The Pudu SH1 is a smart upright scrubber-dryer that combines the deep-cleaning capability of an industrial machine with the simplicity of a mop. Unlike Pudu's larger autonomous cleaning robots, the SH1 is a cordless, walk-behind device an operator pushes by hand. It applies 27 kg (about 55 lbs) of downward brush pressure at 350 RPM and follows with 20,000 Pa of vacuum suction, so floors are scrubbed and left dry in a single pass. Compared with a conventional mop, Pudu states the SH1 reduces cleaning time by roughly 70% and cuts water and detergent use by up to 80%, and it covers 1,100-1,600 m2/hour (about 11,800-17,200 sq ft/hour).
At just 17 kg (about 59 lbs) and 49 x 53 x 120 cm, the SH1 is built for crowded, complex spaces where a full-size scrubber cannot maneuver and where storage room is tight. Multi-surface attachments and a removable squeegee let it clean not only floors but also countertops, vertical glass, mirrors, tiled walls, corners, and the gap under low furniture. Its first-to-market wastewater tank uses an air-solid-liquid separation system that splits gases, liquids, and solid debris to prevent drain clogs during disposal. A 4.2-inch touchscreen with visual and audio cues lets staff switch among multiple cleaning modes and review after-cleaning reports on duration, water use, and area covered.
Power comes from an 18 Ah lithium-ion battery delivering up to 70 minutes in standard mode and up to 100 minutes in ECO mode, recharging in about 2.5 hours; batteries are hot-swappable for continuous shifts. As the lowest-cost entry point in the Pudu cleaning lineup, the SH1 fits operators who want professional scrub-and-dry results without the price or footprint of an autonomous floor robot. RobotLAB sells, deploys, trains staff on, and services the SH1 nationwide, and can also place it on a monthly RaaS subscription.

Grease, oil spills, and dried food residue make restaurant floors some of the hardest to keep safe. The SH1's 27 kg brush pressure and 350 RPM scrubbing tackle oily, sticky buildup, while 20,000 Pa suction leaves the floor dry behind it to reduce slip hazards during service. Its compact 44 cm cleaning path fits between prep stations, behind counters, and into kitchen corners a full-size scrubber cannot reach, and vertical-surface attachments clean tiled walls and display glass.
For retail aisles, auto service bays, and dealership showrooms, the SH1 delivers fast scrub-and-dry passes without the floors-are-wet downtime of mopping. At 17 kg and cordless, staff can move it across departments and store it in a small closet. The 1,100-1,600 m2/hour throughput keeps mid-size floors presentable through the day, and after-cleaning reports document coverage for facility managers.
In clinics, senior-living communities, gyms, and K-12 or higher-ed buildings, leaving floors wet is a fall risk for vulnerable occupants. The SH1 dries as it scrubs, cutting that hazard, and its low 69-72 dB(A) operating noise makes it usable in occupied corridors and common areas. Up-to-80% reductions in water and detergent support facilities working toward lower chemical use and resource consumption.
Hotels, spas, and arts or entertainment venues need frequent spot cleaning of lobbies, restrooms, bars, and back-of-house areas without disrupting guests. The SH1's compact upright form and quiet operation let housekeeping teams clean on demand throughout the day, and hot-swappable batteries keep it running across long event or shift schedules. Pudu has deployed the SH1 in hospitality settings including spa hotels.

The Pudu SH1 is a smart upright scrubber-dryer: a cordless, walk-behind cleaning machine an operator pushes by hand. It scrubs and dries floors in a single pass using 27 kg of brush pressure at 350 RPM plus 20,000 Pa of suction. Note it is a manual device, not one of Pudu's autonomous cleaning robots, which makes it the most affordable entry point in the Pudu cleaning lineup. RobotLAB sells, deploys, and services it nationwide.
27 kg brush pressure, 350 RPM brush speed, 20,000 Pa suction, and 1,100-1,600 m2/hour (about 11,800-17,200 sq ft/hour) productivity. It has 4 L clean and 4 L wastewater tanks, an 18 Ah hot-swappable lithium-ion battery good for up to 70 minutes standard or 100 minutes in ECO mode, a 2.5-hour recharge, a 44 cm cleaning width, a 4.2-inch touchscreen, and weighs 17 kg (about 59 lbs). It runs at 69-72 dB(A).
RobotLAB lists the Pudu SH1 at a $3,800 purchase price, with a $3,500/month RaaS subscription and a $79/month financing option also available. RobotLAB sells, leases, deploys, trains your staff, and services the unit nationwide. Call 1-87-RobotLAB for a current quote and to confirm what is included with purchase versus subscription.
The SH1 is a manual upright scrubber an operator pushes, while the Pudu BG1 scrubber-dryer and CC1 are fully autonomous floor robots that navigate and clean on their own. The SH1 wins on price (about $3,800 versus roughly $22,000+ for autonomous models) and on reaching tight, cluttered spots, countertops, and vertical surfaces. The autonomous robots win on large open-floor productivity and hands-free operation. Many facilities run an autonomous robot for big floors and an SH1 for detail and edge cleaning.
Operators who want professional scrub-and-dry results without the cost or footprint of an autonomous robot. It fits restaurants and kitchens, retail and auto service centers, healthcare and assisted-living facilities, gyms, schools, hotels, and entertainment venues, especially where floors are crowded, storage is tight, or staff need to clean floors and vertical surfaces with one device.
No. The SH1 is a manually operated upright scrubber-dryer that a person walks behind and steers, similar to using a powered mop. It is smart in that it has a touchscreen, multiple cleaning modes, and after-cleaning reporting, but it does not self-navigate. If you need hands-free autonomous cleaning, RobotLAB can recommend Pudu's robotic cleaners such as the CC1 or BG1.
Yes. RobotLAB can arrange a demo and help you decide between the manual SH1 and an autonomous cleaning robot based on your floor type, square footage, and staffing. Call 1-87-RobotLAB to schedule a demonstration or request a quote.
