Robotic vacuum cleaners have been around for more than a decade, so they’re not exactly the “latest” piece of technology. With each new model that hits the stores, we find ourselves becoming less in awe – high-pressure suction, Wi-Fi connectivity, multi-surface cleaning, and so on, and so on. We’re looking for something that’ll excite us!
Which is where the Deebot OZMO 920 Robotic Vacuum comes in. This disc-shaped little fella promises a ton of upgraded features which seem very promising.
But the thing that gets us excited the most is the OZMO technology that Ecovacs is oh-so-very-well-known for. Let’s check out what the OZMO 920 will pack and what sort of promises it hopes to fulfill.

OZMO Mopping Technology
OZMO has been one of the most recognized mopping technologies in robotic vacuum cleaners. Drawing water from a small built-in reservoir, the OZMO 920 can remove sticky residue from hard floors so you won’t have to mop after the vacuum finishes its cleaning cycle. This optional feature can be activated whenever you want.
Mops and Vacuums… Simultaneously!
Now, this is fairly new in the robotic vacuum game. In a single cleaning cycle, the OZMO 920 will mop a newly vacuumed floor in without users needing to switch between cleaning modes. It’s fair to assume that the simultaneous vacuum-and-mop feature will drain the robot’s battery quicker, but cleaning efficiency is definitely worth the tradeoff.
After all, the OZMO 920 is programmed with one of the most convenience-adding features ever, namely…
Auto-Recharge and Resume
Not a new feature at all, but it’s something that doesn’t get the love it so rightly deserves. Without lifting a finger or a smartphone, the OZMO 920 will make a beeline for its charging station upon receiving a low-battery alert.
Thanks to its new-and-improved navigations system, it will most likely be able to find its way without getting lost. After the battery has fully charged, the OZMO 920 will continue its cleaning cycle where it left off. The robot is self-reliant and waits on no one to get the job done!
Smart Navi 3.0
The OZMO 920 is packing Deebot’s latest navigations technology – Smart Navi 3.0. Released in late 2018, it’s not the latest feature to be implemented in Deebot robotic vacs, but it’s still worth noting.
The wide sensor on the OZMO 920 will continuously scan your floors in search of obstacles and create a virtual layout. Smart Navi 3.0 allows the robot to create the most efficient travel path across your floors while also avoiding collisions with whatever lay in its path. Best of all, Smart Navi 3.0 supports multi-floor mapping.
Improved Virtual Boundary
Virtual boundaries can be set via the ECOVACS Home App. This allows users to create no-go zones, forcing the robot to concentrate its cleaning within one or multiple rooms. The OZMO 920 uses an improved virtual boundary system which is programmable not just for vacuuming but also the OZMO mopping feature.
The older generation of robotic vacuum cleaners had difficulty distinguishing between hard floors and carpeting. The latter requires higher suction pressure to dislodge and remove debris from long fibers. The OZMO 920 is equipped with carpet sensors that detect which surface it’s currently on.
When waling on top of carpeting, the Ecovacs Deebot OZMO 920 will automatically increase suction power for a deeper clean.
Ecovacs Deebot OZMO 920 vs. Deebot 500
From their respective model numbers, we can safely presume that the OZMO 920 is a much newer model compared to the 500. But does newer mean better? Short answer: you bet it does. But let’s see what the 500 is packing anyways – you might be interested in the budget-friendlier option which is the Deebot 500.
|Ecovacs Deebot 500 Main Specs|
|Suction Power||1000 Pa|
|Сleaning Area||1292 ft2|
|Dust Container||520 ml|
|Battery Capacity||2600 mAH|
|Charging Time||240 min|
There is no mopping feature which is standard in older generation robots. This is not the end of the world by any means, and perhaps we should be thankful since old vacuum-mop combo-bots performed poorly in both areas.
As an older model, it won’t have many of the convenience-adding features that we know and love. For instance, the 500 does not have any version of Smart Navi. Its “primitive” sensors simply detect the presence of obstructions and cliffs to prevent robo-suicide. Also, there’s no virtual mapping system. Essentially, it’ll trek across your floors blindly in hopes of meeting dirt and crumbs to suction up.
The 500 is designed to run for 110 minutes straight – roughly the same amount of cleaning that the OZMO 930 offers. What’s missing is a resume feature to its auto-docking ability. It’ll recharge upon detecting a low battery, but you have it won’t get back to work. Commanding the robot to start vacuuming means beginning its cleaning cycle from the very beginning.
Now onto the positives. The 500, like the OZMO 930, is compatible with Amazon Alexa and Google Assistant. Users can also give commands and program cleaning schedules using the ECOVACS HOME App. These two things together make for an ultra-convenient robot that excels at cleaning hard floors.
Ecovacs Deebot OZMO 920 vs. Deebot 711
Now onto the Deebot 711 – a robotic vac that was released in the fourth quarter of last year. We have high expectations for this robot since it’s roughly only a year old. Technology doesn’t develop that quickly, does it?
Apparently, it does. In just a year’s time, ECOVACS have adapted Smart Navi 3.0 as the standard navigations system in their modern robots. The 711 is stuck with the outdated Smart Navi 2.0. From our and many customers’ experience, there really isn’t anything to complain about. It does a good enough job at creating digital maps and efficient paths so the robot won’t cover the same area twice, and most of the time it won’t leave residual dust after the first pass.
The main difference between the 711 and OZMO 930, other than the former’s lack of an optional mopping feature, is the ability to create virtual boundaries using the ECOVACS HOME App. And since the 711 isn’t compatible with virtual walls, there’s no way to limit or focus its coverage area.
Like most modern robots, the 711’s battery can supply up to 110 minutes of continuous cleaning before the robot needs to recharge. It’ll auto-dock on its own, but it won’t resume its last cleaning task afterward. You’ll either have to use the remote control, the smartphone app, or voice commands through Alexa or Assistant to tell the robot to get back to work.
In terms of vacuuming performance, we probably won’t find any significant differences between the 711 and OZMO 920. The 711 will cover a smaller area per charge, but it’ll eventually get the job done.
Ecovacs Deebot OZMO 920 vs. 930
The OZMO 920 and 930 comes from the same generation of Deebots. Their differences are supposed to be minor, but that’s not the case here.
Taking a close look at their specs, there’s no point of difference. They’re both fitted with high-efficiency filters, are both OZMO models so have an optional mopping feature, are compatible with virtual assistants and the HOME app, and use the same Smart Navi 3.0 system. So what are the key differences?
Well, first of all, the OZMO 930 does NOT have the simultaneous vacuuming and mopping feature that the 920 does, which is quite odd considering their model numbers. This is not something to stress about, but it is a nice-to-have addition that makes the OZMO 930 stand out from the rest.
Another key difference is their respective brush designs. The OZMO 920 uses a Floating Brush 2.0 which adjusts its height based on whatever surface it’s currently cleaning. It can also reach deep into 4-mm spaces between tiles or floorboards. The OZMO 930, on the other hand, uses a simpler V-shaped brush which has been proven to be quite effective for cleaning multiple surfaces.
Overall, we conclude that the OZMO 920 is the superior model, though not by a lot. Every convenience-adding feature of the OZMO 920 can be found in the 930, except – if you want to count it – the mop-while-vacuum thing that the 920 has going for it. But since the 920 has not yet hit stores, the safer bet would be the go with the 930’s tried-and-true method of switching between both cleaning tasks.

Finally, we have the OZMO 950 – another robotic vac-mop combo-bot that has yet to be released. Like the OZMO 930, all information regarding what it’s packing under its hood is available online, so any conclusions we draw may not fully represent the real deal. But anyways, let’s compare the two.
There are several minor differences between the OZMO 930 and 950 that are worth addressing. The first thing is the smartphone app. Using the ECOVACS HOME App, you can adjust how much or how little water to use based on how dusty and sticky your floors are. Water-efficient mopping hasn’t really been the focus of mop bots, but we’re guessing that it will be the latest trend thanks to the OZMO 950.
The next minute difference is the number of suction-power levels. The OZMO 920 uses two – normal and MAX for carpets – whereas the 950 has an additional power setting known as MAX PLUS. This appears to be the ideal cleaning mode for shaggy carpets and rugs which we don’t mind at all. This is a must-have feature for those of us with wall-to-wall carpeting.
And finally, perhaps the largest minor difference between the OZMO 920 and 950 is the latter’s bigger battery. On a single charge, the 950 can work for up to 200 minutes (standard power), about 1-1/2 hours longer than the 920. With the recharge and resume feature built into the robot, the 950 practically guarantees that it’ll cover an entire floor of your home in one or two charges.
