Overview
The K1700 is Karcher's entry electric pressure washer, rated at 1700 PSI and 1.2 GPM and CETA certified, aimed at routine cleaning of cars, driveways, siding and patios rather than heavy commercial stripping.
CETA certification means the PSI and GPM figures are independently tested rather than self-reported, which matters in a category where marketing numbers often run higher than real output. The K1700 pairs that rating with three swappable nozzles and a built-in detergent tank, positioning it as a straightforward driveway-and-car unit rather than a deck-stripping machine.
- 1700 PSI, 1.2 GPM, CETA certified
- Three nozzles: 15 degree, turbo, 65 degree
- Foot on/off switch with trigger auto-stop
- 0.5 gallon built-in detergent tank
Who it's for
Suits a homeowner who wants one washer for cars, patios, fences and siding without stepping up to a gas unit. Not the choice for stripping paint, cleaning large decks fast or any job that calls for pressure well above 1700 PSI.
Strengths and trade-offs
Drawn from this product's published specifications.
- CETA-certified PSI and GPM ratings, independently tested rather than self-reported
- Foot switch and auto-stop trigger make operation back-friendly
- Three nozzles cover both spot cleaning and wide rinsing
- Never-flat wheels roll over uneven ground
- 1.2 GPM flow is modest next to gas-powered washers
- No pressure setting beyond what each nozzle provides
Performance notes
The foot-operated on/off switch lets you start and stop the pump without bending down to the unit, and the auto-stop feature cuts the motor when the trigger is released rather than leaving the pump running under pressure. Three nozzles (15 degree, turbo and 65 degree) cover concentrated spot cleaning through to wider, gentler rinsing, and the 0.5 gallon detergent tank draws soap inline without a separate sprayer.
