So the bots had lots of advantages, thresholds tight spaces to navigate. This is only one of the trickier surroundings to get a bot to navigate smoothly.
For the first two or three sessions, we carefully tracked each bot, imagining its nav style and obstacle-detection and hazard-escaping customs. (To save time, we ran some bots concurrently at this stage–yes, it is interesting to see robots bash into each other.) We also looked at how complete the bin was at the conclusion of each cycle and made a note of this overriding sort of debris. Some robots came back with mainly full bins when the floor looked clean. See more vacuum your floor here.
Others started to come back mostly empty after a few days of intense testing. When the spiders did well from the first couple of sessions, we conducted them around a dozen times, experimentation with different dock positions, cleaning modes, and the number and severity of hazards we abandoned on the ground. (We had to use ground coffee in this evaluation too, but we did not learn much from that because all of them do well with it, so we cut that area.) Watching the robots address these hurdles gave us a much clearer idea of how each handled particular barriers that are known to cause problem for some robots, and it also gave us an obvious visual of how well each handled difficult debris. In our testing and research, the Deebot N79 was the most likely to complete a cleaning cycle on its own without becoming stuck and waiting to get a human to save it.
That is the most important part of a robot vacuum’s job, and the N79 does it better than almost any other version we’ve seen, even those that cost hundreds more. It is also one of the most affordable robots which it is possible to control from a smartphone, which provides you the flexibility to start a cycle as you’re away from home. And it’s tied to the quietest robot we have tested. It’s not an especially strong cleaner, also its own semi-random navigation system can miss stains of floor in bigger homes. But the two-hour battery life (among the longest we’ve seen) will help to offset those limitations through sheer persistence.
If you live in a home with a tiled floor program or you’ve got a great deal of plush carpeting and a few long-haired pets, then you are going to need something smarter or stronger than that. But for many houses, the Deebot N79 is good enough to keep the floors tidy if operate a few times per week.
The navigation system is the quality which produces the Deebot N79 great. Of any vacuum we’ve tested at any given price, it’s the least likely to get stuck mid-session on common hazards and obstacles. And after years of experience, we’ve found that the most important trait a bot can have is to just keep driving. Consider it this way: If you schedule your bot to wash while you are in the office and it has stuck on carpeting fringe 10 minutes into the cleaning cycle, then your flooring will still be dirty once you get home.
