August 2026, another model was doing enough of that work at a lower cost. That is why a long period of satisfaction and a decision to buy something else can sit in the same review. For me, the useful benchmark was the recurring floor-cleaning job, rather than an app feature I rarely used. This remains a dated household judgment, not a current comparison of robot-vacuum prices or performance.
