Quick answer
Yes. Vitrela works on smooth, flat glass inside and out: 5600 Pa suction holds it on, an ultrasonic spray wets the glass, and spinning microfibre pads wipe it while edge sensors steer it around the pane. It isn't made for frosted or textured glass or very small panes. And with a 30-day money-back guarantee, you can try it on your own windows.

How Vitrela cleans a window

Vitrela works like a careful pair of hands on the glass. Its motor creates 5600 Pa of suction so the robot sticks flat to the pane. The ultrasonic sprayer mists a fine layer of liquid ahead of it, and two rotating microfibre pads wipe the moisture and grime away as it moves.
Edge sensors detect the frame so Vitrela can change direction and work its way across the whole pane. You simply place it, press start, and let it do the wiping while you stay safely on the floor inside.
Before and after: what to expect

On everyday dust, fingerprints, rain spots and light salt or pollen film, Vitrela leaves glass clear and bright. Heavily caked grime (years of build-up, paint flecks or hardened mineral deposits) may need a quick pre-clean or a second pass first.
Think of it as the robot doing the tiring, repetitive wiping you used to do by hand or from a ladder, so routine window cleaning becomes something you do often rather than dread.
Safe for you
Three layers of safety. Zero ladders.
- 1
5600 Pa suction
Holds firmly on vertical and sloping glass the whole time.
- 2
Backup battery + alarm
If the power cuts out, it keeps holding and beeps to warn you.
- 3
4 m safety rope
Tied off indoors, so it can never drop away from the window.
Where Vitrela shines, and where it isn't the right tool
Being clear about this up front saves you a wasted purchase. If your windows are in the left column below, Vitrela is a good fit. If most are in the right column, a robot isn't the best choice for you.
| Window type | Good fit? | Why |
|---|---|---|
| Large sliding glass doors | Yes | Big flat panes are ideal for the robot to work across |
| Picture and fixed windows | Yes | Smooth, flat glass with a clear frame edge |
| Outside of windows you can reach from inside | Yes | Clean outside glass without leaning out or a ladder |
| Balcony and apartment glass | Yes | With the safety rope secured inside |
| Frosted or textured glass | No | Suction needs a smooth surface |
| Very small panes | No | Too little room for the robot to move |
Getting a streak-free finish
These simple habits make the biggest difference to the finish. Our step-by-step setup guide walks you through your first clean.
- Start with clean, dry microfibre pads, and wash them after each session.
- Use only a light amount of liquid in the tank; too much is the most common cause of streaks.
- Brush off loose dirt, cobwebs and bird droppings first on very dirty outside glass.
- Run a second pass on heavily soiled panes rather than adding more liquid.
- Clean on a cool, overcast part of the day so the glass doesn't dry before the pads finish.
Built-in safety while it works
Vitrela is powered by cable while it cleans. If the power is interrupted, a backup battery keeps it holding on and sounds an alarm so you know to bring it in. The 4 m safety rope is attached to something solid inside as a second layer of protection.
That means you can clean the outside of windows without leaning out or climbing a ladder, as long as you can place and retrieve the robot comfortably from inside.

Robot vs doing it yourself vs paying a cleaner
Hand-cleaning outside windows usually means a ladder, buckets and an afternoon. A professional window cleaner in Australia typically charges somewhere around A$150 to A$300 per visit for a house (a rough estimate; prices vary by city and home). Vitrela is a one-off A$199.99, so for many homes it pays for itself within one or two cleans, and you can clean whenever you like.
Common questions
Do window cleaning robots really work?
Yes, on the right glass. Robots like Vitrela do a very good job of routine cleaning on smooth, flat windows and glass doors. They're less suited to frosted glass, tiny panes or glass covered in years of hardened build-up.
Will Vitrela fall off the window?
Vitrela holds on with 5600 Pa suction. If power cuts out, a backup battery keeps it attached and sounds an alarm, and the 4 m safety rope tied inside is a second layer of protection.
Does Vitrela leave streaks?
Streaks usually come from dirty pads or too much liquid. Start with clean pads and a light fill, and do a second pass on very dirty glass instead of adding more liquid.
Can Vitrela clean the outside of my windows?
Yes. Place it on the outside of the glass from inside your home, with the safety rope secured inside. Only do this where you can reach and retrieve it comfortably without leaning out.
Does it work on double-glazed or tinted windows?
It works on the outer surface of smooth, flat glass, including most double-glazed panes. For tinted film, check the film maker's care advice first.
How do I know it will work on my windows?
Check the table above: smooth, flat glass of a reasonable size is a good fit. You also have a 30-day money-back guarantee, so you can try it at home.
Do I need to supervise it?
Stay nearby while it cleans, especially on outside glass, so you can respond to the alarm and move it to the next pane.
