The short version

Eziclean Windobot S5 Pro brings spraying and quieter operation together

The Windobot S5 Pro combines automatic spraying, app control, and a noise specification among the lowest in its category. We see a sensible match for regular household care of supported glass surfaces. You still handle placement, the power connection, and moving it between windows.

Verdict

7.5/10

We would choose Windobot S5 Pro for manageable stretches of glass

For a sunroom that doubles as your reading corner, automatic spraying and the maker's relatively low sound figure make a persuasive combination. We give it a favorable overall assessment in our scores. Hand over the spray bottle, keep a hand in the routine.

Our verdict: We recommend it for regular care of supported household windows and mirrors, with an outlet nearby. For large picture windows, consider Mova N1 with its larger tank, whose higher water tank capacity better suits that job.

Worth noting Refill stops across a long stretch of glass are our sticking point, even though the tank is a typical size for this category. Avoid it if pausing to refill across a long stretch of windows is exactly what you want to escape.

Who it's for

Your frameless windows could use a regular cleaning companion

  • Households with frameless windows
  • Mirror owners seeking automatic spraying
  • Phone users comfortable with app control
  • Readers prioritizing a lower noise specification

This robotic window cleaner suits households with frameless windows and mirrors, especially if phone control already feels familiar. Think of a sunroom you want to keep presentable without spending the afternoon reaching for a spray bottle. Its comparatively low noise specification adds appeal when that same room is where you read, while placement and moving between panes remain your jobs.

Less suitable if

Skip this model if you need cleaning without an outlet, want to leave it working while you head out, or would find repeated lifting onto the glass awkward. App control does not remove the need to remain nearby, and mains power is part of every cleaning session.

Our scores explained

Where do the scores of this window cleaning robot come from?

Every model on the site is scored on the same criteria, using the same scale: its position among models with verified data for that specification. Last place earns 6.5, first place 9.6, and the rest are scored in proportion to their rank. Here is how this model's scores are calculated.

Two model counts: the rank and average include product pages on this site scored for the criterion; the calculation compares the model with all catalogue models whose specification is verified, with or without a product page. A score assigned at publication may remain without a verified specification, so the first count can sometimes be higher.

Suction pressure: 8.4/10

Eziclean Windobot S5 Pro scores 8.4/10 on this criterion. Across the 14 product pages on the site with a score for this criterion, the average is 8.1: above average, Rank 6 out of 14.

Our full methodology

Detailed analysis

You sit down in the sunroom with coffee, then notice the glass could use the afternoon you had planned for yourself. The Eziclean Windobot S5 Pro pairs automatic spraying with app control and a manufacturer's noise figure that stands out favorably in its category. For household frameless windows and mirrors, that is an appealing combination. The decision is how much spraying you can hand over, and how much moving between panes you are happy to keep.

The Windobot S5 Pro window cleaning robot puts automatic spraying to work

The spring Saturday reserved for cleaning the windows has a way of swallowing the afternoon. The Eziclean Windobot S5 Pro offers automatic spraying for that familiar household chore, bringing liquid application into the robot's routine. Less reaching for the bottle. The spray bottle gets a break; you still handle placement, refills and the move to the next pane.

Would you rather spend that time looking through the sunroom windows? We like having the robot handle spraying while you take care of placement, refills, and moving it to the next pane. That division of labor makes sense for regular window care, even though dried marks may still need attention. The dirt, cleaning solution, and cloth condition influence the finish.

The reservoir holds 50 ml, a typical tank size among window cleaning robots. Think of it as a liquid supply to monitor between panes, with refill needs depending on how dirty the glass is. It gives you a starting point for the afternoon, without telling you how much glass you can clean before returning to the sink.

Frameless glass gives the Windobot S5 Pro a clear place in the home

Frameless window compatibility is explicitly supported, and mirrors are also among the verified surfaces. That gives this robotic window cleaner a concrete role where broad glass panels and a bathroom mirror compete for attention. Choose around the glass you own. Shower glass with hard water marks should not become an assumed application simply because it is another chore you would happily hand over.

The manufacturer's suction pressure figure is 3500 Pa, around the average for window cleaning robots. For a living room picture window, that puts its advertised suction in familiar category territory. It does not establish how reliably the robot will remain attached in every situation.

Manufacturers' manuals instruct users to secure a safety tether to a fixed anchor and remain nearby, especially on an upstairs exterior window. They also advise against exterior cleaning in rain. If a rainy winter has left the view looking tired, save the exterior work for a dry day.

A Windobot S5 Pro window cleaning robot review starts near an outlet

The backyard sliding door may be easy to reach, but the nearest usable outlet still matters. Before placing the robot on the glass, work out where the power connection will run and how you will manage it when moving to the next window. The cord comes along. A cleaning session across the room involves more than carrying the appliance over.

Its electrical power specification is 72 W. That describes its electrical demand during operation; it cannot predict how long cleaning will take or how the glass will look afterward. For your afternoon plans, the amount and condition of the glass matter more than that figure.

What happens if the power cuts out with the robot upstairs? The UPS backup battery is intended to maintain adhesion temporarily while you retrieve it. Cleaning still requires mains power, and the backup is no guarantee against a fall. Keep retrieval practical before starting, especially where reaching the glass would require a stepladder.

Windobot S5 Pro pairs a low noise specification with app control

A robot working on the living room glass shares the room with whatever you are doing. The manufacturer's noise figure of 58 dB places this model among the quietest window cleaning robots by their stated specifications. That makes it an appealing candidate if louder household equipment wears on you. Beside a reading chair, that lower sound specification is a useful reason to consider it, without expecting silence.

Control comes through an app. If your phone already handles familiar household tasks, that approach should fit your habits. Particular scheduling or remote-access functions are not established by app control alone. The appeal here is straightforward: operating the cleaner through your phone while staying nearby.

At 1,35 kg, the robot needs lifting onto each pane and taking down again, so a room full of separate windows still gives your arms a job. Your arms remain on duty. It earns a favorable overall assessment in our scores. We would consider the repeated lifting alongside the convenience of spraying and phone control, particularly if your home has many separate panes.

A 50 ml tank shapes the choice for large picture windows

What holds us back is water tank capacity when your cleaning plans stretch across extensive glass. A typical reservoir is less appealing when you want to work through a whole sunroom with fewer refill stops. How much time at the sink are you willing to build into that afternoon?

Lubluelu CHYW201 for greater tank capacity has higher water tank capacity at 160 ml. That means more liquid available between refills, directly addressing the Windobot S5 Pro's weakest criterion. Lubluelu CHYW201 also has a higher suction pressure value. Lubluelu CHYW201 is better rated overall, making it a clear alternative when the reservoir drives your choice.

Mova N1 has higher water tank capacity at 120 ml, making it better suited to large picture windows thanks to a larger tank. More liquid is useful across broad panes, though it does not promise a particular cleaning area. Mova N1 also has a higher suction pressure value. Mova N1 is better rated overall.

Frequently asked questions

Your questions about the Windobot S5 Pro before ordering

Can the Windobot S5 Pro clean frameless windows and mirrors?

Yes. Frameless window compatibility and mirrors are explicitly supported for household use. That gives it a useful role around those surfaces. Do not assume the same support extends to tile or shower enclosures simply because those also need cleaning.

What does the Windobot S5 Pro backup battery do?

The UPS backup battery is intended to keep the robot attached temporarily during a power outage so you can retrieve it. It does not power cleaning away from an outlet or guarantee against a fall. Keep the safety tether secured and stay nearby.

How quiet is this robotic window cleaner?

The manufacturer's noise figure is 58 dB, among the lowest sound specifications for window cleaning robots. That makes it worth considering for a living room or reading space, though you should still expect to hear an appliance working nearby.

What should I confirm before ordering the Windobot S5 Pro?

Ask the retailer whether a safety tether and extension cord are included, which replacement cloths fit, and how to obtain them. Check the warranty, return policy, and customer support arrangements at the same time, so maintenance and help are straightforward later.
