Cordless, 1.8 gallons, one filter for both jobs — battery not included.
Where this ends up The only cordless machine here, and the only one whose filter handles wet and dry without being swapped — which is the mistake that kills these vacuums. A hundred and seventy-three dollars for one point eight gallons, with the battery and charger sold separately.
“The top-mounted cartridge filter ensures seamless cleaning without removing the filter - no matter if wet or dry dirt.”
This solves the problem that quietly destroys wet/dry vacuums, and no other machine on this shelf does.
Everywhere else you need two filters and you must change between them. A cartridge filter traps fine dust and is ruined the moment water passes through it — it clogs, sags, and then passes dust straight to the motor. A foam sleeve handles water and traps almost no dust.
Two listings supply both, and one explains why. The Vacmaster VOC508S at $74.99: “a cartridge filter for dry pick-up and a foam wet filter for wet pick-up.” The Armor All AA255W at $67.71 lists a “reusable cloth filter” and a “foam wet filter” without saying what either is for.
And eight listings here name one filter or none. The Craftsman 17250 at $44.99 includes a “Filter Bag” — dry-only — on a machine sold as wet and dry.
So the single most likely way to ruin a vacuum on this shelf is to pick up a spill with the wrong filter fitted, and this is the only machine where you cannot.
Top-mounted is the other half of the sentence. You reach the filter from above rather than into a drum that has just held water, which is both cleaner and the reason the no-swap claim is practical rather than theoretical.
“The compatible Kärcher 18V battery and charger are available separately.”
$172.99 buys the vacuum, a 3.9 foot hose, two nozzles, a filter bag and a cartridge filter. It does not buy anything to run it.
That makes this the third most expensive machine on this shelf for 1.8 gallons of capacity, before the battery.
The arithmetic worth doing before ordering:
If you already own Kärcher 18 V packs — from a pressure washer, a blower, a garden tool — this is a sensible addition to a system, and the price is for a tool rather than a kit.
If you do not, add a battery and charger and compare with what else is here. The Vacmaster VOC508S at $74.99 gives 5 gallons, a stainless steel tank and a published 135 air watts. The Armor All AA255W at $67.71 gives 2.5 gallons and thirteen accessories including both filters.
Worth noting, as a sign of how carefully the page was written: the set list ends “filter bad, and a cartridge filter.”
“ideal for car vacuuming or cleaning tasks with no power plug around.”
That phrase is the product.
Every other machine on this shelf measures its reach as hose plus cord from a socket:
Bissell 18P03 — a 32 ft hose · Giraffe Tools ×2 — 30 ft retractable · Vacmaster VFB511H — “25 feet of cleaning reach” · Craftsman 17040 — 22 ft · Armor All AA255W — 18 ft · Shop-Vac and Vacmaster VOC508S — 16 ft · Armor All AA155 — 10 ft
This has no socket, so its reach is wherever you can carry 3629 g (128 oz): a driveway with no outside power, a boat, a caravan, the far end of a garden, a car park.
The 3.9 foot hose is the shortest here — the next is the Craftsman 17250 at 5 feet — and on a corded machine it would be crippling. Here it simply means the vacuum comes with you, which it was always going to.
What the listing does not publish is runtime, and on a cordless machine that is the figure you most need. An 18 V pack driving a vacuum motor is measured in minutes rather than hours — and 1.8 gallons is probably the drum one battery can fill.
1.8 gallons is the second smallest on the shelf, above only the Armor All AA155 at 1.5:
Armor All AA155 1.5 · this 1.8 · Armor All AA255W and Craftsman 17250 2.5 · Craftsman 17040 and Bissell 18P03 4 · Giraffe Tools ×2 4.5 · Vacmaster ×2 and Shop-Vac 5 · Bissell 2035M 6
And every one of those figures describes a drum, not a fill line — a point only the Craftsman 17250 admits: “gallons indicated reflect drum volume, not necessarily [usable capacity]”. The motor and filter take the top, and on wet work nobody fills to the brim because water reaching the motor is the one fault that ends the machine.
So read 1.8 gallons as a car’s worth of debris, or a modest spill. Which matches the nozzles supplied.
Upholstery and crevice, “for convenient cleaning of seats, trunks, or small spaces between consoles or car seats.”
That is a car kit, and the honest reading of this machine is that it is a car vacuum with wet capability rather than a shop vac.
For comparison on accessory count: the Armor All AA255W publishes thirteen, the Vacmaster VFB511H nine, the Bissell 18P03 seven, the Armor All AA155, Vacmaster VOC508S and both Giraffe Tools machines six, the Craftsman 17250 four, and this two.
No floor tool and no wand are included, which rules out most garage-floor work regardless of the drum size. The Armor All AA255W ships three extension wands and a floor brush/squeegee nozzle, which is the tool for standing water.
“Use the blower function to remove loose dirt from hard-to-reach surfaces or to collect loose scattered leaves.”
Six of twelve machines here convert to a blower: both Armor All models, both Bissells, the Craftsman 17250 and this.
On a cordless machine it is a better feature than on a corded one, because blowing is the job you most often want to do away from a socket — a doorway, a patio, the footwell of a car on a driveway.
No air watts, no kPa, no amps — nothing that lets you judge the suction.
What the rest of the shelf gives: the Vacmaster VFB511H publishes 320 air watts and 20 kPa, the VOC508S 135 air watts, both Giraffe Tools machines 20 kPa, the Bissell 2035M 11 amps, the 18P03 12 amps. Seven listings publish only peak horsepower, which is not a power figure at all — 5.5 PHP is 4100 W where a 120 V socket supplies about 1800 W.
A battery machine cannot quote peak horsepower credibly, so publishing nothing is at least consistent. It is still nothing.
No runtime, as above.
No battery capacity or charge time.
No filtration rating. The Vacmaster VFB511H is the only listing here that quantifies it, at 1 micron.
No warranty. Both Craftsman machines publish 3 years and both Giraffe Tools machines 24 months. The other eight, this included, publish none — which on a machine costing $172.99 before its battery is worth noticing.
No drain and no fill indicator, though at 1.8 gallons the first matters less. The Shop-Vac has a “bottom drain outlet”; the Bissell 18P03 has an “LED Full Water Tank Indicator”.

No, and the listing says so in its last line: "The compatible Kärcher 18V battery and charger are available separately." So $172.99 buys the vacuum, a 3.9 foot hose, two nozzles, a filter bag and a cartridge filter — and nothing to run it. That makes this the third most expensive machine on the shelf for 1.8 gallons of capacity, before you have bought the thing that makes it work. The arithmetic to do before ordering: if you already own Kärcher 18 V batteries from a pressure washer or a garden tool, this is a sensible addition to a system. If you do not, add a battery and a charger to the price and compare it with what else is here — the Vacmaster VOC508S at $74.99 gives 5 gallons, a stainless tank and a published 135 air watts, and the Armor All AA255W at $67.71 gives 2.5 gallons and thirteen accessories. The listing also contains a small typo worth noting as a sign of care: the set list ends "filter bad, and a cartridge filter."
Because swapping filters is the thing most people get wrong, and it destroys the machine. The bullet reads: "The top-mounted cartridge filter ensures seamless cleaning without removing the filter - no matter if wet or dry dirt." On every other machine on this shelf you need two filters and you must change between them. A cartridge filter traps fine dust and is ruined the moment water passes through it: it clogs, sags, and then lets dust straight into the motor. A foam sleeve handles water and traps almost no dust. Two listings supply both and one explains why — the Vacmaster VOC508S states "a cartridge filter for dry pick-up and a foam wet filter for wet pick-up", and the Armor All AA255W lists a "reusable cloth filter" and a "foam wet filter". And eight listings here name one filter or none: the Craftsman 17250 includes a filter bag, which is dry-only, on a machine sold as wet and dry. So this Kärcher removes the decision. Top-mounted is the other half — you reach the filter from above instead of into a wet drum.
In a car, yes, because there is no cord to trip over and the machine comes with you. It is the shortest hose on the shelf by a margin — the next is the Craftsman 17250 at 5 feet — and on a corded machine that would be crippling. Here the arithmetic is different: every other listing’s reach is hose plus cord, measured from a socket. Bissell 18P03 has a 32 ft hose, both Giraffe Tools machines a 30 ft retractable one, the Vacmaster VFB511H publishes "25 feet of cleaning reach", the Armor All AA155 manages just 10 feet from a 6 ft cord and a 4 ft hose. This machine has no socket at all, so its reach is wherever you can carry 3629 g (128 oz) — which is a driveway without power, a boat, a caravan, or the far end of a garden. That is the case for it, and it is a real one. What the listing does not publish is runtime, which on a cordless machine is the figure you most need. An 18 V pack driving a vacuum motor is measured in minutes, not hours, and 1.8 gallons is probably the right drum for one battery.
