  • Written by: Amanda Myers

Editor rating: 4.6/5

We reviewed the Karcher K5 Premium 2000 PSI 1.5 GPM Electric Pressure Power Washer and we based our rating on these criteria:

  • easy to assemble
  • ease of use
  • safeness
  • cleaning ability
  • and durability

This pressure washer has the least number of reviews, but more than 80% of the ratings are at either 4 or 5-star rating which goes to show that most of the buyers are satisfied with the unit. It appears that the unit is more suited for light-duty use at home since it is fairly easy to assemble, it is lightweight and small which makes it easy to store, the noise output is relatively quiet. Its cleaning ability is best for cleaning the front walk, driveway, removing moss, front porch, concrete, siding, patio, benches, pool deck, bricks, boat stains, and car wash.

Although it is the most expensive pressure washer we reviewed, we gave it a rating of 4.6 out of 5 stars because it has a patented water-cooled induction motor and N-COR pump. These components were specifically designed to increase the life of the motor by up to 5x without needing maintenance. Most importantly, there are very few reports of leaking from the buyers, unlike the other pressure washers we reviewed. Read on!
