On-board nozzle storage, 35-foot hose, and easy Home Depot returns make it the low-hassle everyday choice.
PSI vs flow rate (the real spec)
Stated PSI vs measured PSI at trigger: Ryobi 2300/2150, Sun Joe 2030/1850, Kärcher 2000/2050 (matched), DeWalt 2400/2280, Greenworks Pro 2300/2200. Most washers' stated PSI is 5-10% higher than measured-at-trigger reality. Kärcher is the most honest spec.
GPM flow rate (matters more than PSI for cleaning speed): Ryobi 1.2 GPM, Sun Joe 1.76 GPM, Kärcher 1.4 GPM, DeWalt 1.1 GPM, Greenworks Pro 1.2 GPM. Sun Joe wins on flow despite lower PSI — flow + PSI together determine 'cleaning units' (CU = PSI × GPM).
Cleaning Units (real performance): Sun Joe 3,260 CU, Kärcher 2,870, Greenworks 2,640, Ryobi 2,580, DeWalt 2,510. Sun Joe wins on real-world cleaning despite lowest stated PSI.
Hose flexibility and ergonomics
Hose flexibility (cold weather kink resistance): Kärcher best (rubber hose, no kinking at 40°F), Sun Joe second, Ryobi third, DeWalt and Greenworks tied behind (plastic hoses kink in cold). The Kärcher rubber hose alone makes spring cleaning much less frustrating.
Trigger gun comfort over 30 min use: Kärcher and DeWalt have grippy padded triggers. Ryobi, Sun Joe, Greenworks have hard plastic triggers — hand fatigue noticeable after 30 min. Aftermarket trigger guns ($30-50) solve this.
Storage hose reel: Sun Joe and Kärcher have built-in reels. Ryobi, DeWalt, Greenworks: hose just dangles — kinks during storage.
Freeze survival
Stored outside through 3 freeze cycles (zone 6a winter): Kärcher K5 no damage (proper drain design). Sun Joe SPX3000 cracked pump housing on second freeze. Ryobi RY142300 fine. DeWalt DWPW2400 fine. Greenworks Pro fine.
Sun Joe is the only one with this freeze vulnerability — drain it completely after each use if you store it outside. Or store it inside. The damage is irrecoverable.
