Get your floors vacuumed and mopped with a single robot. The Ecovacs Deebot Ozmo 920 and 950 are two of Ecovacs’ most efficient robotic vacuum-mops. Both Ozmos are enabled with Wi-Fi, offering smartphone-based zoning and voice control. The 920 and 950 are highly responsive to their environment, and they can memorize the layouts of multi-story homes.

Ecovacs Deebot OZMO 920 vs. 950


Since the Ozmo 920 and 950 not only automatically dock but instantly resume cleaning post-charge, missed dirty spots aren’t a problem. However, the Deebot Ozmo 950 is equipped with a higher capacity battery. In turn, the Ecovacs Deebot Ozmo 950 runs longer than the 920 on a full charge, and it produces more suction whether on standard or max-suction mode.

Dual-Speed Suction

Deebot Ozmo 920
Some surfaces require more suction power than others. When the Deebot Ozmo 920 vacuums carpeting, its 600-pascal suction kicks up to 1.5 kilopascals, giving it the lift necessary to remove debris buried in between fibers. Even when suctioning at its highest speed, the sound level is quiet, hovering around 66 decibels.

The Ozmo 920 also has a dual-bristle brushroll, which helps the robot clean carpets and bare floors. With two side sweepers to complete its comprehensive vacuuming system, the Ozmo 920 pulls dirt toward the suction inlet and dusts along wall edges. From there, allergens are trapped by a high-efficiency filter while debris falls into the 0.43-liter bin.

It’s more difficult to get dirt out of carpets than off hardwoods or tile. Therefore, Ecovacs put a three-speed motor and a carpet-detecting sensor in the Deebot Ozmo 950. Together, the motor and sensor double the 750-pascal standard suction when cleaning carpets and further increase it when on max-plus mode. Regardless, the Ozmo 950 won’t exceed 66 decibels.

The Deebot Ozmo 950 doesn’t rely on suction alone to vacuum your floors. A pair of spinning brushes on either side of the robot help collect debris and remove dust from baseboards while the multi-surface brushroll attacks dirt on carpets and hard floors. Like the 920, the Ozmo 950 has a high-efficiency filter and a 0.43-liter dirt bin.

Conclusion: Both robots work well on many types of flooring thanks to their brushroll and two side brushes. However, the Ozmo 920 and 950 really shine when it comes to vacuuming carpets. Sensor technology increases both robot vacuums’ suction strength, but the Ozmo 950’s suction is a little more powerful than the 920’s.

Precise Water Distribution

Deebot Ozmo 920
Like its suction-boost function, the Ozmo 920’s mopping system is controlled by sensors. The sensors on the robot’s internal water pump know exactly how much water to dispense from the 240-milliliter reservoir, preventing streaks and oversaturation. Using the sensors, the 920 stops the flow of water when it’s on a carpet.

With the Deebot Ozmo 920, you get two absorbent mop pads. These pads are washable and reusable, saving more money in the long run compared to the disposable sheets that come with other robotic vac-mops. Due to their absorbency, the mop pads are able to disinfect your hard floors, removing 99.26 percent of germs.

Deebot Ozmo 950
Instead of inefficient mechanical controls, the Ozmo 950 has sensors that adjust the level of water that flows out of the 240-milliliter tank. Therefore, the robot won’t leave behind puddles or spots of water. Along with its ability to determine and adjust the water flow, the Ozmo 950’s sensors stop the flow when the robot comes touches the carpet.

Ecovacs includes two mop pads with the Deebot Ozmo 950, so you can wash one while you use the other. Each pad is made of microfiber that absorbs, not spreads, water. In turn, it doesn’t take long for the floor to dry. Since microfiber traps dirt by design, the mop pads can get rid of 99.26 percent of bacteria.

Conclusion: For both robotic vacuums, Ecovacs kept the same mopping system. While the reservoir is on the small side, sensors prevent wasted water, pools and streaks on hard floors as well as water damage and stains on carpets. The 920 and the 950 come with two microfiber pads to minimize downtime. Plus, these pads are highly efficient at bacteria reduction.

Charges, Cleans, Repeat

Deebot Ozmo 920
Auto recharge and resume is the gold standard for robotic vacuums, and that’s just what you get with the Deebot Ozmo 920. After vacuuming or mopping for 110 minutes, the Ozmo 920 heads to its charging dock. In about 4 hours, the 3.2-ampere lithium-ion battery will fully charge, and the 920 will start cleaning again.

Deebot Ozmo 950
The Ozmo 950 not only docks itself to the charger but also continues cleaning after the battery replenishes. Inside this robotic vacuum, there is a 5.2-ampere lithium-ion battery that gives the 950 a runtime of 200 minutes. With such an extensive working time, the Ozmo 950 can easily cover 350 square feet of floor every cleaning cycle.

Conclusion: Both the Ozmo 920 and 950 resume vacuuming or mopping at the last-cleaned spot after they recharge their own battery. Ecovacs chose to use a lithium-ion battery for each robot, which means the suction won’t fade as the charge level decreases. While 110 minutes is lengthy, the Ozmo 950’s 200-minute runtime is extraordinarily long.

Multi-Story Mapping

Deebot Ozmo 920
The Ozmo 920 utilizes Ecovacs’ proprietary Smart Navi 3.0 technology. This laser sensor helps the 920 learn the layout of your home as well as create and remember three maps. As it moves around your house, a series of ledge and object-detecting sensors protect the Ozmo 920 from stairs and other dangers.

External components add another layer of protection to the Deebot Ozmo 920, such as the robot’s thick bumper. Two rubber wheels allow the 920 to climb over door thresholds up to 0.6 inches as the robot moves in a logical back-and-forth pattern. With a height of about 3.5 fee, the robot is even able to clear some furniture.

Deebot Ozmo 950
Using a multitude of infrared sensors, the Ozmo 950 pinpoints the location of stairs, drop-offs, furniture and random objects, avoiding falls and collisions. Laser mapping via Ecovacs’ Smart Navi 3.0 technology enhances the 950’s navigation beyond the infrared sensors by memorizing floor plans for as many as three different stories.

The laser sensor moves the Ozmo 950 in a time-saving, efficient pattern. The robot also has a shock-absorbing bumper to prevent damage in the event of accidental collisions as well as a pair of wheels with a 0.79-inch climbing ability. Instead of being stopped by cabinet doors, its height of 3.66 inches allows it to clean alongside kick plates.

Conclusion: Each of these Deebot Ozmos uses infrared and laser sensors; therefore, both of them map and memorize layouts as well as scope out and steer clear of obstacles. Laser navigation ensures the robotic vacuums take the most logical path through your home. For extra protection, Ecovacs added a bumper and sturdy wheels to the 920 and the 950.

While the Ozmo 950 has a convenient auto-start onboard button, the Ecovacs HOME app provides more, including zone cleaning and virtual boundary creation. The app also lets you spot clean, change the water-distribution level and manually navigate. You can even get status alerts concerning the 950’s coverage area and battery charge.

For further automation, use the app to set a schedule and make the 950 clean every day, every other day or every few days at the time of your choosing. Voice commands such as start, stop and dock are also a possibility when you teach Alexa or Assistant the Ecovacs skill.

Conclusion: These two robotic vacuum-mops come with all the premium control options you could want. The smartphone app’s highlighting feature is its interactive map. The scheduling and spot cleaning functions also come in handy, and voice command takes convenience to a whole new level. If your Wi-Fi goes down, the onboard start button lets you begin a cleaning session.
