Hobot Legee 7 test: a formidable 4-in-1 robot mop

Hobot’s Legee 7 recovers some iconic elements of Neato robot vacuums: the D-shaped architecture and a laser rangefinder nestled on the hood of the robot mop. Obviously, this configuration adds a few centimeters of height to an already very thick robot mop: 12 cm vs 9.9 cm for the Legee 688. In this, the robot has a hard time going to clean under the lowest furniture.

Unlike iRobot’s Braava Jet m6 which houses its sprayer on the front, the Legee 7 has 4 located under the device that allow it to spray the wipes evenly. These are two in number and vibrate up to 600 times per minute to brush the ground.

On the top of the device, there are 4 buttons to start a dry or wet cleaning, interrupt it or ask the robot to return to its base. But to access all of its features as well as the various cleaning programs, it is essential to go through the mobile application – in the absence of a remote control, unlike its predecessors.

Connectivity and application

The configuration of the robot to the Wi-Fi network is very well detailed in the application. You must have your smartphone connected to Wi-Fi, download the application, create an account and follow the steps indicated. The operation takes less than 3 minutes.

Once the robot is connected, you can access the 7 cleaning modes: Standard, Intensive (strong suction), Animal, Eco, Kitchen, Dry cleaning, or even Polishing. By choosing one of these modes, the robot automates the power of spraying, suction, washing frequency and cleaning speed. Those who want to go further can customize a cleaning mode. In this case, it is up to them to adjust the parameters mentioned according to their needs. To all this are added 4 modes of movement: Automatic (for a complete cleaning and a return to the base), Fast (in zigzag to cover all surfaces), Targeted (suitable for confined spaces, the robot provides a spiral cleaning in starting from the center) and Along the walls (for room borders and plinths).

When the robot starts a cleaning session, it maps its environment in real time. The user can follow his movements live, have an overview of the cleaned surface, the selected cleaning mode and the duration of the cycle. The Legee 7 can memorize 5 different maps, which is useful if there are several levels to clean. After a first cleaning, the Legee 7 will demarcate the rooms on its own and the user will be able to program cleaning modes according to the rooms – and request more intensive cleaning in the kitchen than in the bedroom, for example. The good news is that this new generation allows the creation of virtual beacons that prevent the device from accessing certain rooms or areas of the room (around rugs, for example).

Obviously, the application also gives access to basic functions, but at the very least essential, such as the weekly programming which is very refined here: the user can define the frequency of cleaning, its duration, possibly the areas to be cleaned, and the cleaning mode. A tailor-made cleaning in short!

A virtual remote control (with directional keys) allows the robot to be piloted to take it where the user needs it, but for this – and for security reasons – it is essential that the robot and the smartphone are synchronized on the same wifi network.

Interesting features: icons allow you to view the battery status, of course, but also the water level in the tank and the level of the dust collector.

Under the hood of the Hobot Legee 7, there are two tanks: a first water tank of 340 ml and a dedicated dust container (500 ml). The latter has a water-washable pre-filter and an anti-allergen pre-filter.

If the dust collector is removable, the water tank is screwed on. To fill it, it is necessary to use the small gourd with a pointed tip. Hobot designed this system to better secure his device.

As for the wipes, they install really very easily by scratching, quite simply. When they are dirty, it is sufficient to clean them at 60 ° C. As for the side brush, it can also be detached to be thoroughly cleaned. Finally, what is the least practical to clean is the front of the device, covered with a shiny black plastic which very readily retains fine dust.

Thanks to its laser rangefinder, this robot mop is much more methodical in its movements. It systematically begins by skirting the walls, the plinths, to then vacuum the interior, in a zigzag fashion. It thus ensures perfect coverage of the room, while being fast and efficient.

The obstacles are fairly well managed. The robot visualizes them fairly well and always defends itself from approaching them to avoid hitting them. Trapped between 20 feet of chairs and tables, it easily manages to extricate itself without ever asking the user for help. As for the electric cables, he never got entangled in them.

However, this Hobot is struggling to pass the thresholds of doors a little high. Its design is such that the base which accommodates the wipe prevents it from passing through the threshold bars and certain chair legs. It will be necessary to lend him a hand to move from one room to another. On the other hand, it is another kettle of fish for the thin rugs on which he climbs very willingly.
The Legee 7 is not able to recognize the surface it is on; it’s a shame and all the more surprising that the Legee 688 avoided this pitfall.

To evaluate the washing efficiency, we deliberately dirtied the floor of our test lab by carrying out several types of stains on the floor: sugary drink, mixture of water and carbon black, oil and lipstick. (fat).

After a first passage of the robot set in Standard mode, we noticed that the ground was still a little oily where we had spread the oil; it only took one more pass for it to disappear completely. It took three passes to completely remove the sugar stains (after two passes the soil was still sticky) and mixed carbon. Finally, the lipstick stains were faded, not erased.

To optimize washing performance, we relaunched the robot in Kitchen mode (suitable for spills and stubborn stains). By the end of the cycle, the fat was completely gone, along with the sugary drink and traces of carbon. Lipstick was always visible – as is the case with all robots.
