The Scout RX1 robovac by Miele incorporates a systematic navigation system that covers the area to be cleaned in parallel tracks instead of randomly crisscrossing the room – the more common approach adopted by the majority of robot vacuum cleaner which use chaotic navigation.
The MIele Scout RX1 navigation system achieves more reliable coverage and saves time and battery power to boot. Furthermore, complex floor plans involving several rooms can be vacuumed in their entirety, including return trips to the base on completion of the task and for recharging.
Miele Smart Navigation relies in the first instance on a so-called gyro sensor which measures rotation and changes in direction. This alone would be sufficient to systematically clean a room. Besides this, though, the Scout RX1 has a high-quality digital camera on board which scans the ceiling of the room several times a minute to ensure additional precision. The interplay of gyro sensor and ceiling-scanning camera ensures that the perimeters of rooms and difficult-to-access areas are cleaned without gaps. Furthermore, the Miele robovac has 7 infra-red sensors on the front of the unit. These scan a 180° area ahead of the machine in order to avoid collisions with furniture and other obstacles. In contrast to most other common systems on the market, these sensors stop the vacuum cleaner in good time before a collision occurs. 3 further sensors below the unit prevent the Scout RX1 from falling down stairs.
Particularly effective cleaning is guaranteed by the Triple Cleaning System. Two long rotating side brushes target difficult areas along the walls of rooms or along items of furniture and sweep dirt towards the center of the unit. Once there, a removable beater bar picks up coarser particles. In the third stage, a fan transports the finer dust into the dust box. This container has a capacity of 0.6 liter and can be removed at the touch of the button. An AirClean filter ensures clean room air.
4 cleaning programs guarantee maximum cleaning convenience. In Auto mode, Miele Scout RX1 travels through all rooms. Spot mode is intended for a defined area of at most 1.80 meters square, for example to clean up crumbs from under the breakfast table. In Corner mode, all rooms are first cleaned in Auto before returning to clean all edge areas once again. For particularly fast cleaning, Miele offers its Turbo mode in which the robovac cleans the entire home but travels in straight lines with greater spacing. In this case, cleaning is somewhat more thorough than in Auto mode but only takes half as long.
Overall, a battery charge is able to clean an area of up to 150 m², corresponding to a duration of approximately 120 minutes. When cleaning larger areas, this Miele vacuum robot pauses as and when needed to return to its base for recharging. Work is automatically resumed after approximately 2 hours at the precise point where cleaning was interrupted earlier. Even after 300 recharging cycles, the battery still has the capacity it had when new. With this combination of battery charge and battery life expectancy, Miele currently represents the benchmark on the robovac market.
The Scout RX1 has good traction on all common floor coverings and is even able to negotiate height differences of up to 2 cm, for example thresholds and the edges of rugs. Rooms or areas which are to be excluded from cleaning can be cordoned off with a magnetic strip. The Scout RX1 is started either at the controls on the unit itself, using the remote control handset or by programming the timer to start and finish at predefined times.
The design of the Miele robovac is both high-quality and elegant. This is achieved for instance by the white characters on a black background in the display which are not only easily legible but also blend in perfectly with the Miele product family design. A rear-printed plastic insert on the top of the machine further underlines the noble overall impression. Price is around $900. Miele.
