When it comes to cleaning performance, the Kärcher K1700 is equipped with a TruPressure output of 1700 PSI, effective for regular household cleaning tasks. It includes three spray nozzles (15°, turbo, and 65°), allowing users to tackle different jobs with precision. The K1700’s detergent tank further enhances its cleaning capabilities by allowing users to apply soap effectively.
On the other hand, the Westinghouse surface cleaner attachment boasts a higher maximum pressure of 4400 PSI, making it an excellent choice for tough cleaning tasks on surfaces like decks and driveways. Its 16.5-inch cleaning area allows for quick coverage of large flat surfaces, making it particularly efficient for extensive cleaning jobs.
User-Friendly Features
The Kärcher K1700 is designed with user convenience in mind. It features an on/off foot switch for easy operation and a removable detergent tank, simplifying the cleaning process. The unit is also equipped with never-flat wheels, enhancing maneuverability across different terrains.
Conversely, the Westinghouse attachment utilizes a 1/4” quick-connect fitting, enabling easy switching between different attachments. Its simple design ensures that both professionals and homeowners can use it effectively, making it a user-friendly addition to any pressure washing toolkit.
Portability and Storage
In terms of portability, the Kärcher K1700 shines with its never-flat tires, allowing for easy transportation around the property. The integrated storage container keeps essential components organized when not in use, enhancing its practicality.
The Westinghouse attachment, while not a standalone unit, is lightweight and designed for easy storage.

Price Comparison
The Kärcher K1700 is currently priced at $169.99, while the Westinghouse surface cleaner attachment is priced at $89.99. This means the K1700 is about 88% more expensive than the Westinghouse attachment.

The average price over the last 90 days for the K1700 is $157.80, indicating some variability in pricing but still reflecting its value in the market. In contrast, the Westinghouse attachment has maintained a consistent price of $89.99 over the same period, making it a stable option for those looking to enhance their existing pressure washing setup.

While the K1700 requires some care for its various components, the Westinghouse tool is designed for durability and ease of use.
Which should you buy?

If you're looking for a complete electric pressure washer with versatile cleaning options suitable for various surfaces, the K1700 is an excellent choice. Its higher price reflects its comprehensive features and usability.
However, if you already own a compatible pressure washer and seek to enhance its performance, the Westinghouse surface cleaner attachment provides powerful cleaning capabilities at a lower price point. With a maximum PSI of 4400, it excels in tackling flat surfaces quickly and efficiently.
In conclusion, if you need a standalone cleaning solution, the Kärcher K1700 is the way to go. If you're looking to complement an existing setup, the Westinghouse attachment is a valuable addition.
