Using this vacuum tool set is easy. First, clip the handy caddy onto your standard 35mm vacuum pipe. Then, choose the right tool - the dusting brush for delicate surfaces like bookshelves or picture frames, the upholstery nozzle for sofas and chairs, and the crevice nozzle for tight spaces like between cushions or along baseboards. When using, make sure the connection between the tool and the pipe is secure to avoid air leakage. After each use, remove the tools from the caddy and clean them. You can use a damp cloth to wipe off the dirt. Store the tools in a dry place to prevent rust. If you notice any damage to the tools, stop using them immediately and contact us for a replacement. Enjoy cleaning with this versatile tool set!
