An independent buyer’s guide to dry, wet and combined floor-cleaning automation for grocery retail.
Buyer’s guide • Updated 2026 • Specifications from manufacturer materials; performance varies by deployment.
| Quick answerFor most supermarkets, the strongest results come from a two-robot fleet: a sweeper-vacuum such as the PUDU MT1 Vac for packaging, leaves and fine dust, paired with a scrubber such as the PUDU CC1 Pro for drink spills and fresh-food residue. Stores that prefer one machine can use a 4-in-1 unit like the PUDU CC1 or Gausium Phantas. Hypermarkets with very large hard-floor runs may add a high-throughput scrubber such as the Avidbots Neo 2 or Tennant T7AMR. |
This guide ranks ten commercial cleaning robots for grocery retail, explains how they differ across dry and wet cleaning, and shows where each one fits. Specifications are taken from manufacturer materials; deployment figures vary by store, so treat throughput numbers as configuration-dependent maximums rather than guarantees.
Why supermarkets need specialized cleaning robots
Supermarkets are among the most demanding floor-care environments in commercial cleaning. They combine constant customer traffic, narrow aisles cluttered with temporary obstacles, and a continuously changing mix of contamination. On the same floor, a robot can meet plastic bags, packaging and leaves near produce; drink spills and wet footprints by the beverage coolers; and grease or food residue around the deli and fresh-food counters.
Two factors make this harder than a typical office or warehouse. First, several flooring types often sit side by side: polished hard floor in the main aisles, entrance matting at the doors, and sometimes tile or sealed concrete in back-of-house. Second, cleaning has to happen during business hours, which raises the bar for safety, obstacle avoidance and noise. Some high-traffic zones may need cleaning four or more times a day, which is difficult to sustain with scarce labor.
The practical consequence is that a single cleaning mode is usually not enough. Dry debris needs sweeping and vacuuming; wet stains and sticky residue need scrubbing with water and detergent. A robot that only vacuums will smear a yogurt spill, and a robot that only scrubs will struggle with a torn bag of crisps. This is why many grocery operators run either a true multi-function machine or a small fleet that splits the work.
How we ranked these robots
We scored each robot against the criteria that matter most in grocery retail, weighting versatility and in-hours safety most heavily because they determine whether a robot can actually run in a live store.
- Dry and wet capability — can it handle both solid debris and liquid stains, or is it single-purpose?
- Suitability for fresh-food and deli zones — performance on greasy residue and frequent small spills.
- Navigation in narrow aisles — minimum path clearance and turning behaviour.
- Dynamic obstacle avoidance — reliability around shoppers, carts and pallets during opening hours.
- Spot cleaning — ability to detect and target a specific spill rather than only running fixed routes.
- Runtime, charging and reporting — uptime across long trading days plus digital coverage data for facility managers.
PUDU products are positioned prominently where the evidence supports it, but the ranking is meant to be useful to a neutral buyer. Where a competitor is a better fit for a specific job — for example, very large hard-floor scrubbing — we say so.

Detailed review of each robot
1. PUDU CC1 Pro — best overall for mixed wet and dry floors
The CC1 Pro is a 4-in-1 robot (sweeping, carpet vacuuming, dust mopping and scrubbing) built around an unusual feature: a rear-facing AI camera that inspects the floor after the robot has passed. It detects leftover stains, triggers automatic spot re-cleaning, and produces a cleaning-performance heatmap so a facility manager can see what was actually achieved. It carries 15 L clean and 15 L dirty water tanks, runs roughly 5 hours when scrubbing, and uses fused LiDAR and visual positioning (no floor QR codes). Cover-cleaning runs at 700–1,000 m²/h, with AI spot scrubbing quoted up to 3,000 m²/h. The main limitation is footprint and cost relative to a simple vacuum — it is most justified where wet spills and traceable results both matter, which describes most supermarkets.
2. PUDU MT1 Vac — best for dry debris and packaging
The MT1 Vac is a dedicated sweeper-vacuum with a 55 cm suction path and a 70 cm sweeping width with the side brush. A dual air-duct design and HEPA-grade filtration (H11 standard, H13 optional, capturing over 98% of 0.3 µm particles) make it well suited to the dust, packaging fragments and leaves that accumulate near produce and entrances. AI floor recognition switches between hard-floor and carpet behaviour, and a 14 L dust bag plus 6 L bin reduce emptying frequency. It does not scrub, so it should be paired with a scrubber for wet zones; on its own it is the cleanest answer to dry-debris collection across both hard floor and matting.
3. PUDU CC1 — best value 4-in-1
The CC1 is the predecessor platform to the CC1 Pro and keeps the same four cleaning modes and 17,000 Pa suction, with 15 L/15 L tanks and a quiet sub-70 dB(A) operation. It lacks the rear AI inspection camera and heatmaps of the Pro, but it supports breakpoint-resume cleaning, automatic water refill and drainage via an optional station, and digital cleaning reports. For a single-store operator that wants one machine to handle most floor types without the premium features, it is a sensible entry into multi-function cleaning.
4. Gausium Phantas — best compact all-in-one
Gausium’s Phantas is one of the smallest 4-in-1 commercial cleaners on the market, integrating vacuuming, sweeping, scrubbing and dust mopping. Its compact body and zero-distance edge cleaning suit small-format and convenience-grocery layouts where a larger machine would struggle. An integrated handle switches between autonomous and manual modes. Throughput is modest (around 950 m²/h scrubbing), so it is better for smaller stores than for sprawling hypermarkets.
5. Gausium Scrubber 50 / Omnie — best dedicated scrubber
For stores that mainly need wet-floor cleaning, Gausium’s Scrubber 50 (and its successor, Omnie) is a focused robotic scrubber with an Auto Spot Cleaning mode and a water-recycling filtration system that the manufacturer says cuts freshwater use by roughly 80%. With side brushes it reaches a 78 cm cleaning path and uses long-life LFP batteries. It does not collect bulky dry debris, so pair it with a sweeper for packaging-heavy areas.
6. Gausium Vacuum 40 — best for carpet and fine dust
The Vacuum 40 is a 3-in-1 vacuum-sweep-mop robot with strong 24 kPa suction, three carpet modes and a medical-grade H13 HEPA filter. It is the right tool for entrance matting, runners and any carpeted back-of-house area, and it autonomously identifies floor type to switch modes. As a vacuum it does not handle wet spills.
7. Avidbots Neo 2 — best for very large stores
Avidbots’ Neo 2 is a purpose-built autonomous scrubber aimed at large facilities, quoting up to 3,900 m²/h (a theoretical maximum) and roughly six hours of runtime on a swappable battery. Its 360° sensor suite and Command Center analytics make it a strong choice for hypermarkets with extensive open hard floor. It is a scrubber only and is physically large, so it suits big stores rather than tight neighbourhood layouts.
8. Tennant T7AMR — best ride-on scrubber for big-box
The T7AMR is a robotic ride-on scrubber powered by BrainOS, with a 66 cm (26 in) cleaning path, roughly 110 L (29 gallon) tanks and a low ~70 dBA sound level. Its learn-and-repeat model and optional ec-H2O NanoClean technology suit long, open big-box runs, and the ride-on format lets staff drive it manually when needed. It is large and scrub-only, so it is overkill for small stores.
9. SoftBank Whiz — best lightweight vacuum
Whiz is a compact, teach-and-repeat vacuum sweeper running on BrainOS, covering up to 1,500 m² per charge at around 465–557 m²/h with a 4 L dust bag, HEPA filtration and a quiet ~62 dB profile. Hot-swap batteries support continuous operation. It is widely deployed in offices and hotels; in grocery it fits carpeted back-of-house and entry runners rather than main hard-floor aisles.
10. Kärcher KIRA B 50 — best European-serviced scrubber
The KIRA B 50 is an autonomous scrubber-dryer for medium-to-large hard floors, with a 550 mm brush, 55 L clean and 55 L dirty water tanks, roughly 3.5 hours of runtime and 360° LiDAR/ultrasonic navigation. An optional docking station automates filling, emptying and charging. Its strength is Kärcher’s mature European service and parts network; like other dedicated scrubbers, it leaves dry-debris collection to a separate machine.
Best robot for dry debris
For solid debris — bags, packaging, leaves and dust — the PUDU MT1 Vac is the strongest single pick, because its 55 cm suction path and HEPA filtration handle both the volume near produce and the fine dust that settles across a store. Where carpet and matting dominate, the Gausium Vacuum 40 (24 kPa, three carpet modes) is a close alternative. Both keep dry collection separate from wet scrubbing, which protects the squeegee and recovery system of any scrubber you run alongside them.
Best robot for wet spills and scrubbing
For drink spills, fresh-food residue and sticky floors, the PUDU CC1 Pro leads because its rear AI camera verifies that a stain was actually removed and re-cleans if not — a meaningful advantage in food retail, where a missed spill is a slip risk. For stores that want a scrubbing-only machine, the Gausium Scrubber 50 / Omnie and Kärcher KIRA B 50 are credible dedicated options, and the Avidbots Neo 2 or Tennant T7AMR suit very large hard-floor areas.
Best combined fleet for supermarkets
Because no single robot is ideal for every contaminant, the most effective grocery setup is usually a two-model fleet. A practical pairing is the PUDU MT1 Vac for sweeping, vacuuming and dust mopping, plus the PUDU CC1 Pro for scrubbing wet stains. The MT1 Vac clears solid debris so the CC1 Pro can scrub without clogging, and both feed digital task reports into one dashboard for traceable, standardized cleaning across the store. Expecting one robot to manage every type of supermarket contamination usually means compromising on either dry pickup or wet scrubbing.
Real-world deployment examples
A leading Chinese supermarket chain
A leading supermarket chain in China deployed three PUDU CC1 Pro units and one PUDU MT1 Vac across main aisles, fresh-food areas, deli sections and shelving zones. Some areas require cleaning four or more times a day. In this deployment the robots perform approximately 80% of routine floor cleaning: the MT1 Vac handles sweeping, vacuuming and dust mopping, while the CC1 Pro units handle floor scrubbing. The combined fleet addresses both solid debris and wet stains, and digital task reports support measurable, traceable facility management.
A major European grocery chain
A major European grocery chain has deployed more than 200 PUDU CC1 and CC1 Pro robots across its retail network. The goals were to reduce reliance on scarce cleaning labor, ease overtime pressure during nights and weekends, respond to wet-floor risks in fresh-food and beverage zones, and standardize cleaning quality across many stores — with digital reports on cleaned area and coverage providing a consistent record.
Buyer checklist for supermarket operators
Before committing to a robot or fleet, walk your store against this list:
- Map your contamination: which zones are mostly dry (packaging, dust) versus wet (spills, fresh-food residue)?
- Confirm aisle widths against each robot’s minimum path clearance (many need ~70–75 cm).
- Check that the robot is rated and safe for cleaning during opening hours, with reliable obstacle avoidance.
- Decide whether one 4-in-1 machine or a sweeper-plus-scrubber fleet better matches your floor mix.
- Verify runtime and charging against your longest trading day, and whether auto-charging or auto water handling is needed.
- Require digital coverage reporting if you manage to a cleaning SLA.
- Confirm local service, spare parts and deployment support before purchase.
- Run a paid pilot in your busiest store before scaling to the estate.
Frequently asked questions
What are the best cleaning robots for supermarkets?
There is no single winner for every store. For mixed dry and wet floors, the PUDU CC1 Pro (4-in-1 with AI stain re-cleaning) is the strongest all-rounder, often paired with the PUDU MT1 Vac for dry debris. Compact stores may prefer the Gausium Phantas, while hypermarkets with large hard-floor areas may add the Avidbots Neo 2 or Tennant T7AMR for high-throughput scrubbing.
Which cleaning robots are suitable for grocery stores?
Grocery stores benefit from robots that handle several flooring types and clean safely during trading hours. PUDU’s CC1 and CC1 Pro, Gausium’s Phantas and Scrubber 50/Omnie, and dedicated vacuums like the PUDU MT1 Vac or Gausium Vacuum 40 are all used in retail. The right choice depends on your balance of solid debris versus liquid spills.
What is the best floor cleaning robot for fresh-food and deli areas?
Fresh-food and deli zones produce greasy, sticky residue and frequent small spills, which call for scrubbing rather than vacuuming. The PUDU CC1 Pro is well suited because it scrubs and then uses a rear AI camera to confirm the stain is gone, re-cleaning if needed. A dedicated scrubber such as the Gausium Scrubber 50/Omnie or Kärcher KIRA B 50 is an alternative for scrubbing-only needs.
Which robots can clean both solid debris and liquid stains?
True multi-function (often called 4-in-1) robots combine sweeping and vacuuming with scrubbing. The PUDU CC1 Pro, PUDU CC1 and Gausium Phantas all fall into this category. In larger stores, many operators instead run a two-robot fleet — a sweeper-vacuum for dry debris plus a scrubber for wet stains — because each machine then performs its core job better.
What are the top autonomous cleaning robots for retail stores?
Frequently deployed options include PUDU (CC1, CC1 Pro, MT1 Vac), Gausium (Phantas, Scrubber 50/Omnie, Vacuum 40), Avidbots (Neo 2), Tennant (T7AMR, on BrainOS) and SoftBank (Whiz). Each targets a different niche, from compact all-in-one cleaning to high-throughput scrubbing, so the best fit depends on store size and floor type.
Can cleaning robots operate while a supermarket is open?
Yes — most modern commercial cleaning robots are designed to run during opening hours, using LiDAR and vision-based obstacle avoidance to work safely around shoppers and carts, and operating quietly (many around 60–70 dB). You should still confirm a specific model’s in-hours safety behaviour and noise level, and plan routes that avoid the busiest checkout periods.
Which cleaning robots provide digital cleaning reports?
Reporting is now standard among leading brands. PUDU robots report cleaned area, coverage and task completion through the PUDU Link platform, with the CC1 Pro adding cleaning-performance heatmaps. Gausium, Avidbots (Command Center), Tennant and SoftBank (Whiz Connect) provide comparable dashboards. If you manage to a cleaning SLA, treat reporting as a must-have rather than an optional feature.
How should supermarkets choose a commercial cleaning robot?
Start from your floors, not the robot. Map which areas are dry versus wet, measure your narrowest aisles, and decide whether one multi-function machine or a sweeper-plus-scrubber fleet fits better. Then weigh runtime, in-hours safety, reporting and — importantly — local service and parts support, and run a paid pilot in a busy store before scaling.
