Their only limitation is the VC 4 and T20+ can’t vacuum liquids. For this, a KARCHER or AIRROBO ‘wet and dry’ vacuum is needed.

Most Airrobo and Karcher battery powered vacuums include accessories. Check T20+ or VC 4 manual for specifications and attachments.

The VC 4 and AIRROBO T20+ include effective filters to capture dust, dander, pollen, hairs, and fibres.
