Went thru two Cubes.
One SouthEastern PA, was in a pickup truck, the bay seemed much wider than 'standard' bays and the CUBE washed with no issues. SouthEastern, the Brushes bounced freely off the truck as there was plenty of space for them to freely spin beside the truck, it was a nice and wide bay. Cleaned the truck nicely.
One SouthWestern PA, the bay (my opinion) was too narrow for the equipment as those brushes spent more time in contact with the walls than the SUV. There was no room for the brushes to freely spin beside the SUV (no room). The brushes were constantly in contact with the wall and my SUV while they were in operation. This caused the SUV to be 'buffeted" and caused me to 'feel' like my SUV was damaged. Perception is reality in a carwash... even if ultimately no damage occurred. Cleaned the SUV nicely.
[[The brush/spinner motor speed is computed from the amperage draw of the motor (amperage). "Amperage Draw" determines "Brush Speed". Was the speed of the brushes accurately computed? Was the "Brush Speed" determined from the brush "Contact with my SUV" alone? Or was brush speed computed with the "Contact with my SUV" + "Contact with the Wall"?]]
