Ecovacs DEEBOT OZMO 900: robot vacuum cleaner with wet cleaning and mapping skills

Ecovacs DEEBOT OZMO 900 – robot vacuum cleaner with dry and wet cleaning function. It is claimed that the robot has no problems with cleaning hard surfaces, carpets (except for the most fleecy options) and easily handles the hair of Pets. The kit includes replaceable brushes for different purposes, and there are also different modes of suction intensity, including automatic power increase on carpets. For wet cleaning, the OZMO system is provided with adjustable water supply intensity.

The robot can overcome obstacles up to 16 mm in height, and it can work for up to 90 minutes on a single charge. There is a set of sensors to protect against collisions, bumps and falls from the stairs. But one of the most interesting features is the built-in laser rangefinder and Smart Navi 3.0 system for building a map of the area to be removed. This allows you to calculate the route more efficiently, select separate areas for cleaning, and use “virtual” walls to mark areas that the robot does not need to enter.

Of course, the robot has a Wi-Fi module and its own application for managing it. It supports working with Google Assistant and Amazon Alexa voice assistants.

How do I use it and how does the cleaning process work?

The first step is to install side brushes on the robot, connect the base to the network and install Ecovacs DEEBOT OZMO 900 on it. Next, to start the basic automatic cleaning, you need to perform just a few simple manipulations: turn on the power slider and press the power button. For wet cleaning, you will need to add filling the tank with water and installing microfiber to these manipulations.

But to access all the features, you should connect a smartphone with the ecovacs branded app. The smartphone and robot are connected to the same Wi-Fi network, and it must be 2.4 GHz. There is no support for 5 GHz. How to do this — the app itself will tell you when you first connect. The process is extremely simple.

How well does it clean?

To begin with, it is worth remembering that Ecovacs DEEBOT OZMO 900 can do dry and wet cleaning. And “wet cleaning” is not washing floors, it is worth considering and do not expect the robot to cope with dried dirt or something similar. But, in fact, the hero of the review in this regard was able to pleasantly surprise: with dried spots from coffee or juice, he copes. Which, to be honest, I didn’t expect. I think that it will also be able to cope with a little more complicated pollution, but it will probably need to start intensive cleaning of the selected area and it will be done in a few repeated visits. If you compare it with the more affordable Ecovacs DEEBOT OZMO Slim10, the OZMO 900 copes better: the brush helps a lot. And faster, which was expected: a map of the area is a useful thing.


Ecovacs DEEBOT OZMO 900 gives the impression of an optimal robot vacuum cleaner for every day with all the necessary set of modes and functions, while not at an exorbitant price. It copes well with its main task: it keeps the house clean, can do wet cleaning, collect animal hair and clean simple dried stains from liquids. There is a full set of convenient functions that will make handling it even easier: different cleaning modes, automation of this process on a schedule, voice notifications, indication of wear of consumables and management of voice assistants. To all this, we added the function of building a map of the room, which makes life easier for the robot itself, and adds useful little things: a virtual wall, zonal and customizable cleaning. The model may not fit if there is a lot of low furniture, under which the OZMO 900 simply can not climb. Well, if you need a washing model for serious contamination, you will have to look at something more expensive.
