Keenon Kleenbot C20

Where the C20 sits in the KLEENBOT line

The Keenon Kleenbot C20 is the smallest model in the KLEENBOT family. KEENON announced it alongside the C40 and C55 in the same launch as the XMAN-R1, on 31 March 2025.

In that press release KEENON describes the C20 plainly: its 35 cm slim body lets it reach dust-accumulation spots, making it suited to compact spaces such as convenience stores and offices. The same release notes the dual-tank system (clean and dirty water kept separate) and a modular design that lets side brushes and the dust box be pulled out and swapped quickly.

Verified specifications

Every line below comes from the “Product Parameters” table on KEENON’s own C20 product page, except where another source is named.

Specs with no public source: KEENON does not publish the C20’s suction power (Pa), travel speed, obstacle-crossing height, minimum passage width, noise level, IP rating or coverage per charge. It is worth noting that the company publishes several of these for the C20’s siblings — the C30’s suction is 19,000 Pa, the C30’s top speed is 0.8 m/s, and the C40’s minimum pass-through is 65 cm — but not for the C20. Some dealer pages list “60 cm minimum passage width” and “2,000 m² per charge”; we could not confirm either with KEENON, so they stay out of the table. If those numbers decide your purchase, get them in writing from the distributor.

The “35 cm” is height, not width

This one gets misread often, because the KLEENBOT line is otherwise named after cleaning width (C40 = 40 cm scrubbing, C55 = 55 cm). The C20’s “35cm Ultra-Slim Body” is not a width — it is the 351 mm body height, per the 523 × 400 × 351 mm dimensions KEENON publishes, and the company captions it “Perfect for Compact & Low-Height Spaces”.

In practice that means the C20 gets under desks, shelving and counters that the rest of the line cannot: the C30 is 750 mm tall and the C40 is 690 mm, roughly twice the C20’s height. Its actual working widths are 450 mm sweeping/vacuuming and 285 mm scrubbing — the narrowest in the line.

Against the C30, C40 and C55

All figures come from KEENON’s own product pages, except the C55 column, which comes from the press release (KEENON has not published a weight or dimension table for the C55).

What the table shows is that the C20 is not simply a smaller version of the same machine — it is a genuinely different weight class. At 22 kg against the C40’s 70 kg, one person can lift it into a vehicle or carry it up a step, which is not true of the C40. The trade is equally blunt: 400 m²/h is a quarter of the C40’s rate and a sixth of the C55’s.

Who should skip this one

• Anything much beyond a few hundred square metres. At 400 m²/h with a 4-hour maximum runtime and a 3-hour recharge after it, the C20 is not built for malls or warehouses. That is what the C40 and C55 are for.
• Floors with carpet. KEENON positions the C20 for hard floors. The model the company positions for dry cleaning from marble through to carpet is the C30.
• Heavily soiled or greasy floors. A 7 L clean water tank, a 0.66 L dust bin and a 285 mm scrubbing width are the specs of routine daily upkeep, not a deep clean. If your kitchen or plant floor needs genuine scrubbing, look at a model with a real scrubbing deck.
• Anyone filling in a tender or TOR spec sheet. Suction, speed, noise, IP rating and passable corridor width have no published KEENON figure for this model. If your paperwork requires those fields, get written confirmation from the distributor first.

On price

KEENON announces no price for the C20 — its product page on keenon.com carries only a contact form (with “Purchase Product” and “Become our Distributor” options), no purchase price and no monthly rental.

We found no baht price from an official Thai distributor or from any Thai retailer’s own website as of 6 August 2026. Some overseas dealer pages do carry figures, but the ones we found contradict each other by a factor of roughly two, are not numbers KEENON published, and carry no date we could verify — so we neither quote them as a price nor convert anything into baht. A real figure has to come from a distributor’s quotation.
