Which power washer surface cleaner is good to buy?

I researched the best power washer surface cleaner as i’ve been doing more driveway, sidewalk, and patio cleaning and wanted a faster way to get professional-looking results. i have been experiencing uneven cleaning, streaks, and spending too much time using a standard pressure washer wand on large concrete surfaces. i went through reviews from trusted sources like reddit, pressure washing resource, and consumer reports and after comparing many options these two kept coming up as the top choices:

JANZ 30 Pressure Washer Surface Cleaner

Simpson Pressure Washer Surface Cleaner

https://www.amazon.com/Simpson-Cleaning-CM61248-S-Machine-Pressure/dp/B09RQYYMRH/

however, i am having trouble deciding which one would be better for me and i would love to get your expert advice and hoping maybe some experienced pressure washing professionals on this forum can also share their advice. i usually clean residential driveways and sidewalks and need something durable, efficient, and capable of handling regular use. Any suggestions or advice would be appreciated.
Thanks in advance
