This site tracks two product families that share a word and nothing else: home blood pressure monitors and pressure washers. The buying failures are different, but the reading failures are identical, because both sets of listings are populated by the…
Buying a product that is no longer in production is sometimes the best decision available and sometimes a slow mistake. The difference is not the age of the model. It is whether the things that wear out are still purchasable,…
Power is the part of a purchase that keeps happening after the purchase. A blood pressure monitor used twice a day is a small machine that runs a pump against an arm several hundred times a year, and it does…
The word lifetime appears on six listings in this catalog. On none of them does it describe the product warranty. That is not an accusation of dishonesty, because in every case the sentence is technically accurate. It is a lesson…
Start with a plain statement about this catalog: none of the 321 products tracked on The Pressure Experts is a renewed, refurbished or open box listing. Every one is sold as new. That is worth saying out loud, because the…
There is a field on these listings called “what is in the box”. It exists on 303 of the 321 products tracked here, and it is empty on every single one of them. Three hundred and three fields, no contents.…
A brand name tells you who put the sticker on. The model number tells you what the thing is. On this catalog the gap between those two is wide enough that a buyer who searches on the brand and a…
A star average is the most read number on any listing and the least examined. Two figures sit side by side, the average and the count, and almost everyone reads the first and ignores the second. On this catalog the…
Three words turn up constantly on home blood pressure monitor listings, and they are treated as interchangeable by the people writing the copy. They are not. Registration, clearance and validation describe three different things, and only one of them is…
A product listing looks authoritative. It has a table, the table has field names, and the field names sound like engineering. That table is mostly machine populated, and on this catalog it is wrong often enough that a buyer needs…
A pressure washer out of the box is a pump, a hose, a gun and a handful of tips. Most of the difference between an even result and a striped one comes from what gets fitted to the end of…
Pressure washers are seasonal tools, and most of them fail during the months they are not being used. Water left inside a pump expands when it freezes and cracks the housing, seals dry out, fuel turns to varnish, and hoses…
A corded pressure washer is one of the highest continuous electrical loads most households will plug into an outdoor receptacle, and it is being operated by someone standing in water. That combination is why the electrical section of a pressure…
Most of the cleaning a pressure washer appears to do is done by chemistry and dwell time, not by pressure. Detergent breaks the bond between the soil and the surface, then the jet removes what is already loose. Operators who…
A pressure washer does not make water. It takes whatever the hose bib delivers and raises the pressure of it. That means the GPM figure printed on the box is not a promise the machine makes, it is a demand…
Pressure washer manuals devote more space to warnings than to operation, and the reason is that the equipment does not look as dangerous as it is. A garden hose feels harmless. A machine producing two thousand pounds per square inch…
There is no universal chart of correct pressures. What exists is a set of pressures and nozzle angles that manufacturers commonly specify for a given material, plus a much shorter list of things that are widely warned against. Both are…
The nozzle is the only part of a pressure washer that decides what happens to the surface. The pump sets what is available. The tip on the end of the wand decides how that energy arrives: spread across a wide…
The choice between an electric and a gas pressure washer is usually framed as a power question. It is more accurately a flow question, a maintenance question, and above all a ventilation question. One of those three has consequences that…
Pressure washer listings are sold on one number. The number is PSI, it is printed in the largest type on the box, and it is the least complete way to describe what a machine will do. Cleaning is work, and…
