Product description

Ecovacs – for Glass Surfaces with or without Frames

The Winbot cleans framed or frameless glass surfaces, larger than 50 x 50 cm (19.7” x 19.7”). It is the ideal window cleaning robot for framed and frameless windows. When operated on framed glasses, please mind a minimum frame thickness of 5 mm.

Easy Operation

The Ecovacs Winbot W850 scores with easy handling. Simply press the Start button and the Ecovacs automatically starts cleaning. After completing it independently returns to its starting point.

For Different Glass Surfaces

The Winbot W850 is equipped with air suction (fan). Therefore it can be used individually on different kind of glass surfaces. It cleans balcony windows, framed and frameless glass doors, mirrors and the like.

Please note
The Ecovacs Winbot W850 cleans horizontally mounted glass surfaces only when controlled with the remote. It could happen, that the Ecovacs cannot be operated on inclined glass surfaces. An upside-down usage (like ceiling of sunrooms) is not possible.

Washable and Reusable Microfiber-Cloth

For a thorough window cleaning the Winbot W850 uses a large Microfiber-cloth that is mounted on the underside of the window cleaning robot. Please take care of not covering the edge sensors or the squeegees with the cloth.

After window cleaning, the Microfiber-cloth can be removed from the robot. The cloth is washable and reusable. Please wash it by hand or in the washing machine by up to 30°C (no softener; no drier).

Recognizes Size and Shape of the Window

The Ecovacs Winbot W850 recognizes the size and shape of the window. Accordingly, it automatically selects the most effective cleaning path. You can also select the cleaning pattern with the remote control:


  • Cleaning mode “Z”- cleaning pattern on wide windows
  • Cleaning mode “N”- cleaning pattern on narrow windows

Requirements for Operating the Window Cleaning Robot

When applying the cleaning fluid: Less – is More. Only put a minimal amount of fluid onto the Microfiber-cloth. Otherwise there could occur streaks. There is a special cleaning fluid included in the scope of delivery.

Our Secret Hint:
You can also use water mixed with alcohol in order to achieve an equally good result. Furthermore you could use a commercial cleanser.

For a Regular Window Cleaning

The Ecovacs Winbot W850 is intended for regular cleaning of glass fronts. For use on highly contaminated glass fronts or for the first window cleaning in spring, it is necessary to do a repeated insertion. For heavily contaminated glass fronts we recommend a manual pre-cleaning.

Charge Before Each Usage

The Winbot W850 is equipped with a safety battery to avoid dropping immediately in case of a power breakdown. This safety battery has to be fully charged before each usage. Please keep in mind to switch the main button ON for charging. When the start button blinks blue, the window cleaning robot is ready.

Winbot W830 vs. Winbot W850

Der Winbot W850 ist mit einem Sicherheits-Akku ausgestattet, um im Falle eines Stromausfalls nicht sofort von der Glasfläche zu fallen. Dieser Sicherheits-Akku muss vor jedem Gebrauch vollständig aufgeladen werden. Bitte denken Sie daran, den Hauptschalter auf der Geräteunterseite auf ONzu stellen. Sobald die Start-Taste blau blinkt, ist der Ecovacs Winbot W850 einsatzbereit.

The Lesson is Clear

The Ecovacs Winbot W850 is the ideal window cleaning robot for


  • Vertical glass surfaces with or without frames
  • Different conditions like mirrors, balcony doors, etc.
  • Hardly reachable glass surfaces
  • Satin-finished, stained, glued and bright glass


This Winbot is less recommended for:


  • horizontal surfaces (only manual controlling)
  • inclined glass surfaces
  • glass surfaces with less than 50 x 50 cm

Customer Review(s)

5-year guarantee5-year guarantee

With their technical sophistication and excellent range of features, robots from myRobotcenter never fail to impress. Our robots are guaranteed to provide you with more free time and a better quality of life. Guarantee is also the key word when it comes the longevity of our products. Thanks to their sophisticated, tried and tested technology, our products have proven to be extremely reliable and free of faults. If a design fault should arise, then you can rely on a guarantee that – with many products – extends far beyond the statutory minimum.


Extension of the guarantee to 5 years

Our products come with a manufacturer's guarantee (generally 2 years). At myRobotcenter you get an even longer guarantee on many products: we extend the guarantee period to 5 years.


Complete security over many years

Our 5-year guarantee on labelled products is both a mark of quality and a very special service for you as our customer. In addition to the respective guarantee, we provide  you with all the details about the conditions of our guarantees and which services you can expect from us.


What does the guarantee cover?

The 5-year guarantee covers devices bought from us when accompanied by a receipt or another document that proves the validity of the 5-year guarantee. The 5-year guarantee ends five years after the device was purchased. The guarantee is valid for guarantee claims that occur in United Kingdom.


A guarantee claim is valid when the device purchased by you is damaged or destroyed, as a result of the following causes:

  • construction fault, calculation error, casting defect, material defect and production fault

  • direct effects of electrical energy as a result of a ground fault, short circuit, excessive increase in the current strength, electrical arc-over, formation of electrical arcs, insulation faults, excess voltage and the like.

Excluded from the guarantee is damage caused by external influences, such as a bounce flash in the circuit or fire damage. Such externally induced damages can be covered under certain circumstances by your household insurance and may include:

  • measuring, controlling and safety device failures

  • excessive pressure other than explosions

  • implosion and other effects of insufficient pressure

  • lack of water in steam boiler and other apparatus

  • bursts due to centrifugal force


Within the framework of the extended guarantee, operating errors are covered insofar as they impair the functionality of the product and do not represent a contravention of the operating instructions. For such cases we shall charge an excess of 84 GBP including VAT.


What is NOT covered by the guarantee?

  • Wear and tear, and damage to wearing parts and batteries (the battery is only covered by the manufacturer's guarantee)

  • Damage that does not impair the technical function of the device, e.g. scratches and scuffs.

  • Damage or destruction due to intentional or grossly negligent acts or omissions on the part of the purchaser or other users of the device.

  • Damage or destruction caused by improper installation/assembly, by improper repairs/adjustments, by improper, non-intended or unusual use or cleaning of the device – especially when the manufacturer’s instructions are not followed – and by operating errors.


What service do we provide in valid guarantee cases?

  1. When repair is technically and objectively possible and the costs of repair do not exceed the current value of the device (see clause 3), the device shall be repaired professionally and the costs incurred in the repair reimbursed by the guarantee.

  2. Should repair be technically or objectively impossible or uneconomical (total write-off), you shall receive a replacement device of the same kind and quality up to the amount of the current value (see clause 3). The damaged or destroyed device is returned to us and becomes our property.

  3. The current value of your device is 50% of the purchase price in the 3rd year after conclusion of purchase contract, 40% in the 4th year and 30% in the 5th year of the purchase price as stated in the receipt.


Is your device broken?

Just ask us for help. We will support you with the repair request.

  1. In the matters of a needed repair, a skilled and trained team in service and repair department from us or from the manufacturer itself, will gladly be there for you with advice and act to the side.

  2. Please take care of packing the robot carefully to avoid damage.

  3. Enclose a detailed description of the fault as well as the invoice together with the 5-year guarantee certificate.

  4. The robot must be fully postage paid at and sent to the mentioned address.

  5. Transport costs are paid by you and will not be refunded. We recommend that you keep the postage receipt.
