Ecovacs Deebot T80 Omni

Suction in pascal, as the maker measures it. More pascal helps on carpet, but it says little about how well the robot picks grit off a hard floor.

A brush that guides hair to the side instead of letting it wind around the shaft. It saves the cutting work in homes with long hair or pets.

The side brush swings out in a corner or along a kickboard, so the dust there is swept in too. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.

The robot notices when it drives onto a carpet. Most then raise their suction, and a mopping robot lifts its mop or leaves it at the dock.

Whether the robot copes with pet hair: a brush that hair does not wind around and a dock that empties the bin for you. Where the maker does not say so itself, we read it from those two.

How the mop is built: flat pads, a vibrating pad, two spinning discs or a roller. Discs press harder on dried-on dirt, a roller rinses itself while it works. On this model: from the maker's product text, not from a specification table.

How far the robot lifts the mop when it drives onto a carpet. From about 10 mm a medium pile stays dry.

The pad slides out along a wall or a kickboard, so the last few centimetres are mopped as well.

The robot leaves the mop at the dock before it vacuums a carpet, so the carpet never gets wet. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.

The robot returns to the dock during a run to rinse the mop, instead of pushing dirty water around. On this model: from the maker's product text, not from a specification table.

How much clean water the robot carries. It sets how long it mops before a refill, which a dock does by itself.

The robot or its dock works with steam. It loosens dried-on dirt and grease, or washes the mop hotter than water alone. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.

The dock empties the robot’s dust bin, usually after every run. You only empty the dock’s bag or bin.

The noise in decibels while the dock sucks the dust out of the robot’s bin, as the maker states it. It lasts a short while after each run and is louder than the cleaning itself: 70 dB is like a vacuum cleaner, 80 dB like a hair dryer. Where the maker gives two settings, the louder one is shown.

The dock collects dust in a bin instead of a disposable bag. No bags to buy, but you empty it yourself. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.

How much the dust bag in the dock holds.

How long the maker says a dust bag lasts with daily use. With pets or a lot of carpet it is shorter.

The dock washes the mop for you, so you do not rinse it by hand.

How hot the dock washes the mop. Above 60 °C grease comes off, which is what keeps a mop from smelling.

The dock dries the mop afterwards, so it does not sit there wet and start to smell.

Drying is done with warm air instead of cold. It is faster and it helps against smell.

How warm the air is that the station dries the mops with. Warmer air dries faster and keeps smells away better.

The dock mixes detergent into the water itself, from its own bottle.

The dock can be connected to the tap and the drain, so you never fill or empty a tank. It does need a connection nearby.

The clean water tank in the dock, which wets the mop.

The tank that catches the dirty water from the mop. You empty this one yourself.

The width, depth and height of the dock. Measure the spot you have in mind, and leave room for the lid and for the robot driving in.

How the robot maps your home and follows that map. Lidar measures with a laser and works in the dark, a camera looks along and recognises more.

How the robot sees loose things on the floor, such as cables, socks or a pet accident. A camera with depth sensing sees more than a bumper that reacts on contact. On this model: from the maker's product text, not from a specification table.

The highest threshold the robot takes, as the maker states it. Measure your own: the step into a bathroom or onto a balcony is often higher.

An extending leg or wheel that carries the robot over a high threshold. Without one it usually stops at about 2 cm. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.

Whether the robot has a camera, and what for: to recognise obstacles, or also to show you a live picture of your home in the app.

Sensors under the robot that see a drop, so it stops at the top of a staircase instead of falling down it.

An arm on the robot that picks up small loose things such as socks, so they are not in its way. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.

How tall the robot is. It decides whether it fits under your sofa, bed or cabinet.

How wide the robot is. Narrower gets between chair legs more easily, wider usually means a bigger dust bin.

What the robot weighs. It counts most if you carry it up a staircase every day.

How much dust the robot holds before you empty it. It matters less with an auto-empty dock, which empties the bin after every run.

The noise in decibels while cleaning, in the setting its source names: makers mostly give the standard setting, shops often the highest. 65 dB is like a vacuum at half power, 55 dB like a conversation. Emptying by the dock is louder and listed on its own.

The capacity of the battery. It hints at the runtime, but how much the robot draws counts just as much.

How long the robot cleans on one charge, at its quietest setting. After that it recharges and carries on where it stopped.

How long an empty battery takes to charge fully in the dock.

Matter is the standard that lets devices from different makers work together. With it you can run the robot outside the maker’s own app. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.

Which voice assistants the robot works with, such as Google Assistant or Alexa.

The warranty the maker gives in the Netherlands. Consumer law here stands apart from it and can last longer.

You set days and times, and the robot starts by itself, also when you are not at home.

Whether the robot works with Home Assistant, the home automation software you run yourself. Official means the integration comes with Home Assistant itself, community that volunteers maintain it.
