Ron Resnick posed this question to me in the thread

Horizontal machines are primarily vacuums, where fluid is applied automatically or manually and the fluid is agitated on the platter by hand or by a brush held by the machine as the record is rotated by the machine. Then vacuum is applied to remove the fluid. Better models of these use a point-nozzle rather than a slot for their vacuum, such as those from Keith Monks and Loricraft.
Until the rise of ultrasonic cleaning, the horizontal machines held sway. To my knowledge, there have been no new horizontal vacuums come on the market in the last several years. Existing manufacturers continue to offer the same machines they have offered for some time now, with maybe form factor or cosmetic changes.
The latest offering I know for ~$450 with a motor is the Pro-Ject VC-S2. or here. Keith Monks and the Loricrafts are a good bit more expensive.
However there are manual options where the end-user turns the record, applies and agitates fluid and the machine does the vacuuming.
Perhaps the most famous of these is the Nitty Gritty. I owned their initial 1.0 basic model in the early 2000s. They have added automation to various models. Their Mini-Pro automatically rotates, wets, scrubs, and vacuum both sides of the record at the same time, msrp $1650. BUT, their original model 1.0 is still available for ~$475. The VPI 16.5 is similar but does have a noisey motor for turning the record along with a slotted vacuum. A fancy, nicer machine of this type is the Clearaudio Smart Matrix Silent for ~$2800.
An even more rudimentary version of the original Nitty Gritty is the Record Doctor VI for ~$300.
The issue, imo, with slotted vacuums is how the slot comes in contact with the record. On either side of the slot are 'lips' of various material. Nitty Gritty uses velvet. These lips contact the record surface. Any bit of particulate can be trapped in the material lips and thus dragged against the record as it turns. The lips wear out fairly quick and must be replaced. I cannot recommend slotted vacuums for that reason.
Cheaper yet is the Spin-Clean which holds the record horizontally in a bath and the user turns the record. Fluid is removed with a cloth, so no vacuum. ~$125.00
As mentioned in post #142 above, the Humminguru is a cheap ultrasonic cleaner for $350. I have not used it.

System for Under US$10,000 MSRP
How can that possibly fit in the specified budget? Can I tell him you'll buy it for him? You can tell him anything you want, Ron. I responded to your choice. Regardless of cost, it wasn't a good one.

Serious question: is there any decent record cleaning machine in the <$500 range which operates like the VPI 16.5 (squirt liquid, rotates record, vacuumed up by a tube)?
