Frequently Asked Questions

Yes. The VITERIO Claro is designed for large flat glass surfaces: bay windows, patio doors, verandas, and landing windows. It maintains its adhesion by suction on glass 3 to 8 mm thick, according to manufacturer data. The surface must be flat, without texture or pronounced recessed joints.

Yes. The VITERIO Claro works on single, double, and triple glazed windows. The presence of a spacer between the panes does not impact the robot's operation, as it only works on the exterior or interior side of the glass.

Yes, on flat tiled surfaces without pronounced recessed joints. Large format tiles (60x60 and larger) offer the best adhesion conditions. Mosaics and wide joints are not compatible with the robot's suction system.

Yes. The VITERIO Claro is compatible with bathroom mirrors, provided the surface is flat and not framed by a protruding edge that would block the movement of the discs. For limescale stains due to hard water, lightly moistening the cloths before use improves the result.

The robot can work on frameless surfaces provided the safety rope can be attached to an adjacent fixed point (railing, wall structure, rail). Without a possible anchor point, use on large frameless surfaces at height is not recommended.

The robot is not suitable for very sloped surfaces (angle greater than 15° from vertical), textured or frosted glass, mosaics and tiles with wide joints, surfaces with film delamination or cracks, and windows too narrow to allow the safety rope to be attached.

The result largely depends on the condition of the cloths. A clean, slightly damp microfiber on a room-temperature window produces the most even result. Changing the cloths as soon as they appear gray reduces the risk of dirt redistribution. Avoid cleaning in strong direct sunlight: the liquid dries too quickly and creates white streaks.

For light dirt and dust, the cloths can be used dry. For rain streaks, limescale, or greasy splashes, moistening the cloths with clean water or a 10% diluted water-white vinegar mixture is sufficient. Avoid products containing concentrated alcohol or abrasive agents, which degrade the fibers and leave residues on the glass.

The robot's round discs cannot geometrically reach corners closer than about 5 cm from the edges. On large flat surfaces, this limitation is barely noticeable. On smaller windows, a quick manual finish with a dry cloth in the corners completes the result.

On a standard 2m x 2m bay window, the robot generally covers the surface in about twenty minutes, depending on the level of dirt and the selected program. During this time, no manual intervention is necessary.

No. Once the robot is placed, the safety rope attached, and the program launched, you can do other things. However, it is advisable to stay nearby during the first use to check the smooth running of the cycle and the stability of adhesion on your type of glass.

The robot emits noise related to the rotation of the discs and the suction system. The sound level is comparable to that of an office vacuum cleaner. It can be used during the day without particular inconvenience, but its noise may be noticeable in a quiet room.

A pass every two to three weeks is sufficient for windows exposed to rain or dust in urban or suburban areas. In rural areas or with high pollen exposure, a weekly pass may be necessary in spring. Regular maintenance prevents the accumulation of limescale deposits that would require a specific descaling agent.

The robot stays on the window by active suction. A safety rope with a carabiner is included in the package and must be attached to the window frame before each use. It keeps the robot in position in case of temporary loss of adhesion. On high windows, attaching the rope is mandatory before any start-up.

The VITERIO Claro operates only on mains power via a 230V adapter and a 4-meter extension cord included in the package. There is no internal battery, so the cleaning duration is not limited by battery life. An accessible electrical outlet near the window is required before use.

The VITERIO Claro package includes: the window cleaning robot, a remote control, a power adapter with a 4-meter extension cord, 10 washable microfiber cloths, 2 fixing rings, a safety rope with a carabiner, and a user manual in French.

The microfiber cloths are machine washable at 40°C, without fabric softener (fabric softener reduces fiber absorption). Rinse them with cold water after each use to remove dirt residues. They are reusable dozens of times before needing to be replaced.

No. Startup involves three steps: attach the cloths to the discs, place the robot on the window after plugging in the adapter, then press the start button. The remote control allows you to start, stop, and change programs without touching the robot. No mobile app configuration is required.
