I’ve got one of the Mobi V-17’s, had it for about 4 years and it does a good job of cleaning the bike and I use mine on the car as well. Went for the battery pack version as I don’t have an outside tap.But…
I’ve had quite a few problems with mine. The main one being that it leaks water from the bottom of the water container, despite trying several different o-rings. It just never seems to get a decent seal. So word of warning if you are thinking of filling it up and taking it with you in a car somewhere to clean the bike at the end of the ride.
I’ve also had to replace the charger twice and now the connections on the hose pipe are pretty worn and will fail to connect at some point soon and the spray gun is on it’s last legs. Obviously you can get spares but it all adds to the cost. Maybe I was just unlucky and got a duff one.
Also I’m sure Mobi are ‘no more’ and just sold all their stock to CRC, I could be wrong though.
Worth checking for other threads on here as I’m sure the subject has come up before.
