Karcher K4 Power Control Flex Home Pressure Washer

Kärcher K 4 Power Control Flex Home — Proper Cleaning Power Without the Guesswork

• Max. 130 bar pressure for patios, cars, garden furniture and outdoor cleaning.

• Includes Home Kit with T 5 Surface Cleaner and Stone & Façade Cleaner

• 8 m PremiumFlex high-pressure hose for easier movement around the job

• Power Control trigger gun and Vario Power spray lance for surface-by-surface cleaning

• Plug ’n’ Clean detergent system, Quick Connect fittings and water-cooled motor

Some pressure washers are powerful. Some are easy to use. The Kärcher K 4 Power Control Flex Home is both.

Built for the jobs most homes actually face — dirty patios, weathered garden furniture, muddy bikes, small cars, paths, stonework and outdoor tools — the K 4 gives you the confidence to clean properly without feeling like you’re about to strip the surface by mistake.

It delivers up to 130 bar of pressure with a maximum 420 litres per hour flow rate, giving you the punch needed for moderate outdoor dirt while still keeping control firmly in your hands.

This is the Home version, which means it comes with the kit most people end up needing anyway: the T 5 Surface Cleaner for larger flat areas and 1 litre of Stone & Façade Cleaner for patios, paths and exterior surfaces. In plain English, it is the better choice if your main reason for buying a pressure washer is to bring the patio, driveway or garden area back to life.

Take the Pressure Off Choosing the Right Pressure

The clever part of the K 4 Power Control Flex Home is not just the cleaning force — it is how easy Kärcher makes that force to manage.

The Vario Power spray lance lets you adjust the pressure by simply turning the lance, while the G 160 Q Power Control trigger gun helps you check the selected pressure level as you work. That means you can move from a tougher surface like paving to a more delicate surface like car paintwork or garden furniture with far more confidence.

For extra guidance, the Kärcher Home & Garden app includes an application consultant with tips for different cleaning tasks, helping you choose the right setting for the job rather than guessing and hoping.

The Home Kit Makes the Difference

If you have ever cleaned a patio with only a standard lance, you will know the pattern: splash everywhere, uneven cleaning lines, and a job that takes longer than expected.

The included T 5 Surface Cleaner is designed to make large outdoor areas quicker, cleaner and more even. It helps reduce splashback and keeps the cleaning action focused, making it ideal for patios, paving, paths and areas around the home.

The included Stone & Façade Cleaner gives you a proper detergent option straight out of the box, so you are not buying the machine and immediately discovering you need more accessories before you can tackle the real job.

PremiumFlex Hose for Easier Handling

Pressure washer hoses can be frustrating when they are stiff, awkward or constantly fighting you. The K 4 Power Control Flex Home includes an 8 m PremiumFlex high-pressure hose, giving you better reach around the car, patio or garden without constantly dragging the machine behind you.

The Quick Connect system makes attaching and removing the hose faster and easier, while the telescopic handle helps when moving the unit in and out of storage.

Built for Regular Home and Garden Cleaning

The K 4 sits in a sweet spot for many households. It is more capable than a small occasional-use washer, but still practical enough for normal home use.

The water-cooled motor is designed for durability, while the integrated water filter helps protect the pump from dirt particles in the water supply.

Use it for cleaning small cars, motorbikes, scooters, bikes, e-bikes, garden machinery, outdoor tools, patios, paths, garden furniture and general areas around the home.

Why Buy the Kärcher K 4 Power Control Flex Home?

Choose the K 4 Power Control Flex Home if you want a pressure washer that feels like a proper upgrade: stronger, smarter and better equipped for real outdoor cleaning.

It has the power for the dirty jobs, the control for mixed surfaces, and the Home Kit accessories that make patio cleaning far more practical. For most homes, this is the Kärcher pressure washer that makes sense when you want more than a basic machine but do not need to jump all the way to a heavy-duty professional setup.
