Review on 🚿 SPTA Cordless Pump Sprayer, Cordless Foam Cannon - 8.4V 1.8L - Full Function Cordless Foam Sprayer for Car Washing and Cleaning by Steve Beaumont

Has a relatively small volume if you have an SUV. The battery is empty very quickly. In my case, it survived 2 cycles (prewash and wash) in the first 3 washes. On my fourth wash, the battery even failed during a pre-wash. That means a fully charged battery won't last 10 minutes (my pre-wash usually takes 5-7 minutes, but I'll give it a generous rating here). Also, on my fourth wash, the suds felt more like a drip than an even suds distribution. I wouldn't use it for the fifth wash. Now it's junk for me. I do not recommend.
