To clean a cordless hoover, empty the bin after every session, wash the bin and filters roughly once a month, and clear hair from the brush roll whenever you see it wrapping. Always remove the battery or switch the machine off first, never get the battery or motor wet, and let washed parts dry for at least 24 hours before refitting them.

Before you start: safety

Most cordless hoovers have the motor and battery in the handle. Water and lithium-ion batteries do not mix, so the golden rule is simple: the only parts that go near a tap are the parts your manual says are washable.

You will need: a bin bag, scissors or a seam ripper, a dry microfibre cloth, a soft brush (an old toothbrush works), and a dry, warm room for drying. Skip washing-up liquid, detergents and hot water unless your manual says otherwise; most brands specify cold water only.

How often to clean each part

If you have pets or hoover daily, double the frequency for filters. For a deeper explanation of filter types, see HEPA filters explained.

Step 1: Empty and clean the bin

1. Remove the battery or make sure the machine is off and off the charger.
2. Hold the bin inside a bin bag (this keeps fine dust down, which matters if anyone has allergies) and press the bin release. On Dyson sticks this is the red lever; on many Shark, Vax and Samsung models it is a button or latch on the bin.
3. Shake out any debris stuck to the mesh shroud. If hair is wrapped round it, pull it off with your fingers or a dry brush rather than poking with anything sharp.
4. Once a month, take the bin off fully (most models allow this; check your manual) and wipe inside with a dry or barely damp cloth. If your manual says the bin is washable, rinse it in cold water.
5. Leave the bin to air dry for 24 hours before reattaching. A damp bin turns fine dust into paste that clogs the cyclone.

Self-emptying bases (Shark Clean & Empty, Samsung Clean Station and similar) still need attention: the stick's own bin seal and the base's bag or bin should be checked monthly. Our self-emptying hoovers guide covers how these bases differ.

Step 2: Clean the cyclone and shroud

The cyclone assembly is the cone section between bin and motor. On most models it is not washable because it is fixed to the motor body.

1. Brush the outer shroud and cone openings with a dry soft brush.
2. Wipe the outside with a dry microfibre cloth.
3. Look into the cyclone openings with a torch. Grey felted dust here is a common cause of lost suction.
4. Do not run water through a non-removable cyclone; it can reach the motor.

Step 3: Wash and dry the filters

Filters are the most neglected part and the most common reason a cordless hoover pulses, loses suction or smells. Most sticks have one or two filters: a pre-motor filter (between bin and motor) and a post-motor or HEPA filter (on the exhaust). Some, like the Dyson V11 and V15, combine them into a single cylindrical filter at the back.

1. Remove the filter (twist, pull or unclip as shown in your manual).
2. Tap it firmly against the inside of a bin bag to release loose dust.
3. If the manual says it is washable, rinse under a cold tap only. Fill foam filters, squeeze, and repeat until the water runs clear. Pleated filters should be rinsed gently and tapped, not scrubbed.
4. Shake out the excess water and leave the filter to dry naturally for at least 24 hours (48 is safer for thick foam or pleated filters).
5. Do not use a radiator, tumble dryer, oven, hairdryer or microwave. Heat can warp the filter and the seal.
6. Refit only when completely dry. A damp filter can let water reach the motor and can grow mould, which you will then smell every time you hoover.

Washed filters still wear out. If a filter is torn, misshapen, or stays grey after rinsing, replace it. Genuine filters are usually inexpensive; buy the part matched to your exact model.

Step 4: Clear the brush roll and floor head

1. Detach the floor head from the wand.
2. Remove the brush roll if your model allows (usually a coin-turn cap or a slide catch at one end).
3. Cut along the groove in the brush roll with scissors or a seam ripper, keeping the blade away from the bristles, and pull hair away.
4. Pull threads out of the end caps; this is where hair wraps tightest and where it causes bearing wear.
5. Check the neck of the floor head for blockages such as hair clumps or a sock.
6. Soft fluffy rollers (Dyson Fluffy, Shark soft rollers) can usually be rinsed in cold water if the manual says so; dry them standing on end for 24 hours. Never wet a roller that has an internal motor.

Step 5: Wand, tools and the outside

1. Look through the wand towards a light. Anything blocking it should be pushed out with a broom handle, not something sharp that could pierce a seal.
2. Clear the crevice tool and mini motorised tool of hair the same way as the main brush roll.
3. Wipe the body and battery contacts with a dry cloth. Dusty contacts can cause charging problems; see cordless hoover not charging.
4. Reassemble, refit the battery and run on low for a few seconds to check everything clicks in and suction is even.

Common problems after cleaning

When to stop and call the manufacturer

Cleaning fixes most suction, smell and pulsing problems. Stop using the hoover and contact the manufacturer if you notice any of the following: a burning smell that continues after cleaning, a battery that is swollen, hot or cracked, water inside the motor or battery, or flashing fault lights that do not clear. If the machine is within warranty, check our warranty guide before paying for a repair.
