ECOVACS DEEBOT N79S Robotic Vacuum Cleaner with Max Power Suction, Upto 110 Min Runtime, Hard Floors and Carpets, Works with Alexa, App Controls, Self-Charging, Quiet
Best for
Best for homes with mostly hard floors and low-pile rugs where someone is willing to tidy up cords and small objects before each run, and can accept periodic manual rescues; skip it if you want true set-it-and-forget-it automation or have thick, high-pile carpets that confuse its sensors.
What buyers say
Most owners agree the N79S pulls up a surprising amount of dust, pet hair, and debris from hard floors and low-pile carpets with minimal daily effort. The trade-off is that its random navigation often leads to getting stuck, requiring you to clear floors of small obstacles and sometimes rescue the robot or place it back on its dock.
Loved by buyers
- •It uncovers hidden dirt and pet hair in hard-to-reach spots, often filling its bin even after a regular vacuuming session.
- •Runtime of 90–120 minutes covers several rooms on a single charge, with quiet operation that does not disturb pets or daily life.
- •Straightforward app and voice control setup takes minutes, and consumables are cheap to replace when needed.
Buyer concerns
- •The robot frequently traps itself on everyday items like phone cords, socks, and rug fringe, turning scheduled cleanings into rescue missions.
- •Its bump-and-go navigation wastes battery life circling open areas or retracing the same spots without ever forming a memory of the room.
- •The exposed IR sensor lens is easily scratched from routine bumps, causing it to slowly go blind until it cannot find the dock or avoid walls.
Frequently Asked Questions
Does the DEEBOT N79S handle pet hair well?+
Yes, owners with cats and dogs report it picks up a lot of hair daily, often filling the bin even when floors look clean. The main brush may need weekly cleaning if you have long hair or heavy shedding.
How noisy is it?+
It is notably quiet for a robot vacuum. Multiple owners noted their dogs ignored it, and it did not disrupt conversation or TV, producing a low hum rather than a loud roar.
Can it clean thick carpets?+
It works best on hard floors and low-pile rugs. On high-pile or shag carpets, it may struggle with navigation and suction, and tassels or loose fibers can tangle the brush.
How tall is it? Will it fit under my couch?+
The N79S stands 3.1 inches tall. It slides under most furniture with more clearance than that, but many couches sit lower, so you may need risers to clean underneath.
Does it return to the charger by itself?+
It has auto-return charging, but in practice it does not always find the dock, especially if the base is in a tight space or it gets confused. Many owners occasionally have to place it back manually.
