Quick Answers & FAQ

This is a thermal cutoff activation — a safety switch that shuts the motor down when it overheats from restricted airflow. Let it cool 30 minutes, clear all airflow restrictions (empty bin, clean all filters, check for hose blockage), then press the small reset button on the body or base before restarting. If it keeps happening with no obvious restriction, the motor's internal cooling fan may be damaged. Full guide →

A new noise is a diagnostic signal. Rattling = something hard (coin, stone, plastic) entered the airpath and is bouncing around — turn off immediately and check the hose and floor head. Squealing = worn belt or dry brush roll bearing. Grinding = debris in the motor path or a damaged fan blade — stop use and inspect. Noise diagnosis guide →

Check in this order: (1) Is the outlet working? Plug something else in to test. (2) Is the cord damaged or the connection loose? (3) Has the thermal cutoff tripped? Look for a small reset button on the body or base and press it. (4) Is there a blown internal fuse? This requires opening the vacuum body to test. Full guide →

Most commonly a full dustbin — robot bins are tiny and must be emptied after every cycle. Also check: worn or hair-wrapped side brushes that aren't sweeping debris into the path; dirty cliff sensors causing the robot to avoid clean areas it misidentifies as edges; and whether furniture has moved requiring a map update.

Pre-motor foam filters: clean monthly, replace every 6 months. Washable HEPA filters: rinse every 3 months, replace every 12–24 months as filtration media degrades. Non-washable HEPA filters: replace every 6–12 months. Never put a damp filter back in the vacuum — allow 24 hours for pre-motor filters and 48 hours for HEPA filters to dry completely. Filter guide →

Inspect every 6 months, replace every 6–12 months under normal household use. Replace immediately if you notice: a burning rubber smell, the brush roll stopping while the motor runs, visible cracks or glazing on the belt surface, or the belt feeling loose when you press it with a finger. Belts cost $5–15 — always use the manufacturer's correct part number. Belt replacement guide →

No. Machine wash heat and detergent damage filter media regardless of whether the filter is labelled washable. The "washable" label means cold water rinse by hand only — no hot water, no soap, no machine. Even gentle machine cycles reach temperatures that warp filter frames and degrade filtration fibres.

Baking soda: in small amounts yes, but large quantities pass through filters and cause abrasive motor wear — vacuum in a single slow pass rather than going back and forth. Fireplace ash: never vacuum ash with a standard vacuum. Ash particles are extremely fine and will pass through most filters into the motor, causing rapid wear and potentially carrying live embers that can ignite dust inside the vacuum. Use a purpose-built ash vacuum with a metal canister if you must vacuum ash.

For most common repairs, yes — repair is absolutely worth it. Belt replacement ($5–15), filter replacement ($10–35), hose replacement ($20–55), and brush roll replacement ($20–45) are all cheap and easy. The decision flips with motor replacement ($60–150+): if repair cost exceeds 50% of the vacuum's replacement value, buying new usually makes more financial sense. Diagnose the exact fault before deciding — most performance problems are cheap to fix. Full decision guide →

The model number is almost always on a sticker on the base of the vacuum — flip it upside down and look for a label with "Model:" or "Model No:" followed by a code. On upright vacuums it may also be on the back of the body. On robot vacuums, check the underside near the dustbin. On cordless stick vacuums, check where the wand connects to the body. Write it down before ordering any parts — it's the only reliable way to ensure compatibility.

Short run time on a cordless vacuum is almost always battery degradation — lithium-ion batteries lose capacity over charge cycles and typically retain good performance for 2–3 years before noticeable decline. Other causes: using the vacuum on maximum power mode when a lower setting would suffice; a clogged filter forcing the motor to work harder; or a partially blocked bin. If the battery is more than 2 years old and run time has dropped significantly, battery replacement ($35–80) is usually the right fix. Battery replacement guide →

Hard floors: 1,500–2,000 Pa is sufficient. Low-to-medium pile carpet: 2,000–3,000 Pa minimum. Deep-pile carpet or heavy pet hair: 3,000+ Pa. Note that on carpet, brush roll quality matters as much as suction — a good brush roll on a 2,000 Pa vacuum will outperform a poor brush roll on a 4,000 Pa vacuum. Wattage ratings measure power consumption, not suction — use Pa or AW as your comparison metric. Suction power explained →

Bagged vacuums seal dust in a bag that you throw away — cleaner disposal, better for allergy sufferers, maintains more consistent suction as the bag fills. Bagless vacuums are convenient and have no ongoing bag cost, but emptying the bin releases a dust cloud that can aggravate allergies. Suction-wise, a well-designed bagless vacuum is comparable to a bagged one. For allergy households, bagged is generally recommended. Full comparison →

Yes — as a supplement to a full-size vacuum, not a replacement. Robot vacuums handle daily maintenance automatically, which means your full-size vacuum only needs to do periodic deep cleaning. The combination is genuinely time-saving. As a sole vacuum, a robot underperforms on thick carpet, cannot do stairs or above-floor surfaces, and requires more frequent bin emptying than its "automatic" branding implies. Budget at least $200–300 for a robot vacuum that performs reliably — cheaper models have navigation and reliability problems that make them frustrating to own.
