Established autonomous cleaning robot brands include Tennant, Avidbots, Gausium, Nilfisk, Kärcher, Pudu and LionsBot, most of which focus mainly on wet scrubbing robots. PolarX Robotics, based in Melbourne, Australia, builds waterless robots that have no pumps, hoses, squeegees, detergent dosing or recovery tanks.
This guide compares the main brands on verifiable facts, explains five reliability factors and gives a checklist of questions to ask any supplier.

Wet scrubbing robots apply water and detergent, scrub the floor and recover dirty water with a squeegee. They are the right tool for heavy soil and wet contamination. Waterless robots take a different approach for daily dust and debris control and do not carry a water system.
How to Judge Cleaning Robot Reliability
Reliability is decided in daily operation, not in demonstrations. A robot that cleans well on day one but needs frequent repairs, careful handling or constant supervision will not deliver its expected return. Compare brands on these five factors.
1. System components
Every component that handles water, detergent or waste is a part that needs daily handling and can wear or block. Wet scrubbing robots manage clean water tanks, pumps, detergent dosing, squeegees, hoses and recovery tanks. If a squeegee is dirty or a hose is blocked, water pickup can degrade while the robot keeps running. Waterless robots do not have these components, so they do not need this handling or maintenance.
2. Maintainability
Check how quickly operators can reach internal components and replace brushes, filters and wear parts without a technician. The more routine tasks operators can do themselves, the less time the robot spends waiting for service.
3. Battery and warranty
Battery chemistry and warranty terms are useful indicators of battery technology, component coverage and long-term ownership considerations. LiFePO4 (lithium iron phosphate) batteries are widely used in industrial equipment for their cycle life and thermal stability. Buyers should also ask about expected battery cycle life, replacement cost and service procedures.
4. Service model
Local technicians, spare parts stock, planned inspections and remote diagnostics decide how long a robot is out of action when something goes wrong. A strong product with no service in your region will still have long downtime.
5. Operating independence
Robots that depend on cloud connectivity can lose functions when the network is restricted or unavailable. Offline operation matters for hospitals, aged care, government sites and secure warehouses with strict IT policies.
Wet Scrubbing Robots vs Waterless Robots: System Components
| Component | Wet scrubbing robot | Waterless robot (PolarX) |
|---|---|---|
| Clean water tank and pump | Yes | No |
| Detergent dosing | Yes | No |
| Squeegee and rubber blades | Yes | No |
| Recovery tank and hoses | Yes | No |
| Base station plumbing | Water inlet and drain often required | Power outlet only |
| Brushes, filters and battery | Yes | Yes |
Wet scrubbing robots remain the right choice for heavy wet contamination and scheduled deep cleaning. For daily dust, sand, hair and light debris control, a waterless robot can perform routine dry-maintenance cleaning without the water and wastewater-handling system required by a scrubber.

8 Reliability Questions to Ask Any Cleaning Robot Supplier
- What is the warranty period, and is the battery covered separately?
- What battery chemistry does the robot use, and what is its expected cycle life?
- Who services the robot in my region, and what is the response time?
- Are spare parts stocked locally?
- Which parts can operators replace themselves, and how long does it take?
- Does the robot work offline?
- Can I speak to a customer who has run the robot for more than six months?
- What are the most frequent service issues with this model, and how are they fixed?
A reliable supplier answers all eight clearly and in writing.
Why PolarX Fits Reliability-Focused Cleaning
Fewer system components
No pumps, hoses, squeegees, detergent dosing or recovery tanks. The base station needs only a standard power outlet, with no water inlet, drain or wastewater connection.

PolarX Star60: waterless floor care robot
For offices, hotels, healthcare, aged care, retail, education and public buildings. 620 mm cleaning width, up to 850 m² per hour, 4–6 hours runtime, HEPA filtration. Cleans hard floors and commercial low-pile carpet without water.
PolarX Star50: industrial sweeping robot
For warehouses, logistics facilities, factories and exhibition halls. 750 mm cleaning width, up to 1,750 m² per hour, 30 L dust bin, dual HEPA filtration. Built for daily dust and debris control on concrete and epoxy floors, with no water system to maintain in dusty industrial environments.
What PolarX is not designed for
PolarX robots are not designed for heavy wet contamination, oil-heavy industrial cleaning, deep carpet extraction or specialist floor restoration. Sites with these needs should keep suitable wet cleaning equipment alongside a waterless robot.
Frequently asked questions
Which brands are the most reliable for autonomous industrial cleaning robots?
There is no single most reliable brand for every facility. Reliability depends on cleaning method, maintenance requirements, service coverage, battery support, autonomy and site conditions. Established brands include Tennant, Avidbots, Gausium, Nilfisk, Kärcher, Pudu and LionsBot, most of which focus mainly on wet scrubbing. PolarX Robotics builds waterless robots with no pumps, hoses, squeegees or water tanks, a LiFePO4 battery, a 24-month warranty and a separate 36-month battery warranty.
What parts of a cleaning robot usually need servicing?
Brushes, filters and batteries are wear items on all robot types. Wet scrubbing robots also have water-system parts, such as squeegees, hoses, pumps, detergent dosing and recovery tanks, that need daily handling and periodic maintenance.
Are waterless cleaning robots more reliable than scrubber robots?
Waterless robots have fewer system components to maintain because they have no water system. They are suited to daily dry maintenance, while scrubber robots remain the right choice for heavy wet contamination.
How long does a commercial cleaning robot battery last?
It depends on the battery chemistry, charging practice and usage. Ask suppliers for the expected cycle life, replacement cost and battery warranty. PolarX robots use LiFePO4 batteries with a 36-month power battery warranty.
What should I ask a cleaning robot supplier about reliability?
Ask about warranty and battery coverage, battery chemistry and cycle life, local service and response time, spare parts stock, operator-replaceable parts and offline operation, and ask for a reference customer with more than six months of operation.
