Kärcher K4 Classic Home High Pressure Washer vs Kärcher K5 Classic Home High Pressure Washer

Pros

• + Water-cooled induction motor - the K-range dividing line that decides how many summers a washer lasts
• + T 5 surface cleaner included, which is what makes driveway and patio work quick and streak-free
• + 130 bar and 420 L/h is the right balance for pavers, cars and render on a suburban block
• + Stone and facade cleaner, dirt blaster and spray lance all in the box
• + Roughly A$55 cheaper than the Power Control Home Kit it replaces

Cons

• − Amazon Global Store import from the UK - arrives on a UK plug and carries no Kärcher Australia warranty
• − No hose reel, and the hose is 6m rather than the 9m on the Power Control kit
• − No Power Control gun, so pressure is set at the lance rather than read off an LED
• − Wants a strong tap to reach full flow, like every K-series machine

Pros

• + Full K5 power - 145 bar / 2,100 PSI and 500 l/h flow
• + Home kit bundles a T-series patio surface cleaner
• + Water-cooled 2,100W motor built for frequent use
• + Cheaper than the Power Control and Premium K5 variants

Cons

• − No LED Power Control gun (set pressure at the lance)
• − No built-in hose reel (that's the K5 Premium)
• − Heavy at around 12kg
