CAT Pumps Pressure Washer Attachments Editorial Review
The CAT Pressure Washer Pump Assembly is receiving commendations for its performance and quality. Many customers express satisfaction, noting that it represents a significant upgrade over previous models they have used, particularly when comparing it to the Comet pump. Users appreciate the durability and reliability of this pump, mentioning that it has performed well over extended periods, including heavy usage over three years without any reported issues. An additional highlight is the pump's capability of delivering three different pressure settings, catering well to a variety of cleaning tasks. However, potential buyers should be aware of the pump’s built-in soap injector feature, which isn’t useful for every user. Those who prefer not to use the soap injector need to take precautionary measures, like using a rubber vacuum cap, to prevent air from entering the water stream. This might be an inconvenience for some but is certainly manageable. While overall remarks regarding the performance are highly positive, one common desire among users is the inclusion of a pressure gauge, which they feel would enhance usability by allowing for better monitoring of performance. In summary, the CAT Pressure Washer Pump Assembly is highly regarded for its robust Construction, powerful performance, and adaptability, making it a worthwhile investment for anyone seeking a high-quality pump. **
