Check the label and the fibre first — cotton, polyester, nylon, acrylic and polypropylene are usually fine; wool, silk, jute and shag are not. Vacuum both sides, spot-treat stains, then wash one rug with a couple of towels on a cold gentle cycle with mild detergent and an extra rinse. Air dry, or tumble on no heat if the label allows it.
The part worth pausing on is which rugs your machine can actually take, because every guide answers that with size and size is the wrong measure.
Weight decides this, not size
Maytag’s framing is the usual one: “small to medium-sized rugs, such as doormats or kitchen rugs, generally can fit into a standard washing machine,” while larger rugs “will likely be too cumbersome to handle the spin cycle or exceed the capacity of the machine” (how to wash rugs in a washing machine).
Note that they said two different things there — fitting, and exceeding capacity — and only the second one matters. A machine is rated in kilograms of dry laundry, not in square metres. A dense rubber-backed bath mat can weigh more than a full load of shirts while taking up a quarter of the space, and it then absorbs several times its own weight in water. That is how people overload a drum with something that looked small going in.
Weigh it. Stand on the bathroom scales holding the rug, then without it. If the dry rug is more than about a third of your machine’s rated load, it is a laundrette job — because the rug also needs room to tumble, and it will be far heavier wet. The general rule for how full a drum should be is in washer load size and how full to fill it.
The rubber backing question, answered honestly
Maytag is careful here and does not really commit: rugs with a rubber or latex backing “should be handled with extra care. You may be able to machine wash a rug with a rubber backing, but you should always consult the rug’s care label.” Whirlpool’s rug guide does not mention backings at all.
So there is no manufacturer statement to quote on what actually goes wrong, and this site would rather say that than invent one. What is observable is straightforward: latex and rubber backings stiffen, craze and eventually crumble with repeated heat and flexing, and once that starts, the crumbs come off in the drum. They are too small to see and too light to sink, so they end up in the filter.
The practical version: cold water only, never a hot wash, and never a heated dry. Heat is what ages the backing. A backed mat that has already gone stiff or started shedding on the bathroom floor should not go in the machine at all — it will finish disintegrating in there, and you will be picking it out of the filter.
Vacuum both sides, and do it for the machine’s sake
Everyone says vacuum first. Maytag gets closest to why, noting that skipping it “can also lead to clogging your machine’s drain.”
A rug is a grit trap. Months of shoe dirt, sand and pet hair are held in the pile, and none of it dissolves. In the drum it all washes out at once, and the drain pump filter is where it stops — which is a nuisance, and abrasive on the pump if it keeps happening. Vacuum both sides, take the rug outside and shake it, and expect to check the washing machine filter afterwards anyway.
How to wash a rug in the washing machine, step by step
- Read the label, check the fibre, weigh it. All three, in that order.
- Vacuum both sides, then shake it out outdoors.
- Patch-test the detergent. Whirlpool: “Patch test stain remover or laundry detergent in a hidden spot to make sure it’s color-fast” (how to wash and clean rugs). Rug dyes are often less stable than clothing dyes.
- One rug, plus two or three towels. Whirlpool again: “Position your rug in the washer with a few towels to help balance the load.” A single wet rug is a dense lump on one side of the drum, and the spin will refuse.
- Cold water, gentle cycle, mild detergent, extra rinse. Skip softener and bleach — Whirlpool warns these “can cause shrinkage or damage.” The extra rinse matters because a thick pile holds detergent.
- Air dry flat or over a rail. If the label permits a dryer, use no heat: Maytag’s phrasing is that “if your dryer has a No Heat setting, you may be able to tumble dry the rug using the no heat setting.”
Reshape it while damp, and give the pile a brush once it is dry.
The ones to keep out of the machine
Wool, silk, jute and shag are all on Maytag’s exclusion list, and the reasons differ. Wool felts — irreversibly, which is covered in why do clothes shrink in the wash. Jute is a plant fibre that weakens dramatically when saturated and can rot or smell if it does not dry fast enough. Shag tangles into mats that never separate again, and silk is silk.
Note also that Whirlpool and Maytag publish these lists as two brands of one company, so the agreement between them is less independent than it looks.
FAQ
Can you put a rug in the washing machine?
Small cotton, polyester, nylon, acrylic or polypropylene rugs, yes. Wool, silk, jute and shag, no. Weight and the care label decide the rest.
Can you wash a rug with rubber backing?
Sometimes, cold and on gentle, if the label allows. Never hot and never in a heated dryer, because heat is what makes the backing break up.
How often should you wash rugs?
Vacuum weekly. A full wash every six to twelve months for a high-traffic rug, less for one that sees little use.
What cycle should I use for a rug?
Cold water on gentle or delicate, with an extra rinse and the lowest spin — the same logic as any other bulky item.
Why won’t my washer spin the rug?
It cannot balance it. A soaked rug settles on one side as a single dense mass. Add towels, redistribute, and run the spin again.
Can you tumble dry a rug?
Only on a no-heat setting, and only if the care label allows. Heat shrinks the pile and destroys rubber backings.
The honest verdict
Weigh it, vacuum it, and keep the heat out of the whole process. Most of the damage done to rugs — and to washing machines — in this job comes from a hot wash or a hot dryer, not from the washing itself.
