Central vacuum
or robot vacuum?
The robot cleans automatically — that's its advantage. But can it really replace a central vacuum? Power, stairs, carpets, air exhaust: here are the concrete differences.
Robot vacuum
vs. central vacuum.
Automatic autonomy or maximum power? These two solutions don't really compete — they address different needs.
| Criterion | Robot vacuum | AspiWall central vacuum |
|---|---|---|
| Suction power | 100–400 AW depending on model | Up to 1,354 AW continuous |
| Operation | Automatic (programmable) | Manual — targeted and controlled cleaning |
| Stairs | No — structural limitation | Yes — light hose, inlet at each level |
| Corners & edges | Partial — depends on model | Yes — dedicated brushes |
| Furniture & sofas | No | Yes — dedicated nozzles and brushes |
| Thick carpets & rugs | Limited — insufficient power | Yes — motorised high-power brushes |
| Exhaust air | In the room (filtered) | At the unit, outside living spaces |
| Noise in the room | 55–70 dB during cycle | Very low (relocated motor) |
| Bin capacity | 0.2–0.6 L (frequent emptying unless self-emptying) | Large central bin — empty 1–2×/year |
| Lifespan | 4–8 years | Central unit 15–20 yrs · durable network |
| Investment | €300–1,500 (unit only) | Complete installation — central unit 15–20 yrs, durable network |
Automation
or cleaning power?
Robot vacuum
- Works alone — ideal for daily maintenance
- Programmable remotely via an app
- Cannot do stairs or furniture
- Limited power on carpets and rugs
- Can get stuck, lost or fall
- Regular maintenance (brushes, filters, bin or station)
- Filtered air exhausted back into the room
- Lifespan limited to 4–8 years
AspiWall central vacuum
- Constant power up to 1,354 AW — no time limit
- Cleans stairs, furniture, sofa, car
- Relocated motor — silence in living spaces
- Exhaust air directed to unit, outside living spaces
- Light hose, inlets at every level
- Large central bin — empty 1–2×/year only
- PVC network with no wearing parts
- Durable installation: central unit 15–20 yrs, PVC network with no wear
The limits of
each solution.
What the robot will never do
Stairs, furniture, sofa cushions, thick carpets, hard-to-reach corners and the inside of the car are all out of reach for any current robot. For these areas, manual cleaning with a powerful vacuum is essential.
Central vacuum requires installation
Unlike a robot you take out of its box, central vacuum is integrated into the building — PVC pipe network, wall inlets, unit in a utility room. It's an investment to plan, ideally during construction or renovation.
Robot maintenance underestimated
The robot's brushes quickly become clogged (hair, threads), filters need cleaning or replacing, and the bin must be emptied after each cycle (except self-emptying models). AspiWall central vacuum only requires emptying the bin 1–2 times a year.
When to choose
which solution?
Robot suits you if…
- You want automatic daily floor maintenance
- Your home is mainly on one level (no stairs)
- You have pets and want daily hair collection
- You are often away and want a clean floor on your return
- You use it as a complement to another vacuum
AspiWall central vacuum suits you if…
- You want thorough, deep cleaning
- Your home has stairs, carpets or difficult areas
- You need to clean furniture, sofa and the car
- Noise and air exhaust in the rooms bother you
- You own the property and think long-term
- You want to avoid repeated purchases and regular appliance maintenance
No, the two tools are complementary. The robot maintains floors daily automatically on accessible flat surfaces. AspiWall central vacuum handles complete cleaning: stairs, furniture, sofas, corners, carpets, car — with up to 1,354 AW that no robot reaches.
Robot vacuums generally reach 100–400 AW depending on the model. The AspiWall S500 central vacuum delivers up to 1,354 AW continuously. For pet hair embedded in carpets or dirt in corners, the power difference is immediately noticeable.
No. Current robots cannot go up or down stairs — it's one of their structural limitations. AspiWall central vacuum, with its lightweight hose, allows you to clean stairs step by step, railings and walls, without carrying heavy equipment.
Yes. Like any conventional vacuum, the robot sucks and filters air before exhausting it back into the room. With AspiWall central vacuum, the exhaust air is directed to the unit installed outside living spaces — it never comes back into the cleaned area.
Yes, it's actually a common combination. The robot handles automatic daily floor maintenance on smooth surfaces. AspiWall central vacuum handles deep cleaning, stairs, furniture, carpets and all areas inaccessible to the robot.
Partially. Self-emptying robots reduce manual interventions, but their power is insufficient to dislodge hair deeply embedded in carpets or between floorboards. AspiWall central vacuum, with its motorised brushes and high power, is significantly more effective on these surfaces.
