The red cleaning trolley by Theo Klein is the toy version of the cart grown-ups drag through the house. A handle at the top, two big wheels at the bottom, and between them a rack where the gear fits neatly. Everything is finished in Vileda style, right down to the cardboard box of detergent.
The set holds a bucket with a wringer attachment, a mop with a handle, a broom, a hand brush, a dustpan and that box of detergent. Your child fills the bucket, wrings out the mop, sweeps the crumbs onto the dustpan and then rolls everything back into place - exactly the order they see it happen at home. It stays role play: this is a toy, not real cleaning equipment.
The trolley is roughly 60 cm tall and 29 cm wide, so it is scaled to preschool hands. You put it together yourself in a few steps. Theo Klein gives this article from 3 years.
A nice present for a child who always wants to help, and a good addition to a play kitchen or a doll's corner.
