Not good to empty a cellar -

Unhappy with the result that point because it means that it takes 20 cm of water in the cellar before seeing aspire.
Cable float system seems not good either - too long to empty cable 20cm of water (probably expected to wait 30 to 40 cm water).
Essential non-return valve to help the pump to boot - if not it turns easily dry.

"Tools and accessories"? Yes, we need tools and accessories for there is nothing that the manual and multi-Diameter adapter.

Perhaps a good product to clear something big and deep, but not a cellar.

Correct price so I'll make do. 48H delivery.
