Things You Should Never Vacuum (And What to Do Instead)

There's nothing quite like the feeling of a neat, tidy, freshly vacuumed home. Whether you're running a traditional upright, a robot vacuum, or a central vacuum system, cleaning up dirt and debris has never been easier—a central vacuum unit in Ottawa in particular is a great alternative to lugging around a heavy sweeper.

That said, not everything belongs in your vacuum. Sucking up the wrong material can damage your machine's motor, clog its filters, or ruin it completely—and that goes for canister vacuums, uprights, and robot vacuums alike.

Here's what to keep away from your vacuum in 2026:

Cosmetics and Makeup

Running the brush attachment over spilled powder, foundation, or eyeshadow tends to grind the stain deeper into carpet fibers rather than lifting it out. And if the product gets suctioned up, it can melt inside the machine, gumming up the internal mechanisms, hose, and canister or bag. Instead, scoop up as much as you can by hand first, then treat the remaining stain with a proper stain remover.

Ashes

Fireplace and fire pit ash is extremely fine — finer than most vacuum filters, including HEPA filters, are built to handle. It slips past the filtration system and coats internal components, which can clog the machine over time. Sweep up the bulk of the ash with a hand brush, then dab the area with a damp paper towel or cloth to pick up what's left. Keep in mind a damp towel may end up permanently stained.

Wet Food and Spills

Soup, cereal, sauce, pet food, or anything wet and soggy should be wiped up with paper towels or a microfiber cloth, not vacuumed. Wet debris can damage internal components on contact, and it's one of the fastest ways to void a warranty.

Water and Other Liquids

Standard vacuums are electric appliances, and liquids and electronics don't mix—vacuuming water can pose a real safety risk. Even a small amount of water can combine with existing dirt inside the machine to create a damp, musty mess that eventually mildews. If you need to pick up a spill mechanically, use a dedicated wet/dry shop vac. Otherwise, reach for towels.

Broken Glass

Glass shards, even tiny ones, can cut through hoses, filters, and internal seals, and larger pieces can get lodged in the tubing. Carefully sweep up bigger fragments and dispose of them safely first. For the smaller bits, press a damp paper towel onto them so they stick to the towel rather than dragging a cloth across the floor, which can scratch your flooring.

A Note for Robot Vacuum Owners

If you're relying on a robot vacuum to handle daily cleanup, the same rules apply — arguably more so. Robot vacuums have smaller intake ports and more delicate internal sensors, so cords, pet waste, small toys, and long hair are worth clearing off the floor before a scheduled run to avoid tangles, jams, or a stuck unit.
