A Liquidator does help saving time but isnt perfect for everything.
Also as for Unger, they could really make better tools for being the global market leader…
Heck why for example does the ErgoTec T-Bar have water welves and the more expensive Premium Ninja one doesnt?
Also the Ninja leaves quite a bit of detailing left behind too.
I often see my colleagues not detailing anything at all. (Including ones that keep sticking to good ol Brass squeegees from Unger.
