“Is this complicated to use?”
Not at all. If you can hold a bottle, you can use this.
“Do I need a water connection?”
No. That’s the whole point — bucket, pool, whatever you have.
“Is it strong enough?”
Strong where it matters: removing dirt, not damaging surfaces.
“Is it heavy?”
No. You can use it with one hand — even for a full car.
“Who is this for?”
Anyone who’s tired of wasting time cleaning.
