Multi Surface Window Cleaning Robot
Model:309
LIESA manufactures the multi surface window cleaning robot in Qingdao, China, for buyers who need one machine to cover glass, mirrors, smooth tiles and polished panels rather than a dedicated unit per surface. Pad grade and water volume are matched to the surface in use. Liesa Intelligent Technology has built cleaning appliances in Qingdao since 2014, with OEM pad sets and branding.
Smooth, non-porous surfaces beyond windows can also be cleaned with the Multi Surface Window Cleaning Robot, including mirrors, shower screens, glass cabinet doors and polished worktops. The same suction platform maintains contact where an airtight seal can be formed, while the cleaning settings can be adjusted to suit different surface conditions.
LISA, a China supplier of cleaning robots, applies the same platform to multi-surface cleaning with attention to microfiber type, spray volume and surface suitability. Abrasive materials should not be used on surfaces that may be scratched.

Matching Pad and Water to the Surface
Fibre grade follows the dirts and the finish. Fine or nano-fibre for mirrors and coated glass, where fibres and residue show in raking light; standard microfibre for tiles and panels; short pile for wet areas such as a shower screen, where soap film needs more water and faster drying. Spray volume is set with the fibre so the film is even rather than heavy.
Surfaces that cannot be cleaned are stated just as clearly. Textured tile, frosted or filmed glass, rough stone, bare wood and any surface with loose grit are outside the design brief, because the seal cannot be established or the multi surface window cleaning robots cannot maintain contact.

The table is also the basis of the accessory set. Three pad grades are usually ordered and labelled by surface so the wrong pad is not used on a mirror.
Cross-Contamination Between Surfaces
A machine that moves between a kitchen splashback and a bathroom mirror carries what it has picked up. Grease from a splashback on a mirror pad leaves a smear that takes two passes to remove, and grit from a tiled floor area scratches glass. Separate pad sets and a rinse between areas are the whole answer, and both are cheap to specify.
Water is part of the same discipline. Filtered water is used for mirrors, while a mild neutral cleaner is added only where the surface is not coated and the buyer confirms it is suitable. That keeps the same machine usable across a house without risking a coated surface.
OEM and Order Notes
The multi surface window cleaning robot is supplied as OEM work on pad grades, pad labelling, body colour, logo, carton artwork, manual language and accessory sets. Surface suitability statements are part of the OEM brief so the buyer's listing matches the machine's real capability. Minimum order quantity, tooling and lead time are confirmed with the quotation.

FAQ
Q: Which surfaces can the multi surface window cleaning robot clean?
A: Smooth, non-porous surfaces: window and door glass, mirrors, glass cabinets, smooth tile, polished stone and shower screens. Textured or filmed glass and rough stone are not suitable.
Q: How does one machine suit different surfaces?
A: Through the multi surface window cleaning robot and the spray setting. Fibre grade follows the finish and the dirt, and water volume is matched to the fibre so the film stays even.
Q: Should the same pad be used on a splashback and a mirror?
A: No. Separate pad sets and a rinse between areas stop grease and grit being carried onto a mirror, which is where the carry-over shows most.
Q: Is a cleaner used or just water? A: Water alone is the default.
A mild neutral cleaner is added only where the surface is not coated and its suitability has been confirmed.
Q: Can it clean a shower screen?
A: Yes, with a short-pile pad and a heavier spray followed by a dry pass, because soap film needs more water and faster drying than a mirror.
Q: What is needed to quote?
A: The surfaces to be covered, pad grades, market, quantities, packaging format and branding.
