TL;DR Universal (brush) motor; CSA listed per Amazon specs — listing number not independently verified in CSA Group database (merchant claim). Label spec 1,800 PSI / 1.45 GPM; no community meter test. Kärcher proprietary quick-connect — standard foam cannons need an adapter; 1.45 GPM is adequate. LED pressure-display trigger gun, DirtBlaster wand, 26 ft hose. Bimodal Amazon rating (47% five-star, 26% one-star): pump pressure failures and garden hose connector issues dominate one-star reviews. No active CPSC recall.
What it is and how it performs
Corded 120V universal-motor pressure washer. The LED Power Control trigger gun displays current pressure for on-the-fly adjustment on paint, glass, and tires. Includes a Vario Power twist-adjust wand and DirtBlaster concentrated-jet wand — not a traditional 5-nozzle set. Foam cannons need a Kärcher-to-1/4" QC adapter; 1.45 GPM is adequate once connected. The 26 ft hose covers all four panels without repositioning.
Safety
No CPSC recall on file. Dispose via municipal e-waste — corded electric, no lithium battery.
Frequently asked questions
Does the Kärcher K3 Power Control work with a foam cannon?▾
Yes, with an adapter. The K3 uses Kärcher's proprietary Quick Connect system — standard 1/4" QC foam cannons require a Kärcher-to-1/4" QC adapter to connect. These adapters are widely available and community-confirmed compatible. The rated 1.45 GPM flow is above the 1.4 GPM threshold for thick foam generation, so foam output is adequate once the adapter is in place.
Is the Kärcher K3 Power Control UL or ETL certified?▾
No UL or ETL listing was found in the UL Product iQ or ETL/Intertek certification databases. Amazon product specs state 'Specification Met: CSA' — CSA is an OSHA-recognized Nationally Recognized Testing Laboratory (NRTL) equivalent to UL and ETL. However, the specific listing number was not independently verified in the CSA Group public database at the time of this review, so this remains a merchant claim rather than a database-confirmed NRTL listing.
What is the actual cleaning output of the Kärcher K3 Power Control?▾
The label specifies 1800 PSI rated and 1.45 GPM, yielding approximately 2,610 cleaning units as a label-derived figure. No community PSI/GPM meter tests were found to confirm or contradict the rated spec. Amazon reviews indicate the K3 handles car washing and light exterior cleaning effectively but is not suited for heavy-duty tasks like stripping old deck stain or cleaning concrete.
Is there an active CPSC recall on the Kärcher K3 Power Control?▾
No. The CPSC recall database was searched on May 17, 2026, and no active recall was found for the Kärcher K3 Power Control pressure washer.
Is the Kärcher K3 motor induction or universal?▾
Universal (brush) motor. The manufacturer's own feature bullets confirm this: 'highly reliable universal motor and non-corrosive N-COR pump.' Kärcher's premium K-series models (K4, K5) use induction motors — the K3 tier uses a universal motor, which is standard for this price class and PSI range.

It's a keeper!
This little pressure washer is a champion, weighing in at only 12 pounds, it sure gets the job done. We used it to clean a 36 foot fiberglass sailboat ⛵️ and it performed just fine.For those interested in purchasing a new Karcher K3, the instructions mention using a water filter between the water supply and the water pump intake. Apparently, dirt and heavy mineralized water is a certain early death for the pressure washer's water pump. So, we used a flexible hose connector, a water pressure regulator, a RV water filter, and a hard (not a flexible-expanding) garden hose to connect to the pressure washer and it did just great.After finishing the sailboat ⛵️ we purchased several K3 compatible accessories for getting work done at home, like a 15 meter hose, hose connector, foam cannon, extension wands, and spray fittings and some different nozzles for cleaning automobiles, sheet metal gutters, and concrete.My wife really enjoyed using the pressure washer, for PPE, we both wore eye protection and gloves.If you take of your stuff, this little champ should last many years. The K3 is manufactured in Germany.
