About Window Robot Guide
Window Robot Guide exists because most window robot reviews are spec-sheet summaries with a verdict attached. They describe what the manufacturer says. They do not test what the manufacturer doesn’t say.
This site tests what the manufacturer doesn’t say.
Why This Site Exists
Window cleaning robots sit in a specific category of home appliance where buyer anxiety is high, testing is rarely done, and the gap between marketing claims and real-world performance is large enough to drive a significant return rate. The average buyer reads three to five reviews before purchasing a $200–$500 robot. Most of those reviews contain no original measured data.
That gap is why Window Robot Guide was built.
Three questions drive every review on this site. First: does this robot actually clean the glass, or does it redistribute what’s already there? Second: under which conditions does the manufacturer’s performance claim stop being true? Third: what does this robot actually cost to own, when you factor in pads, solution, and the time it takes to manage them?
The third question is the one no competitor answers. The Pad Tax — the annual cost of pad replacement, solution consumption, and pad-management labor — runs $55–$90 for most households. That is a meaningful fraction of a $200 robot’s purchase price, recurring every year. No brand puts that number on the box. This site calculates it for every robot reviewed.
About Maya Chen
Maya Chen is the tester, writer, and reviewer behind every post on this site. She is not a tech journalist who borrowed a product for a week. She tests each robot for a minimum of 14 days and 20 cleaning cycles before writing a word of verdict.
Her methodology is documented in full on the How We Test page. The short version: six standard tests, three solution types, six window configurations, timing to the second, and Corner Residual measured with a ruler at all four corners of a standard 36-by-48-inch window.
She developed three testing concepts that appear nowhere else in this category: the Streak Index (a robot’s aggregate streak rate across three solution types), the Corner Residual benchmark (the uncleaned border remaining after a full cycle), and the Pad Tax calculation (the real annual ownership cost). These concepts exist because generic review language — ‘cleans well,’ ‘some streaking on dirty glass’ — does not give a buyer enough information to make a good decision.
Maya Chen tests window cleaning robots the way most buyers never have the chance to — across multiple window types, over weeks of repeated use, tracking suction consistency, path efficiency, streak rates, and what actually happens to a robot when it meets a window frame it doesn’t expect. At Window Robot Guide, every number in a review is a measured number. Every limitation is one she found before you did. Her reviews are written for people who want clean windows, not a second box of returns.
What This Site Is
- An independent review site covering window cleaning robots only
- Funded through affiliate commissions — primarily Amazon Associates
- Built around original measured data, not manufacturer-supplied specifications
- Committed to documenting limitations as clearly as strengths
What This Site Is Not
- A general smart home or cleaning appliance site
- A site that receives payment for positive coverage
- A site that rounds numbers when precise measurements are available
On Affiliate Relationships
This site earns commissions through affiliate links, primarily Amazon Associates. When you purchase a robot through a link on this site, a small percentage of the sale goes to Window Robot Guide at no additional cost to you.
Affiliate relationships do not influence test results, measured data, or verdicts. The WINBOT MINI2’s Corner Residual is 0.4 inches on a standard double-hung window regardless of whether the affiliate link is clicked. The Pad Tax calculation is the same whether you buy through this site or walk into a store. The limitations documented in a review are limitations that were found in testing, not disclosed by the manufacturer.
If a product performs poorly in testing, the review says so. The site’s long-term credibility depends entirely on that not changing.

For corrections to published data: corrections are taken seriously. If a measurement is wrong or a product has been updated in a way that changes a verdict, the review is updated and the change is logged.
