Reading time: approx. 10 minutes

The best cleaning robot for companies does not depend on the floor size alone. The type of flooring, level of soiling, aisle width, foot traffic, and desired cleaning method determine which system makes economic and technical sense. For compact and complex layouts, models like the PUDU ET1 or Gausium Phantas are particularly interesting. For large industrial and logistics areas, however, powerful sweeping and scrubbing systems such as the PUDU BG1 Pro, PUDU MT1, Gausium Beetle Pro, or Gausium Scrubber 75 are viable options.

Terra Robotics compares ten current cleaning robots for commerce and industry from PUDU Robotics, Gausium, and ikitbot. The comparison shows which model suits which area of application and which criteria companies should consider before making a selection.

Which cleaning robot is the best in 2026?

There is no single "best" cleaning robot. The best model is the robot whose cleaning method, dimensions, navigation, and level of automation match the specific site.

A supermarket with narrow aisles presents different requirements than a production hall with dust, packaging waste, and forklift traffic. In a hotel, on the other hand, noise levels and compact dimensions play a greater role than maximum area coverage.

That is why Terra Robotics evaluates cleaning robots not exclusively according to maximum technical values, but according to their fit for the real-world application area.

Gausium Beetle Pro Sweeping and vacuuming Warehouse and production Coarse dirt and large bin
PUDU BG1 Pro Sweeping and scrubbing Large hard floor areas Large-scale wet cleaning
Gausium Scrubber 75 Intensive scrubbing Industry, logistics, parking garages Large and heavily soiled areas

This classification is not an independent laboratory test or a general ranking from first to tenth place. The specific application profile is always the deciding factor.

1. PUDU ET1: for narrow and dynamic commercial spaces

The PUDU ET1 is particularly suitable for companies with narrow aisles, dense furniture, and frequently changing floor layouts.

The compact cleaning robot only requires an aisle width of about 50 centimeters and can reach areas with heights starting from around 60 centimeters. This makes it interesting for supermarkets, retail stores, office buildings, hotels, clinics, and public facilities, for example.

Another special feature is adaptive cleaning. The ET1 can detect floor conditions and dirt, adjusting its cleaning parameters accordingly.

Suitable for:

  • Supermarkets and retail

  • Office buildings

  • Hotels

  • Clinics and care facilities

  • Schools and public buildings

  • Gastronomy and food courts

Its strength lies less in maximum area coverage than in deploying autonomous floor cleaning where larger machines reach their limits due to narrow spaces.

2. Gausium Phantas: compact all-rounder for mixed floor surfaces

The Gausium Phantas is particularly interesting for small to medium-sized indoor areas with different floor coverings and many edges or narrow spots.

Phantas combines sweeping, vacuuming, scrubbing, and dusting in a compact system. With a required aisle width of around 600 millimeters, it is also suitable for buildings where larger cleaning machines can only be used to a limited extent.

A special feature is its very close-to-edge cleaning capability. This allows areas along walls to be better integrated into the automated cleaning process.

Phantas is suitable for, among others:

  • Offices

  • Hotels

  • Retail

  • Educational institutions

  • Hospitals

  • Smaller retail spaces

Especially with mixed hard and carpeted floors, a multifunctional cleaning robot is advantageous because a separate system is not required for every floor area.

3. ikitbot ONE S55: quiet cleaning for public areas

The ikitbot ONE S55 is particularly suitable for buildings where cleaning should take place alongside normal operations.

With an operating noise level of about 55 dB in cleaning mode, the system is interesting for offices, hotels, clinics, schools, and sales areas.

The ONE S55 combines several cleaning methods and works with multi-sensor navigation using LiDAR, cameras, and further environmental sensors. Obstacles and people can be detected and considered in route planning.

Typical areas of application include:

  • Office buildings

  • Hotels

  • Clinics and care facilities

  • Schools

  • Shopping centers

  • Airports and transport hubs

For companies with long opening or operating hours, a low noise level can be more decisive than the highest possible theoretical area coverage.

4. PUDU CC1: versatile 4-in-1 cleaning robot

The PUDU CC1 is a versatile cleaning robot for companies wanting to automate different floor cleaning tasks with a single system.

CC1 combines sweeping, vacuuming, mopping, and scrubbing. This makes the model suitable for commercial indoor areas with changing cleaning requirements.

Navigation is based on visual and laser-based environmental sensing. The robot can adjust its route to changes in the environment and return autonomously to a corresponding station.

CC1 is particularly interesting for:

  • Retail

  • Shopping centers

  • Office buildings

  • Hotels

  • Schools and universities

  • Clinics

  • Public buildings

Companies looking to automate larger parts of their regular floor cleaning for the first time gain a widely applicable platform.

5. PUDU CC1 Pro: AI-supported cleaning and automatic follow-up control

The PUDU CC1 Pro is particularly suitable for companies that require more intelligent detection and control of soiling in addition to autonomous cleaning.

The system combines sweeping, vacuuming, mopping, and scrubbing with AI-assisted stain detection.

During operation, dirt can be detected and specifically treated. A rear-facing camera additionally checks the cleaning result. If residual soiling is detected, follow-up cleaning can be triggered.

Digital heatmaps provide additional transparency regarding cleaned areas.

This makes the CC1 Pro particularly interesting for:

  • Facility management

  • Shopping centers

  • Hotels

  • Healthcare

  • Public buildings

  • High-traffic commercial areas

This shifts professional cleaning robotics from rigid routes increasingly toward needs-based cleaning.

6. Gausium Omnie: for large and dynamic indoor areas

The Gausium Omnie is particularly suitable for large areas with high foot traffic and frequently changing obstacles.

Omnie combines extensive environmental awareness with AI-supported cleaning. A 360-degree camera and further sensors support the robot in orienting itself in dynamic environments.

Depending on the configuration, the system achieves a theoretical cleaning performance of up to 3,600 square meters per hour.

Omnie is particularly interesting for:

  • Shopping centers

  • Airports

  • Train stations

  • Logistics centers

  • Large retail areas

  • Public buildings

AI-supported spot cleaning also enables targeted treatment of localized soiling, rather than permanently cleaning every area with the same intensity.

7. PUDU MT1: for dry dirt in industry and logistics

The PUDU MT1 is particularly suitable for large areas where dust, packaging waste, and other dry debris regularly occur.

The autonomous sweeping robot uses cameras and AI to identify different types of waste. Combined with LiDAR and visual navigation, it can also be used in dynamic industrial and logistics environments.

The MT1 has a 35-liter waste bin and achieves a theoretical area performance of up to 1,800 square meters per hour in the standard version.

Typical fields of application are:

  • Warehouses

  • Logistics centers

  • Production areas

  • Shipping zones

  • Large traffic areas

  • Industrial commercial areas

For companies with predominantly dry coarse and fine dirt, a specialized sweeping robot is often more sensible than a classic wet-cleaning robot.

8. Gausium Beetle Pro: autonomous sweeping for warehouse and production

The Gausium Beetle Pro is particularly suitable for warehouse and production areas with dust, sand, abrasion, packaging residues, or other dry dirt.

The industrial sweeping and vacuuming robot combines a cleaning width of 750 millimeters with a 45-liter waste bin. The theoretical cleaning performance is up to 2,000 square meters per hour.

3D-LiDAR supports navigation, mapping, and obstacle detection in complex hall environments.

This makes the Beetle Pro particularly interesting for:

  • Warehouses

  • Distribution centers

  • Production facilities

  • Workshops

  • Packing and shipping areas

  • Industrial traffic routes

Before selecting, companies should therefore first distinguish whether they primarily need to pick up dry dirt or intensively wet scrub the floor.

9. PUDU BG1 Pro: sweeping and scrubbing on large hard floors

The PUDU BG1 Pro is suitable for large hard floor areas where sweeping and intensive wet cleaning are to be combined.

The system combines sweeping and scrubbing in one workflow and features extendable edge cleaning.

With 75 liters of fresh water and 60 liters of dirty water, the BG1 Pro is designed for longer operations on large surfaces. The theoretical surface-covering cleaning performance is up to 2,000 square meters per hour.

Typical locations are:

  • Industrial halls

  • Logistics centers

  • Production areas

  • Large retail areas

  • Transport centers

  • Other extensive hard floor areas

LiDAR and 3D-VSLAM support autonomous navigation and dynamic obstacle avoidance.

10. Gausium Scrubber 75: intensive cleaning of very large areas

The Gausium Scrubber 75 is particularly suitable for large and heavily used hard floors requiring intensive wet cleaning.

With a scrubbing width of 750 millimeters and a theoretical cleaning performance of up to 3,000 square meters per hour, this model is designed for large areas.

The fresh water tank holds 75 liters. A high brush pressure supports the treatment of heavier soiling.

The Scrubber 75 is particularly suitable for:

  • Industrial halls

  • Warehouses and logistics

    • Parking garages

  • Shopping centers

  • Transport hubs

  • Large public facilities

The larger and more uniform the area, the more effectively a large-area scrubber can demonstrate its productivity.

Which cleaning robot fits which area of application?

The right cleaning robot is best chosen based on the actual area of application.

Retail and supermarket

For supermarkets and retail, compact dimensions, safe navigation, and a good reaction to foot traffic are decisive.

Particularly interesting are:

  • PUDU ET1

  • Gausium Phantas

  • ikitbot ONE S55

  • PUDU CC1 Pro

  • Gausium Omnie

Office and hotel

In office buildings and hotels, noise levels, compact navigation, and different floor types play a major role.

Suitable models can be:

  • ikitbot ONE S55

  • Gausium Phantas

  • PUDU ET1

  • PUDU CC1

  • PUDU CC1 Pro

Industry and logistics

In production and warehouse cleaning, the type of soiling and the size of the area determine the selection.

For dry dirt and packaging waste, the following are particularly suitable:

  • PUDU MT1

  • Gausium Beetle Pro

For intensive wet cleaning of large hard floors, the following options, among others, should be considered:

  • PUDU BG1 Pro

  • Gausium Scrubber 75

  • Gausium Omnie

Hospital and care facilities

In healthcare, reproducible processes, minimal operational disruption, and verifiable cleaning are particularly important.

Depending on the area, models such as the PUDU CC1 Pro, ikitbot ONE S55, PUDU ET1, or Gausium Phantas may be suitable.

What criteria are crucial when purchasing a cleaning robot?

Floor space alone is not enough to select a cleaning robot. At least six factors should be evaluated before making an investment.

1. Floor type

Hard floors, carpet, concrete, epoxy resin, and coated floors require different brushes and cleaning methods.

2. Type of soiling

Dust and packaging waste present different requirements than liquids, foot traffic marks, or stubborn dirt.

3. Passage width

Narrow hallways and shelving aisles can rule out large cleaning robots. Models like the PUDU ET1 or Gausium Phantas are specifically interesting for more compact areas.

4. Cleaning area

Large, open halls benefit more from wide cleaning machines and large tanks. Small, complex buildings, however, require more maneuverability.

5. Pedestrian and vehicle traffic

In supermarkets, hospitals, or logistics centers, the environment is constantly changing. Sensor technology and dynamic obstacle detection thus become particularly important.

6. Degree of automation

Automatic charging, water refilling, wastewater disposal, fleet management, and digital cleaning reports can significantly reduce the manual support effort.

When is a cleaning robot economically viable?

A cleaning robot is worth it when sufficient repetitive floor cleaning can be automated, allowing working time to be used more effectively.

Decisive factors include, among others:

  • net area to be cleaned daily

  • number of cleaning days

  • required working hours

  • personnel costs

  • opertational time of the robot

  • acquisition or financing costs

  • maintenance and service costs

  • necessary docking or water stations

Therefore, a high theoretical square-meter value alone provides little information about actual economic viability.

With the ROI calculator for cleaning robots, companies can perform an initial profitability assessment based on their own floor space, operating time, and cost structure.

Cleaning robots do not replace all manual cleaning

Autonomous cleaning robots primarily handle repeatable floor tasks and complement existing cleaning teams.

Sanitary areas, furniture, surfaces, stairs, hard-to-reach corners, and situation-specific special cleaning tasks still require human labor.

The economic advantage often arises not from completely replacing manual cleaning, but from a new distribution of tasks.

The robot takes over plannable areas.

Employees focus on more complex work.

Especially in large properties, long operating hours, or in the event of personnel shortages, this combination can make cleaning processes more predictable.

Conclusion: The largest cleaning robot is not automatically the best

The best cleaning robot for 2026 is the model that fits a company's real floor space and actual cleaning process.

For narrow and complex indoor areas, compact systems like the PUDU ET1 or Gausium Phantas are interesting. The ikitbot ONE S55 scores in noise-sensitive buildings. The PUDU CC1 and CC1 Pro cover versatile commercial applications.

For large, dynamic areas, the Gausium Omnie shows its strengths.

In industry and logistics, the decision depends heavily on the type of soiling: the PUDU MT1 and Gausium Beetle Pro focus on dry sweeping, while the PUDU BG1 Pro and Gausium Scrubber 75 are designed for intensive cleaning of large hard floor surfaces.

The selection should therefore always begin with the floor space, floor type, type of soiling, bottlenecks, and the desired degree of automation – not with a specific robot model.
