A beater bar is not forbidden as often as you think

Of the 172 entries in this register, 98 rule on a vacuum with a beater bar, a rotary brush head, a floor scrubber or a buffer. 68 say nothing about any of them and 6 rest on documents whose bytes never reached us. That much the register already prints, entry by entry.

What it cannot print is the difference inside the 98. A publisher who writes “Do not use vacuum with beater bars” has given the reader a rule. A publisher who writes “Damage caused by vacuum cleaner beater bar” in a list of what the warranty declines to cover has given the reader no rule at all — nothing is forbidden, and a claim is. Both land in the same cell, because a cell records a refusal and both are refusals. They are not the same thing to somebody standing over a vacuum deciding whether to switch it on.

27 documents in this corpus rule on the machine and never once instruct against it. Every sentence they carry about it is an exclusion.

What kind of sentence each one is

Measured over the publishers' own bytes, not over our summaries. Running a pattern across our own reading of a document would label the reading rather than the document, and a reader would get the label with nothing behind it. 172 rulings in total; a document can carry more than one.

Class Rulings What it means for a reader
instruction 107 The publisher instructs the reader — a rule, in the second person.
exclusion 46 The machine appears only in what the warranty declines to cover. Nothing is forbidden; a claim is.
both 15 Both, in one document: instructed against AND excluded from cover.
warning 1 Warned about and neither instructed against nor excluded. The reader is told what can happen and left to decide.
unclassified 0 None of the three. Held open rather than filed under the nearest.
unlocated 3 The quotation is not in the document’s text layer, so nothing was measured and nothing is claimed.

No ruling fell outside the three classes. That zero is only worth reading because the measurement carries a control sentence built to belong to none of them — without it, a run in which every pattern had quietly stopped matching would report the same tidy zero. 47 documents instruct and never place the machine in an exclusion.

The 27 that never tell you not to

Every located sentence these documents carry about the machine sits inside what the warranty declines to cover. A document with even one instructing sentence anywhere in it is not here, whatever else it also says.

Where a condition is attached

A conditional ruling is a permission with a qualifier, and the qualifier is the part that decides a claim. These are the conditions as the record states them, with the brands whose documents state each.

Condition Rulings Brands
the vacuum head must be a felt brush type 40 Bellawood, CoreLuxe, Dream Home, Duravana
the vacuum must use tools designed for hard surfaces 6 Home Decorators Collection, Mohawk, Pergo
the vacuum must be run without its beater bar 1 LifeProof

By brand

A brand whose documents disagree with each other appears with both numbers rather than with whichever its first document said. Several brands here serve more than one live document for one product line, with no canonical index and no redirect between them.

The one that only warns

Raised, and neither instructed against nor excluded from cover. The reader is told what can happen and left to decide — which is a third answer, and the register has no cell for it.

CAUTION: Vacuum cleaners with beater bar or unprotected power rotary brush head can damage the floor.

How this was measured

Each quotation was located in its own document and the 700 characters in front of it were read for the heading of an exclusion. The sentence itself was read for an instruction and for a warning. Every pattern below had to match a control string and had to fail to match its opposite before any of this ran: a pattern widened until it matches everything passes a one-sided control exactly as a correct one does.

Set Pattern Must match Must not match
exclusion/not-covered \b(?:does not cover|is not covered|are not covered|not covered (?:by|under)|shall not (?:be )?cover)\b This warranty does not cover damage from misuse. This warranty covers manufacturing defects for twenty-five years.
exclusion/exclusion-heading \b(?:exclusions?|excluded|what is not covered|not warranted|does not warrant)\b EXCLUSIONS: the following are not the manufacturer’s responsibility. The following conditions are included for the life of the floor.
exclusion/damage-caused-by \bdamage(?:s)? (?:caused by|resulting from|due to|from)\b Damage caused by vacuum cleaner beater bars is not the responsibility of the maker. Sweep the floor to remove grit before it can abrade the finish.
exclusion/voids-warranty \b(?:void(?:s|ed)? (?:the|this|your) warranty|will void|voiding)\b Use of a floor scrubber voids the warranty in its entirety. Use of a felt brush head is recommended for daily cleaning.
instruction/negative-imperative ^\s*(?:do not\b|don.t\b|never\b|avoid\b|no\b(?!\w)) Do not use vacuum with beater bars / very hard bristles. The warranty does not cover damage caused by a beater bar.
instruction/negative-modal \b(?:should (?:never|not)|must not|may not|is not to be|are not to be|should be avoided|not be used|not recommended)\b Vacuums with a beater bar should never be used on wood flooring. Damage caused by caster wheels or vacuum cleaner beater bars.
instruction/positive-imperative ^\s*(?:use|clean|sweep|vacuum|regularly|for day to day|only use)\b Use vacuum tools designed for hard surfaces. Damage resulting from the use of rotating beater bars.
warning/can-damage \b(?:can|may|could|might)\s+(?:damage|scratch|scuff|mar|harm|dull)\b CAUTION: Vacuum cleaners with beater bar can damage the floor. A beater bar will void this warranty.

What this page does not know

  • Whether an exclusion is safe to ignore. It is not permission. The floor can still be marked, the mark is still the reader's, and the only thing the publisher has said is who will not be paying for it.
  • Which document governs a particular floor. Several brands here serve more than one live document for one product line, with no canonical index and no redirect between them. The document in the reader's own paperwork is the one that decides.
  • Whether 3 quotations here was classified at all. They could not be located in their own document: the file is type converted to outlines and has no text layer, so its cells were read by eye and no pattern could be run over them. They are counted here rather than dropped, and nothing is claimed about them.
  • Whether a publisher has answered somewhere we did not look. This is a reading of 96 documents that rule, not of everything a brand has published. A phone line, a support article and a dealer's answer are all outside it.

Quotations are reproduced verbatim and kept short — the longest on this page is 295 characters, against a ceiling of 600. No manufacturer document is rehosted here; every credit line links to the publisher's own copy. The column is donerFirca in the register.
