Last updated: October 2026. Kärcher is a German brand that dominates electric pressure washers in many stores. Its K-series ranges from 1,600 to 2,000 PSI. This review summarises specs from NY Garden and Of Zen and Computing and prices from Kärcher’s US site. We have not tested any Kärcher models ourselves.
What Kärcher pressure washers are available?
| Model | PSI / GPM | Type | Weight |
|---|---|---|---|
| K5 Premium | 2,000 / 1.4 | Electric, induction | 32 lb |
| K5 Power Control | 2,000 / 1.55 | Electric, induction | 32 to 34 lb |
| K3 Follow-Me | 1,800 / 1.3 | Electric, universal motor | 16 lb |
| K2 Plus | 1,600 / 1.25 | Electric | 16.5 lb |
| G2900E | 2,900 / 2.6 | Gas, 196cc | 51.8 lb |
How good is the Kärcher K5?
NY Garden rated the K5 Premium as the overall best for long-term use, with a water-cooled induction motor at 2,000 PSI and 1.4 GPM. Its weakness is that it is not built for extended heavy-duty work. Of Zen and Computing lists the K5 Power Control at 1.55 GPM with an LED display, and Kärcher’s site lists it at $399.99 to $499.99.
How good is the Kärcher K3?
The K3 Follow-Me is rated at 1,800 PSI and 1.3 GPM with a universal motor. Kärcher’s site lists it at 16 lb and $189.99 to $209.99. NY Garden notes that the wheels can stick on some terrain.
How good is the Kärcher K2 Plus?
At 1,600 PSI and 1.25 GPM, the K2 Plus weighs 16.5 lb and is for light use only, according to NY Garden.
What about the Kärcher gas washer?
The G2900E is rated at 2,900 PSI and 2.6 GPM with a 196cc engine and weighs 51.8 lb. NY Garden’s cons are no soap tank and a pull start.
What is different about Kärcher motors?
Of Zen and Computing says the induction motors in the K3 to K7 outlast universal motors by five times. That figure is the site’s own claim and we could not verify it independently, but induction motors are commonly described as quieter and more durable. Specs for the K1700 conflict between sources, at 2,125 or 1,700 PSI, so we do not rely on it.
Kärcher warranty and prices
Kärcher’s US site lists a Rapid Exchange Program rather than a warranty length, and lists K-series prices from about $139.99 to $499.99 with GPM from 1.0 to 1.5. Of Zen and Computing cites 2 years on the K1700 and K1800PS and 3 years on the K1700 Cube. Confirm terms before buying.
Kärcher pros and cons
- Pros: durable induction motors on higher K-series models, compact designs, and wide retail availability.
- Cons: lower pressure than gas, pricey K5, and limited flow.
- Best for: budget users (K1 and K2) up to regular users (K4 and K5).
Who should buy a Kärcher?

Which Kärcher should you choose?
| Need | Model | Reason |
|---|---|---|
| Cheapest start | K2 Plus | Light use only |
| Compact car washing | K3 Follow-Me | 16 lb |
| Regular home use | K5 Premium | Induction motor |
| Big jobs | G2900E | Gas power |
How do you look after a Kärcher?
Fit the inlet filter, never run the pump dry and drain the machine before freezing weather. Store the hose loosely coiled and keep the trigger gun locked when not in use. Because the K-series uses quick-connect fittings, check the O-rings occasionally for leaks. A few minutes of upkeep helps the pump last and keeps pressure steady.
Are Kärcher accessories easy to find?
Kärcher sells nozzles, surface cleaners, extension hoses and detergents through its own site and major retailers. Because parts are widely stocked, replacing a hose or wand is usually simple. Check compatibility with your K-series model before buying, since fittings differ between the K2 to K3 line and the K5 and up. Match any add-on to your machine’s flow, because low GPM units may not spin a larger surface cleaner. See our surface cleaner guide for sizing.
