Started in 2007 at a family vacuum repair shop.
Think Crucial began with replacement parts listed online from a family vacuum repair shop. The repair counter was the education: which parts wore out first, and how often a customer paid a shop for a swap that takes five minutes.
We make what we sell: aftermarket filters, bags and parts built to fit the machines you already own, and our own descalers and cleaners. Most people can fit the part themselves. They just need the right one, and a way to check it before they buy.
What the counter taught usSince 2007
- Filters that clog first
- Belts that snap
- Hoses that crack at the cuff
Check the models and part numbers on each product page before you order.
Brand and model names are trademarks of their owners and are used only to show what a part fits. Think Crucial is an independent brand and is not affiliated with or endorsed by those manufacturers.

Air pre-filter
Have gotten these before but don’t know if they were washable, seems of good quality but will see over the next few months.

Time will tell but looks and works great.

AWESOME Shark Hose Handle
This Shark hose is a fraction of the cost of an OEM product! Stocked up on them as the Shark company itself does not manufacture reliable hoses. Thank you, thank you! :)
