Cleaning Vacuum Robots in The Smart Home

Especially for those who don’t like cleaning, vacuum robots are welcome roommates in the smart home. Modern devices take care of any cleaning work – without complaining and grumbling. You can find your way around the apartment easily, and you can also pick up the dirt from remote nooks and crannies.

The top vacuum cleaner from Ecovacs does a great job! It navigates confidently and quickly through the rooms and collects almost all of the dirt. The camera-based obstacle detection does not (yet) work flawlessly, but it saves you a lot of sock or cell phone cord that has been eaten away. In the past it was often eyewash, but the wiping function with powerful swiveling and shaking movements has earned its name for the first time. This makes the Deebot Ozmo T8 Aivi currently the best suction and wiping combination on the market.

Dyson 360 Heurist: The stylish clean man
The current Dyson vacuum robot costs a proud 999 euros and thus significantly more than flatter competitor vacuum cleaners, which also offer a wiping function. You have to give the 360 heurist one thing: when it comes to suction power and thoroughness – especially on carpeting – it leaves a lot of competitors behind. For faster cleaning and better navigation, Dyson urgently needs to add a software update.

Yeedi and Co.: The bargain suckers
Neatly cleaning entry-level devices at a great price come from Yeedi. The Yeedi K650 and the Yeedi 2 Hybrid both score with a wipe function as well as app and Alexa control. Thanks to smart sensors, they can find their way around the room to some extent, but they need a long time for their cleaning trips. There is no laser navigation for more thorough and faster cleaning and there is no virtual map in the app on which rooms and zones can be created. Other bargain suckers that do just as well as the Yeedi come from Zaco and Neato.

Chaos principle or laser: which works better?
When it comes to vacuuming, the robots follow two fundamentally different strategies:
Chaos principle: Inexpensive devices from 80 euros drive around unstructured around the area until they hit the baseboard or chair leg. You then turn around and take a different path, including wanderings. Disadvantage: It takes a long time to clean and some corners and niches remain untouched – not smart enough for this test!

Intelligent room recording: The devices in this test article have camera or radar-based sensors or laser technology on board. The robots use this to measure the rooms with pinpoint accuracy and create a virtual map. The robot always knows where to go and systematically travels through the rooms lane by lane. The wild driving back and forth has had its day. This pays off especially in larger and angled apartments with many rooms. Disadvantage: The devices are more expensive, the test candidates cost between 300 and 700 euros.

Vacuum robots put to the test: that’s what counts
Anyone who buys a vacuum robot does not want a roommate that requires intensive care, but rather effective help in the household. These functions and properties are important and can be decisive when choosing the right cleaning aid for your own home:

Height and diameter: The best vacuum robot is not good if it cannot get to the dirt. Most of the devices in the test measure 33 to 35 centimeters in diameter. This is usually compact enough to skilfully snake around chair and table legs. There are differences in height: Some suction cups protrude a full 10 centimeters and more, while others are much flatter and so come better under many beds, sofas and chests of drawers.

Cleaning performance: Bargain devices often do without a powerful motor and simply suck dust and crumbs through a slot. This is not the case with the devices in this test: They work the floor with powerful rollers or roller brushes. Often, rotating side brushes push the dirt towards the opening. It is practical if the cleaning aid masters different suction levels or even switches the suction power independently depending on the surface (Ecovacs, Roborock, iRobot and Eufy). In the stress test, the candidates had to show what they can do. Ecovacs, iRobot and Roborock collected the dirt particularly thoroughly (more than 90 percent) and also worked off corners conscientiously. Eufy and Medion, for example, delivered solid mediocrity. Other suckers only got away three-quarters or less.
Endurance: A long battery life is also important. Some vacuum cleaners have to be returned to the charging station after just 90 minutes. That’s enough for about 80 square meters. Those who want to suck more, prefer to use durable models that can last up to three hours. After all: at the end of the cleaning marathon, most vacuum cleaners automatically return to the charging station, fill up the battery and continue cleaning exactly where they left off before charging.

Most of the vacuum cleaners drove independently to the charging station in the test to refuel the battery. They then finished their cleaning tour with a full charge.

Smart control: All devices in the test couple with the home WiFi and can then be conveniently controlled via the app. The applications show virtual maps in which cleaning plans can be defined or rooms and restricted areas can be entered in the floor plan. In addition, remote access works when you are out and about or at home via voice control. With Amazon Alexa or the Google Assistant, the vacuum cleaners can also be sent on demand.

Capacity: Vacuum cleaner bags are leftovers from another time and have no place in modern robots. The sucked in dust and dirt usually ends up in a plastic box inside the vacuum cleaner. The slim devices usually only digest 0.2 to 0.5 liters of dirt. The cleaning assistant should be able to hold at least 0.3 liters if he is to do his laps every day. Important: The plastic box should be easy to remove, quickly emptied and easy to clean.
Volume: Pay attention to the volume at which the vacuum robot is on the move. Some boom with almost 60 decibels (dB) – about as loud as a dishwasher. Other powerful models achieve the noise level of piano playing or road traffic with up to 90 dB. Watch TV on the side? Is difficult.
Vacuum cleaner with wiping function, fill water tank.

Those who want help not only with vacuuming but also with mopping can choose models with a water tank (picture) and a mopping mat.
