Modern styling represents high quality
The modern styling in combination with the functional design underlines the robust character of the mower. TANGO E5 has been designed with consistancy, functionality and weight in mind.
A durable chassis protects the mower from impacts and weather
The TANGO E5 is strong and rigid, built using a solid, double walled chassis. The inner part of the body is sealed against the hood. All electronics are inside the double-wall body, protecting them against dirt, dust, moisture, and other outside interference. Solid acrylonitrile styrene acrylate (ASA) material is highly resistant to sunlight.
The predominant red stop button immediately aborts all operations of the TANGO
The strategically placed red stop button is on the top of the mower, easily visible and accessible. Pushing it will abort any operation immediately. On either sides of the button are decals which explain safe operation of the mower.
The main switch turns the mower on and off for transportation and storage purposes. It is located next to the carrying handle at the rear, facing down. The switch is not directly visible from the top. This prevents unintended activation of the mower by untrained people.
Sensors assist the TANGO in its mowing operation
Boundary sensors (highlighted in red), indicate the mower’s position in relation to the boundary wire.
Should the TANGO be inadvertently lifted during its operation, the sensor in the handle and the two front caster wheel sensors will detect this and shut the mower off immediately. The TANGO also features a built-in tilt sensor that instantly stops the mower whenever it is raised more than 35 percent (20 degree).
Four boundary sensors indicate if the mower is operating within the area defined by the boundary wire. Outside of this area, the mower will neither drive nor spin the blade. If the mower encounters an obstacle even at low force, it will stop and resume mowing in another direction.
The durable charging station provide power for both the mower and the boundary wire
After TANGO E5 has been mowing a while and the battery loses charge, the mower automatically drives back to the charging station to recharge. The mower is charged via two metal plates in the charge station, touching two metal contacts at the front of the mower. The charge station receives the necessary 36-V electric power from a voltage converter connected to house electrics (AC 120 V/50 Hz or 220 V/60 Hz). The maximum charge time is 80 minutes.
With a fully-charged battery, TANGO E5 can operate for an average of 90 minutes. Note that the actual mowing time depends on cutting frequency, slopes, complexity of the garden, etc. A professional installation along with the machine's smart navigation features allows maximum mowing time per battery charge. To better protect the mower against theft, charging station and mower will be paired.
The charge station also provides power to the boundary wire around the garden which defines the mowing area as well as to the guide loop which aids the mower to align with the station when going for recharge. A green light-emitting diode (LED) on top of the charge station clearly indicates the status of those wires, allowing quick and easy diagnostics should the wire get broken.
To protect the charge station’s circuit board in freezing winter conditions, the solid charging station can easily be taken off the charge-station pad and stored, for example, in the basement. A cover encloses the connectors for the boundary wire during mowing season. When taking off the charge station in winter, this cover folds down to continue protecting the cables from weather impacts.
Lithium-ion (Li-ion) battery offers high power and long life
TANGO E5 uses a Li-ion battery for power supply. The battery delivers 98 Wh at 25.2 V - enough power for outstanding drive and cutting performance. Li-ion batteries provide high power at low weight keeping the mower light. There is nearly no memory effect so the battery capacity does not decrease over time. This along with the very low self-discharge rate, maximizes battery lifetime.
Smart navigation enables the TANGO to cover the entire lawn in the least amount of time
There is a big difference between traditional and autonomous mowing. The traditional method is to mow your grass lower than average and let it re grow before cutting it again. Autonomous mowing takes place continuously, maintaining the grass at the desired pre-set height throughout the week.
As per the short-grass-short principle, the mower can also operate in wet conditions as the short grass clippings do not clump and leave an unsightly finish. The autonomous mower will operate within boundaries defined by wires installed in the garden. It operates randomly on the lawn at given times. Whenever the battery power becomes low or scheduled time is over, the mower will return to its station to charge and idle until the next mowing sequence is scheduled.
Cutting every corner even of complex gardens
While the boundary wire defines the borders of the entire garden, it can also be used to create keep-out areas such as flower beds where the mower should not mow. To cut hidden corners of the garden, TANGO E5 will drive to launch points along the boundary wire and start mowing from there. Up to five launch points can be adjusted.
Modifying the frequency starting from the various launch points, as well as the charge station, ensures even coverage of all garden sections. A cleanup lap around the entire garden boundary ensures all edges will be well-maintained. The frequency of this cleanup pass is adjustable.
Homing and automatic charging
Once the battery level gets low, TANGO E5 will return home by traveling next to the boundary wire until finding the charge station. As the mower using different routes during its homing process, tracks will be avoided. Once reached, a guide wire in front of the charge station helps the mower to align with the charge station.
In addition to this home-finding along the boundary wire, the smart-homing feature is built-in. In the same way you may fuel a car when reaching a convenient fuel station shortly before reaching critical fuel level, TANGO will charge its battery when being next to the charge station before power goes low. This provides more time to mow instead of traveling and less tracks in the garden is your benefit.
Vehicle Control Unit (VCU) is the control centre for the mower
The VCU is mounted inside the mower to ensure protection for the elements. The VCU connects all sensors, motors, and power harnesses and contains an accelerometer providing slope angles as well as the speaker for audible signals.
Powerful, maintenance-free drive motors power the rear wheels
Sturdy and powerful brushless motors are used to power the drive wheels. The two identical motors power the rear wheels through an integrated planetary transmission.
Easy height of cut adjustment
The cutting height adjustment is done quickly and easily by simply turning the protection shield. The Blade and shield move simultaneously, another added safety feature of the TANGO. The height of cut ranges from 19mm to 102mm.
The traditional method is to mow your grass lower than average and let it re grow before cutting it again. Autonomous mowing takes place continuously, maintaining the grass at the desired pre-set height throughout the week.
Powerful and maintenance free motors power the cutting blade
The blade is driven by a brushless motor which requires no maintenance. Well-protected from rain, grass, and impacts, the motor resides in the height-of-cut assembly, moving up and down with the blade when changing the height of cut. It offers a powerful 60 W at 2600 rpm.
Durable blade offers long-lasting, high-quality cut with low noise, emission and power need
The high quality cutter blade offers perfect cut performance all season long. Should the blade hit a hard object and stop suddenly, the blade motor is protected from the impact by the blade mounting shim which allow the blade to stop immediately without causing any damage. The shape of the blade means only the sharp cutting edges are in contact with the grass, reducing noise and power requirements.
Our experience shows that in many applications, one single blade can be used an entire season; whilst other autonomous mowers in the market would require blade change frequently.
A Large user interface provides clear mower status information and easy activation of the operation modes
TANGO has the best-in-class user interface in the industry. The large, six-line display is easily visible from a distance. The intuitive operation of the mower was the key objective while designing the user interface.
On the left part of the user interface, there are buttons for quick access to the main operations: mow on schedule, mow now, and go home. The right section of the user interface is reserved for the buttons to program the mowing hours and change further settings. Light-emitting diodes (LEDs) clearly signal current operation mode and potential faults.
