I’m finding it difficult to decide which of these to buy

I need something to clean hardwood & laminate flooring

I’ve been into my local JLP shop who unfortunately don’t have a Wash G1 to demonstrate & then discuss

Reviews of the Wash G1 seem varied and it is Generation 1, so I am nervous about buying it

Could someone advise me please

Wash G1 experience ? use

Submarine experience / use

thanx

Anthony
