The video above walks through the full maintenance routine visually — this guide breaks it down into clear, repeatable steps you can follow at home. Whether you manage a family villa, a holiday rental apartment, or a hotel room in Greece, a robot vacuum only performs as well as its last clean. A neglected dustbin and clogged filter can cut suction by half within weeks, meaning your floors are dirtier than they look.
Why Regular Cleaning Matters More in Greek Homes
Greece's combination of sandy soil tracked in from beaches, fine dust blown in through open balcony doors, and long-haired pets creates a heavier-than-average load for robot vacuums. Most manufacturers rate their filters for 30 days between cleans, but in practice homes near the coast or in dusty areas may need attention every one to two weeks.
For holiday rental operators, a dirty robot vacuum is a guest-experience risk. A unit running with a full dustbin or a clogged brush roll simply redistributes debris instead of collecting it — and a guest who finds sandy floors will leave a review you cannot take back.
How Often Should You Clean Each Part
Different components wear at different rates. The dustbin needs emptying after every one or two runs. The filter should be tapped clean weekly and replaced every one to two months. The main roller brush and side brushes need hair and thread removed every two weeks, and the sensors and charging contacts need a wipe-down once a month. Following a schedule prevents small blockages from becoming motor failures.
Step-by-Step: How to Clean Your Robot Vacuum
- 1
Empty and wash the dustbin
Remove the dustbin after every cleaning cycle or every two runs at most. Tap it firmly over a bin to dislodge fine dust, then rinse it under cool running water. Let it air-dry completely — at least two hours — before reinserting. Never reinstall a damp dustbin, as moisture damages the filter and motor.
- 2
Clean and replace the filter
Remove the filter from the dustbin compartment and tap it gently against the inside of a waste bin to release accumulated fine dust. Do not wash foam or HEPA filters unless the manufacturer's manual explicitly permits it. Most filters should be replaced every four to eight weeks; keep a spare on hand so you are never caught short mid-season.

Clear the main roller brush and side brushes
Lay the vacuum upside down on a flat surface. Use the small cleaning tool that came with the unit — or a pair of scissors and a fine comb — to cut and pull out tangled hair, thread, and pet fur from the main brush roller. Remove the small side brush(es) by unscrewing the centre pin, clear any debris from the shaft, and reattach firmly. A gunked-up brush roll is the single most common cause of poor cleaning performance.

Wipe the sensors and charging contacts
Use a dry microfibre cloth or a cotton swab to gently wipe the cliff sensors on the underside of the unit, the front bumper sensor, and the infrared window on top. Then wipe the two charging contacts on the base of the robot and the matching pins on the dock with a dry cloth. Dirty contacts cause failed or slow charging; dirty sensors cause the robot to behave erratically near stairs or furniture.
- 5
Check the wheels and run a test cycle
Spin each drive wheel by hand and check that it rotates freely with no grinding. Remove any lodged thread from the wheel shafts. Place the cleaned unit back on its dock, let it charge fully, then run a single cleaning cycle and observe its path for the first few minutes. Smooth navigation and strong suction confirm everything is properly reassembled.

FAQ
- Can I wash the filter of my robot vacuum with water?
- Only if your manual says so. Most standard foam or HEPA filters are damaged by water and must be cleaned by tapping or gentle brushing only. Some brands — including certain Roborock and Ecovacs models — do include a washable filter; check your specific model's documentation before getting it wet.
- How do I know when to replace the brushes?
- Most robot vacuums display a brush-care reminder in the app after a set number of hours. As a rule of thumb, replace the main brush roller every six to twelve months and side brushes every three to six months, or sooner if the tips are visibly bent or worn flat — worn brushes sweep less effectively regardless of how clean they are.
- My robot vacuum smells bad after cleaning. What should I do?
- A musty or burning smell usually means the dustbin or filter is overdue for a clean, or that hair has been scorching on the brush motor. Empty and wash the dustbin, replace the filter, and clear all hair from the roller brush. If the smell persists after a full clean, the roller brush itself may need replacing, or the motor may have sustained heat damage and the unit should be serviced.
