Top Tips for Maintaining Your Refurbished Robot Vacuum

A refurbished robot vacuum from Big Warehouse Refurbs arrives in excellent working condition — but like any appliance, a little regular maintenance goes a long way. Here are five simple tips to keep your robot vacuum performing at its best for years to come.

1. Empty the Dustbin Regularly

Even a large dustbin will fill up over time, and a full bin reduces suction power. Get into the habit of checking it after every few sessions. If your model has an auto-empty dock — like the Dreame Z10 Pro or the Roborock S7 MaxV with an optional dock — the dock handles this automatically, but it's still worth checking the main bin periodically.

2. Clean or Replace Filters

Filters trap fine dust and allergens. Over time they clog, reducing airflow and suction. Most robot vacuums recommend cleaning filters every two to four weeks. If your filter is washable, rinse it under cold water and let it dry completely before reinserting. Non-washable filters should be replaced every one to three months depending on usage.

3. Untangle the Brushes

Side brushes and main roller brushes collect hair, thread, and debris over time. Tangled brushes are one of the most common causes of reduced cleaning performance. Check them every few sessions and use the included cleaning tool or scissors to remove any buildup. Some models, like the Dreame W10, have self-cleaning brush systems that reduce this significantly.

4. Wipe the Sensors

Robot vacuums rely on cliff sensors, wall sensors, and camera sensors to navigate accurately. A dusty sensor can cause erratic movement, missed areas, or the vacuum getting stuck. Every few weeks, use a dry soft cloth to gently wipe the sensors on the underside and front of the unit.

5. Keep the Software Updated

Most modern robot vacuums — including Dreame, Roborock, and Tapo models — connect to a smartphone app. Software updates improve navigation, add cleaning modes, and fix bugs. Check your app regularly to make sure your vacuum is running the latest firmware.
