Mobi’s distinctive blue-tanked washers have been around for a while, but while the spec looks good actual execution is disappointing. Being able to run the unit off the in-built battery pack or your 12V car plug is useful for 24-hour races/backyard use when the car might not be close. The washing action is okay in jet or spray modes, but it’s not powerful enough to get a frame properly clean without using a cleaning agent and/or rag.
The hose and spray gun use a bayonet attachment, which is secure enough, but the fixed connection is vulnerable to knocks. The 17-litre tank is enough to wash three bikes if you’re quick and can be removed for easier carrying. The small wheels struggle with trail centre car parks or grassy fields when full, and the shoulder strap has a habit of falling off.
You still have to take the whole bottom half (rather than a removable battery) inside for charging and the mains jack port is exposed to accidental spray and filth. Our sample leaked all over the workshop floor while not in use which negates the whole idea of taking a full tank with you.
