Had to pick up over 250 danish building brick studs from the floor by hand, and decided that will never happen again - next time I'm armed with the Tyson BricVac! I designed a vaccum cleaner accessory that filters out objects and sends them into a container. The filter has 1,5 mm openings, so in addition to small building block parts, it should be great for finding other small things that like to get lost, like small screws, earring backs etc. Just remember to place the filter between the BricVac and the vacuum cleaner before you go!
This fits any standard 33 mm vacuum cleaner hose. I used it on our Dyson v8 with a Dyson-to-33 mm adapter.
