Find the right fit
Not sure which one fits your windows?
Measure one pane and answer a few quick questions. We'll narrow down which models are worth considering.
Before you spend £250–£550
Are robot window cleaners worth it?
They can save a lot of repetitive wiping on suitable windows, but they still need setup, pad cleaning and safe placement. Their strongest use case is repeated cleaning on larger or awkward panes that you can still reach safely to place and retrieve the robot.
What they automate
Movement and repeated cleaning passes over suitable flat, smooth glass.
What you still do
Prepare the pads, add cleaning fluid where instructed, position the robot, secure it and retrieve it.
When to skip one
Very small panes, unusual surfaces, unsafe access or windows outside the model’s instructions can make one a poor fit.
Safety comes first: never lean out, climb unsafely or bypass a supplied tether or anchoring system.

Buyer questions
What to know before choosing a robot cleaner for your windows
Measure one pane
Measure the glass inside its frame. WINBOT mini 2 starts at 25 × 25 cm; W2S models need at least 30 × 40 cm and HOBOT S7 Pro 50 × 50 cm.
Plan power and access
Mains-powered models need a suitable socket throughout the clean. Station-battery models offer another setup, but still need safe station and tether placement.
Check the glass
The comparison covers framed and frameless flat glass. Do not assume the same answer for curved, textured or unusual surfaces.
Expect some manual work
You still need to prepare and care for the pads, apply cleaning fluid as instructed and deal with any finishing work.
Robot window cleaner FAQs
Do robot window cleaners actually work?
They automate repeated passes over suitable flat glass, but still need setup, safe placement, retrieval and clean pads. Results depend on the window, the model and how it is used.
Are robot window cleaners worth the money?
They may be useful if you have several suitable panes or awkward windows you can still access safely. They are less compelling for a few small panes or surfaces outside the manufacturer’s instructions.
Can robot window cleaners clean outside windows?
Some models have explicit manufacturer information for outside use. Safe placement, retrieval and tethering still matter; where the source is not clear, Averquo leaves the answer unconfirmed.
Do robot window cleaners work on frameless glass?
The models covered here list framed and frameless support, but you should confirm the glass is flat, smooth and within the model’s current instructions.
Can a robot window cleaner fall off?
Loss of suction, power or incorrect use can create a risk. Always use every supplied tether or anchoring system and follow the current manufacturer instructions.
Do they need to stay plugged in?
WINBOT mini 2, W2S Pro and HOBOT S7 Pro need mains power while cleaning. The two W2S Omni models have station-battery operation recorded in the current product information.
Which ECOVACS WINBOT suits smaller windows?
WINBOT mini 2 has the smallest stated minimum pane in this comparison at 25 × 25 cm. Measure one pane and check the current manufacturer instructions before buying.
What is the difference between WINBOT models?
The main differences in our current data are minimum pane size, mains or station power, checked price, outside-use information and cleaning features.
Do I still need to clean or replace the pads?
Yes. A robot reduces wiping, but its pads still need care according to the manufacturer instructions.
Can a robot replace a traditional window cleaner?
Not in every situation. It can handle suitable accessible glass, but unusual surfaces, unsafe access, finishing work and windows outside its instructions may still need another approach.
