Just used it for the first time. Actually kind of amazing. Four little spray jets come out the end straight into the brush, which is also spinning b/c of water jets. So for bikes, this is perfect--no direct spray is hitting your hubs or headset. Super quick cleaning of those hubs as well, in between the spokes, along the rim, etc. Personally, I'd like to see some kind of soap dispenser attachment, but this thing is so surprisingly useful, I'll stop my quibbling there. Looks to be very well made and will stand up to some abuse.
