Who runs Espresso Den
Cord Edge is an independent review site covering stick vacuums & electric brooms, founded by David King. The site researches, compares, and recommends products from published evidence. The goal is simple: help buyers pick the right one for their needs without wading through spec sheets, sponsored content, or conflicting opinions.
The site currently covers 37 stick vacuums & electric brooms across 7 categories, with 11 head-to-head comparisons and multiple buying guides. Every recommendation comes from the same research process, applied consistently across every product reviewed.
About the Founder
I built Cord Edge to create the detailed, unbiased stick vacuums & electric broom comparison resource I wished existed. My background is aerospace engineering management at Rolls-Royce, overseeing the build and assembly of complete jet engine sections for Airbus and Boeing aircraft, where no decision was made without extensive data analysis. I apply that same data-driven approach here: every recommendation is backed by structured analysis of real customer experiences, technical specifications, and competitive benchmarks.
How Every Product Is Researched
These are the steps this site actually ran, with this site's own numbers in them. Nothing here describes work we did not do.
- Owner reviews, read and kept. Every listing's customer reviews are read and the ones carrying information are kept. Across this site that is 353 owner-review citations, each holding between 8 and 38 reviews, a median of 13. We publish what we kept rather than a number for what Amazon holds.
- Published evidence, named on the page. Every factual claim traces to a published source, and each page lists the sources it used at the foot of the page: 1,172 distinct sources on this site, drawn from 108 publications and 351 owner discussion threads. Where owner reports contradict a manufacturer's figure the gap is named, because it is usually the most useful thing on the page.
- Competitive context. Nothing is judged on its own. 25 stick vacuums & electric brooms get a page each, 11 head to head comparisons argue a single pair, and 7 ranked lists put each machine against the alternatives a buyer is actually choosing between at the same money.
- What we do not do. We have not had any of these stick vacuums & electric brooms on a bench. There is no testing of our own, no measurement we took, no manufacturer samples, and no price or stock figure on any page. Where the public record is thin, the page says so instead of filling the gap.
Editorial Independence
Cord Edge earns commissions through the Amazon Associates program. When you click an affiliate link and make a qualifying purchase, a small commission is received at no cost to you. This is the sole revenue source.
Affiliate commissions do not influence ratings, rankings, or recommendations. Less expensive alternatives are regularly recommended over premium options when the value proposition is stronger. Every review includes genuine limitations — reviews without meaningful cons read as sponsored content, and those are not published.
Sponsored placements, paid reviews, or manufacturer samples are not accepted. No brand has editorial input into the content.
Standards
- No fake urgency. Countdown timers, "only 3 left" warnings, or pressure tactics are never used. These are considered purchases, and that is respected.
- Real cons in every review. If a product has a design compromise, a reliability pattern owners keep reporting, or an annoyance that shows up daily, it gets said. The presence of honest criticism is itself a trust signal.
- Visible methodology. Every review links back to this page. The research process is the same for every product, with no special treatment for the expensive ones.
- No prices, no stock claims. We publish neither. A price read at build time is wrong by the time you read it, so every page sends you to the listing to see the number for yourself.
