Question about Einhell Varrito

From my point of view, no. The device is too small to smooth a surface as big as a table, it would take too long. Better a handheld sander.

With a second battery and enough sanding pads, yes. The sanding pads, especially the coarse ones, have to be changed often because the Velcro tape quickly wears out, even though the sandpaper would still be good.
